ANATEL Brazil: certification and Homologation Number

Hugues Orgitello updated 9 Oct 2026 23 min read

ANATEL homologation is the legal prerequisite for using or selling a telecommunications product in Brazil, which in practice means anything that transmits or receives radio signals or connects to a telecommunications network. The rules sit in a short stack of texts: the Lei Geral das Telecomunicações 9.472/1997, the Regulation approved by Resolução 715/2019 (amended by Resolução 780/2025), and a set of ANATEL acts (Ato) that fix the procedures and the technical requirements. This guide reads those texts directly: who may apply, how a designated certification body (OCD) and a laboratory are chosen, what the twelve-digit homologation code must look like on the product, which EMC levels apply, how often the certificate must be maintained, what changed in 2025 and 2026, and which common claims about ANATEL the texts do not support.

Legal and institutional frame

ANATEL (Agência Nacional de Telecomunicações) was created by article 8 of the Lei Geral das Telecomunicações 9.472/1997, as a body of the indirect federal administration under a special autarchic regime, linked to the Ministry of Communications. Article 19, item XIII, gives it the power to issue or recognise the certification of products, against the standards it sets. Its remit is much wider than products: spectrum, licensing and the regulation of telecommunications services.

For products, the operative text is the Regulation on conformity assessment and homologation of telecommunications products, approved by Resolução 715/2019. Article 55 makes homologation a mandatory prerequisite for using and selling the products it covers. The Regulation is deliberately general: article 22 delegates the detail to two kinds of complementary act, both issued by the competent Superintendency after public consultation:

• operational procedures, which fix how the process runs (certification, marking, laboratories, imports);
• Requisitos Técnicos, which fix the parameters a product type must meet and the conformity assessment models open to it (article 26).

ANATEL does not test products itself. Article 6 assigns that work to the Organismos de Certificação Designados (OCDs) and to habilitated test laboratories. Article 93 keeps technical rules issued before the Regulation in force until they are expressly replaced, which is why a 2018 EMC act and a 2017 radio act still matter in 2026.

Product classification, and the three categories you will still be quoted

Almost every summary of ANATEL still opens on three product categories. Resolução 715/2019 does not use the word "Categoria" anywhere, and the classification those summaries describe was repealed in 2020.

Where the categories came from, and when they stopped applying

The Category I, II and III scheme is defined in article 3, items XVIII to XX, of Resolução 242/2000. Article 3 of Resolução 715/2019 repealed that resolution, and Resolução 323/2002 with it, 180 days after publication.

It is also routinely described backwards. Against the definitions in Resolução 242/2000 itself:

Category	Resolução 242/2000 article 3 definition	Conformity assessment it attracted
I	Terminal equipment intended for use by the general public to access a collective-interest telecommunications service	Certificate with quality-system assessment, article 26, the heaviest of the three
II	Equipment not covered by Category I that uses the radio spectrum to transmit signals, including antennas and equipment characterised in specific regulation as restricted-radiation radiocommunication equipment	Certificate with type tests and periodic product assessments, article 25
III	Any product not falling under Categories I or II whose regulation is necessary, for instance to guarantee interoperability of the networks supporting the services	Certificate based on type testing, article 24

A Wi-Fi, Bluetooth or cellular module was therefore Category II, not Category I.

Where the words still appear

The categories are gone as a classification, but not from every text in force. Because article 93 keeps older technical rules alive, the EMC requirements approved by Ato 1120/2018 still say, in item 3.1.2, that the immunity requirements apply to products of Category I and Category II intended for the general public. Reading that act today means mapping the old words onto the product: a consumer radio product still falls inside the immunity scope.

What actually determines your route today

Resolução 715/2019 organises the work by conformity assessment model rather than by category. Article 29 lists the models (declaration of conformity, declaration with test report, certification on type test, with periodic product assessment, and with factory management system assessment, plus labelling and others), and article 32 says that products used directly by end users, and transmitters using spectrum for collective-interest services, should preferably go through certification.

