JAMB has reopened its National Identification Number alignment service.
Candidates whose exam records do not match their NIMC data can now try to fix the gaps.
The reopening is a one time chance.
Approval is not automatic, and applications will be checked before any decision is made.
Candidates should first get any errors corrected by NIMC, then apply to align their details with their JAMB records.
Mismatches may involve names, dates of birth and other biodata.
JAMB advises applicants to check every field and make all corrections in one submission.
It also warns against rushing or sending incomplete information.
A video guide called JAMB Explained, posted on its online handle, sets out the eligible fields, the steps and the required documents.
Candidates should use only official JAMB channels and avoid third party agents.
The aim is to make the personal records used for university and polytechnic admissions more accurate.
