What is the minimum CE marking size and what can justify going below it?

Annex II of Regulation (EC) No 765/2008 sets 5 mm "where specific legislation does not impose specific dimensions", and the drawing must keep its proportions when resized. Annex II itself has no small-product waiver. The waiver comes from the sector text: Article 19(2) of the RED (Directive 2014/53/EU) allows radio equipment to carry a CE marking lower than 5 mm provided it remains visible and legible. Under the LVD and the EMC Directive there is no such waiver: if the marking cannot go on the product, it goes on the packaging and the accompanying documents. The RED also requires the CE marking on the packaging in every case (Article 20(1)).

Must the notified body number always appear next to the CE marking?

No. Article R12(3) of Decision No 768/2008/EC requires it only where the notified body is involved in the production control phase. In the modules of Annex II to that Decision this covers A1, A2, C1 and C2 when a notified body does the checks, and D, D1, E, E1, F, F1, G, H and H1. A body that only did the EU-type examination (module B) does not put its number after the marking. Under the RED the number appears only when Annex IV (full quality assurance) is used, and it must have the same height as the CE marking (Article 20(3)).

What exactly must an FCC label show?

Under 47 CFR 2.925(a)(1), the FCC ID, preceded by the words "FCC ID" in capital letters on a single line, legible without magnification. The FCC ID is the Grantee Code (three characters for older codes, five since 1 May 2013) followed by a product code of up to 14 characters (2.926). Part 15 devices also carry the compliance statement of 15.19(a)(3). The name and address of a US responsible party are not a label item: 2.1077 requires them in a compliance information statement supplied with products authorised under Supplier's Declaration of Conformity (SDoC). The type size need not exceed eight-point (2.925(f)).

Which marks must carry a number or a second element to be valid?

Each text says something different. The CE marking takes a notified body number only when a body is in production control. The FCC label needs the FCC ID on one line. ISED requires the certification number and the HVIN on the label. Korea requires the KC mark, the model name and the identifier (R-C, R-R or R-I prefix, or a management number for self-confirmed equipment). ANATEL accepts four formats, all built on the twelve-digit homologation code. Mexico requires "IFT" plus the certificate number and the IFT seal. The CCC rules, the Giteki form and the EAC decision fix the shape and size of the mark itself; the RCM carries no number at all.

How can one product be labelled for ten markets without multiplying part numbers?

Three layouts are used: a single label with every mark, regional label variants, or a reduced physical label backed by e-labelling where the texts allow it. E-labelling is a legal route for the FCC (47 CFR 2.935), ISED (RSS-Gen Annex B), Australia, Japan (certification ordinance Article 8), Korea (RRA Notice 2026-4, Annex 5), Taiwan (Article 18 of the NCC rules), Brazil (Ato 4088/2020), China for CMIIT and, on an integrated screen, CCC. It is not a route for the CE marking: the Blue Guide 2022 states that electronic labelling only is not allowed.

Is there a rule on the spacing between two marks on the same label?

None of the texts read for this page sets a distance between two regulatory marks. What they fix is the form, a minimum size where they have one, legibility and durability. The often-quoted "one mark height of white space" or "4.5:1 contrast" rules are design conventions, not legal requirements; the Blue Guide accepts any colour or a hollow CE marking as long as it stays visible and legible.

Does the WEEE symbol follow the same rules as the CE marking?

No. The crossed-out wheeled bin comes from Article 14(4) and Annex IX of Directive 2012/19/EU, preferably drawn to EN 50419:2022. It is required whatever conformity route the product followed, carries no notified body number, and moves to the packaging, the instructions for use and the warranty only where size or function of the product make that necessary. Article 15(2) adds a mark showing the product was placed on the market after 13 August 2005: a bar under the bin or a date.

Do industry marks (Bluetooth, Wi-Fi CERTIFIED, USB, HDMI) follow regulatory rules?

