Mobile Country Code (MCC)


The Mobile Country Code (MCC) is a unique three-digit code used in signaling networks and SIM cards as part of the International Mobile Subscriber Identity (IMSI) to identify the country where a mobile operator or user is based. This code helps in categorizing users by their country of origin in global communications networks.

The distribution of the first digits of an MCC is as follows:

  • 0: Test Network
  • 2: Europe
  • 3: North America and the Caribbean
  • 4: Asia and the Middle East
  • 5: Australia and Oceania
  • 6: Africa
  • 7: Central and South America
  • 9: Worldwide

Note: Numbers 1 and 8 are not used. Additionally, it’s possible for a country to have more than one Mobile Country Code.

The MCC, combined with the Mobile Network Code (MNC), forms the Home Network Identity (HNI), which is a globally unique identifier for a mobile network operator.

Example of Mobile Country Code in a sentence:

"The United States has two Mobile Country Codes: 310 and 311."
