PTCRB · Pillar

Eighteen concrete questions on PTCRB certification, organised in six themes: scope and operators, modules and end-products, IMEI and identifiers, costs and timing, FCC/GCF comparisons, post-market.

Scope and operators

Section titled “Scope and operators”

What's the difference between PTCRB and FCC?

Section titled “What's the difference between PTCRB and FCC?”

FCC certifies compliance with US radio emission limits (47 CFR, government regulation). PTCRB certifies compliance with North American cellular operator network requirements (private operator program). Both are distinct and both required to sell cellular equipment in the US and Canada.

Who are the operators behind PTCRB?

Section titled “Who are the operators behind PTCRB?”

Main North American operators, AT&T, T-Mobile, Verizon (USA), Bell, Rogers, Telus (Canada), plus FirstNet, Starlink and regional operators (16 listed on ptcrb.com in 2026). The program is administered by CTIA Certification. Verizon also runs its own Open Development device certification on top of PTCRB.

Must my cellular product mandatorily pass PTCRB?

Section titled “Must my cellular product mandatorily pass PTCRB?”

Yes if it is intended for member operator networks. Without PTCRB certification, the product cannot be homologated on these networks, which amounts to commercial market access impossibility.

Modules and end-products

Section titled “Modules and end-products”

What's the difference between module certification and device certification?

Section titled “What's the difference between module certification and device certification?”

Module certification certifies a cellular module (integrable RF card) that can then be reused by integrators. The final product built on a certified module passes a reduced device-level certification, IoT Network Certified for IoT devices, a fraction of the cost and timing of complete module certification.

My Quectel/u-blox/Sierra module is already PTCRB-certified, what does that change?

Section titled “My Quectel/u-blox/Sierra module is already PTCRB-certified, what does that change?”

You benefit from the module manufacturer's certification. Your product passes a reduced device-level certification (IoT Network Certified for IoT devices), essentially radiated tests (OTA) in final configuration plus integration verification. Cost and timing are a fraction of a full module campaign.

What happens for 2G/3G sunsets?

Section titled “What happens for 2G/3G sunsets?”
  • 3G UMTS: sunset completed on AT&T US (February 2022) and T-Mobile US (July 2022).
  • 2G GSM: AT&T retired 2G in 2017; remaining North American 2G/3G networks are being phased out.
  • Legacy GSM test cases have been retired from current PTCRB requirements.

For long-duration IoT products, switch to Cat-M or NB-IoT, whose operator roadmaps extend well into the 2030s.

IMEI and identifiers

Section titled “IMEI and identifiers”

What is an IMEI TAC?

Section titled “What is an IMEI TAC?”

Type Allocation Code: the 8-digit identifier of the certified model, first part of the IMEI. For PTCRB devices it is issued by CTIA Certification, acting as IMEI Administrator and GSMA Reporting Body. One TAC allows 1 million unique IMEIs; additional TACs are allocated for high-volume products.

How is an IMEI composed?

Section titled “How is an IMEI composed?”
TAC (8) + Serial Number (6) + Check Digit (1) = 15 digits
Example: 35123456 123456 7

The Check Digit is calculated by the Luhn formula on the first 14 digits.

What happens with IMEI duplicates?

Section titled “What happens with IMEI duplicates?”

Operators detect duplicates during network registration. An IMEI already registered can be blocked or its registration refused. To avoid, internal manufacturer database + verification before assignment.

Costs and timing

Section titled “Costs and timing”

How much does a PTCRB module certification cost?

Section titled “How much does a PTCRB module certification cost?”

As market estimates (mostly lab testing; request quotes):

  • Complete 4G LTE module: $80,000 to $200,000
  • 5G NSA + 4G module: $120,000 to $250,000

The official CTIA Certification fee is $12,500 for an Initial Certification and $3,125 for a Variant (PPMD V4.1). Operator homologation fees come on top.

How long for a PTCRB certification?

Section titled “How long for a PTCRB certification?”

Indicatively:

  • Standard 4G LTE module: 6 to 9 months
  • Complete 5G module: 8 to 12 months
  • Device on a certified module: a few months

Operator homologations add several weeks per operator.

What happens for Mexico certification?

Section titled “What happens for Mexico certification?”

Mexico has its own regulator (IFT) requiring distinct homologation. PTCRB is not formally required but widely used as a reference, and Mexican operators commonly rely on PTCRB-certified modules; check each operator's own acceptance requirements.

FCC / GCF / other comparisons

Section titled “FCC / GCF / other comparisons”

Is my cellular product also subject to FCC?

Section titled “Is my cellular product also subject to FCC?”

Yes, mandatory. FCC validates compliance with radio emission limits (47 CFR Parts 22, 24, 27 depending on bands). PTCRB and FCC are conducted in parallel, many tests are shared (notably 3GPP RF Conformance).

What's the difference between PTCRB and GCF?

Section titled “What's the difference between PTCRB and GCF?”

PTCRB is North American (US + Canada). GCF (Global Certification Forum) is European and worldwide. Many European operators (Orange, Vodafone, Deutsche Telekom) require GCF. Tests are partially common, one lab can produce reports for both.

Can a product certified only in Europe (GCF) be sold in the US without PTCRB?

Section titled “Can a product certified only in Europe (GCF) be sold in the US without PTCRB?”

No. GCF is not recognised by North American operators. Distinct PTCRB certification is required, plus FCC certification. Many 3GPP tests are shared but North American-specific tests (OTA in US CTIA chamber, etc.) must be redone.

What is Verizon Open Development?

Section titled “What is Verizon Open Development?”

Open Development: the Verizon device certification program complementary to PTCRB. Covers aspects specific to Verizon networks (eUICC validation, certain LTE/5G bands). To target Verizon: PTCRB or GCF plus Open Development certification.

Post-market

Section titled “Post-market”

Is cybersecurity assessed by PTCRB?

Section titled “Is cybersecurity assessed by PTCRB?”

Partially. PTCRB does not explicitly certify cybersecurity like European RED 3.3. But 3GPP requirements integrate network security aspects (authentication, integrity). Operators may impose additional proprietary requirements.

How does operator homologation work after PTCRB?

Section titled “How does operator homologation work after PTCRB?”

Once PTCRB obtained, each operator typically adds their own specific requirements (Verizon Open Development, AT&T Network Ready, T-Mobile, etc.). Timing and cost vary by operator. It is possible to target a few priority operators rather than all.

How long must I retain the PTCRB file?

Section titled “How long must I retain the PTCRB file?”

Complete commercial lifetime + typically 5 to 10 years after end of production. PTCRB and operators may request access to test reports, IMEI traceability, and firmware revision history.

What happens with PTCRB requirement evolutions?

Section titled “What happens with PTCRB requirement evolutions?”

NAPRD03 and the test case database evolve several times a year. Hardware or software updates on an active certification go through ECO requests with delta tests. Budget an annual maintenance line per active module, driven by its update cadence.
