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 NIN date of birth can be corrected from the UK through NIMC's self-service portal, but only once, and only with National Population Commission evidence: an NPC birth certificate if you were born after 1992, or a digitised NPC attestation if earlier. NIMC's February 2026 charter lists ₦28,574 for the change and up to two weeks where the difference is more than five years.
Why it matters more than other errors
Your date of birth is one of the two things the Nigeria Immigration Service portal checks first when you apply to renew a passport: it verifies your NIN and date of birth together. If the NIN says 1984 and your passport says 1986, the renewal stops. Because NIMC allows only one date of birth change, it is also the error you most need to get right first time.
The rules
- Once only. NIMC's diaspora facts sheet says a date of birth change is allowed once in a lifetime and needs approval.
- NPC evidence. NIMC's self-service page asks for a National Population Commission certificate number and an upload of the certificate. If you were born before 1992, that is a digitised NPC attestation of age; if after, an NPC birth certificate.
- Adults 18 and over. NIMC's adult modification page lists an NPC attestation letter as the supporting document for a date of birth change.
- Time. NIMC's charter gives two weeks for a date of birth change where the difference is more than five years, and 48 to 72 hours for most self-service changes.
Getting NPC evidence from the UK
NIMC says the NPC attestation can be obtained online through the NPC's site, nationalpopulation.gov.ng. In July 2026 the NPC moved birth registration to a digital platform. If your birth was never registered with the NPC, start there before you touch the NIN. Have to hand:
- any old document that shows your real date of birth (a hospital record, baptismal card or early school record);
- your Nigerian passport, current or expired;
- a parent's details, because NPC records are linked to parents.
Fees
| Item | Fee | Source |
|---|---|---|
| Date of birth change (self-service or in Nigeria) | ₦28,574 | NIMC Service Charter, Feb 2026 |
| Date of birth change through a diaspora partner, outside Africa | $35 (older figure) | NIMC diaspora facts sheet, Apr 2023 |
The partner figure is from 2023, before NIMC's 2025 fee review, and NIMC has not published a newer outside-Africa date of birth fee that we could find. Ask the partner for its current fee in writing and pay only what the invoice shows.
Steps from the UK
- Get your NPC certificate or attestation, and check every detail on it.
- Go to selfservicemodification.nimc.gov.ng, verify your NIN and log in with the code sent to your linked phone.
- Choose date of birth, pay online and enter the NPC certificate number.
- Upload the NPC document and keep the transaction slip.
- Wait for the email with the new slip. If nothing comes after two weeks, use NIMC's complaints portal or nimcmodification@nimc.gov.ng with your reference.
- Only then start the passport correction or renewal.
If the portal rejects you, a NIMC-licensed diaspora partner can do it in person; see our guide to questions to ask a UK NIN centre about fees. For the Nigeria-side detail on all NIN corrections, see correcting NIN details.
Common situations
An age declaration made years ago
Many Nigerians born before 1992 have no birth certificate and used a sworn declaration of age for school, a first passport or a job. The date on that declaration may not match what your family now says. NIMC accepts the NPC attestation, not the old declaration, so the NPC document is what counts. If the NPC record repeats the old date, the NIN will follow it.
A UK record shows a different date
Your UK records, including any eVisa, follow the passport you used when you applied. If the Nigerian passport changes date after a NIN correction, GOV.UK asks eVisa holders to update their UKVI account when their passport or personal details change, and a change of date of birth needs an identity document that proves it. Plan the order: NIN, then Nigerian passport, then UK records.
A one-digit typing error
Even a slip such as 12 typed as 21 counts as a date of birth change, with the same fee and the same once-only rule. There is no cheaper "typo" route on the NIMC pages we read.
If the wrong date is on your passport instead
Sometimes the NIN is right and the passport is wrong. Then you do not change the NIN at all: you apply to NIS for a correction of data on the passport. Our guide to NIN and passport mismatches explains how to decide which record to fix.
Where Pryme fits
Banks read your date of birth from your BVN and NIN, so a correction usually has to reach your Nigerian accounts too. A Pryme account is opened from the UK with the identity details you give, so it helps to finish the NIN correction first.
