Telephone numbers in Tanzania

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.
