Year 256 (CCLVI) was a leap year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Claudius and Glabrio (or, less frequently, year 1009 Ab urbe condita). The denomination 256 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

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, this was discontinued following Tanzania's adoption of a new numbering plan, although calls between the three countries only required regional prefixes rather than international dialling. To call Uganda from Tanzania and Kenya, subscribers dial 006 instead of +256.
