Understanding MCC and MNC

In the landscape of mobile telecommunications, two critical identifiers play a pivotal role in ensuring seamless connectivity and communication across the globe: MCC (Mobile Country Code) and MNC (Mobile Network Code). These identifiers are essential for the operation of mobile networks and facilitate numerous functions, including roaming, call routing, and network selection. This guide will delve into the definitions, functionalities, and significance of MCC and MNC within the context of Messangi's comprehensive customer engagement and CPaaS solutions.

What is MCC?

The Mobile Country Code (MCC) is a three-digit number uniquely assigned to each country or geographical area. The International Telecommunication Union (ITU) is responsible for the allocation and management of MCCs. This code is critical for international mobile communications, as it helps identify the country in which a subscriber's mobile phone is registered. MCC is the first component in identifying a mobile subscriber globally, paired with the Mobile Network Code (MNC).

What is MNC?

Following the MCC, the Mobile Network Code (MNC) is a two or three-digit number assigned to each mobile network within a country. The MNC is crucial for distinguishing between different mobile operators within the same country. When combined with the MCC, it creates a unique identifier for a mobile operator, enabling mobile devices to access the correct network and ensuring proper routing of calls and data.

Importance of MCC and MNC

  • Network Identification and Roaming: MCC and MNC are vital for identifying the home network of a mobile user and facilitating international roaming. When a user travels abroad, their mobile device uses the MCC and MNC to connect to a partner network, allowing them to make calls, send texts, and use data services seamlessly.
  • Call Routing: These codes are used to route calls and messages correctly, especially in scenarios involving international communication and roaming.
  • Subscriber Identification: In combination with the MSIN (Mobile Subscriber Identification Number), the MCC and MNC form the IMSI (International Mobile Subscriber Identity), which uniquely identifies a mobile subscriber across the globe.
  • Service Provisioning: For companies like Messangi, understanding and utilizing MCC and MNC codes is essential for delivering targeted and efficient services across different regions and mobile networks.
