Summary

Recommendation ITU-T E.212 defines a unique international identification plan for public fixed and mobile networks providing users with access to public telecommunication services. The ITU-T E.212 identification plan was originally developed for use in public land mobile networks (PLMNs). The plan is hierarchical and identifies geographical areas, networks and subscriptions. The main body of this Recommendation describes the pure identification plan.

The 2024 revision of this Recommendation clarifies the conditions for reclamation in the case of non-payment of membership fees for mobile network codes (MNCs) under shared ITU-T E.212 mobile country codes (MCC).
