Mobile Country Code (MCC)

In the dynamic landscape of mobile telecommunications, understanding the intricacies of Mobile Country Codes (MCC) is paramount. Let's embark on a journey to unravel the essence of MCC, its significance, and its role in identifying GSM networks.

Demystifying Mobile Country Codes 

At the core of GSM network identification lies the Mobile Country Code (MCC), a three-digit code designated by the ITU-T as standard E.212. Let's delve deeper into the fabric of MCC, exploring its fundamental aspects:

• Identifying GSM Networks: MCC serves as a unique identifier for GSM networks, delineating the geographical region to which a mobile subscriber belongs. By combining MCC with the International Mobile Subscriber Identity (IMSI), mobile networks can precisely pinpoint the origin of subscribers, facilitating seamless connectivity across borders.

• Geographical Correlation: The first digit of MCC offers insights into the geographical correlation of GSM service providers. From test networks to worldwide coverage, each digit signifies a distinct region, enabling efficient network management and localization of mobile services.

The Role of MCC in Network Identification 

MCC plays a pivotal role in network identification and differentiation, serving as a cornerstone for mobile network operators (MNOs). Let's explore how MCC collaborates with other identifiers to uniquely identify mobile networks:

• Combination with Mobile Network Code (MNC): MCC works in tandem with the Mobile Network Code (MNC) to create a globally unique identifier for mobile network operators. Together, MCC and MNC form the Home Network Identity (HNI), enabling precise identification and seamless roaming capabilities for mobile subscribers.

• Broadband Operator Identification: The amalgamation of MCC and MNC empowers broadband operators with a globally unique identification mechanism. By leveraging the HNI, operators can streamline network management, enhance security, and deliver enhanced connectivity experiences to subscribers.

Unveiling the Significance of MCC Codes 

Explore the diverse applications and implications of MCC codes in the realm of mobile telecommunications:

• Roaming Management: MCC codes play a crucial role in roaming management, enabling mobile operators to establish partnerships and agreements with other networks. By aligning MCC codes, operators can facilitate seamless roaming experiences for subscribers, ensuring uninterrupted connectivity across borders.

• Network Localization: MCC codes facilitate network localization, allowing mobile operators to tailor services and offerings based on regional preferences and regulations. By leveraging MCC codes, operators can optimize network resources, deploy targeted marketing strategies, and enhance subscriber satisfaction.

Summary

Mobile Country Code (MCC) is defined by ITU-T as standard E.212. MCC is a mobile code consisting of three digits used to identify GSM networks. MCC is also used along with the International Mobile Subscriber Identity (IMSI) to identify the region from which mobile subscriber belongs. The first digit of the MCC specifies the geographical correlation of the GSM service provider. Digit 1 and 8 are not used. below is the geographical distribution of the first digit.

0: Test networks

2: Europe

3: North America and the Caribbean

4: Asia and the Middle East

5: Australia and Oceania

6: Africa

7: South and Central America

9: Worldwide.

An MCC is used in combination with the Mobile Network Code (MNC) to uniquely identify a mobile network operator. A combination of the MNC and the MCC also known as an HNI (Home network identity) creates a globally unique Broadband operator identification.