No. They are trade marks licensed by private bodies under contract. Bluetooth SIG ties the Bluetooth trade mark licence to qualification; the Wi-Fi Alliance reserves the Wi-Fi CERTIFIED logo and certification marks to members whose products are certified, while the words Wi-Fi and Wi-Fi 4 to Wi-Fi 7 are free to use to describe products; USB-IF and HDMI Licensing Administrator license their logos the same way. None of them replaces a regulatory marking, and no public text sets their size.

Multi-marking layouts: CE, FCC, UKCA, ANATEL and other marks

Hugues Orgitello updated 7 Oct 2026 21 min read

The label of an electronic product sold in several markets is rarely the first topic a project thinks of, and it tends to become critical at industrialisation. Each jurisdiction has its own mark, its own size rule (or none), its own list of things that must sit next to the mark, and its own answer on e-labelling. This page reads those rules from the texts themselves, jurisdiction by jurisdiction (CE, UKCA, FCC, ISED, RCM, PSE, Giteki, KC, NCC, ANATEL, CMIIT, CCC, EAC, Mexico, Saudi Arabia, Egypt, South Africa), then covers environmental symbols, industry logos, e-labels, a placeholder layout for a global IoT product, and the claims about marking that the texts contradict, including several this page used to make.

Why the marking stack becomes an industrialisation topic

A product for the European market alone carries the CE marking (with a notified body number only in the cases described below), the WEEE symbol, a type, batch or serial number, and the name and postal address of the manufacturer and, for imported products, of the importer (RED Articles 10(6), 10(7) and 12(3)). The same product sold in the EU, Great Britain, the United States, Canada, Brazil, Japan, Korea, Taiwan, China and Australia adds a distinct regulatory mark or identifier per market, plus industry logos if the product claims Bluetooth, Wi-Fi CERTIFIED or USB, plus the battery symbols and, from 18 February 2027, a battery QR code. The usable surface does not grow with the list.

Two decisions follow from the product specification phase. The first is the labelling strategy (single worldwide label, regional variants, or e-label where allowed), which drives the number of label references and the risk of shipping the wrong one. The second is the marking technology (printed label, pad printing, laser engraving, moulding), which decides what can be made legible at the smallest sizes that the texts allow: an FCC ID of up to 19 characters, a Korean identifier built from applicant and equipment codes, or a twelve-digit ANATEL code do not shrink the way a logo does.

Which element must sit next to which mark

Some marks are only complete with a second element. Others are complete on their own, and adding a number the text does not ask for is itself an error.

Mark	Element required with it	When	Text
CE	Notified body identification number	Body involved in production control: A1, A2, C1, C2 (when a body does the checks), D, D1, E, E1, F, F1, G, H, H1. RED: Annex IV only	768/2008 R12(3) and Annex II; RED Art. 20(3)
CE	Nothing	Module A, or module B followed by C	Blue Guide 2022, 4.5.1
UKNI	CE marking	Always	GOV.UK Northern Ireland guidance
FCC ID	The words "FCC ID" on the same line	Always	2.925(a)(1)
FCC host product	"Contains FCC ID:" plus the module FCC ID	Module label not visible once installed	15.212(a)(1)(vi)
ISED number	HVIN on the label	Always	RSS-Gen 9.4
ISED host product	"Contains IC:" plus the module number, and the HMN	Module number not visible	RSS-Gen 9.4.4.2
KC mark	Model name and identifier	Always (small-surface relief at 400 mm²)	RRA Notice 2026-4, Annex 5
Giteki logo	Symbol R and certification number	Always	Form No. 7
PSE diamond	Supplier name and inspection body name	Specified electrical products	Art. 17(1)(i)
NCC label	Model on the body, NCC emblem on the packaging	Always	NCC rules Art. 18
ANATEL seal	Homologation code	When the seal format is used (the code alone is another accepted format)	Ato 4088/2020
IFT	Certificate number and IFT seal	Always	Guideline 38
ICASA logo	Certificate number TA XXXX-YYYY	Always	Labelling Regulations, 2013
WEEE bin	Placed-after-2005 indicator (bar or date) and producer identification	Always	Directive 2012/19/EU Art. 15(2)
RCM	Nothing	The RCM carries no number	Equipment Rules 2021
CCC	Nothing in the marking rules	The 2024 requirements fix shape, sizes and placement only	CCC Mark Management Requirements

A CE marking without the required NB number, or with a number that should not be there, is a formal non-compliance under Article R34(1)(a) of Decision 768/2008 (conformity marking "affixed in violation of Article [R11] or of Article [R12]"), which the authority orders the operator to end.

