Location Area Code

Overview#

Location Area Code (LAC) is the internationally unique identifier for each Public Land Mobile Network (PLMN) used for location updating of mobile subscribers.

Location Area Code is composed of a three decimal digit Mobile Country Code (MCC), a two to three digit Mobile Network Code (MNC) that identifies a Subscriber Module Public Land Mobile Network (SM PLMN) in that country, and a Location Area Code (LAC) which is a 16 bit number with two special values, thereby allowing 65534 location areas within one GSM PLMN.

LTE Tracking Area Code (TAC) is a fixed length code (of 2 octets) identifying a Tracking Area within a Public Land Mobile Network (PLMN).
