History
TPRA’s published history describes a plan that began with fixed geographic areas, changed geographic-code and subscriber-number lengths in the mid-1990s, and added mobile numbering in 1998. ITU assigned the newly independent South Sudan country code +211 in 2011, while Sudan retained +249. TPRA has continued modifying non-geographic mobile resources, including new assignments published through ITU in December 2024 and April 2025.
