PTCRB, frequently asked questions
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 PTCRB member operators?
Section titled “Who are PTCRB member operators?”Main North American operators, AT&T, T-Mobile, Verizon (USA), Bell, Rogers, Telus (Canada), plus regional operators. Verizon also has its own OPC program complementary to 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 Modular Certification and End-Product Certification?
Section titled “What's the difference between Modular Certification and End-Product Certification?”Modular Certification certifies a cellular module (integrable RF card) that can then be reused by integrators. End-Product Certification certifies the complete final product. EPC on certified module is simplified (30-60% of cost/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 Modular Certification. You only need to pass a simplified End-Product Certification (essentially OTA in final configuration + integration verification). Cost and timing divided by 2 or 3.
What happens for 2G/3G sunsets?
Section titled “What happens for 2G/3G sunsets?”- 3G UMTS, sunset completed on AT&T US (end 2022), still active in Canada.
- 2G GSM, progressive US sunset, still active Canada.
- 2G/3G modules no longer certified since 2024 on AT&T.
For long-duration IoT products, switch to Cat-M or NB-IoT which have long network roadmaps (≥ 2035 typical).
IMEI and identifiers
Section titled “IMEI and identifiers”What is an IMEI TAC?
Section titled “What is an IMEI TAC?”Type Allocation Code: 8-digit identifier assigned by GSMA to the PTCRB-certified model. Allows 1 million IMEIs unique. Multiple TACs may be 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 digitsExample: 35123456 123456 7The 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?”- Complete 4G LTE module: $80,000 to $200,000
- 5G NSA + 4G module: $120,000 to $250,000
- Complete 5G SA module: $200,000 to $350,000
Operator homologation fees additional ($5,000 to $20,000 per operator).
How long for a PTCRB certification?
Section titled “How long for a PTCRB certification?”- Standard 4G LTE module: 6 to 9 months
- Complete 5G module: 8 to 12 months
- End-Product Certification: 2 to 4 months
Operator homologations add 4 to 12 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 reference. Most Mexican operators accept FCC + PTCRB-certified modules without additional tests.
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 OPC?
Section titled “What is Verizon OPC?”Open Product Certification: Verizon-specific program complementary to PTCRB. Covers aspects specific to Verizon networks (CDMA legacy, certain LTE/5G bands). To target Verizon: PTCRB + OPC required.
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 OPC, AT&T NDD, T-Mobile 5G SA, 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 test plan evolutions?
Section titled “What happens with PTCRB test plan evolutions?”Test plans evolve typically twice a year. For active certifications, partial recertification (delta tests) required. Annual maintenance cost: $10,000 to $30,000 per active module.
