Telephone numbers in Tierrador

In the Tierradorian Woqalate, telephone numbers are directly administered by the Tribunal Office of Media. For this purpose, the Media Office established the Tierradorian Telephone Numbering Plan (TTNP) in 1941, jointly administrating the newly-created plan with TK Group and Tierrador Telecom. In the initial numbering plan, 42 distinct area codes were created for the various regions of the nation (at the time, the La Plazal Region was independent but still part of the TTNP).

The TTNP divides its number format into the Telephone Plan Area (TPA), a 3-digit area code based on a specific area of the region, then a seven-digit unique subscriber number, for a total of 10 digits. For callers in the same TPA, the area code is typically omitted, however if an individual were to call someone outside the TPA, they would have to include the area code