The model and the technical requirements for a given product are read off the Lista de Referência de Produtos para Telecomunicações, approved by Ato 7280/2020 and updated since (Ato 9960/2024 and Ato 5314/2026 added product types). The OCD must classify the product against that list and tell the applicant which requirements apply and which must be tested (Ato 4083/2020, items 6.2.1 and 6.2.3).

Who may apply

Article 20 of the Regulation lists three possible applicants: the manufacturer, the commercial representative of a foreign legal entity, and any person homologating for own use. Its first paragraph is the rule that shapes every foreign project: except where the Regulation provides otherwise, the homologation request can only be made by a person with full civil capacity resident in Brazil, or a legal entity constituted under Brazilian law, so that someone can answer for the product on Brazilian territory. Article 21 adds that a legal-entity applicant selling in Brazil must show it can honour Brazilian consumer rights, including product information, warranty and technical assistance.

The Brazilian party is not a formality that ends at filing:

• under Ato 4088/2020, item 5.3, the legal representative of the manufacturer is responsible for marking imported products;
• under Ato 18086/2025, item 6.2, only the homologation holder or its legal representative may import the homologated product for sale, and the importer must enter the homologation code in the import declaration (item 6.4);
• under article 73, item VIII, the homologation may be revoked if the foreign manufacturer withdraws the commercial representation.

Homologation rights can be assigned or shared (article 20, third paragraph), but an assignment takes effect only once ANATEL issues a homologation certificate in the name of the new holder (article 66), and a shared right to sell must say how consumer warranty and assistance are handled (article 67).

Role of the OCDs, and how the laboratory is chosen

An OCD is designated by ANATEL (article 7). Under article 8 it must be either a legal entity accredited by Inmetro for telecommunications product certification, or a foreign certification body recognised through a mutual recognition agreement. It conducts every certification route (article 36), cannot certify a product its staff helped develop or advised on (article 37), and issues the Certificado de Conformidade, which the applicant then submits to ANATEL for homologation.

The laboratory is chosen by the applicant (article 18), within the order fixed by Ato 4091/2020. Tests must be run by a third-party laboratory habilitated by ANATEL with a scope covering the product (item 5.2), in this order of preference (item 5.3):

Order	Laboratory	Condition
a	Third-party lab in Brazil	Accredited by Inmetro, or recognised under a mutual recognition agreement
b	Third-party lab in Brazil	Assessed by an OCD with scope to assess laboratories
c	Third-party lab abroad	Accredited by the official body of its country, signatory of the ILAC arrangement (since January 1, 2026 the Global ACI MRA covers the former ILAC MRA scope)
d	Non-third-party lab (for instance a manufacturer lab)	Accredited by the official body of its country; the OCD must witness the tests (item 5.3.2)
e	Non-third-party lab	Assessed by an OCD; the OCD must witness the tests

Moving down the list must be justified and documented (item 5.6). Item 5.4 lists the accepted reasons: the lab does not answer a quotation request within 7 working days; it sets more than 7 working days to start after acceptance and sample delivery; its timing is not compatible with that of foreign third-party labs under equivalent conditions; its scope does not cover all the functional tests of the product; or its test or logistics costs are prohibitive compared with national and foreign labs, in which case ANATEL must be consulted first. A foreign report is accepted only if the lab scope, accredited or assessed abroad, is compatible with the ANATEL technical requirements (item 5.3.1).

For large, complex or low-volume products, the OCD may, with prior ANATEL authorisation, accept tests in the manufacturer or supplier laboratory, witnessed in person (item 5.7).

EMC requirements, parameter by parameter

Unless a product-specific act says otherwise, EMC is assessed against Ato 1120/2018. Its references are older than most readers expect: CISPR 22 (2005) and CISPR 24 (1997, with amendments 1 and 2) rather than CISPR 32 and CISPR 35, and the IEC 61000-4 basic standards in their 2001 to 2004 editions. For radio equipment, the radiated emission limits of the act apply only where no specific regulation sets intentional or spurious emission requirements for the product (item 3.1.1).

