Tanzania Calling Code FAQ
- What is the calling code for Tanzania?
- +255. From abroad, dial your exit code (or +), then 255, then the national number. If a Tanzania number is written domestically with a leading 0, drop that 0 after +255.
- Is it +255 or 255?
- Same code. +255 is the portable form for contacts and mobiles. 255 is what follows an exit code, for example 011 255… from the US.
- Do I drop the leading 0?
- Yes, if the number is written domestically with a leading 0: 0XX… → +255 XX… (drop the 0 after +255).
- How do I call Tanzania from the US or UK?
- From the US, dial 011 255 XX… (the number without its leading 0). From the UK and most of Europe, dial 00 255 XX… in the same way. On a mobile, you can use +255 XX… instead.
