Tanzania at a glance
The numbers and facts you need before you dial.
What is the country code for Tanzania?
Tanzania picks up calls on +255, the code that covers both the mainland and Zanzibar. Place it after your exit code on any international call. Inside the country every number wears a trunk 0 — 022 for a Dar es Salaam fixed line, 07xx for the mobiles most people actually use — and that 0 gives way to +255 the moment the call comes from abroad.
Code +255 was assigned to Tanzania by the ITU under the E.164 plan. The “+” means “dial your local international exit code”; on a mobile, press and hold 0 to type it.
All four mean the same thing — they connect your call to Tanzania.
How to call Tanzania from anywhere
The pattern is the same whether you're ringing a Dar es Salaam office or a guesthouse in Zanzibar: exit code, then 255, then the national number with its leading 0 stripped off.
Full example: +255 22 XXX XXXX — drop the local leading 0 when calling from abroad.
Tanzania phone number format explained
Behind +255 sits a tidy 9-digit national number (the domestic version simply adds the trunk 0 in front). Drop that 0 for the +255 form and the digit count tells you the rest.
Landline
0 + area code (2 digits) + 7 digits. Example: Dar es Salaam 022 XXX XXXX → +255 22 XXX XXXX.
Mobile
0 + 6X/7X + 7 digits. Example: 07XX XXX XXX → +255 7XX XXX XXX. Tanzanian mobiles open with 06 or 07 — note that 06 range, which trips up callers used to 07-only countries.

Tanzania mobile network prefixes
The prefix after +255 tells you which network issued the SIM — though number portability means it no longer guarantees the operator.
Vodacom Tanzania
Airtel Tanzania
Yas / Tigo
Halotel
Zantel (Zanzibar)
TTCL Mobile
Tanzania time zone
Dar es Salaam and Zanzibar share one steady clock: East Africa Time, UTC+3, with no daylight saving to track. The offset never moves, so a call window you set in January still holds in July.
09:00–16:00 EAT covers the Tanzanian working day. A Dar es Salaam morning meets the European morning and the Gulf afternoon — useful, given how much Tanzanian trade runs through Dubai and the Indian Ocean rim.

Almost every failed international call is a formatting issue, not a network issue.
Assuming the capital is where the business is: Dodoma is Tanzania's official capital (area code 26), but Dar es Salaam (22) remains the commercial heart
aim your fixed-line calls accordingly, and don't be surprised that "the capital" isn't the busiest number.
Leaving the trunk 0 in: never dial +255 0…
the 0 drops once +255 is on.

Visiting? A local eSIM (Vodacom, Airtel, Yas or Halotel) gets you data and on-net calling
and on safari or the islands, data coverage often beats roaming voice.
