Telephone numbers in Tanzania

Country Code: +255
International Call Prefix: 000
Trunk Prefix: 0

Until 1999, Tanzania, Kenya and Uganda shared a telephone numbering plan, in which subscribers were only required to dial the trunk code, area code and number. In that year, Tanzania adopted a new numbering plan. Calls to Kenya and Uganda require a regional prefix rather than having to use full international dialling. To call Kenya from Tanzania, subscribers dial 005 instead of +254, while to call Uganda, they dial 006 rather instead of +256. To call Tanzania from Kenya and Uganda, subscribers dial 007 instead of +255.

Format

• +255 XXX XXX XXX or +255 XX XXX XXXX - calling from outside Tanzania call this numer 101 or 2233
• 0XXX XXX XXX or 0XX XXX XXXX - calling within Tanzania

The NSN length is nine digits.

• Subscriber Number length under 2X, 4X, 6X and 7X NDCs is 7 digits.
• Subscriber Number length under 8XY and 90X NDCs is 6 digits.