Spacing, contrast and orientation

No text read for this page sets a spacing between two regulatory marks or a contrast ratio. What the texts fix is form, minimum size where one exists, legibility and durability. The EAC decision asks for a single colour contrasting with the surface; the Blue Guide accepts any colour or a hollow CE marking if it stays visible and legible. Spacing and orientation are therefore design choices: the practical test is that a surveillance officer can read each mark and attach each number to the right mark without ambiguity.

Durability: what each text says about the medium

The choice of technology must meet the durability wording of every target market at once.

Text	Durability wording
CE (768/2008 R12(1), Blue Guide 4.5.1)	Visibly, legibly and indelibly; not removable under normal circumstances without noticeable traces. The marking need not be an integral part of the product
FCC (2.925(d))	Etched, engraved, stamped, indelibly printed, or a permanently attached nameplate; visible from outside
RCM (Equipment Rules, Schedule 3, clause 5)	Durable, and permanent or hard to remove
ANATEL (Ato 4088/2020, items 5.4 and 8.2.1)	Legible and indelible for the life of the product; ordinary paper or common adhesive tape not acceptable
ICASA (Labelling Regulations, 2013)	Permanently affixed to the equipment
CCC (2024 requirements)	Standard stickers: clear, complete, rub-resistant, firmly attached; printed or moulded marks inseparable from the body or nameplate
EAC (Decision No. 711)	Any method giving a clear image for the whole service life
Giteki (Form No. 7)	A material not easily damaged; any colour if easy to identify

Laser engraving and moulding meet all of these at once; a printed paper label does not meet the ANATEL wording.

Industry marks: a contractual regime

Industry marks are trade marks licensed by private bodies. Their rules come from the licence contract, not from product law, and no public text sets their size.

Mark	Licensor	What gives the right to use it
Bluetooth word mark and logos	Bluetooth SIG	Membership and completion of the Bluetooth Qualification Process, which brings the product under the patent/copyright and trademark licence agreements
Wi-Fi CERTIFIED logo and certification marks	Wi-Fi Alliance	Membership and certification. The words Wi-Fi and Wi-Fi 4 to Wi-Fi 7 are brands for public use, licence free, to describe products
USB logos	USB-IF	Certification and a trademark licence (membership or the Non-Member Logo License Agreement)
HDMI logo	HDMI Licensing Administrator, Inc.	Adopter Agreement and compliance testing
Matter certified product logo	Connectivity Standards Alliance	Matter certification
ENERGY STAR	US DOE (lead agency since June 1, 2026) with EPA	Certification by an EPA-recognised certification body. EPA agreements exist with Canada, Switzerland and Japan; the EU agreement expired on February 20, 2018
PTCRB	PTCRB, administered by CTIA Certification	An operator certification for cellular devices on North American networks, not a consumer logo on the label

These marks never replace regulatory marks: a Bluetooth product carries the Bluetooth logo (contract) and the CE marking and the FCC ID and the ISED number. See Bluetooth SIG Qualification, Wi-Fi Alliance, Thread Group, USB-IF, HDMI, Matter, ENERGY STAR and PTCRB.

