History
The Tanzania Communications Regulatory Authority maintains the numbering plan as a regularly updated regulatory document. Version 1.16, effective 1 July 2026, distinguishes fixed, mobile, M2M, corporate, special-rate and premium-rate resources.
Each Tanzanian geographic code can cover several regions and many settlements. The code is useful for understanding fixed-line routing but cannot establish the present location or identity of a caller.

Largest Telephone Carriers
Current operator and market-share data are dynamic. This page avoids assigning a specific number to a carrier from its area code alone.
Landline
Area code 23 is a geographic fixed-line identifier. Consult Tanzania Communications Regulatory Authority for live allocation or licensing information.
Wireless
Wireless numbers commonly use separate non-geographic ranges. Number portability prevents reliable current-carrier identification from a prefix alone.
