What is the PTCRB?

The PTCRB was established in 1997 as the wireless device certification forum by North American Mobile Network Operators (MNO).

The purpose of the PTCRB is to provide the framework within which cellular GERAN (GSM), UTRA (UMTS) and E-UTRA (LTE) mobile devices and modules obtain certification for use on PTCRB Operator networks.

PTCRB provides a certification program for the following:

  • GERAN devices operating in the 850 and 1900 MHz bands
  • UTRA devices operating in FDD Bands II, IV and V
  • E-UTRA devices operating in FDD bands 2,4,5,7,12,13,14,17 and 25; TDD band 41
    Note: bands subject to change as technology advances

Obtaining PTCRB Certification on a mobile device ensures compliance with 3GPP network standards within the PTCRB Operators' networks. Consequently, PTCRB Operators may block devices from their network if they are not PTCRB certified.

CTIA has been assigned as the administrator for the PTCRB Certification process and is also responsible for the administration of PTCRB-issued IMEIs.

It is recommended that the device manufacturer contact the MNO to obtain any operator-specific requirements.
