Quick answer
If your bank asks you to link or update BVN/NIN details, use the bank’s official app, branch, website, or verified customer-care channel. Do not submit BVN, NIN, OTP, PIN, or card details through random links.
Safe update checklist
- Confirm the request through your bank’s official channels.
- Use only official bank links or visit a branch.
- Do not share OTPs or passwords.
- Keep receipts or confirmation screenshots.
- If your account is restricted, ask the bank exactly what document is missing.
Common reasons for issues
Name mismatch, date-of-birth mismatch, multiple phone numbers, old account records, or missing NIN/BVN fields can cause delays. Fixing identity mismatch may require bank and identity-management processes.
