AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
A NUBAN (Nigeria Uniform Bank Account Number) is the standard 10-digit account number every Nigerian deposit-taking institution gives its customers under CBN rules: nine serial digits plus a check digit. Canadian transfer apps ask for it because it is how a Nigerian account is identified; they also ask for the bank, because the check digit is calculated with the bank's code, so the same 10 digits only make sense with the right bank.
Where the NUBAN comes from
The Central Bank of Nigeria introduced uniform account numbering so that every account in the country follows one format. Its revised NUBAN standards, a circular dated 9 March 2020 (effective 20 April 2020, with full compliance by 15 March 2021), apply to all deposit-taking institutions: commercial banks, microfinance banks, mortgage banks and others. The customer sees a 10-digit number, but the full NUBAN is 16 digits long.
- Institution code (6 digits)
- For a deposit money bank, its 3-digit CBN code with three leading zeros; for other financial institutions, a 5-digit code with a leading 9
- Serial number (9 digits)
- The account's own number within that institution
- Check digit (1 digit)
- Calculated from the other 15 digits
- Customer-facing number
- Serial number plus check digit: 10 digits
So when someone in Lagos tells you their account number, they are giving you the last 10 digits. The institution code is supplied by the app when you pick the bank from its list.
How the check digit works
The circular sets the method: multiply the 15 digits (institution code then serial number) by the weights 3, 7, 3 repeated, add the results, take the remainder after dividing by 10, and subtract it from 10. A result of 10 becomes 0.
Change one digit and the check digit changes. Swap the last two serial digits (000004512) and the same sum gives a check digit of 4, so 0000045210 typed as 0000045120 fails the check. This is why an app can sometimes tell you a number is invalid before it contacts anyone in Nigeria. The method has a limit: swapping two neighbouring digits that carry the same weight, such as the third and fourth digits of the account number, leaves the sum unchanged and is not caught. For the full algorithm, see our Nigeria library's NUBAN check digit guide.
Why apps ask for the bank as well
- The check digit depends on the bank code. A number valid at one bank can be invalid, or valid for someone else, at another.
- The payout is routed by bank. The provider needs to know which institution to credit.
- Name checks. Some apps show the account holder's name after you enter the number and bank. Where yours does, compare it with the name your recipient gave you.
What the check digit cannot do
A valid NUBAN only proves the number is well formed for that bank. It does not prove the account belongs to the person you mean to pay. A typo that happens to produce another valid number, or a fraudster's account given to you as a relative's, passes the check. Taptap Send's Nigeria page, for example, says money sent to a wrong number or account cannot be reversed. Read the number back, compare names, and send a small amount first to a new recipient. Our guide to a transfer to the wrong account covers recovery.
Microfinance banks and fintech accounts
The NUBAN standard covers all deposit-taking institutions, not just the big commercial banks. The circular gives other financial institutions, such as microfinance banks, a 5-digit code with a leading 9 in place of the commercial-bank format. For a sender in Canada this has two consequences:
- The bank must be on the app's list. Many Nigerians now hold accounts with microfinance banks behind consumer apps. If the institution is not in your transfer app's bank list, the app cannot route to it, however valid the number.
- Pick the exact institution. Brand names and licensed institution names can differ. Ask the recipient which institution their account statement names, and choose that.
If the app's list does not include it, ask the recipient for an account at an institution that is listed rather than guessing a similar name.
NUBAN, BVN and other numbers people confuse
| Number | What it identifies | Do you need it to send? |
|---|---|---|
| NUBAN (10 digits) | A bank account | Yes |
| BVN (11 digits) | A person across all their bank accounts | No |
| SWIFT/BIC (8 or 11 characters) | A bank, for international wires | Only for a wire |
| Phone number | A contact, or a wallet at some providers | Sometimes |
The recipient can check the name their BVN holds by dialling *565*1#, which NIBSS says shows the registered name for ₦20. That helps match the account name, but you do not need the BVN itself. See details a Nigerian receiver gives a Canadian sender and name mismatches.
Where Pryme fits
Pryme's Send pays Nigerian accounts by NUBAN and bank from a naira balance in an account you can open from Canada. The app shows the rate and the fee before you approve.
Questions people ask
What is a NUBAN number?
The Nigeria Uniform Bank Account Number: the standard 10-digit account number set by the CBN for all deposit-taking institutions, made of a 9-digit serial number and a check digit.
Is NUBAN the same as an account number?
Yes. The 10-digit account number Nigerians give you is the customer-facing part of the NUBAN.
Why does the app say my Nigerian account number is invalid?
The check digit may not match for the bank you selected. Check that the number has 10 digits and that the bank is correct.
Is a NUBAN the same as an IBAN?
No. Nigeria uses the 10-digit NUBAN with the bank chosen separately; it is not an IBAN.
