How to Change Phone Number on JAMB Portal at CBT Centres

Candidates can change their phone number on the JAMB portal at accredited CBT centres by visiting the centre with their National Identification Number slip and examination printout, completing a data correction application, paying the statutory fee, and verifying their identity through biometric fingerprint scanning.

A candidate’s registered mobile telephone number is a vital authentication credential within the Joint Admissions and Matriculation Board ecosystem. Through this registered phone number, candidates receive profile verification codes, check examination scores via SMS shortcodes, and execute admissions decisions on the Central Admissions Processing System. However, candidates frequently experience stolen mobile phones, network SIM card deactivations, or discover that an errant cyber cafe operator inputted a third-party telephone number during initial registration. Because phone numbers are directly tied to profile security and admissions integrity, changing a phone number cannot be done on personal computers; it strictly requires physical biometric authentication at an accredited CBT centre or official board office.

To change a registered phone number, the candidate gathers their original National Identification Number (NIN) slip, their original UTME examination registration slip, and a newly activated, registered SIM card bearing their legal name. The candidate visits an accredited JAMB Computer-Based Test centre or official state zonal office. The centre operator accesses the JAMB eFacility administrative portal and selects Candidate Phone Number Modification from the data correction menu.

The candidate enters their registration number, and the operator inputs the new mobile telephone number. To prevent fraudulent profile tampering, the candidate must place their thumbs on the optical fingerprint scanner. The central server matches the live biometric scan against the fingerprint template captured during original UTME enrollment. Once biometric validation is successful, the candidate pays the statutory administrative fee via Remita. The central server updates the candidate’s database record immediately and transmits a confirmation security code to the new phone number, activating it for all future portal transactions.

The administrative guidelines enforced by the Joint Admissions and Matriculation Board warn candidates that changing phone numbers through unauthorized cyber cafes is impossible and risks profile suspension.

Data security standards monitored by the Standards Organisation of Nigeria ensure that biometric modifications maintain strict forensic integrity across all accredited testing centres.

Updating an inaccessible phone number promptly ensures that prospective undergraduates never miss critical university admission offers on CAPS.

Candidates should safeguard their newly registered phone line to maintain uninterrupted access to national board communication channels throughout their undergraduate studies.

Completing these security steps guarantees that candidates retain seamless access to their admission profiles, facilitating a smooth transition into tertiary education.

Staying attentive to official communication channels ensures candidates receive time-sensitive updates regarding matriculation numbers and admission screening dates.
