Reporting Body Identifier

The Reporting Body Identifier is the first two digits of a Global System for Mobile Communications (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 code (CC) of the organization identified, as most approving nations used a single approval body endorsed by their national GSM Association chapter. However, not all Reporting Body Identifiers follow this tendency.

Reporting Body Identifier codes[edit]

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

Code Group/indication Origin
00 Test IMEI Nations with 2-digit CCs
01 PTCRB United States
02 - 09 Test IMEI Nations with 3-digit CCs
10 DECT devices
30 Iridium United States (satellite phones)
33 DGPT France
35 BABT United Kingdom
44 BABT United Kingdom
45 NTA Denmark
49 BZT / BAPT Germany
50 BZT ETS Germany
51 Cetecom ICT Germany
52 Cetecom Germany
53 TÜV Germany
54 Phoenix Test Lab Germany
86 TAF China
91 MSAI India
98 BABT United Kingdom
99 GHA For multi RAT 3GPP2/3GPP

Normally, when a RBI is 35, the phone device supports operation on the 1800 MHz band, but if it is 01, it will not have it, e.g., Motorola and Nokia. There are some exceptions for RBI 01, e.g., on LG and Sony Ericsson.

Reporting Body Identifier vs Regional Code[edit]

The "Reporting Body Identifier" is also known as the Regional Code in the CDMA context. The International Mobile Station Equipment Identity (IMEI) and Mobile Equipment Identifier (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 terms the GSMA is the Global Decimal Administrator while the Telecommunications Industry Association (TIA) is the Global Hexadecimal Administrator.