Environmental symbols, product passports and new EU markings

Marking	Who	From	Text
WEEE crossed-out wheeled bin, preferably to EN 50419:2022, with the post-2005 bar or a date	All EEE in scope	Applies	Directive 2012/19/EU Art. 14(4), 15(2), Annex IX
Battery separate collection symbol, at least 3% of the largest side (maximum 5 × 5 cm), Cd or Pb symbol below it where thresholds are exceeded	All batteries	18 August 2025	Regulation (EU) 2023/1542 Art. 13(3) and (4)
Battery general label (Annex VI Part A)	All batteries	18 August 2026 or 18 months after the labelling implementing act, whichever is later	2023/1542 Art. 13(1)
Battery QR code	All batteries	18 February 2027	2023/1542 Art. 13(6)
Battery passport, reached through the QR code	LMT, EV and industrial batteries above 2 kWh	18 February 2027	2023/1542 Art. 77
Charger pictogram (charger included or not) and charging power sentence	Radio equipment in the common charger categories	28 December 2024; laptops 28 April 2026	Directive (EU) 2022/2380, RED Art. 3a and Annex Ia
EU energy label with repairability class	Smartphones and slate tablets	20 June 2025	Delegated Regulation (EU) 2023/1669
Digital product passport data carrier	Product groups covered by an ESPR delegated act	Per delegated act	Regulation (EU) 2024/1781 Art. 9 and 10

Under Article 10(1)(b) of ESPR, the delegated act decides whether the data carrier of the Digital Product Passport (DPP) sits on the product, its packaging or the accompanying documentation, and Article 9(2)(d) lets it choose model, batch or item level. Battery labels and the QR code go on the battery itself, or on the packaging and documents only where the size or nature of the battery makes that impossible (Article 13(7)). See WEEE, EU Battery Regulation, ESPR and the DPP.

E-label: which texts allow it

Jurisdiction	E-label allowed?	Condition	Physical element still required
EU (CE)	No	Blue Guide 2022: electronic labelling only is not allowed	CE marking on the product or data plate, and on the packaging under the RED
Great Britain (UKCA)	No provision	Label or accompanying document allowed until 31 December 2027	UKCA or CE
US (FCC)	Yes, 47 CFR 2.935	Integrated display, or device that only works with one; no more than three steps from the settings menu	FCC ID or other identification on the device or packaging at import and sale
Canada (ISED)	Yes, RSS-Gen Annex B	No more than three steps from the main menu, no special codes or accessories	Physical label on the packaging
Australia (RCM)	Yes	Built-in display that can always show the RCM; QR code linking to a page displaying the RCM	None stated for the e-label
Japan (Giteki)	Yes, Article 8	Display on the equipment or on a product connected by wire before first use	Document explaining that the mark is electronic and how to display it
Korea (KC)	Yes, Annex 5	Non-removable display or QR code, no more than three menu steps	KC mark and model name on the equipment or packaging
Taiwan (NCC)	Yes, Article 18	Device with a built-in screen or that needs one to operate	Operating instructions on the box, manual or leaflet
Brazil (ANATEL)	Yes, Ato 4088/2020	Integrated screen; no code or password; survives a factory reset	Physical format on the packaging of consumer products
China (CMIIT)	Yes, Order 57 Art. 15	Code shown electronically	Not set in Article 15
China (CCC)	Yes, since January 1, 2024	Integrated screen and electronic nameplate; the manual gives the path	Standard or printed CCC mark on the smallest sales package
South Africa (ICASA)	On written request	Integral display	Packaging label

The FCC route rests on the E-LABEL Act of November 26, 2014 and on 2.935, adopted on November 2, 2017; earlier FCC guidance on electronic labelling was published in KDB 784748. E-labelling moves the compliance risk into the firmware: a menu change or an update that removes the regulatory screen breaks the label. See E-label vs physical label.

Placeholder layout for a compact global IoT product

The layout below shows the elements a cellular and BLE product sold in the EU, Great Britain, the US, Canada, Australia, Brazil, Japan, Korea, Taiwan and China would place on a physical label. All values are placeholders, not real numbers.

+================================================+

Packaging carries more: the CE marking again (RED Article 20(1)), the NCC emblem, the ANATEL physical format where an e-label is used, the charger pictogram and, for Korea, whatever Annex 5 lets you move off a small product. Where the product has a screen, the FCC, ISED, Giteki, KC, NCC, ANATEL, CMIIT and CCC elements can move to an e-label within each condition above; the CE and UKCA markings, the WEEE bin and the battery symbols cannot.

