Kwara State postal codes begin with 24 or 25. Ilorin head office is 240001, and the state’s codes run up to 252104.
Kwara sits in postal region 2 with Oyo, Osun and Kogi, which places it postally in the south west even though the state straddles the boundary between northern and southern Nigeria in almost every other respect.

Reading a Kwara State Code
Take 240001, the Ilorin head office code. The first digit, 2, puts the address in postal region 2. The first three digits, 240, name the dispatch district that sorts outgoing mail. The last three, 001, are the delivery location, and 001 always means the head office itself.
The same three part structure explains why codes inside one town look almost identical while codes from opposite ends of the state look unrelated. Two houses on the same street usually share all six digits, because they share a delivery round. Two houses in different towns rarely share more than the first three.
Every genuine Kwara State code is built the same way, which gives you a quick test. If someone hands you a code for an address in Kwara State and it does not begin with 24, it is not a Kwara State code.
Dispatch Districts in Kwara State
The 240 and 241 blocks cover Ilorin and the local governments immediately around it, which hold most of the state’s population and nearly all of its institutional post. The 243 and 251 blocks reach outward to Offa, Jebba and the western local governments toward the Niger boundary, where settlements are far apart and delivery districts are correspondingly wide.
| Dispatch prefix | Codes it issues |
|---|---|
| 240 | 240001 to 240999 |
| 241 | 241001 to 241999 |
| 243 | 243001 to 243999 |
| 250 | 250001 to 250999 |
| 251 | 251001 to 251999 |
The 16 Local Government Areas in Kwara State
Kwara has 16 local government areas. Three of them, Ilorin East, Ilorin South and Ilorin West, divide the capital, and the rest cover a state that stretches a long way west toward the Benin Republic border.
| Asa | Baruten | Edu |
| Ekiti | Ifelodun | Ilorin East |
| Ilorin South | Ilorin West | Irepodun |
| Isin | Kaiama | Moro |
| Offa | Oke Ero | Oyun |
| Patigi |
What you will not find above is a code beside each name, and that is deliberate. NIPOST issues codes to delivery districts, not to local governments. Tables that pair the two are estimates, which is why published lists for Kwara State contradict each other and sometimes contradict themselves.
Ilorin, and a City That Reads Both Ways
Ilorin is an emirate city with a Yoruba speaking population, and the addressing reflects that dual character. The older quarters are organised into wards in the northern pattern, where the ward name and a landmark identify a place far better than a street number. The newer areas, the GRA, Tanke and the university corridor, use the southern pattern of named roads and numbered plots.
When writing an Ilorin address, follow whichever pattern the area uses. Ward and landmark for the old city, road and number for the newer districts, and the town and code on the same line either way.
The University Corridor
The University of Ilorin sits south of the city and has pulled a substantial residential corridor along with it. Tanke and the surrounding areas grew quickly around the campus, which means addressing there is newer than the districts serving it, and codes tend to belong to the nearest older district rather than to the estate itself.
Campus post follows the standard Nigerian pattern of department and campus rather than a district code.
Offa, Jebba and the Western Reach
Offa is the state’s second town and a commercial centre in its own right with its own delivery districts. Jebba, on the Niger, is a rail and river crossing point and functions as a collection node for the settlements around it.
West of those, Baruten and Kaiama cover a great deal of thinly settled ground reaching toward the international border. A code there identifies a town, not a neighbourhood, and the community name is what completes the address.
If Your Address Is New or Unlisted
Newly built areas sit in a gap: the houses are there, the delivery district has not caught up. A delivery district is drawn when an area has enough post to justify a round, so a new estate is usually absorbed into the nearest existing district rather than given its own. That means your code is real, but it belongs to the district next door rather than to your street.
Three things help. Use the code your delivery office gives you even if it seems to belong somewhere else, because that is the round your post is on. Put the estate name and the nearest main road in the address, since those carry the item the last kilometre. And keep a phone number on anything that matters, because in Kwara State as everywhere else in Nigeria, the last stage of delivery is a call rather than a code.
Post Office Boxes and Private Mail Bags in Kwara State
A rented box belongs to one branch, so the branch name carries the address. Leave it out and the box number means nothing. A private mail bag works the same way but is issued to an organisation rather than an individual, which is why ministries, universities and large companies publish one instead of a street address.
