Bayelsa State postal codes begin with 56. Yenagoa head office is 560001, and the state’s codes run only as far as 561102, the narrowest range of any state in Nigeria.
That narrow range is not an oversight. Bayelsa has eight local government areas, the fewest in the country, and most of the state is water. There are simply fewer places to code.
Bayelsa State Postal Code at a Glance

| Code range | 560001 to 561102 |

| Local Government Areas | 8 |
| Postal region | Region 5 |
| Digits | Six, numeric only |
Reading a Bayelsa State Code
Take 560001, the Yenagoa head office code. The first digit, 5, puts the address in postal region 5. The first three digits, 560, 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 Bayelsa State code is built the same way, which gives you a quick test. If someone hands you a code for an address in Bayelsa State and it does not begin with 56, it is not a Bayelsa State code.
Dispatch Districts in Bayelsa State
Two blocks serve the entire state, 560 and 561. Yenagoa and the local governments reachable by road sit in the first, and the creek and coastal areas are served through the second. No other state in Nigeria runs on so few dispatch codes, and the reason is geography rather than population.
| Dispatch prefix | Codes it issues |
|---|---|
| 560 | 560001 to 560999 |
| 561 | 561001 to 561999 |
The 8 Local Government Areas in Bayelsa State
Bayelsa has eight local government areas: Brass, Ekeremor, Kolokuma Opokuma, Nembe, Ogbia, Sagbama, Southern Ijaw and Yenagoa. Southern Ijaw alone is larger than several entire states in the south west, and almost all of it is water.
| Brass | Ekeremor | Kolokuma/Opokuma |
| Nembe | Ogbia | Sagbama |
| Southern Ijaw | Yenagoa |
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 Bayelsa State contradict each other and sometimes contradict themselves.
A State Made of Water
Bayelsa is the most riverine state in Nigeria. Outside Yenagoa and the road corridor running north to Mbiama, most communities are reached by boat, and some are a two hour journey from the nearest road. This shapes postal delivery completely.
In practice, post for creek communities is held at the nearest town office and collected rather than delivered. The code identifies the office. The community name, and a phone number, do the rest. Anyone promising door to door delivery deep into Southern Ijaw is describing an arrangement they have made privately, not a postal service.
Yenagoa and the Road Corridor
Yenagoa became a capital in 1996 and grew quickly, with the Mbiama Yenagoa road as its spine. Government offices, the university and the oil servicing companies concentrate along it, and the delivery districts covering that corridor are the only ones in the state that function like a normal urban postal area.
The town’s telephone area code is 02089, changed from 089 in 2023, and it is unrelated to the postal code.
Oloibiri, Brass and the Oil History
Oil was first found in commercial quantity at Oloibiri in Ogbia local government in 1956, and Brass on the coast holds terminal facilities. Industrial addressing in those places is precise because the operators maintain it, but it sits alongside community addressing that is not, which is a contrast you see across the state.
For anything going to an oil facility, use the address the operator publishes. For anything going to a community, name the community and the nearest office.
If Your Address Is New or Unlisted
If your address did not exist ten years ago, expect the code to lag behind it. 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 Bayelsa 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 Bayelsa State
Boxes are held at a specific branch rather than at a street, which is why the branch name is not optional when you write one out. 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 Yenagoa Main Post Office 560001 Yenagoa Nigeria
Two practical notes. A box address is often more reliable than a street address in Bayelsa 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 Bayelsa State That Cannot Be Right
We tested the Bayelsa State tables that circulate online for internal contradictions, meaning two local governments published with ranges that share the same numbers. Bayelsa 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 Bayelsa 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 Bayelsa 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 Bayelsa State
Knowing the chain explains why the first three digits matter more than the last three. A letter posted anywhere in Bayelsa 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 5 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 Bayelsa 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 560001 is a safe fallback and a random six digits is not.
How to Write a Bayelsa State Address
A Bayelsa address outside Yenagoa should name the community and the nearest town with an office, because the road network reaches only part of the state.
The order NIPOST expects runs from the specific to the general, with the code on the same line as the town:
Mr P. Ebiye 8 Mbiama Yenagoa Road Yenagoa 560001 Bayelsa 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 5
Bayelsa 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 Bayelsa State.
| State | Prefix |
|---|---|
| Rivers | 500 |
| Akwa Ibom | 520 |
| Cross River | 540 |
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 560001, the Yenagoa head office code, which routes correctly across the state.
What to Enter on a Form
Type 560001 if you are in or near Yenagoa 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
From 1 October 2026 Nigeria moves to a new 11 character postcode that identifies a single building rather than a sorting district. Bayelsa may be the state where a building level code is hardest to implement and most valuable once it exists, because nothing in the current system distinguishes one creek community from the next.

Conclusion
Use 560001. Outside the Yenagoa road corridor, name the community and the nearest town office, add a phone number, and treat the code as the instruction that gets your item to the right riverbank rather than the right door.
