Type Allocation Codes

Type Allocation Codes

Type Allocation Codes (TAC) are used to create International Mobile Equipment Identity numbers (IMEIs) for wireless devices. The IMEI is a unique 15 digit number and plays an important role in ensuring proper device operation on the network. The IMEI is defined and required by the GSM standards and is in daily use in networks globally.

GSMA and its appointed Reporting Bodies are the only globally recognized and official source of Type Allocation Codes (TAC) for creating IMEIs. Devices with improper or fraudulent IMEIs can be banned from networks and/or barred from distribution by government authorities. To ensure you receive an official TAC, please register your brand here and follow the official process for obtaining TAC.
