About the PLMN ID

A PLMN (Public Land Mobile Network) is uniquely identified by the pair (MCC, MNC). The MCC is a 3-digit Mobile Country Code assigned by ITU-T E.212, and the MNC is a 2 or 3-digit Mobile Network Code assigned by each country's telecoms regulator. Together they appear in almost every 3GPP identity: IMSI, SUPI, 5G-GUTI, S-TMSI, TAI, LAI, and GUAMI.

BCD packing on the air interface

On the NAS layer the PLMN ID is packed into 3 octets using Binary-Coded Decimal with nibble swapping: octet 1 = [MCC digit 2 | MCC digit 1], octet 2 = [MNC digit 3 | MCC digit 3], octet 3 = [MNC digit 2 | MNC digit 1]. If the MNC is only two digits, the unused MNC3 nibble is filled with hex F. So Reliance Jio (MCC 405, MNC 840) packs as 04 58 48 and Airtel Gujarat (MCC 404, MNC 05) packs as 04 F5 50.
