MCC & MNC Lookup – Mobile Network Codes by Country and Operator

MCC (Mobile Country Code) and MNC (Mobile Network Code) are official telecom identifiers used worldwide to identify mobile networks. The MCC is a three-digit code that specifies the country (e.g. 310 for the United States). The MNC identifies a specific operator within that country (e.g. 410 for AT&T in the US). Together they form the PLMN (Public Land Mobile Network) code, which appears on SIM cards, in roaming agreements, and in network equipment.

These codes are used by GSM, LTE, and 5G networks for subscriber identification, roaming, and cell tower mapping. Use the lookup table below to search by MCC, MNC, country, or operator name and open the operator’s cell tower map when available.
