About Tanzania Calling Code
To reach Tanzania from another country, first dial the international calling code +255 — assigned by the ITU — followed by the local number. Tanzania is located in Africa, in Eastern Africa.
International calling codes follow the ITU-T standards E.123 and E.164, which define how phone numbers are written and dialed across borders. The prefix you dial after the exit code tells the global telephone network which national network to route the call to.
Where the +255 Calling Code Is Used
The country code +255 is assigned to Tanzania, located in Eastern Africa, with the capital Dodoma. This code is part of the international telephony numbering plan and is used for all calls made to Tanzania from outside the country.
When a number is written as +255 …, the +255 prefix directs your call to the Tanzania national network. After the prefix, dial the area code without its leading zero, then the subscriber number — the same pattern for landlines and mobiles.
ITU-T E.164 groups calling codes by world region; codes beginning with 2 cover the part of the world that includes Tanzania, in Eastern Africa. Storing numbers with +255 and omitting the domestic leading zero keeps contacts dialable from anywhere.
Tanzania Phone Number Formats
The ITU E.164 format for Tanzania numbers is +255 + area code + subscriber number, used for landlines and mobiles alike. Here is the general structure:
📱 Number Structure
- International format: +255 [area code] [subscriber number]
- From abroad: exit code + +255 + local number (drop the trunk prefix 0)
- Within Tanzania: dial the local number directly
Numbering plans vary: closed plans use fixed-length national numbers, while open plans allow variable lengths with a trunk prefix (usually 0) that is dropped for international calls. For calls to Tanzania, replace the trunk zero with +255.
Time Zone in Tanzania
The local time in Tanzania follows the Africa/Dar_es_Salaam time zone (UTC+03:00 UTC). Check the time difference before you dial so your call arrives during waking hours.
Time differences matter when calling Tanzania: if it is UTC+03:00 there, a morning call from Europe may reach Dodoma in the afternoon, while callers in the Americas should check the offset to avoid late-night calls.
If Tanzania observes daylight saving time, its UTC offset shifts by an hour twice a year. Double-check the current offset before time-sensitive calls, especially in spring and autumn.

Example: Calling Tanzania Numbers in Practice
Here is how a typical call to Tanzania works, depending on where you are calling from:
🌍 From the United States or Canada
- Dial the US/Canada exit code 011
- Dial the Tanzania country code +255
- Dial the local number (area code + subscriber number, without the trunk prefix 0)
Example: 011 +255 [area code] [number]
🌍 From the United Kingdom or Europe
- Dial the international access code 00 (or use the + symbol on mobile)
- Dial the Tanzania country code +255
- Dial the local number
Example: 00 +255 [area code] [number], or +255 [area code] [number] from any mobile phone
If the local number begins with a trunk prefix (commonly 0), remove it when dialing internationally — +255 takes its place. The remaining digits are dialed exactly as written.
