Nigeria’s Next Address Layer

7 min read

Ask a Lagos dispatch rider how he finds a customer, and he won’t give you an address. He’ll give you a chain of things that happen to be standing there today. The pharmacy opposite the keke park, past the market. The church that changed its name last year. He’ll probably call twice on the way and sometimes three times. If the customer’s network drops or the pharmacy shuts, the chain breaks and the parcel goes back on the shelf.

The Nigerian Postal Service (NIPOST), puts the cost of misdeliveries from poor addressing at between ₦50 billion and ₦80 billion a year, an estimated $37.65m and $60.24m respectively. That figure comes from the agency, but anyone who has run last-mile delivery in Lagos or Abuja will find it easy to believe.

The postcode NIPOST plans to launch on 1 October is a unique 11-character code for each addressable building. It’s also the latest in a long line. Nigeria began a national addressing push in 2009 under President Umaru Yar’Adua, and it stalled. There was a what3words partnership in 2017, an address verification system in 2018, SIM-card address checks in 2020, an agreement with the National Population Commission in 2022 and a pilot in 2023. Each was announced as the fix. The question for this one is what’s changed, and whether the answer is more than a better code.

What’s Being Switched On

Each code has 11 characters in five parts, running from broad to narrow: state, local government area, district, area and building. NIPOST’s example is FC 02 A09 DB 09. Nothing is replaced. The six-digit postcode in use since 1986 stays, and nobody has to stop giving directions in words. The new code is for software.

The launch is less complete than the date suggests. NIPOST expects to have covered more than 90% of the country by 1 October and to finish all 36 states and the FCT by December 2026, but officials say the areas live on day one will only be confirmed at launch. The developer portal that businesses need is still being finalised. Until it is, NIPOST is collecting expressions of interest from startups, enterprises and government agencies.

The Communications Ministry sees the digital economy as three layers. Identity says who a person is, payments say what value is moving, and the postcode says where. Postmaster General Tola Odeyemi describes the goal as a complete “who and where” identity framework, with each postcode retrievable through a person’s National Identification Number (NIN).

The state and the banks hear this differently. The state hears a way to plan services, send ambulances to the right gate and find people it has never managed to count. Banks hear a possible answer to an old problem, since lenders struggle to verify where a customer lives. Odeyemi has argued that a verified postcode tied to a NIN could help with that.

Under the approved framework, the National Identity Management Commission verifies the addresses of individuals and the Corporate Affairs Commission verifies those of businesses, while NIPOST goes on managing the postcodes. The body that issues the code is not the one that confirms who lives behind it. And a postcode only says where a building is. It can’t tell a bank whether the person at the door lives there, owns the place or can repay a loan.

Ghana’s Version So Far

Ghana is the nearest test case. GhanaPostGPS launched in 2017 and turns the coordinates of a phone into an alphanumeric code. The government has built it into other processes too, and people applying for a Ghana Card are asked for a digital address.

In 2023 a team led by Stephen Leonard Mensah studied how GhanaPostGPS was working in three suburban communities in Accra. The system itself was struggling, with operational problems and government agencies that weren’t using it, but residents saw the benefits. A companion study by some of the same authors surveyed 999 people and found that about 68% of property owners were likely to use it, against 32% of renters. The researchers also found that the app would generate an address anywhere in Accra whether or not a property stood there. More than 2 million of Ghana’s 10 million-plus properties are structures such as metal containers and kiosks. Lagos has plenty of kiosks too, and what counts as an addressable building in Nigeria’s markets and informal settlements is something NIPOST hasn’t answered in public.

What This Means For Business

Logistics and e-commerce companies stand to gain the most, as long as the code stays out of sight. If a checkout page lets a customer type a street name and quietly returns the code behind the scenes, failed deliveries should fall. If customers are told to look up a code on a government website first, most won’t bother. Which of those happens depends on what the developer portal lets companies build.

Banks and fintechs face a quieter change. NIPOST’s published terms cover lookup, validation, standardisation, geospatial services, bulk processing and application programming interfaces, which is a toolkit for checking addresses at scale. The first gain is probably cheaper verification of customers a bank could already assess. Lending to people it can’t reach today is a different matter, because a location doesn’t show that someone can repay, and the bank would need a regulator willing to accept the code as part of the case. That regulator is the Central Bank of Nigeria, not the postal service. A bank can wire the code into its systems and still ask for a utility bill if the central bank’s rules haven’t changed.

Startups building location products are in the most awkward position. Google already supplies place identifiers, and local geocoders read Nigerian landmarks and informal areas better than any grid can. A state-owned reference could become the layer they all build on, or a toll gate they all have to pass. Which one it turns out to be will come down to what access costs and how long approval takes. Fair fees and quick sign-off invite small firms to experiment. Slow, expensive access sends them off to build around it. India went the other way with DIGIPIN, a location code covering roughly four-metre squares. The government published the encoding software openly, so any developer can use it without asking permission.

Companies that sell across borders meet a different problem. Ghana’s grid divides the country into five-metre squares, Nigeria’s code runs from state down to building, and the two use different formats. A firm working in both countries could end up maintaining a separate integration for each, which is a real cost for an exporter or a young logistics company. It also sits awkwardly with the African Continental Free Trade Area, which is meant to make it easier for African businesses to trade with one another. An agreed way of exchanging location data would let a company ask the same question in Accra and Lagos and get the answer in the same form.

Who Holds The Data

Tying a building to a person is where the postcode becomes valuable, and where it becomes risky. Postmaster General Tola Odeyemi says the federal government will own the data through the Nigerian Postal Service, with a tiered access model agreed with the Nigeria Data Protection Commission. Some data would be public and some restricted, and the most sensitive would go through agreements or institutions such as the Office of the National Security Adviser.

The design will be tested against a real incident. The data regulator has already had to investigate a website that accessed National Identification Numbers and personal details from the identity database without authorisation. A register of who lives where raises what is at stake if something like that happens again. Every company that links the postcode to its customer records also becomes a keeper of address-linked personal data, with the legal exposure that follows.

Being findable means different things to different people. A property the state can locate is easier to bill than to borrow against. For someone in an informal settlement, the code can be a claim on the city or a demand from it, and the code that sends an ambulance to the right gate will send an assessor to the same one.

Most residents will go on giving directions in words. Who else can read the building behind those words depends on how the access rules Odeyemi describes work in practice.

What We’re Watching

• The developer portal’s terms, including pricing, rate limits and the tiered access rules, will decide whether companies build on the postcode or around it, and whether they can integrate it without inheriting a liability.
• A code that lenders still have to back up with paperwork saves nobody any time. This will depend on guidance from the Central Bank of Nigeria and how fast the National Identity Management Commission and the Corporate Affairs Commission can verify addresses.
• NIPOST says more than 90% of the country will be mapped by launch day. Thin or wrong maps in rural areas and dense informal settlements would cost trust early, and the December deadline for full coverage will show how much of that figure holds up on the ground.
