What each type means for the caller

Toll-free: 0800 or 0808
Free to the caller, usually only from inside the country; the business that owns the number pays for the call. 9 digits after +255.
Premium rate: 090
Charged above a normal call at a rate set by the service, with part of the charge going to the service provider. 9 digits after +255.
Shared cost: 0840, 0860 or 0861
The caller pays part of the cost and the owner pays the rest, so the price sits between a free and a normal call. 9 digits after +255.
VoIP: 041
Numbers issued for internet telephony services rather than a fixed line or a mobile network. 9 digits after +255.

Writing and dialling a Tanzania toll-free number

Inside Tanzania, dial the number with its leading 0. From abroad or in E.164, drop the 0 and put +255 in front: 0800 12 3456 becomes +255800123456. Google's data marks the toll-free range as not diallable from abroad, so these numbers usually only work from inside Tanzania.

Toll-free and premium numbers in a phone list

In a lead or customer list, a toll-free number usually reaches a company line rather than a person, and a premium-rate number costs you money to call. The free toll-free number checker flags them in a pasted list or CSV, and the Tanzania phone number format page covers mobiles and landlines.

Common questions

What is the toll-free prefix in Tanzania?
Tanzania toll-free numbers start with 0800 or 0808 at home, written +255 800 or 808 internationally. Every valid toll-free number starts that way, though not every number with those digits is in service.
How many digits is a Tanzania toll-free number?
9 digits after the country code +255, plus the trunk prefix 0 when dialled inside Tanzania.
Can I call a Tanzania toll-free number from abroad?
Google's numbering-plan data marks Tanzania's toll-free range as not diallable from abroad, so expect the call to fail from outside Tanzania.
How do I spot a premium-rate number in Tanzania?
By its first digits: 090. Shared-cost numbers start with 0840, 0860 or 0861. The prefix tells you the range is charged; the actual price is set per service.

The numbering plan only knows what a range was issued for.

In the US and Canada mobiles and landlines share the same prefixes, and anywhere a number can be ported or reassigned the range stops telling the whole story. A live carrier lookup asks the network data instead, which is what Pro + Phone ($49.99/mo) adds.