Three layout models

Model 1, single worldwide label

One label with all marks for all markets. One label reference and no risk of shipping the wrong variant, but the most crowded surface and a redesign at each market addition. Suits low-volume products sold everywhere at once (industrial equipment, OEM modules).

Model 2, regional label variants

One label per zone (EU and UK, North America, Latin America, Asia-Pacific). More room per mark and markets can be added inside a zone without touching the others, at the cost of more references and the risk of a wrong label reaching the wrong market.

Model 3, reduced physical label with e-label

A physical label with the marks that must stay physical (CE, UKCA where used, WEEE, battery symbols, EAC, ICASA, and the packaging elements listed above) and e-labels for the rest where the texts allow. Compact, and a market can be added by firmware, but only for products with a screen and with a firmware review in the label process.

Cybersecurity marking

The EU Cyber Resilience Act (Regulation (EU) 2024/2847) uses the CE marking (Article 30) and adds an information duty rather than a new logo: the end date of the support period, at least month and year, must be shown at the time of purchase (Article 13(19)). Its obligations apply in full from 11 December 2027, with reporting duties from 11 September 2026.

In the US, 47 CFR 8.203(f) defines the FCC IoT label as the Cyber Trust Mark plus a QR code leading to a registry. As of the FCC public notice DA 26-834 of 11 August 2026, no Cybersecurity Label Administrator could yet grant authorisation to use the label; UL Solutions withdrew as Lead Administrator effective 19 December 2025 and ioXt Alliance was selected on 13 April 2026. See NIST IR 8425 and the Cyber Trust Mark and EN 303 645.

Languages on the label and in the box

The language rules attach mostly to instructions and warnings, not to the marks. Under RED Article 10(8), instructions and safety information must be in a language easily understood by end users, as determined by the Member State, and the manufacturer contact details in a language easily understood by end users and authorities (Article 10(7)). Taiwan requires Traditional Chinese warnings where the technical rules call for them (Article 18). Saudi Arabia requires labelling data in Arabic, with Arabic prevailing. Brazil takes its Portuguese requirement from the Consumer Defence Code, not from Ato 4088/2020. Korea requires a Korean user manual in the certification file; the texts read for the KC guide do not require the label itself to be in Korean. A multilingual paper leaflet next to a compact label of marks is the usual way to meet all of this without crowding the label.

Claims the texts contradict

Common claim (including earlier versions of this page)	What the texts say
"The minimum 5 mm CE height comes from Decision 768/2008, which allows a derogation for small products"	The 5 mm and the drawing are in Annex II of Regulation 765/2008, which has no small-product clause. RED Article 19(2) is the waiver for radio equipment; the LVD and EMC Directive have none
"The notified body number appears for modules D, E, F, G or H"	Decision 768/2008 also provides it in A1, A2, C1 and C2 when a body does the checks, and in D1, E1, F1 and H1. Under the RED, only Annex IV
"The FCC ID must be accompanied by the name and address of the US responsible party under 2.1077"	2.1077 is the compliance information statement for SDoC products, supplied with the product, not a label item
"The FCC has allowed e-labels since 2014, ISED since 2017"	The E-LABEL Act dates from November 26, 2014; the rule 2.935 was adopted on November 2, 2017. ISED rules are now in RSS-Gen issue 6, Annex B
"The Korean label shows the KCC number (radio) or KC Safety ID"	RRA Notice 2026-4 uses identifiers with R-C, R-R or R-I prefixes, or a management number for self-confirmation
"EAC: 5 mm typical height, TR CU 020/2011 rule"	Customs Union Commission Decision No. 711 sets a base size of at least 5 mm and leaves the actual size to the manufacturer
"CCC sizes are S, M, L, and the certificate number must sit next to the mark"	The 2024 requirements define five standard sizes from 8 × 6.3 mm to 60 × 47 mm and scalable printed marks; they do not require a certificate number on the mark
"The ANATEL logo is inseparable from the homologation number"	Ato 4088/2020 accepts four formats, including the word ANATEL plus the code, an e-label and a QR code
"The RCM carries a supplier identifier, 3 mm typical"	The RCM carries no number; 3 mm is the minimum in Schedule 3, clause 5(5)
"NCC labelling follows LP0002"	The labelling duties are in Article 18 of the 2020 NCC rules; LP0002 is a technical specification for low-power devices
"Wi-Fi certification grants the right to use the Wi-Fi Certified mention"	It grants the Wi-Fi CERTIFIED logo and certification marks; the words Wi-Fi and Wi-Fi 4 to Wi-Fi 7 are free to use
"Energy Star is run by EPA and DOE with EU partners"	The EU agreement expired on February 20, 2018; DOE is the lead agency since June 1, 2026
"'China Export' is a distorted CE found when the official vector file is not used"	In its answer to P-5938/2007 the Commission knew of no China Export mark and read it as a CE marking that does not respect the prescribed dimensions and proportions

