How to Change Your Registered Phone Number or Email On JAMB. The Joint Admissions and Matriculation Board (JAMB) has introduced an option that allows candidates who have lost access to their registered GSM number or email address to update those details.
Under the new arrangement, candidates can now request a change to their registered GSM number, email address, or both, provided they can complete the required authentication and verification process.
The service is particularly intended for candidates who can no longer access the SIM card or email account originally linked to their JAMB profile.
The service commenced on Monday, 21 September 2026.
However, candidates should take note of an important restriction: the SIM swap/email change service can only be accessed once. JAMB’s process is therefore not designed for candidates to repeatedly change their registered contact details.
The Board’s procedure also requires candidates to undergo strict authentication before the requested change can be approved. Completing the online steps or paying the prescribed fee does not, by itself, mean that the new GSM number or email address will automatically be approved.

Why JAMB Is Allowing Candidates to Change Their GSM Number or Email
JAMB uses candidates’ registered contact details as part of its candidate identification and communication system.
A candidate who loses access to the phone number or email account attached to their JAMB profile may therefore experience difficulty accessing services that depend on those details.
For example, a candidate may have:
- Lost or damaged the SIM card used during JAMB registration.
- Lost access to the registered GSM number.
- Lost access to the email account originally associated with the JAMB profile.
- Changed their contact details and no longer have access to the old details.
The new service provides a formal process through which eligible candidates can request an update instead of being permanently locked out of their registered contact information.
It is important, however, that candidates understand that this is not an unrestricted profile-editing option. JAMB has specifically indicated that the service can only be used once.
Who Can Use the JAMB SIM Swap or Email Change Service?
The service is intended for candidates who have lost access to their registered SIM or email account.
Candidates who still have access to their registered GSM number and email address should not treat the service as an opportunity to routinely change their details.
The process involves identity verification, and JAMB has indicated that approval is subject to strict authentication.
This means candidates should only initiate the request where there is a genuine need to recover or update their registered contact information.
How to Change Your JAMB Registered GSM Number or Email Address
Candidates who need to use the service should follow the process outlined by JAMB.
Step 1: Log in to JAMB e-Facility
Log in to your JAMB e-Facility account using your existing credentials.
The process can be accessed using your JAMB Registration Number or Profile Code, as indicated in JAMB’s instructions.
Candidates should ensure that they are using their own JAMB details and should avoid giving their login credentials to unauthorised individuals.
Step 2: Select “SIM Swap/eMail Change Payment”
After logging into the JAMB e-Facility, select the option labelled:
“SIM Swap/eMail Change Payment”
Proceed to pay the prescribed fee for the service.
The notice does not state the amount of the prescribed fee in the information provided, so candidates should rely on the amount displayed through the official JAMB payment process rather than paying an amount quoted by an unofficial agent.
Step 3: Visit a Designated JAMB CBT Centre
After payment, proceed to a designated JAMB CBT (PTC/PRC) Centre.
At the centre, candidates will be able to access the SIM Swap/eMail Change Quicklink.
This part of the process is important because the change is tied to candidate authentication and biometric verification.
Step 4: Enter Your Profile Code or Existing GSM Number
At the designated centre, enter either your Profile Code or existing GSM number as required.
Then select:
“Fetch Details”
The system will retrieve the candidate’s relevant details for the next stage of the process.
Step 5: Complete Biometric Verification
The candidate must complete the required biometric verification.
This is one of the safeguards in the process because JAMB is not simply allowing anyone with a candidate’s registration information to change the contact details attached to the account.
Candidates should therefore expect their identity to be verified before the requested change can proceed.
JAMB SIM Swap and Email Change Requires Strict Authentication
One of the most important things candidates should understand is that payment and submission do not automatically guarantee approval.
The requested change is subject to strict authentication before approval.
The authentication process is designed to establish that the person requesting the change is genuinely the candidate associated with the JAMB record.
This is particularly important because a registered GSM number and email address can be connected to access to important admission and examination-related services.
Candidates should therefore provide accurate information and follow the prescribed verification procedure.
A request that cannot satisfy the required authentication should not be assumed to have been approved simply because the candidate has paid the service fee.
Step 6: Select the Service You Need
After completing biometric verification, select the particular service you want.
JAMB provides three options:
- GSM only
- Email only
- Both GSM and email
Select the option that corresponds to your situation.
For example, a candidate who has lost access only to the registered phone number can request a GSM change without necessarily changing the email address.
A candidate who has lost access to both can select the option for both GSM and email.
Step 7: Enter Your New GSM Number and/or Email Address
Enter the new contact details you want associated with your JAMB profile.
Depending on the service selected, this may be:
- A new GSM number;
- A new email address; or
- Both a new GSM number and a new email address.
Candidates should check the details carefully before proceeding because the service is available only once.
This makes it particularly important to avoid entering an incorrect phone number or email address.
Step 8: Upload Your Scanned Court Affidavit
Candidates are also required to upload a scanned Court Affidavit as part of the process.
The affidavit should be prepared and scanned clearly enough for the relevant information to be reviewed.
Candidates should ensure that the document they upload belongs to them and corresponds with the information being provided during the request.
Step 9: Click “Update”
After entering the new details and uploading the required Court Affidavit, click:
“Update”
A confirmation message should appear when the process has been successfully completed.
However, candidates should distinguish between successful submission of a request and approval of the requested change.
Because JAMB requires strict authentication before approval, candidates should follow the status or confirmation provided through the official process and not assume that a change has been approved merely because the update was submitted.
The JAMB Service Can Only Be Used Once
This is perhaps the most important warning in the new arrangement.
The SIM swap/email change service can be accessed only once.
Candidates should therefore not approach the process casually.
Before submitting a request, confirm that:
- You genuinely need to change the registered GSM number or email.
- Your new GSM number is active.
- Your new email address is accessible.
- You have entered the correct new contact details.
- Your Court Affidavit is ready and properly scanned.
- You understand which of the three options you need: GSM only, email only, or both.
A mistake is particularly significant because the service is not presented as an option that candidates can repeatedly use to correct contact details.
Why the Authentication Requirement Matters
Changing the contact information connected to a JAMB profile is different from simply changing a personal preference on an ordinary online account.
The registered GSM number and email can be associated with a candidate’s identity and access to JAMB-related services.
For that reason, JAMB’s process includes authentication steps before approval.
The requirement for biometric verification, together with the submission of a Court Affidavit, provides additional documentation and identity checks around the request.
Candidates should therefore be prepared to personally complete the required process at the designated centre.
Can I Change Only My Phone Number?
Yes.
The JAMB procedure provides a GSM-only option.
If you have lost access to your registered phone number but can still access your registered email address, you can select the GSM-only service.
Can I Change Only My Email Address?
Yes.
The procedure also provides an email-only option.
Candidates who have lost access to the email address connected to their JAMB profile can select the email-only service.
Can I Change Both My Phone Number and Email?
Yes.
Candidates who have lost access to both their registered GSM number and email address can select the Both option.
They will then provide their new GSM number and email address as required.
Do I Need to Go to a JAMB CBT Centre?
Yes, according to the procedure displayed by JAMB.
After paying for the service through JAMB e-Facility, candidates are required to proceed to a designated JAMB CBT (PTC/PRC) Centre and access the SIM Swap/eMail Change Quicklink.
The centre is also where the candidate completes the required biometric verification.
