This project aims to provide a publicly, community-maintained, and well-organized database to collect Type Allocation Codes (TACs). While other databases exist, they either don't provide the full data set (e.g. by providing a query interface with rate limiting) or are not maintained in a way that we consider helps the community (submission process cumbersome, data not cleaned/sanitized,...).
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.
