How the Plan Developed
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.
Coverage and identity limitation
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.
Common questions
Tanzania Phone Code FAQ
What is the country calling code for Tanzania?
Tanzania uses country calling code +255.
Do I keep the domestic prefix when using +255?
No. Remove the leading domestic trunk zero before adding +255.
Can an area code identify a caller’s exact location?
No. It describes a numbering area or historic allocation, and portability, forwarding and internet telephony can separate a number from the caller’s present location.
