Candidates who have lost access to both their registered GSM number and email address can select the “Both” option during the process.
Such candidates should have:
- A new active GSM number.

- Their JAMB profile details or Profile Code.
They should then make the required payment and visit a designated JAMB CBT centre to complete the verification and update process.

If you can still access your registered email address but have lost access to your JAMB-registered GSM number, select “GSM only” during the service process.
Enter your new GSM number and complete the required biometric verification and Court Affidavit upload.
