What is Nigeria’s ZIP code? Clear the Confusion Now!
If you’ve been confused for some time about what the correct Nigeria ZIP code is, then this post is for you, as it gives some clarification.

For your information, ZIP (Zone Improvement Plan) codes apply ONLY to the United States. The US does not regard postal codes from other countries as “ZIP” codes.
In all other countries, postal codes are used. However, ZIP codes in the US are used for the same purposes for which other countries use postal codes — for mailing purposes.
So, ZIP codes are to the US while postal codes are to other countries — including Nigeria.
However, note that the USPS (United States Postal Service) has codes for overseas countries, which are used when handling deliveries. These codes are equivalent to the ZIP codes used within the US. The code for Nigeria is 00176-0000.
Now, how do you fill forms requesting for ZIP code?
If you’re filling a form online, and you’re required to key in your ZIP code, simply put 110001 or 23401. Some sites may reject both codes. In such case, try 00176. At least one of these codes should work.
Don’t make this mistake, please…
Never enter 234 as the ZIP code for Nigeria. This is Nigeria’s international phone dialling code. (Whenever you’re required to enter a ZIP code, simply use 110001, 23401, or 00176.)
