What is MCC/MNC?

The Mobile Country Code (MCC) and Mobile Network Code (MNC) are identifiers used globally for mobile networks. These codes are essential for identifying mobile operators and enabling devices to connect to the correct network.

What is an MCC?

The Mobile Country Code (MCC) is a three-digit code that uniquely identifies a country within the global telecommunications infrastructure. Every mobile network operator within a country shares the same MCC. Examples include:

• United States: 310–316

• Canada: 302

• Mexico: 334

• Germany: 262

What is an MNC?

The Mobile Network Code (MNC) is a two- or three-digit code that specifies a mobile network operator within a given country. The MNC, combined with the MCC, uniquely identifies a mobile network. Examples include:

• AT&T (USA): 310-410

• Rogers (Canada): 302-720

• Telcel (Mexico): 334-020

• Deutsche Telekom (Germany): 262-01

Why Are MCC and MNC Important?

These codes are fundamental to the operation of cellular networks for various reasons:

• Network Selection: Mobile devices use MCC and MNC to determine which network to connect to, whether at home or while roaming internationally.

• Roaming Agreements: Operators use these identifiers to manage international roaming, ensuring that customers can use their phones in other countries.

• Billing and Authentication: Network operators use these codes for accurate billing and authentication of users.
