About GSMA Device Database

GSMA offers a device look up and identification service enabling you to identify the manufacturer and model of a mobile device from its IMEI. The information is indexed by TAC Code which is the first part of each IMEI.

GSMA is the global administrator of TAC codes and our database includes the TAC codes of all devices manufactured worldwide. The GSMA TAC/IMEI database is the only official and globally authoritative source of such information. New devices are added immediately as they are registered by manufacturers and some 200 device types are added each week. The database has been growing since GSM devices were first introduced in 1991 and contains all records. Please be cautious about using other sources as they may not be accurate.

The service is provided to Mobile Device Management (MDM), MVNO and platform solution businesses on a subscription for a regular weekly edition of the database.