Test (Ato 1120/2018)	Basic standard cited	Level	Performance criterion
Conducted emission, power port	CISPR 22 (2005)	Class A: 79/66 dBµV QP/AV (0.15-0.5 MHz), 73/60 (0.5-30 MHz). Class B: 66-56/56-46 dBµV (0.15-0.5 MHz), 56/46 (0.5-5 MHz), 60/50 (5-30 MHz)	n/a
Radiated emission	CISPR 22 (2005)	Class A: 40 dBµV/m (30-230 MHz), 47 (230-1000 MHz). Class B: 30 and 37 dBµV/m	n/a
Electrostatic discharge	IEC 61000-4-2 (2001)	6 kV contact, 8 kV air	B
Radiated RF immunity	IEC 61000-4-3 (2002)	3 V/m, 80-1000 MHz and 1.4-2.0 GHz, 1 kHz modulation	A
Fast transients, 5 kHz repetition	IEC 61000-4-4 (2004)	0.5 kV telecom ports, 1 kV power ports (AC and DC)	B
Surge	IEC 61000-4-5 (2001)	Telecom ports 0.5 kV (internal) / 1.0 kV (external) line to earth; AC power 1.0 kV line to line, 2.0 kV line to earth; not applicable to DC power ports	B
Conducted RF immunity	IEC 61000-4-6 (2004)	3 V, 0.15-80 MHz, 80 % AM at 1 kHz	A
Voltage dips and interruptions	IEC 61000-4-11 (2004)	Greater than 95 % for 0.5 cycle; 30 % for 30 cycles; greater than 95 % for 300 cycles	B for the first level, C for the other two

The act also carries resistibility tests on telecommunications and power ports, based on ITU-T K.21 and K.44 (section 8). A test plan written to EN 55032 and EN 55035 will cover much of this ground, but the levels, the frequency ranges and the criteria above are the ones the OCD checks.

The homologation code and the marking

Article 63 requires homologated products to carry the homologation identification as set by the operational procedure. That procedure is Ato 4088/2020.

The code

The código de homologação has twelve digits in the format HHHHH-AA-FFFFF (item 4.2): a five-character sequence identifying the homologation, two digits for the year in which the code was generated, and five characters identifying the manufacturer. Products homologated before Resolução 715/2019 took effect may keep the old code format, and units already on the market do not need remarking (item 9.6).

The four accepted formats

Format (item 5.5)	What it is	Condition
ANATEL seal	ANATEL logo plus homologation code, with or without the words "Agência Nacional de Telecomunicações"	Construction rules in section 8; minimum estimated heights 4 mm for the logo and 1 mm for the signature; colour optional
Text	"ANATEL HHHHH-AA-FFFFF" or "ANATEL: HHHHH-AA-FFFFF"	Same legibility rules
E-label	Electronic display of the identification	Only for devices with an integrated screen or working with one; no code or password; preferably within three steps of the main menu; survives a factory reset; packaging must also carry a physical format for consumer products (items 6.1 to 6.6)
QR Code	Code linking to product data	Must show at least the homologation code, model, lot, serial number, software version where applicable, factory and supplier; packaging must also carry a physical format (items 7.1 to 7.3)

The marking must be legible and indelible for the life of the product (item 5.4), on a non-removable part and in a place reachable without tools, except for an e-label (item 5.6). Ordinary paper or common adhesive tape is not an acceptable medium (item 8.2.1). Where a product demonstrably has no room, and carries no marks of foreign certifiers, the identification may move to the user manual and, optionally, the packaging (item 5.5.1). Each homologable item in a kit is marked separately (item 5.7).

Two rules matter for module integrators. A product that does not itself need homologation but contains a homologated one must state, in its manual, quick guide or one of the formats above, that it incorporates a product homologated by ANATEL under number HHHHH-AA-FFFFF, in the Portuguese wording set by item 9.1. And on suspension or cancellation, the holder must stop using the ANATEL mark, selling the product and advertising it (item 9.4).

