The Joint Admissions and Matriculation Board has announced a strict no change policy for candidate biodata, warning that once registration is completed, subsequent data changes will not be effected for the 2026 admission cycle.

"Once a candidate completes 2026 registration with biodata supplied by NIMC, subsequent changes of biodata would not be effected by JAMB for the 2026 admission," JAMB stated, adding in capitals: "NO CHANGE WILL BE TOLERATED."

For candidates requiring updates due to legitimate NIMC corrections, JAMB outlined a complex process called "RE-QUERY" using "TEMPL 007" during registration. However, replaced data will be tracked and "ever reflected as footnote on the candidates profiles and all slips," permanently flagging any changes made.

The policy essentially forces candidates to ensure NIMC data is completely accurate before registration. "Candidates should ensure their personal details, including National Identification Number (NIN), email, and A-Level results, are accurate before generating a profile code," JAMB stated.

For candidates discovering errors in NIMC data, the solution is visiting NIMC directly before JAMB registration. "Candidates should make all necessary corrections with NIMC early and confirm that the changes have been reflected on their portal before registration (for instance, name, date of birth, gender, and state of origin)," JAMB advised.

The measure appears designed to prevent candidates from manipulating biodata after registration to gain unfair advantages or cover discrepancies. By making changes extremely difficult and permanently flagged, JAMB is forcing candidates to get their data right from the start.

Biodata errors commonly requiring correction include misspelled names, incorrect dates of birth, wrong gender designation, and incorrect state of origin. Candidates whose NIN data doesn't match birth certificates or school certificates must resolve discrepancies before JAMB registration, not after.

For candidates with legitimate name changes due to marriage or legal reasons, they must first update at NIMC, then ensure updates are reflected in the system before JAMB registration.

JAMB's advice to make corrections early suggests starting several weeks before the January 27 registration date. NIMC offices can be overwhelmed, and system updates may not be instantaneous. Candidates waiting until late January may find themselves unable to register by the February 28 deadline.

Candidates should: obtain NIMC slip several weeks before registration; compare NIMC data with other official documents; visit NIMC immediately if errors exist; follow up to confirm changes are reflected; only after confirmation should they generate their JAMB profile code.