"Industry practice: one mark height of white space and a 4.5:1 contrast"	No text sets a spacing or a contrast ratio; the Blue Guide accepts any colour or a hollow marking if legible
"The German WEEE registration number belongs on the product label"	Annex IX and Article 15(2) of Directive 2012/19/EU require the bin, the post-2005 indicator and producer identification; they do not require a national registration number on the product
"The US Cyber Trust Mark rollout began in 2024"	The rules were adopted in 2024, but no administrator could yet grant the label as of 11 August 2026 (DA 26-834)

Recurring marking errors

A notified body number after a B + C CE marking, which tells the authority that a body checks production when none does.
A CE marking typed in a font or stretched, which departs from the proportions of Annex II; this is what the Commission called the "China Export" case.
CE moved to the packaging for design reasons: the Blue Guide excludes purely aesthetic grounds.
Radio equipment without CE on the packaging, which RED Article 20(1) requires in every case.
SDoC compliance information missing from the box, or put on the label of a certified product where it is not required.
An ANATEL code on paper or common adhesive tape, which item 8.2.1 of Ato 4088/2020 rejects.
UKNI used alone, or UKCA used for Northern Ireland.
A Bluetooth or Wi-Fi CERTIFIED logo without the licence behind it, a contractual breach separate from regulatory marking.
An identifier at the legibility limit of the chosen technology, which fails the "legible without magnification" wording of 2.925 even if it is technically present.
An e-label with no physical element where the text requires one (packaging label for ISED, physical format on the packaging for ANATEL, sales package mark for CCC).

Multi-jurisdiction label review workflow

Jurisdiction pass: market by market, check that each mandatory mark is present with its required element, and that no element is added that the text does not require.
Geometry pass: on the final printed sample, check form, proportions and the minimum sizes that exist (CE and UKCA 5 mm, RCM 3 mm, Giteki 5 mm or 3 mm, EAC 5 mm, CCC standard sizes, ICASA 3 × 3 mm).
Durability pass: check the technology against the strictest durability wording among target markets.
Document pass: declarations of conformity, SDoC compliance information, manuals and packaging carry the matching information (importers, manufacturer address, charger pictogram).
E-label pass, if used: each screen shows the required content within the access limit of each text, and the required physical element exists on the product or packaging.

Key takeaways

Each mark has its own text, size rule and fallback; no text sets spacing or contrast between marks.
The CE notified body number depends on the module (under the RED, Annex IV only); the RCM and the CCC mark carry no number.
The US responsible party belongs in the SDoC compliance information, not on the FCC label.
E-labelling is a legal route in the US, Canada, Australia, Japan, Korea, Taiwan, Brazil and China, never for the CE marking.
New EU markings arrive on fixed dates: battery collection symbol (18 August 2025), charger pictogram (28 December 2024, laptops 28 April 2026), battery QR code (18 February 2027).
Industry logos are licences: they add marks, never replace regulatory ones.

