The Type Allocation Code (TAC) is the initial eight-digit portion of the 15-digit IMEI and 16-digit IMEISV codes used to uniquely identify wireless devices.. The Type Allocation Code identifies a particular model (and often revision) of wireless telephone for use on a GSM, UMTS, LTE, 5G NR, iDEN, Iridium or other IMEI-employing wireless network.
Other administrators working under GSMA may also allocate any IMEI for use in dual-technology phones. For instance, Apple and LG normally use RR=35 which is allocated by BABT while Chinese brands such as Huawei use two RR=86 IMEIs allocated by TAF for 3GPP networks alongside a distinct RR=99 decimal or RR=A0 hexadecimal MEID for 3GPP2 networks.
However, a phone's IMEI may be easy to change with special tools. [10] [better source needed] In addition, IMEI is an un-authenticated mobile identifier (as opposed to IMSI, which is routinely authenticated by home and serving mobile networks.) Using a spoofed IMEI can thwart some efforts to track handsets, or target handsets for lawful intercept.
To avoid confusion the database of GSM Association was renamed to IMEI Database - IMEI DB [1] (it was in 2003-2008, see “Document History” at IMEI Database File Format Specification [2]). Also sometimes a common IMEI database for several EIRs is called SEIR (Shared EIR). In each country, the CEIR can interact with IMEI DB differently.
[11] Body-worn IMSI-catchers that target nearby mobile phones are being advertised to law enforcement agencies in the US. [12] The GSM specification requires the handset to authenticate to the network, but does not require the network to authenticate to the handset. This well-known security hole is exploited by an IMSI catcher. [13]

The StingRay does this by way of the following man-in-the-middle attack: (1) simulate a cell site and force a connection from the target device, (2) download the target device's IMSI and other identifying information, (3) conduct "GSM Active Key Extraction" [31] to obtain the target device's stored encryption key, (4) use the downloaded ...
