Phone number details
How to read a Tanzania phone number
A Tanzania number is +255 followed by 9 digits. Knowing which of those digits mark a mobile is what tells you what the call will cost before you place it.
Inside Tanzania, numbers are dialled with a leading 0. Drop it when calling from abroad — keeping it is the single most common reason an international call fails.
Mobile prefixes
Landline prefixes
Prefix ranges still identify a line as mobile or fixed even where a number has been ported between operators, because the mobile and fixed blocks are separate and numbers do not move between them. Operator identification from a prefix, by contrast, stopped being reliable once portability arrived.

Other African destinations, cheapest first
Rates vary by more than a factor of ten inside a single region, because each one is set by what the operator at the far end charges to accept the call. Algeria is currently the cheapest place we publish a rate for near Tanzania.

All toolsFrequently asked questions
What is the country code for Tanzania?
The country code for Tanzania is +255. Dial this after the exit code (or use + on a mobile).
What does a Tanzania phone number look like?
A Tanzania number is written as +255 22 234 5678: the country code +255 followed by 9 digits. That total is fixed by the national numbering plan, so a number with one digit missing is a typo rather than a shorter valid number.
How can I tell if a Tanzania number is a mobile?
By its leading digits. In Tanzania, a national number of 9 digits beginning with 6, 7 is a mobile. That still works after a number has been ported between operators, because mobile and fixed-line blocks are separate ranges and numbers do not move between them.
Do I need to drop the leading 0 when calling Tanzania?
Yes. Tanzania uses 0 as a trunk prefix for domestic calls. When dialing internationally, drop the leading 0 from the local number.
How much does it cost to call Tanzania?
Telvio charges $0.95/min to Tanzania landlines and $0.95/min to mobiles. Billing is per second with no connection fees, so you pay only for the seconds you talk.
