The TAC (Type Allocation Code) is an eight digit code which uniquely recognizes a cellular device's hardware configuration. It is issued by the GSMA and makes up the first eight digits of the IMEI serial number. In this article we provide a sample of different TAC numbers and identify a connection between TAC and DeviceAtlas datasets.
TAC database
TACs were introduced as a means of identifying a particular device make & model. The first TAC was allocated in 1992 for the Bosch Cartel T device. That year, only 51 TAC numbers were allocated.
Now in 2022, the number of allocations has extensively accelerated with more than fourteen thousand allocations per year. Up to 1 million IMEIs can be associated with a single TAC before another TAC must be generated.