Frequently asked questions

What is the minimum CE marking size and what can justify going below it?: Annex II of Regulation (EC) No 765/2008 sets 5 mm "where specific legislation does not impose specific dimensions", and the drawing must keep its proportions when resized. Annex II itself has no small-product waiver. The waiver comes from the sector text: Article 19(2) of the RED (Directive 2014/53/EU) allows radio equipment to carry a CE marking lower than 5 mm provided it remains visible and legible. Under the LVD and the EMC Directive there is no such waiver: if the marking cannot go on the product, it goes on the packaging and the accompanying documents. The RED also requires the CE marking on the packaging in every case (Article 20(1)).
Must the notified body number always appear next to the CE marking?: No. Article R12(3) of Decision No 768/2008/EC requires it only where the notified body is involved in the production control phase. In the modules of Annex II to that Decision this covers A1, A2, C1 and C2 when a notified body does the checks, and D, D1, E, E1, F, F1, G, H and H1. A body that only did the EU-type examination (module B) does not put its number after the marking. Under the RED the number appears only when Annex IV (full quality assurance) is used, and it must have the same height as the CE marking (Article 20(3)).
What exactly must an FCC label show?: Under 47 CFR 2.925(a)(1), the FCC ID, preceded by the words "FCC ID" in capital letters on a single line, legible without magnification. The FCC ID is the Grantee Code (three characters for older codes, five since 1 May 2013) followed by a product code of up to 14 characters (2.926). Part 15 devices also carry the compliance statement of 15.19(a)(3). The name and address of a US responsible party are not a label item: 2.1077 requires them in a compliance information statement supplied with products authorised under Supplier's Declaration of Conformity (SDoC). The type size need not exceed eight-point (2.925(f)).
Which marks must carry a number or a second element to be valid?: Each text says something different. The CE marking takes a notified body number only when a body is in production control. The FCC label needs the FCC ID on one line. ISED requires the certification number and the HVIN on the label. Korea requires the KC mark, the model name and the identifier (R-C, R-R or R-I prefix, or a management number for self-confirmed equipment). ANATEL accepts four formats, all built on the twelve-digit homologation code. Mexico requires "IFT" plus the certificate number and the IFT seal. The CCC rules, the Giteki form and the EAC decision fix the shape and size of the mark itself; the RCM carries no number at all.
How can one product be labelled for ten markets without multiplying part numbers?: Three layouts are used: a single label with every mark, regional label variants, or a reduced physical label backed by e-labelling where the texts allow it. E-labelling is a legal route for the FCC (47 CFR 2.935), ISED (RSS-Gen Annex B), Australia, Japan (certification ordinance Article 8), Korea (RRA Notice 2026-4, Annex 5), Taiwan (Article 18 of the NCC rules), Brazil (Ato 4088/2020), China for CMIIT and, on an integrated screen, CCC. It is not a route for the CE marking: the Blue Guide 2022 states that electronic labelling only is not allowed.
Is there a rule on the spacing between two marks on the same label?: None of the texts read for this page sets a distance between two regulatory marks. What they fix is the form, a minimum size where they have one, legibility and durability. The often-quoted "one mark height of white space" or "4.5:1 contrast" rules are design conventions, not legal requirements; the Blue Guide accepts any colour or a hollow CE marking as long as it stays visible and legible.
Does the WEEE symbol follow the same rules as the CE marking?: No. The crossed-out wheeled bin comes from Article 14(4) and Annex IX of Directive 2012/19/EU, preferably drawn to EN 50419:2022. It is required whatever conformity route the product followed, carries no notified body number, and moves to the packaging, the instructions for use and the warranty only where size or function of the product make that necessary. Article 15(2) adds a mark showing the product was placed on the market after 13 August 2005: a bar under the bin or a date.
Do industry marks (Bluetooth, Wi-Fi CERTIFIED, USB, HDMI) follow regulatory rules?: No. They are trade marks licensed by private bodies under contract. Bluetooth SIG ties the Bluetooth trade mark licence to qualification; the Wi-Fi Alliance reserves the Wi-Fi CERTIFIED logo and certification marks to members whose products are certified, while the words Wi-Fi and Wi-Fi 4 to Wi-Fi 7 are free to use to describe products; USB-IF and HDMI Licensing Administrator license their logos the same way. None of them replaces a regulatory marking, and no public text sets their size.
