Nigerian postal codes, also known as ZIP codes, are numeric or alphanumeric strings that facilitate the sorting and delivery of mail within the country. The Nigerian Postal Service (NIPOST) divides Nigeria into nine regions, the first digit of the postal code represents each of these regions. The second and third digits, combined with the first, are the dispatch district for outgoing sorting. Finally, the last three digits represent individual post offices within the dispatch district.
For instance, Abuja, the capital city of Nigeria located in the Federal Capital Territory, has postal codes ranging from 900001 to 900288. Lagos State, Nigeria's economic hub, has varying codes like 100001 for Ikeja and 101001 for Lagos Island, reflecting its diverse and extensive postal needs. In the northern region, Kano State's codes start with 700001, catering to its populous nature. Down south, Rivers State, with Port Harcourt as its capital, uses postal codes like 500001. Each state in Nigeria, all 36 of them, plus the Federal Capital Territory, has its unique set of postal codes designed to streamline mail delivery and ensure efficiency across this vast nation.
