Adamawa State postal codes begin with 64 or 65. Yola head office is 640001, and the state’s codes run up to 652105.
Adamawa is in postal region 6 with Borno, Yobe and Taraba. The state runs along the Benue river valley with mountains on its eastern flank, and the postal blocks follow that valley because the roads do.

Reading a Adamawa State Code
Take 640001, the Yola head office code. The first digit, 6, puts the address in postal region 6. The first three digits, 640, 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 Adamawa State code is built the same way, which gives you a quick test. If someone hands you a code for an address in Adamawa State and it does not begin with 64, it is not a Adamawa State code.
Dispatch Districts in Adamawa State
The 640 to 642 blocks cover Yola, Jimeta and the local governments along the Benue corridor. The 650 and 651 blocks reach north to Mubi and the Mandara mountain areas. The two groups are separated by several hours of road, and Mubi functions as its own collection centre rather than routing everything through the capital.
| Dispatch prefix | Codes it issues |
|---|---|
| 640 | 640001 to 640999 |
| 641 | 641001 to 641999 |
| 642 | 642001 to 642999 |
| 650 | 650001 to 650999 |
| 651 | 651001 to 651999 |
| 652 | 652001 to 652999 |
The 21 Local Government Areas in Adamawa State
Adamawa has 21 local government areas running from the Benue lowlands up into the mountains along the Cameroon border. The terrain varies more here than in most northern states, and delivery times vary with it.
| Demsa | Fufore | Ganye |
| Girei | Gombi | Guyuk |
| Hong | Jada | Lamurde |
| Madagali | Maiha | Mayo Belwa |
| Michika | Mubi North | Mubi South |
| Numan | Shelleng | Song |
| Toungo | Yola North | Yola South |
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 Adamawa State contradict each other and sometimes contradict themselves.
Yola and Jimeta, One City With Two Names
Yola is the old town and the emirate seat. Jimeta, a few kilometres away, is the commercial and administrative half where the state secretariat, the markets and most modern development sit. Locals treat them as one place and often use the names interchangeably, but the post offices are separate and the delivery districts are distinct.
When writing an address, name the half you mean. Sending something to Yola when the recipient is in Jimeta will not lose it, but it will slow it down.
Mubi and the Northern Commercial Axis
Mubi is the state’s second town and one of the busiest market centres in the north east, with trade running across the Cameroon border. Its delivery districts handle a volume of commercial post closer to a capital’s than a secondary town’s, and it collects for the local governments around it rather than depending on Yola.
If your address is anywhere in northern Adamawa, work from Mubi rather than from the capital.
The Mountains and the River
East of the main road the land rises toward the Mandara range and the Cameroon border, and settlements there are scattered across difficult terrain. Delivery districts cover wide areas and post is collected from town offices rather than delivered.
Along the Benue itself, Numan and the river towns form a third small cluster with their own arrangements. The American University of Nigeria at Yola adds the standard campus pattern, with institutional post addressed to the department and campus.
If Your Address Is New or Unlisted
New estates and recently settled areas are where the code system lags hardest. 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 Adamawa 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 Adamawa State
A post office box is rented from a named branch, and the branch is what makes the address work. Written properly it is the box number, the branch, then the code and town. 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 Yola Main Post Office 640001 Yola Nigeria
Two practical notes. A box address is often more reliable than a street address in Adamawa 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 Adamawa State That Cannot Be Right
We tested the Adamawa State tables that circulate online for internal contradictions, meaning two local governments published with ranges that share the same numbers. Adamawa 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 Adamawa 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 Adamawa 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 Adamawa State
Knowing the chain explains why the first three digits matter more than the last three. A letter posted anywhere in Adamawa 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 6 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 Adamawa 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 640001 is a safe fallback and a random six digits is not.
How to Write a Adamawa State Address
Yola and Jimeta are treated as one urban area locally but they are distinct in an address, so name whichever one applies.
The order NIPOST expects runs from the specific to the general, with the code on the same line as the town:
Mal. H. Girei 21 Atiku Abubakar Way Jimeta 640001 Yola Adamawa 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 6
Adamawa 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 Adamawa State.
| State | Prefix |
|---|---|
| Borno | 600 |
| Yobe | 620 |
| Taraba | 660 |
Finding the Code for Your Street
- The only authoritative answer comes from the post office that delivers to you. Call the branch, give the street name, and ask which delivery district it falls under.
- Search the NIPOST postcode finder by address rather than by local government.
- Where the delivery is informal anyway, use 640001, the Yola head office code, which routes correctly across the state.
What to Enter on a Form
Type 640001 if you are in or near Yola 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
NIPOST switches the country to an 11 character alphanumeric postcode on 1 October 2026, built down five levels from state to individual building. Adamawa’s mountain communities gain the most locally, since they currently share district codes drawn around road access rather than around settlements.
