The Joint Admissions and Matriculation Board (JAMB) has introduced a new process allowing candidates who have genuinely lost access to their registered phone number or email address to update their details.
The new arrangement is aimed at helping candidates who can no longer access the GSM number or email address originally linked to their JAMB profile.
According to the update, the service commenced on September 21, 2026 and is available only through designated JAMB Computer-Based Test (CBT) centres, including applicable State Offices.
Who Can Use The Service?
The service is intended for candidates with genuine cases involving the loss of access to their registered:
- GSM/phone number
- Email address
- GSM number and email address
Candidates must have a legitimate reason for requesting the change and will be subjected to identity and biometric verification before the update can be processed.
Where Can Candidates Change Their Details?
JAMB said the service can only be accessed at designated JAMB CBT (PTC/PRC) Centres, including State Offices where applicable.
Candidates are advised not to use unauthorised agents, cybercafés or individuals claiming to have special access to the service.
The controlled process is designed to protect candidates' accounts and prevent unauthorised changes to personal information.
Strict Identity And Biometric Verification
Candidates requesting the update should expect to undergo strict verification.
JAMB's process requires the candidate's identity and biometrics to be verified before the registered GSM number or email address can be changed.
This is particularly important because a phone number or email address linked to a JAMB profile can provide access to important admission-related information and services.
The Service Can Only Be Used Once
One of the major conditions attached to the new service is that it can be accessed only once.
Candidates are therefore advised to make sure that the new phone number and/or email address they provide is correct, active and accessible before submitting the request.
A candidate should not treat the service as an option for repeatedly changing contact details.
What Should Candidates Do?
Candidates who have genuinely lost access to their registered SIM or email should visit a designated JAMB centre and request the service.
Before proceeding, candidates should ensure they have the necessary personal and registration information required for identity verification.
They should also make sure that the new GSM number or email address they intend to register belongs to them and can be accessed whenever required.
JAMB Warns Candidates Against Unauthorised Persons
Candidates should be careful when seeking assistance with their JAMB records.
Because the process involves sensitive personal and biometric information, candidates should deal directly with designated JAMB centres.
They should avoid giving their JAMB login details, OTPs or other sensitive information to individuals claiming they can change the details remotely.
Why This Update Matters
The change is particularly important for candidates who have lost their SIM cards, had their phone numbers permanently disconnected or can no longer access the email address originally used during JAMB registration.
Without access to the registered contact details, candidates may experience difficulties receiving or completing certain JAMB-related processes.
The new arrangement provides a controlled channel through which eligible candidates can update their information while maintaining identity and biometric checks.
Important Points To Remember
Candidates should keep the following in mind:
- The service commenced on September 21, 2026.
- It is for candidates with genuine cases of lost access to their registered GSM number and/or email.
- The service is available only at designated JAMB CBT (PTC/PRC) Centres and applicable State Offices.
- Identity and biometric verification are required.
- The service can be accessed only once.
- Candidates should carefully confirm their new contact details before submission.
- Avoid unauthorised agents and unofficial channels.
Candidates who still have access to their registered phone number and email should not attempt to use the service unnecessarily.
