A Type Allocation Code (TAC) is an 8-digit number for 3GPP devices that identifies the make and model – which is why different device models require different TAC. Manufacturers use TAC to create a unique number that identifies individual mobile devices, known as the International Mobile Equipment Identity (IMEI).
