History of the Nigerian Postal Service (NIPOST)

You can trace the history of the Nigerian postal service to the year 1852 when the British Government opened the first post office in Nigeria. By 1898, the British Post Office was in Badagry, Epe, Ikorodu, Ijebu-Ode, Ibadan, and Abeokuta.

As of 1906, 27 Post Offices were operating, and at Independence in 1960, Nigeria had 1,000 Postal agencies, ten sub Post offices, and 176 Post Offices.

After Independence, the Government managed NIPOST as a Department until January 1, 1985. After that date, NIPOST joined the Nigeria Telecommunications Limited (NITEL.) as a Department.

Later by decree No. 18 of 1987, NIPOST became an Extra-Ministerial Department. According to Wikipedia, NIPOST employs over 20, 000 and has more than 5, 000 offices nationwide.

Functions of NIPOST

Some of the tasks of NIPOST include:

  • Providing Private Mailbox and Private Mail Bags
  • Receiving posted letters, sorting, and delivering them on time to recipients locally and Internationally.
  • Selling stamps and the collection of stamp duty for the Federal Government
  • Granting Postal Agency permit to Rural areas without a Post Office
  • Bulk post services for events like AGM, Newsletters, and Enquiry slips
  • Do EMS Speed post-Globally and Special parcel service delivery

Composition of the Nigeria Postal Codes (zip codes)

Using the postcode method, Nigeria is divided into nine postcode zones. Each postcode zone is represented by numbers one to nine, and it is the first digit on postal code.

For example, Lagos and Ogun states are Number 1, and Abuja, Niger, Nasarawa, and Benue states are number 9.

Also, a postcode zone is divided into postcode areas, which are identified by a postcode. Nigeria postcode completely covers all the regions of the country’s spaces.

NIPOST Mail-delivery system

With the use of postal codes, NPOST delivers mails in three forms adequately and efficiently. The mail delivery system includes:

  • delivery of mails at post offices and postal facilities (into mailboxes and private mail bags)
  • delivery of mails to large towns by Postmen
  • distribution of letters to rural areas.

Nigeria postal codes or zip codes; is there a difference?

Zip code is the same thing as the postal code. The United States of America makes use of a ZIP code instead of postal code. But Zip code, like Nigeria’s postal code, are specific digits that enable easy sorting and delivery of mails.

Also, if you would like to know what Zip means, here is what each letter stands for. “Z” stands for a zone,  “I” stands for improvement, and “P” stands for plan.

So, the next time you are online, and you are filing a form, just note that the postal code in Nigeria is the same as the ZIP code in America. Do not enter Nigeria’s telephone code 234 and imaginary numbers. Instead, find out the exact Postal code for your state and use it.
