Every device must be clearly identified before AT&T device certification is completed. This page explains three alternatives for identifying your IoT device so that it can run on the AT&T network.
IoT devices operating on mobile cellular networks are sometimes difficult to correctly identify. This is due to the high quantity of connected IoT devices, and the fact that traditional mobile phone identification methods do not always work well with IoT. Therefore, all new devices going through AT&T Device Certification must be identified by one of two methods.
Method 1: Identification through assignment of a unique type allocation code (TAC) to your integrated device
The TAC is the first eight digits of the IMEI number. Obtaining a dedicated TAC means requesting a TAC range assigned to your device (and only your device) from an authorized authority, which will cover 1 million unique IMEIs. AT&T needs to know the dedicated TAC assignment prior to certification completion.
Devices sharing a family TAC (F-TAC) must also utilize the IMEI Upload method for identification of each variant within that family, per ID Through IMEI, and comply with the periodic update requirements therein.

For your convenience, we have an IMEI File Upload Tool to submit your file in .csv format through ProjectOne (Navigate to “IMEI File Upload”) or an API upload .
