The Type Allocation Code (TAC) serves as a crucial identifier for all device types capable of connecting to a mobile wireless network, encompassing a wide range of devices such as IoT devices, payment terminals, and connected vehicles. This 8-digit number constitutes the initial segment of the 15-digit International Mobile Equipment Identity (IMEI), which plays a pivotal role in uniquely identifying each individual connected device. By assigning a distinct TAC to each device, they can be easily recognized and tracked globally, facilitating seamless transportation and operation across various regions and networks.

TAC/IMEI facilitates tax collection, global mobile network operation, and the identification of counterfeit or stolen devices, aiding governments, users, and authorities alike.
