Most Nigerians don’t really know their area postal codes, and this is always required when filling applications online.
Nigeria Postal codes consist of six numbers. Nigeria is divided into nine regions by the Nigerian Postal Service. The first digit of the code represents the region while the second and the third digits combined with the first are the dispatch district for outgoing sorting.
Each main postal head office in every region has a postal code that ends with 00001. For instance, Garki main Head Office in Abuja postal code is 970001, Ikeja main Head Office in Lagos postal code is 100001, Lokoja in Kogi postal code is 270001 and Port Harcourt postal code is 500001.
