Reporting Body Identifier

The Reporting Body Identifier is the first two digits of a GSM Type Allocation Code, and indicates the GSMA-approved organization that registered (or, before 2002, approved) a given mobile device, and allocated the model a unique code.

The numbers are loosely based on the telephone country codes of the organization identified, as most approving nations used a single approval body endorsed by their national GSM Association chapter. However, not all RBIs follow this tendency.

Reporting Body Identifier codes

According to "Permanent Reference Document TW.06, Appendix A" of the GSM Association, the current RBI codes indicate the following approval/allocation bodies:

Normally, when a RBI is 35, phone have 1800 band, but if its 01, will not have it,(Motorola, Nokia). There are some exceptions for the RBI 01, on LG and Sony Ericsson

Reporting Body Identifier vs Regional Code

The "Reporting Body Identifier" is also known as the Regional Code in the CDMA world. The IMEI and MEID structures are superficially the same except that the first two digits must be decimal for an IMEI, and must be hexadecimal for an MEID. In 3GPP2 speak the GSMA is the Global Decimal Administrator while the TIA is the Global Hexadecimal Administrator.