The layout looks like this:
P.O. Box 1234 Ilorin Main Post Office 240001 Ilorin Nigeria
Two practical notes. A box address is often more reliable than a street address in Kwara State, because it removes the guesswork about which delivery district covers you, and it survives you moving house. But couriers who deliver to the door, which is most of them, cannot deliver to a box at all, so keep a street address for anything that arrives by bike.
Codes Published for Kwara State That Cannot Be Right
We tested the Kwara State tables that circulate online for internal contradictions, meaning two local governments published with ranges that share the same numbers. Kwara State shows none, which puts it among the cleaner states in the country.
That is worth something, but be careful what you read into it. Consistency is not accuracy. It means nobody has published two ranges that openly contradict each other for Kwara State, not that NIPOST ever issued a code to a local government. The safe reading stands: treat block level information as solid and treat any single code attached to a local government as an estimate until your delivery office confirms it.
It is worth knowing how wrong codes get into circulation in the first place, because the same three routes explain almost every bad table online. The first is interpolation, where somebody knows two real codes and fills the gap between them with a tidy range. The second is inheritance, where one site guesses and forty others copy it, which is why a wrong code can look authoritative through sheer repetition. The third is drift, where a code was right when it was published and the delivery district was later split or merged.
You can check any Kwara State code you are given in two steps. Confirm it starts with one of the dispatch prefixes listed above, which rules out codes belonging to another state entirely. Then confirm the last three digits with the delivery office, which is the only part no table can settle for you.
What Happens to a Letter Posted in Kwara State
Knowing the chain explains why the first three digits matter more than the last three. A letter posted anywhere in Kwara State is collected to the nearest branch, then moved to the dispatch office named by the first three digits of the destination code. Outgoing post leaves the state through the region 2 network, and incoming post arrives the same way in reverse, landing at the dispatch office before it is broken down to the delivery round in the last three digits.
The code earns its keep on registered and tracked items. Ordinary post in Kwara State is forgiving, because a postman who recognises the street will deliver it regardless of the digits. A registered item, an EMS parcel or anything arriving from abroad is handled against the code at each transfer, so a wrong dispatch prefix on those can add days or send the item back.
Get the first three digits wrong and your letter travels to the wrong part of the country before anyone notices. Get the last three wrong and it usually still arrives, a day late, because the delivery office recognises the street. This is why a head office code such as 240001 is a safe fallback and a random six digits is not.
How to Write a Kwara State Address
Ilorin addresses use area names heavily, and the older parts of the city are organised by ward rather than by street.
The order NIPOST expects runs from the specific to the general, with the code on the same line as the town:
Alhaji S. Ibrahim 11 Ahmadu Bello Way GRA 240001 Ilorin Kwara State Nigeria
Two habits worth breaking. Do not put the code on its own line at the bottom the way American addresses do, because Nigerian sorting reads it beside the town name. And do not drop the state, even for a well known city, because several towns share names across states and the state is what disambiguates them.
Neighbouring Codes in Region 2
Kwara State shares its postal region with the states below. If a code you have been given starts with one of their prefixes, the address is not in Kwara State.
| State | Prefix |
|---|---|
| Oyo | 200 |
| Osun | 220 |
| Kogi | 260 |
Finding the Code for Your Street
- Your delivery office holds the list that matters. Give them the street and the nearest landmark, and they will tell you which district code covers it.
- Search the NIPOST postcode finder by address rather than by local government.
- Where the delivery is informal anyway, use 240001, the Ilorin head office code, which routes correctly across the state.
What to Enter on a Form
Type 240001 if you are in or near Ilorin and do not know your district code. Six digits, no spaces. Avoid 23401 and 00000, which are not NIPOST codes and mean nothing to a sorting office even though most websites accept them.
If a foreign site rejects the code because it wants five digits, that is a validation fault on their end rather than a problem with your address. Enter the six digits wherever the form allows it, and never invent a shorter code for anything a bank, an embassy or a courier will check.
The New Code Coming in October
A new national postcode arrives on 1 October 2026. It runs 11 characters and goes all the way down to the building. Kwara’s western local governments are the clearest local case for the change, since a single district code currently stands in for a very large area.
