Nairobi is Kenya’s capital headquarters, where all government operations are coordinated. It is also one of the oldest towns, established in 1899. It officially became Nairobi County in 2013 as per the 2010 constitution, which abolished the Nairobi City Council government. Since the precolonial and even after the post-independence era, one thing that has remained essential but is evolving in Nairobi County is its postal system structure. While the Nairobi Postal codes might not have much significance in today’s modern Kenya, they are still essential, especially when it comes to the delivery and easy sorting of mail, among other functions.
In Nairobi, postal codes are also referred to as the Zone Improvement Plan ( Zip codes); the two are totally free, as we will cover later in the article, but at the end of the day, they serve a similar purpose. The Nairobi county population is always on the rise, with a late census in 2019 recording a population of about 4,397,073 inhabitants. For this reason, the city is always evolving, with new towns, countries, wards, etc., being formed to accommodate the needs of the larger population. As that happens, the Nairobi Postal codes are constantly evolving, with new Postal offices being introduced to cover specific areas.
So, what are the Nairobi Zip Codes? Well, this is just but one of the few questions this comprehensive guide will attempt to answer, along with many others. So, make sure to read to the end to ensure you have the correct zip and postal codes for your area.
What is the postcode in Nairobi?
When we talk of Postcodes in Nairobi, we are not just talking about the Nairobi region but also the entire country since the Postal Corporation of Kenya manages all Postcodes in the country, including those in Nairobi County. But then people have often asked whether Nairobi has Zip codes or Postcodes and, if so, what the difference is between them. A quick answer is that Nairobi has the postal code system structure, and so do all the remaining 46 counties in Kenya.
However, it should also be mentioned that there is not much difference between a postal code and a Zip code. The only difference lies in the geographical application. Zip codes are commonly used in the United States, while postal codes are commonly used here in Kenya ( Nairobi). The Nairobi postal code is 00100, which represents the General Post Office (GPO) for the entire Nairobi region.
Structure and Format
The Postal codes for Nairobi use a series of five digits used by the Kenya Posta codes for all parts of the country. For many of you who might not be connected with the Postal codes, these might seem like just ordinary numbers, but in a real sense, each digit plays a role
Posta Kenya has offices in various regions for Mailing purposes to keep the broad geographical area easy to identify. For example, in the Nairobi region with 00100, the first two digits (00 ) represent the Nairobi Postal Zone, and other counties in Kenya will not have these similar digits; they will have their own. The following last three digits (100) represented a specific delivery office in that particular area, in this case, the Nairobi GPO.
