United States MCC/MNC Codes

United States has been assigned 6 Mobile Country Codes by the International Telecommunication Union (ITU). Each operator combines one of them with its unique MNC to form its PLMN identifier:

• MCC 310 — 107 active operators

• MCC 312 — 72 active operators
• MCC 313 — 93 active operators

PLMN codes are used by mobile devices to identify and select networks, and by roaming agreements to route calls and data between operators globally. The 460 operators listed here represent all active MNC assignments reported by United States's telecommunications authority to the ITU.