Before entry into Brazil

Item 5.2.1 of Ato 4088/2020 requires imported products to be marked before they enter the country, except unfinished products completed in Brazil by the applicant, products that need a security seal, products for the importer's own use and certain medical products. Resolução 780/2025 repealed the equivalent sentence in the Regulation itself (former sole paragraph of article 63); item 5.2.1 of the operational procedure remained in the published text consulted on 7 October 2026. Products imported in bulk may carry a temporary label on the transport or protective packaging, with the definitive marking applied before sale (item 5.8).

Language

Ato 4088/2020 does not set a language rule for the label. The Portuguese requirement comes from consumer law: article 31 of the Consumer Defence Code (Lei 8.078/1990) requires the offer and presentation of products to give correct, clear, precise and conspicuous information in Portuguese about characteristics, warranty and origin, among others, and about health and safety risks. Article 95 of the Regulation, as amended in 2025, makes the consumer code apply on a subsidiary basis and lets ANATEL refuse or revoke a homologation where consumer or environmental obligations are not met.

Validity of the homologation, maintenance and renewal

A Brazilian homologation does not quietly expire on a date. Under Resolução 715/2019 the Certificado de Homologação carries no end date, but the Certificado de Conformidade that supports it has to be maintained on a fixed cycle for the homologation to keep producing effects.

The number does not expire, the certificate behind it does

Article 61: the Certificado de Homologação has no final term, unless the Requisito Técnico for the product type provides otherwise. The technical requirements for restricted-radiation radiocommunication equipment (Ato 14448/2017, as amended) set no such term, so for an ordinary radio product the homologation code is issued once and does not have to be renewed.

Article 62 attaches the condition that matters: a homologation granted on a Certificado de Conformidade is effective only while that certificate's periodic maintenance is regularly carried out. The certificate must state its own number, date of issue and date of validity (Ato 4083/2020, item 6.6.8.1 V). That validity date, held by the OCD, is what belongs in the compliance calendar.

Maintenance intervals are set product type by product type

The interval is written into the conformity assessment model that the Lista de Referência assigns to each product type, approved by Ato 7280/2020 and applicable 180 days after publication. On the certification route that model is a type test plus periodic evaluation of the product and of the factory management system. Article 46 lets a Requisito Técnico set its own maintenance conditions or periodicity.

Product type in the Lista de Referência	Assessment route	Periodic evaluation
All equipment covered by the restricted-radiation radiocommunication regulation, except restricted-radiation transceivers	Certification	Every 2 years
Restricted-radiation transceiver	Certification	Every 2 years
Mobile phone	Certification	Every 2 years
Access terminal station (ETA)	Certification	Every 2 years
Base-station transceiver, radio-frequency repeater, point-to-point antenna	Certification	Every 3 years
Product homologated for sale by Declaração de Conformidade com Relatório de Ensaios	Declaration	Every 3 years (Ato 3939/2021, item 7.1)

A maintenance round is not a fresh certification, but it is not a formality either. Ato 4083/2020 requires the OCD to place on file, as a minimum, a manufacturer declaration covering changes to the product and to the manufacturing process, updated photographs, the factory management system assessment where it applies, and a Relatório de Avaliação da Conformidade Técnica (items 6.8.3 and 6.8.4). Where laboratory testing applies, electrical safety tests must always be repeated, and any requirement found non-conforming in an earlier round has to be re-tested. The lab for maintenance tests is chosen with the same Ato 4091/2020 order (item 5.8).

Changes to the design, the manufacturing process or the software or firmware version must be reported to the OCD, or to ANATEL for a declaration-based homologation (article 49); the OCD assesses their impact (article 50).

What happens when a cycle is missed

Where periodic maintenance has not been carried out for more than 180 days, the OCD suspends the Certificado de Conformidade (article 52, V). If the non-conformities are not corrected, or no justification is accepted, within 180 days of that suspension, the certificate is cancelled (article 53). The OCD reports its decision, the file returns to the agency, and ANATEL may endorse the act and revoke the Certificado de Homologação (articles 54 and 73, V).

