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.
