What is a TAC?
A Type Allocation Code (TAC) is made up by the first 8 digits of the so-called International Mobile Station Equipment Identity (IMEI) associated with mobile devices. Earlier versions of the 3GPP TS 03.03 specification defined it as 6 bytes. The TAC is a unique identifier to determine the device manufacturer/model and its marketing name.
These records are allocated by certain groups and a full list of all IMEIs is maintained by the GSMA.
