The Joint Admissions and Matriculation Board (JAMB) has introduced a controlled process for candidates who have genuinely lost access to their registered phone numbers or email addresses to update their details.

The board announced the development on Monday through its official X account, stating that the service commenced on September 21, 2026.

According to JAMB, the service is available only at designated Computer-Based Test (CBT) centres, including state offices where applicable.

The board said the measure was specifically designed for candidates with genuine cases involving the loss of access to their registered GSM numbers or email addresses.

It added that candidates seeking to use the service would be required to undergo strict identity and biometric verification before any update could be effected.

“Please note: The service can be accessed only once and is subject to strict identity and biometric verification,” JAMB stated.

The board also advised candidates to visit only designated JAMB centres and warned them against engaging unauthorised individuals or channels for the update.

“For your security, use only designated JAMB centres and avoid unauthorised persons or channels,” it said.

JAMB explained that the initiative was part of its JCARE and JAMB Updates programmes.

Under the revised policy, eligible candidates can request an update of their registered GSM number, email address, or both, provided they meet the verification requirements.

However, the board stressed that the service can only be accessed once and remains subject to successful identity and biometric verification.
