How to Change Phone Number Linked to JAMB Profile on eFacility Portal

Candidates can change the phone number linked to their JAMB profile by visiting an official board state or zonal office with their National Identification Number slip, a sworn affidavit of SIM card loss, and undergoing live biometric verification to update their telecommunication contact records.

The mobile phone number registered during initial National Identification Number profile creation serves as the primary cryptographic link binding candidate profiles to central databases. All official notifications—including profile codes, e-PIN confirmation receipts, Computer-Based Test examination schedules, password reset tokens, and admission status alerts—are dispatched through this verified mobile connection. However, candidates occasionally experience phone theft, SIM card deactivation by telecommunication operators due to prolonged inactivity, or physical card damage. Understanding the official protocol for updating contact records prevents candidates from being permanently locked out of their candidate profiles.

To prevent unauthorized account hijacking and fraudulent course modifications, the central examination board strictly prohibits candidates from changing registered mobile phone numbers through commercial cybercafes or unverified mobile applications. The alteration must be executed in person at an official state zonal office of the examination board. The candidate must assemble a comprehensive verification dossier comprising their original National Identification Number slip, an authentic Sworn Affidavit of SIM Card Loss deposed at a High Court of Justice, an official Police Incident Report certifying the loss or theft of the mobile telephone, and valid secondary school identification documents.

At the board office, an authorized technical officer verifies the candidate’s identity through live biometric fingerprint scanning. Once the optical fingerprint reader confirms that the candidate’s live biometric characteristics match the stored examination registration profile, the system unlocks the contact records. The officer inputs the candidate’s newly registered GSM phone number, transmits a validation confirmation code to the new handset, and commits the updated telephone number to the permanent candidate ledger. The newly registered phone number immediately becomes active for all subsequent SMS inquiries and eFacility password resets.

The Joint Admissions and Matriculation Board cautions candidates never to use phone numbers belonging to cybercafe agents, as losing access to the registered line severely compromises admission management.

Information security standards upheld by the Standards Organisation of Nigeria ensure that electronic profile databases maintain end-to-end encryption, protecting candidate personal data against unauthorized interception or breach.

Candidates should also save the official transaction receipt provided by the board office after updating their telephone number. In the unlikely event of system delays in activating the new number on the eFacility web portal, the transaction reference allows board customer service personnel to verify the change and ensure instant synchronization across all connected databases.

Updating a lost phone number through official channels ensures that prospective undergraduates maintain uninterrupted communication with national admissions repositories throughout their higher education journey.
