Federal Capital Territory postal codes all sit in a single dispatch block, 900. Garki main head office is 900001, and FCT codes run up to 905001.
Abuja is the one place in Nigeria where addressing was planned before the city was built. Districts were laid out and named on paper first, so a Maitama or Gwarinpa address is precise in a way that Lagos and Port Harcourt addresses never managed to be.
That has an odd effect on postal codes here. They matter less day to day, because the district and street already identify the place, but the codes that do exist are more reliable than most in the country.
the FCT Postal Code at a Glance
| State capital | Abuja |
|---|---|
| Head office code | 900001 |
| Code range | 900001 to 905001 |
| Dispatch prefixes | 900 |
| Area Councils | 6 |
| Postal region | Region 9 |
| Digits | Six, numeric only |
Reading a the FCT Code
Take 900001, the Abuja head office code. The first digit, 9, puts the address in postal region 9. The first three digits, 900, 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 the FCT code is built the same way, which gives you a quick test. If someone hands you a code for an address in the FCT and it does not begin with 90, it is not a the FCT code.
Dispatch Districts in the FCT
Unlike every other state, the FCT runs on one dispatch prefix. Every code in the territory begins 900, and the districts you know by name, Garki, Wuse, Maitama, Asokoro, Gwarinpa, Kubwa, Lugbe and the rest, are delivery locations separated only by the last three digits. That is why FCT codes look so similar to each other, and why a single wrong digit here sends post to a district on the other side of the city rather than to a different state.
| Dispatch prefix | Codes it issues |
|---|---|
| 900 | 900001 to 900999 |
The 6 Area Councils in the FCT
The FCT has six area councils rather than local government areas. Abuja Municipal contains almost everything a visitor thinks of as Abuja, while the other five cover the satellite towns and the rural territory beyond the city.
| Abuja Municipal (AMAC) | Bwari | Gwagwalada |
| Kuje | Kwali | Abaji |
What you will not find above is a code beside each name, and that is deliberate. NIPOST issues codes to delivery districts, not to area councils. Tables that pair the two are estimates, which is why published lists for the FCT contradict each other and sometimes contradict themselves.
Ministries, Embassies and the Private Mail Bag
Abuja generates a category of post that barely exists elsewhere in the country. Ministries, agencies and commissions receive mail through private mail bags rather than street addresses. Embassies quote full codes on visa correspondence because their post is often forwarded internationally. The diplomatic zone in Maitama runs on addressing precise enough that letters actually arrive without a follow up call.
If you are completing a form for a federal office, use the private mail bag exactly as that agency publishes it, including the branch name attached to it. Substituting a street address for a published PMB is the most common reason official post goes astray in Abuja, because the agency’s internal mail room is organised around the bag and not around the building.
The Suleja Problem
The FCT sits at 900 and Niger State begins at 920, close enough that circulating code lists regularly file the border towns under the wrong one. Suleja is the sharpest case. Everyone who lives there treats it as an Abuja suburb, commutes into the city daily and gives an Abuja address on forms, but administratively it is Niger State and its postal codes come from Niger’s blocks.
If your address is in Suleja, Madalla or anywhere along that stretch of the Kaduna road outside the territory boundary, your code is a Niger State code. Using a 900 code will not stop a dispatch rider, who is navigating by landmark anyway, but it will fail any check that compares the code against the state you wrote.
Satellite Towns and the Rural Councils
Beyond Abuja Municipal, the territory contains five area councils covering towns that were there long before the capital was built. Gwagwalada, Kuje, Kwali, Bwari and Abaji are administrative centres in their own right, each with its own post office, and their codes sit in the same 900 block as the city districts.
The mismatch worth knowing about is that these councils are large and rural, so one delivery district can cover a wide area. A code that identifies a house in Wuse to within a few streets may identify only a general area in Kwali.
How to Write a the FCT Address
Abuja addresses are the closest thing Nigeria has to a fully planned system, so write them in full and they will resolve without a phone call.
The order NIPOST expects runs from the specific to the general, with the code on the same line as the town:
Mr I. Okonkwo House 12, 3rd Avenue Gwarinpa Estate 900108 Abuja Federal Capital Territory 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 9
the FCT 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 the FCT.
| State | Prefix |
|---|---|
| Niger | 920 |
| Plateau | 930 |
| Nasarawa | 950 |
| Benue | 970 |
Finding the Code for Your Street
- Ask at the counter of the post office that serves your street. Staff there work from the delivery district list daily and can give you the exact code.
- Search the NIPOST postcode finder by address rather than by local government.
- Where the delivery is informal anyway, use 900001, the Abuja head office code, which routes correctly across the state.
What to Enter on a Form
Type 900001 if you are in or near Abuja 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.
The New Code Coming in October
From 1 October 2026 Nigeria moves to a new 11 character postcode that identifies a single building rather than a sorting district. Abuja is also where NIPOST is demonstrating the new format. The published example code, FC02A09DB09, is an FCT address, with FC standing for the Federal Capital Territory and the characters after it stepping down through area council, district, area and building.

Frequently Asked Questions
What is the zip code for Abuja?
Garki main head office is 900001. Every FCT code begins 900 and the territory’s codes run up to 905001.
What is the postal code for Wuse?
Wuse is a delivery location inside the 900 block, so its code begins 900 and is identified by the last three digits. Ask at the Wuse branch for the exact figure rather than trusting a published table.
What is the postal code for Gwarinpa?
Gwarinpa also sits in the 900 block. Because the estate is one of the largest in West Africa, it spans more than one delivery round, so confirm the code for your specific phase.
Is Suleja part of the Abuja postal area?
No. Suleja is in Niger State and its codes come from Niger’s blocks, even though the town functions as an Abuja suburb. This is the most common FCT addressing error.
Does Abuja have local governments?
It has six area councils instead. Abuja Municipal covers most of the built up city, and the other five cover the satellite towns and rural territory.
Why do all Abuja codes look the same?
Because the whole territory shares one dispatch prefix. Only the last three digits change, which is unusual, since most states spread across several prefixes.
Is the Abuja area code the same as the postal code?
No. The telephone area code for Abuja is 0209 and it is used for landlines. The postal code is 900001 and it is used for addresses.
What will Abuja addresses look like after October 2026?
They will carry an 11 character code such as the published example FC02A09DB09, identifying an individual building rather than a delivery district.
Summary
The FCT uses one dispatch block, 900, with Garki main head office at 900001 and codes running to 905001. Six area councils make up the territory. Because Abuja was planned before it was built, its district and street names carry more weight than the code does, and federal offices are reached through published private mail bags rather than street addresses.
Conclusion
Use 900001 on forms. Use the exact published private mail bag for anything official. And if your address is in Suleja, remember that the postal system files you under Niger State no matter what your neighbours say.
