Edo State postal codes begin with 30 or 31. Benin City head office is 300001, and the state’s codes run up to 313111.
300001 anchors postal region 3, covering Edo, Delta, Ondo and Ekiti. Benin City holds it as the historic and administrative centre of the old Mid West, and the region was numbered outward from there.

Reading a Edo State Code
Take 300001, the Benin City head office code. The first digit, 3, puts the address in postal region 3. The first three digits, 300, 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 Edo State code is built the same way, which gives you a quick test. If someone hands you a code for an address in Edo State and it does not begin with 30, it is not a Edo State code.
Dispatch Districts in Edo State
The 300 and 310 through 313 blocks divide the state between Benin City and everywhere else. Benin dominates, holding the bulk of the state’s post, while the higher blocks reach Auchi and the Edo North axis, and Ekpoma and the Esan local governments in the centre.
| Dispatch prefix | Codes it issues |
|---|---|
| 300 | 300001 to 300999 |
| 301 | 301001 to 301999 |
| 302 | 302001 to 302999 |
| 310 | 310001 to 310999 |
| 311 | 311001 to 311999 |
| 312 | 312001 to 312999 |
| 313 | 313001 to 313999 |
The 18 Local Government Areas in Edo State
Edo has 18 local government areas, grouped informally into Edo South around Benin City, Edo Central around Ekpoma and Edo North around Auchi. Those three groupings map onto the postal geography better than the individual local governments do.
| Akoko-Edo | Egor | Esan Central |
| Esan North-East | Esan South-East | Esan West |
| Etsako Central | Etsako East | Etsako West |
| Igueben | Ikpoba Okha | Oredo |
| Orhionmwon | Ovia North-East | Ovia South-West |
| Owan East | Owan West | Uhunmwonde |
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 Edo State contradict each other and sometimes contradict themselves.
The Ring Road City
Benin City has the most legible street layout of any old city in southern Nigeria. Roads radiate outward from the Ring Road at the centre, and the major arteries, Sapele Road, Akpakpava, Mission Road, Ugbowo Lagos Road, are the reference points every address uses. Because the layout is radial rather than gridded, an address is usually given as a house number on a named road plus the nearest junction.
The practical effect for post is good. Benin addresses resolve reliably on the street name alone, which is not true of most cities its size, and the delivery districts follow the roads rather than cutting across them.
Ekpoma, Auchi and the Northern Axis
Edo Central and Edo North behave differently. Ekpoma is a university town, and Ambrose Alli University generates the institutional post that shapes its delivery districts. Auchi, further north, is the commercial centre for that end of the state and has its own telephone area code, 02057, separate from Benin’s 02053.
Between those towns the settlements are spread out, and a delivery district can cover several communities. Name the town with the post office first, then the community.
Why Edo Codes Get Confused With Delta
Edo and Delta were one state until 1991 and still share a postal region, sitting at 300 and 320 respectively. Older documents, and plenty of current websites, file towns under the wrong one of the pair. Anywhere along the boundary near Agbor and Ewohimi, check the state before trusting a published code.
Post Office Boxes and Private Mail Bags in Edo 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 Benin City Main Post Office 300001 Benin City Nigeria
Two practical notes. A box address is often more reliable than a street address in Edo 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 Edo State That Cannot Be Right
We compared the Edo State code tables that circulate online against themselves. A code belongs to one delivery district, so if two local governments are published with ranges that share numbers, at least one of the two is invented. Edo State fails that test in 2 visible places, and here are the clearest.
Ranges that swallow their neighbours:
- Egor at 300103 to 300103 overlaps Oredo at 300001 to 300283.
- Ikpoba Okha at 300104 to 300105 overlaps Oredo at 300001 to 300283.
None of this means the numbers themselves are fictional. They sit in the correct blocks for Edo State. What is fictional is the neat range attached to a local government, because that mapping was estimated by whoever first built the table, and every site that copied it inherited the estimate.
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 Edo 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 Edo State
Knowing the chain explains why the first three digits matter more than the last three. A letter posted anywhere in Edo 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 3 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 Edo 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 300001 is a safe fallback and a random six digits is not.
How to Write a Edo State Address
Benin City is built as a series of ring roads radiating from the Oba’s palace, so addresses there are given by road and by which ring you are on.
The order NIPOST expects runs from the specific to the general, with the code on the same line as the town:
Mr O. Igbinedion 21 Sapele Road Benin City 300001 Edo 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 3
Edo 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 Edo State.
| State | Prefix |
|---|---|
| Delta | 320 |
| Ondo | 340 |
| Ekiti | 360 |
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 300001, the Benin City head office code, which routes correctly across the state.
What to Enter on a Form
Type 300001 if you are in or near Benin City 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. Benin City’s radial layout translates cleanly into building level codes, so Edo should be one of the smoother states to migrate.

Frequently Asked Questions
What is the zip code for Benin City?
Benin City head office is 300001. All Edo codes begin 30 or 31, with the state range running to 313111.
Why does Edo hold the 300001 code?
Because Benin City was the centre of the old Mid West region. Postal region 3 was numbered outward from it, which is why Delta, Ondo and Ekiti codes all begin with 3.
What is the postal code for Ekpoma?
Ekpoma is served from the higher Edo blocks. It is a university town, so campus post is addressed to the department and campus while the town code covers everything else.
What is the postal code for Auchi?
Auchi sits in the northern block and is the commercial centre for Edo North. Its telephone area code is 02057, which is a separate system from the postal code.
How many local governments are in Edo State?
Eighteen, grouped informally as Edo South, Edo Central and Edo North.
Are Edo and Delta postal codes related?
They are neighbours in the numbering, at 300 and 320, because the two states were one until 1991. That closeness is why border towns are often filed under the wrong state online.
Is the Benin area code the same as the postal code?
No. Benin City’s telephone area code is 02053, changed from 053 in 2023. The postal head office code is 300001.
What code do I use for a village in Edo State?
Use the code of the nearest town with a post office, and name the community in the address. If unsure, 300001 reaches the state.
Summary
Edo codes begin with 30 or 31 and run from 300001 to 313111. Benin City head office, 300001, anchors postal region 3 for the old Mid West. Eighteen local governments split into the Benin dominated south, the Esan centre around Ekpoma and the northern axis around Auchi.
Conclusion
Use 300001 on forms. In Benin City the road name and junction do the work, which is why post there arrives more reliably than in most comparable cities. Outside it, name the town with the post office and treat the code as pointing there.
