The Lagos postal code is a six-digit number that ranges from 100001 to 112005. The capital of Lagos state is Ikeja, which is also the headquarters of the Nigerian Postal Service (NIPOST). Lagos state is divided into 20 local government areas (LGAs), and each LGA is further divided into districts and locations, each with its own specific postal code. For example, the postal code for Ikeja LGA is 100001, while the postal code for Lagos Island LGA is 101223. It is important to note that some LGAs share the same postal code, and postal codes are subject to change, so it is always a good idea to double-check for the most up-to-date information.
