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 geographic areas, networks and subscriptions. The main body of this Recommendation describes the pure identification plan.

Amendment 2 introduces Annex G, which contains the criteria and procedures for an applicant to be temporarily assigned a two-digit mobile network code (MNC) within the shared ITU-T E.212 mobile country code 991 for the purpose of conducting an international non-commercial trial.