While the effect of the homologation certificate is suspended for want of maintenance, the maintenance deadline itself is suspended (article 68, second paragraph). Units already distributed by the holder before expiry, suspension or revocation may still be sold unless ANATEL orders a recall, and end users already using the product regularly may carry on (article 69). Homologations granted on a Declaração de Conformidade com Relatório de Ensaios are renewed on request for an equal period (article 75) and are revoked if renewal is not applied for in time (article 73, IX).

What changed in April 2020

Resolução 715/2019 was adopted on 23 October 2019, published in the Diário Oficial da União of 25 October 2019 and rectified on 7 January 2020. The Regulation took effect 180 days after publication, on 22 April 2020, the day Resolução 242/2000 and Resolução 323/2002 were repealed. Two provisions applied from publication: the market supervision programme and article 58, under which the homologation certificate is issued free of charge.

The earlier regime differed on two points. Maintenance followed the product category: Resolução 323/2002 required a maintenance round every 12 months for Category I (item 8.3.4) and every 24 months for Category II (item 8.4.4), with none for Category III. And the filing carried an ANATEL fee, set in Annex II of Resolução 242/2000: R$ 500 to homologate a Certificado de Conformidade, R$ 200 for a Declaração de Conformidade and R$ 200 to renew a homologation. Resolução 715/2019 repealed that annex outright. What remains is a two-year or three-year maintenance round, free as far as the agency is concerned but billed by the OCD and the laboratory.

What changed in 2024 to 2026

Date	Act	Change
10 March 2024	Ato 2436/2023 (as amended by Ato 7344/2023)	Minimum cybersecurity requirements become mandatory for consumer CPE: cable and xDSL modems, ONU/ONT, FWA and satellite routers, wireless routers and access points
14 October 2024	Ato 5155/2024	New technical requirements for mobile phone chargers become mandatory
13 August 2025	Ato 2105/2025	Updated requirements for access terminal stations (Ato 3151/2020) and mobile phones (Ato 3152/2020) become mandatory
4 August 2025	Resolução 780/2025 (DOU 4 August 2025)	Amends the Regulation: repeals article 20, second paragraph, and the sole paragraph of article 63; refurbished products only for public-policy programmes (article 90); consumer code applies on a subsidiary basis (article 95); adds a title on data centres
1 October 2025	Ato 14158/2025	Amends the restricted-radiation requirements of Ato 14448/2017 (new references and definitions, including vehicle radar, and revised out-of-band rules)
4 December 2025	Resolução 780/2025, articles 2 and 3	Four months after entry into force: marketplaces and digital platforms jointly liable with the seller, including for showing the homologation code in listings (article 55, second paragraph); new list of conducts subject to sanctions (article 83), including selling without the ANATEL seal and online ads without the code or with another product's code
3 March 2026	Acórdão 58/2026 of the ANATEL Board of Directors	Suspends the effects of the data-centre title added by Resolução 780/2025 pending review
25 May 2026	Ato 18086/2025	New import procedure in the federal foreign trade system (DUIMP declaration); prior homologation required for listed products, exceptions for test samples, temporary spectrum use and others; replaces Ato 4521/2021
6 October 2026	Ato 14158/2025 as amended by Ato 4746/2026	Article 11, item III, of Ato 14158/2025 becomes mandatory; products homologated before the mandatory date may keep the earlier equivalent requirements at maintenance
12 October 2027	Ato 5314/2026 as amended by Ato 10229/2026	Requirements for lithium secondary accumulators for stationary applications become mandatory

The cybersecurity layer predates these dates: Ato 77/2021 approved general cybersecurity requirements for products in the Lista de Referência that work as Internet-connected terminals or as network infrastructure. For an initial certification, the homologation request must include a declaration stating which of its requirements the product and supplier meet (item 1.2), and ANATEL may check that declaration through market supervision.

Brazilian frequency bands for short-range radio

Brazil is in ITU Region 2 with the United States, and the restricted-radiation rules of Ato 14448/2017 follow much of the FCC Part 15 logic. They are not a copy.

