IMEI Number Allocation
The International Mobile Equipment Identity (IMEI) is a ![]()
15-digit decimal number used to identify terminal equipment when it is used on a GSM/UMTS mobile phone network. To ensure traceability of each item of equipment connected to the network, the IMEI must be unique and manufacturers must ensure no duplication of IMEI.
The overriding principles for the allocation and management of IMEI are preservation of the available number range, the prevention of duplication and the maintenance of security.
IMEI numbers are a global resource. The allocation of a TAC does not imply ownership of an IMEI by either the organisation to which the TAC is allocated or by the organisation performing the allocation function.
TÜV SÜD BABT are contracted by the GSM Association to allocate IMEIs and administer the GSM Association's IMEI database. This includes the registration of companies onto the IMEI database and the allocation of TAC (part of the IMEI) numbers.
The TAC number is the first 8 digits of the 15 digit IMEI. The TAC number is allocated on a per company and per model basis.
The IMEI structure is given here: IMEI Structure
To apply for TAC (IMEI) numbers, you must first register your company onto the IMEI database. If successful, you will be allocated a unique access code (Organization ID) and passwords. This will allow you to apply for TAC (IMEI) numbers.
