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
Under the CBN's 2021 BVN framework, a request to update BVN records should be resolved within five working days of all supporting documents being submitted, and the customer must be notified once the update is done. Delays usually come from incomplete documents, name changes that need NFIU clearance, or the one-time limits on date-of-birth and phone changes.
The rule: five working days after complete documents
Section 1.14 of the CBN's Revised Regulatory Framework for BVN Operations and Watch-List (October 2021) deals with updating BVN records. It says resolution shall be within five working days after all documents are submitted, and that customers shall be notified after the update. The clock starts when your file is complete, not when you first walk in, so missing documents are the main cause of delay.
What each type of change needs
| Change | Limit | Documents or extra step |
|---|---|---|
| Date of birth | Once | Supporting documents, such as birth certificate or ID showing the correct date |
| Name: marriage, divorce, religion | No limit stated | Supporting documents, such as marriage certificate, decree, newspaper publication or affidavit as the bank asks |
| Name: minor spelling error | No limit stated | Official ID showing the correct name |
| Name: totally or partially different | No limit stated | Documents, and the case is reported to the NFIU, which issues clearance for totally different names |
| Phone number | Once (2026 addendum) | ID and the new line; the bank verifies you |
The phone number limit comes from a March 2026 addendum, reported by ThisDay, which says amendments to phone numbers linked to a BVN are allowed only once. The framework also requires the name on your BVN to match across all your accounts in the industry. For each change in detail, see BVN correction rules, changing the phone number on a BVN and changing your BVN name after marriage.
Why a different-name request takes longer
Where the new name is wholly or partly different from the old one, the framework treats the change as one the bank must report to the NFIU as a suspicious act. A totally different name needs NFIU clearance before it can go through. That step is outside the bank's five-day control, so expect a longer wait and ask the bank to tell you when the case was referred.
Why requests stall
- Documents that do not agree. If your marriage certificate, NIN and ID show different spellings, the bank will usually ask you to fix the source document first, for example by correcting the NIN with NIMC.
- A once-only change already used. If your date of birth or phone number was changed before, the bank may say it cannot change it again under the framework and the 2026 addendum.
- Missing account-level updates. The framework requires your name to match across all accounts in the industry, so a change may need follow-up at your other banks.
- Closure with large balances. Where account closure is involved, the framework requires NFIU clearance before balances above ₦10 million are transferred, which adds time.
- Branch backlog. Requests sent to a central team can sit unprocessed; a written reference helps you chase them.
How the bank confirms the update
The framework says the customer must be notified after the update. In practice, banks confirm by SMS or email and the change shows on your profile. You can check yourself:
- Dial *565*1# and enter your BVN to see the name now on the record (₦20 per NIBSS, as at Nov 2025).
- Try a verification at a second bank or app; if the new name or date now matches, the update has gone through.
- Ask the bank for the request reference and the date the file was marked complete.
How to track and escalate a delay
- Get a reference number when you submit, and a list of documents the bank holds.
- Count five working days from the date the bank confirms your documents are complete.
- Chase in writing by email to the bank's complaints address, quoting the reference and the five-day rule in section 1.14 of the framework.
- Escalate internally to the bank's complaints or customer experience unit if there is no answer.
- Escalate to the CBN. The framework names the CBN Consumer Protection Department as the body that handles BVN complaints. TechCabal's 2026 bank contacts guide gives the CBN route as cpd@cbn.gov.ng or the CBN online complaint form, after the bank has had about two weeks to resolve it.
Worked example
Example only: Ada submits a name change after marriage on Monday 2 November with her marriage certificate and ID. The bank asks on Wednesday 4 November for a sworn affidavit, which she brings on Thursday 5 November. The file is complete on 5 November, so five working days ends on Thursday 12 November. If she has not been notified by then, she emails the bank's complaints desk the same day with her reference.
Keep copies of everything you hand over, and photograph the bank's acknowledgement. If you later escalate to the CBN, a complaint that shows the submission date, the reference and the date the file was confirmed complete is much easier to act on than one that relies on memory.
Questions people ask
How many days does BVN update take?
The CBN framework says five working days after all supporting documents are submitted. Name changes that need NFIU clearance can take longer.
How do I know my BVN update is successful?
The bank must notify you. You can also dial *565*1#, enter your BVN and check the name shown (₦20 as at Nov 2025).
Can I change my BVN date of birth twice?
No. The framework allows a date-of-birth correction once, with supporting documents.
Where do I report a delayed BVN modification?
First the bank's complaints unit, then the CBN Consumer Protection Department, which handles BVN complaints.