Band	EU (ETSI)	US (FCC)	Brazil (Ato 14448/2017)
Sub-GHz ISM	863-870 MHz SRD (EU 868 MHz)	902-928 MHz, Part 15.247	902-907.5 MHz and 915-928 MHz only; 907.5-915 MHz is not in the list
2.4 GHz	EN 300 328, up to 100 mW EIRP	Part 15.247, up to 1 W conducted	2400-2483.5 MHz, spread spectrum or OFDM only (item 10.1.1); up to 1 W peak output, 8 dBm per 3 kHz; output reduced above 6 dBi antenna gain except fixed point-to-point
5 GHz	EN 301 893, 5150-5350 and 5470-5725 MHz	Part 15 subpart E	5150-5350 MHz indoor only (item 11), 5470-5725 MHz; 5725-5850 MHz under item 10
6 GHz	5945-6425 MHz	5925-7125 MHz	5925-7125 MHz, opened by the 2021 amendments (Ato 1306/2021)

Two design consequences follow. An EU 868 MHz LPWAN radio has no home in that list, so a Brazil SKU needs a sub-GHz radio for 902-907.5 or 915-928 MHz. A US 915 MHz design is closer, but its channel plan must avoid 907.5-915 MHz. Cellular (3GPP technologies) is outside the restricted-radiation act and follows the mobile phone and access terminal requirements (Ato 3152/2020 and Ato 3151/2020, updated by Ato 2105/2025).

Step-by-step procedure

1. Freeze the product specification (hardware, firmware, antenna, accessories), since later changes have to be reported (article 49).
2. Set up the Brazilian applicant: a Brazilian legal entity or resident (article 20), which will also mark and import the product.
3. Choose an OCD from the ANATEL list. It classifies the product in the Lista de Referência and tells you which requirements apply and must be tested (Ato 4083/2020, items 6.2.1 and 6.2.3).
4. Map the requirements: the product-specific Requisito Técnico, Ato 1120/2018 for EMC where it applies, Ato 14448/2017 for short-range radio, the cybersecurity declaration of Ato 77/2021 and, for CPE, Ato 2436/2023.
5. Choose the laboratory in the Ato 4091/2020 order, and document any reason for going down it.
6. Import samples for testing; samples for conformity assessment are an exception to prior homologation at import, in a quantity consistent with the tests (Ato 18086/2025, items 5.1.1 and 8.1).
7. Test, then let the OCD review the reports and the documents. Management-system documents in a foreign language need a sworn translation (Ato 4083/2020, item 6.4.2.2).
8. Receive the Certificado de Conformidade, file the homologation request in the ANATEL system (article 57) and answer any request within the deadline (article 59).
9. Mark the product in one of the Ato 4088/2020 formats, before entry into Brazil where item 5.2.1 applies, and show the homologation code in every online listing.
10. Import for sale with the code in the import declaration (Ato 18086/2025, item 6.4).
11. Keep the certificate alive: maintenance every 2 or 3 years, change notifications, and adaptation when a Requisito Técnico changes (article 28).

ANATEL, FCC and CE, what is not transferable

Criterion	CE (RED)	FCC (Part 15)	ANATEL (Brazil)
Who applies	Manufacturer, with an authorised representative optional under RED	Grant applicant, with a US agent for service of process	Brazilian resident or Brazilian legal entity (article 20)
Third party	Notified Body only for some RED modules	TCB	OCD on the certification route (article 36)
Laboratory	Manufacturer choice	FCC-recognised lab	ANATEL-habilitated lab, Ato 4091/2020 order
EMC reference	Harmonised standards (EN 55032, EN 55035)	Part 15 subpart B	Ato 1120/2018 (CISPR 22 / CISPR 24 basis)
Identifier on product	CE mark	FCC ID	Twelve-digit homologation code, four formats
Validity	No certificate expiry	Grant does not expire	Homologation without term, but maintenance every 2 or 3 years
Online listings	No code requirement	No code requirement	Homologation code required in online ads (article 83, VIII)

A product certified to CE and FCC must be treated, for Brazil, as not yet homologated. The existing reports help prepare the test plan and may be reused only through the foreign-lab route of Ato 4091/2020. See CE vs FCC for the EU and US comparison.

