HOW-TO

How to Update or Correct Your BVN Details

Correcting a name, date of birth or phone number on your BVN is done at your bank branch, under CBN and NIBSS rules, with the right documents.

Step by step

1. Identify exactly what is wrongConfirm which field is incorrect (name spelling, date of birth, gender, phone number or address). Fixing the wrong field wastes a trip, so check your current record first.
2. Gather supporting documentsTake documents that support the change. Depending on the field this may include a valid government ID, a birth certificate or declaration of age, and for name changes a sworn affidavit or marriage certificate. Ask your bank for its exact current list before you go.
3. Visit your bank branch in personGo to a branch of the bank where you are enrolled and request a BVN modification. This is done face to face; there is no legitimate app or website where you edit BVN data yourself.
4. Complete the bank's modification requestFill the bank's BVN modification/update form and submit your documents. The bank verifies you and forwards the request to NIBSS for processing.
5. Follow up and confirmAsk how long processing takes and keep your reference. Once approved, confirm the corrected details show correctly before relying on them for other services.

Why BVN corrections matter

Your Bank Verification Number carries personal details such as your name, date of birth and registered phone number. When these are wrong or out of date, they can trigger account restrictions, failed verifications and problems opening new accounts, especially because regulators now expect your BVN and NIN details to match. Correcting the record is therefore worth doing properly. If you first need to find or confirm your number, see how to check your BVN.

There is no self-service BVN portal

This is the single most important point, because it is where scams take root. Neither the CBN nor NIBSS provides a public website or app where you log in and edit your own BVN data. All modifications go through a bank branch, where staff verify you in person and submit the change into the NIBSS system on your behalf. Any site or ‘agent’ claiming to change your BVN remotely is not legitimate.

What to bring

The documents you need depend on the field you are correcting. A phone-number or address change is usually lighter on paperwork than a name or date-of-birth change, which typically needs stronger evidence such as a sworn affidavit, a marriage certificate or a birth certificate, alongside a valid government ID. Because banks apply the rules slightly differently and requirements change, call ahead or ask at the branch for the current checklist so you do not make a second trip.

The phone-number rule has changed

Updating the phone number tied to your BVN used to be routine, but the CBN has tightened it to curb SIM-swap fraud. As of 2026, reporting indicates phone-number updates are limited to once in a lifetime under the revised BVN framework. Treat the exact limit as time-sensitive and confirm it with your bank before you apply, since regulatory details can be revised. Keeping the linked number current also matters for other services, as explained in how to link NIN to your phone number.

After you apply

Once the branch submits your request to NIBSS, processing takes time. Keep your reference, and once it clears, verify the corrected details before relying on them elsewhere, including when you check which accounts are linked to your BVN. Throughout the process, remember that no legitimate step requires your OTP or PIN; the warning signs are set out in common NIN and BVN scams.