Sustainability and environment, related requirements

Article 95 of the Regulation states that complying with it does not exempt anyone from other national obligations, notably consumer and environmental ones, and that ANATEL may refuse or revoke a homologation where they are not met. The main environmental text for electronics is the Política Nacional de Resíduos Sólidos (Lei 12.305/2010): its article 33 obliges manufacturers, importers, distributors and retailers of batteries (item II) and of electrical and electronic products and their components (item VI) to set up reverse logistics (logística reversa) systems. These obligations fall under other authorities, but they apply to the same product. For the EU-side equivalent, see the EU Battery Regulation.

Claims the texts contradict

Common claim (some of it on this page before)	What the texts say
"OCDs are accredited by ANATEL."	ANATEL designates OCDs (article 7); accreditation is by Inmetro, or recognition of a foreign body through a mutual recognition agreement (article 8).
"Brazil has partial MRAs with the US and Mexico, so some foreign reports are accepted."	The texts reviewed name no such agreement. What they provide is the Ato 4091/2020 route: foreign ILAC-accredited labs third in order, with a documented justification, and only where their scope matches the ANATEL requirements.
"The number must appear next to the ANATEL logo."	Ato 4088/2020 accepts four formats, including the plain text "ANATEL HHHHH-AA-FFFFF", an e-label and a QR Code; the logo is only one of them.
"Portuguese must be at least as visible as other languages on the label."	No such rule appears in Ato 4088/2020. The Portuguese duty comes from article 31 of the Consumer Defence Code, which covers information on the offer and presentation of the product.
"If the local representative stops, the homologation is suspended."	Article 73, item VIII, makes withdrawal of the commercial representation by the foreign manufacturer a ground for revocation.
"Several brands can share one homologation number if the hardware is identical."	Homologation rights can be assigned or shared (article 20, third paragraph), but an assignment takes effect only once ANATEL issues a certificate in the name of the new holder (article 66).
"The Category I, II, III scheme is gone from every ANATEL text."	It is gone from the Regulation, but Ato 1120/2018, kept in force by article 93, still scopes its EMC immunity tests by Category I and II.
"Brazil opens 902-928 MHz like the US."	Ato 14448/2017 lists 902-907.5 MHz and 915-928 MHz; 907.5-915 MHz is not included.
"ANATEL homologation has to be renewed every year."	Article 61: no final term by default. The recurring obligation is the 2-year or 3-year maintenance of the Certificado de Conformidade; the annual cycle belonged to Category I under the repealed Resolução 323/2002.
"Only the seller is liable for products sold online without homologation."	Since 4 December 2025, marketplaces and digital platforms are jointly liable with the seller, including for showing the homologation code in listings (article 55, second paragraph).

Common pitfalls

Pitfall	Consequence
Assuming a CE or FCC report will be accepted as is	The OCD needs a habilitated lab in the Ato 4091/2020 order; a foreign report without a matching accredited scope is not usable
Reading the product route off the repealed categories	Wrong conformity assessment model; the Lista de Referência decides
No Brazilian applicant or legal representative lined up	No homologation request is possible, and no import for sale
Keeping an EU 868 MHz LPWAN radio, or a 902-928 MHz channel plan, for Brazil	Operation outside the bands of Ato 14448/2017
Testing EMC only to EN 55032 and EN 55035	Gaps against the Ato 1120/2018 levels, ranges and resistibility tests
Online listings without the homologation code	Conduct subject to sanctions under article 83, VIII, since 4 December 2025, for seller and platform
Changing radio firmware after homologation without telling the OCD	Breach of article 49; the OCD has to assess the change
Letting the maintenance date slip	Suspension after 180 days, cancellation 180 days later, possible revocation
Host product sold without the statement that it incorporates a homologated module	Missing the marking required by Ato 4088/2020, item 9.1
Treating ANATEL as the only Brazilian obligation	Consumer and environmental duties also apply, and article 95 lets ANATEL act on them
