Candidates can fix the JAMB profile error “NIN Already Used by Another Candidate” by sending the word RESEND via SMS to 55019 or 66019 from the original registered phone number, or by visiting an accredited JAMB state office with their original National Identification Number slip to unlink fraudulent or mismatched profile records.
Encountering the error message “NIN Already Used” or “NIN Linked to Another Profile” when attempting to generate a profile code for the Unified Tertiary Matriculation Examination is a critical technical obstacle. The Joint Admissions and Matriculation Board enforces a strict one-to-one relationship between a candidate’s National Identification Number (NIN) issued by NIMC and their national examination profile code. This error occurs primarily under three common scenarios: the candidate registered for UTME in a previous year using a different phone number, an errant cyber cafe operator mistakenly used the candidate’s NIN to generate a code for another applicant, or there is a demographic mismatch in the NIMC central identity database. Understanding the exact remediation steps ensures candidates resolve profile conflicts before registration closes.
The first troubleshooting step is determining whether the candidate previously generated a profile code using an old or alternative SIM card. In the JAMB architecture, a profile code generated with an NIN is permanent and never expires across academic sessions. If the candidate still has the old SIM card, they should insert it into a mobile phone and send the word RESEND to 55019 or 66019. The central server will transmit the original ten-digit profile code, allowing the candidate to purchase their registration e-PIN immediately without generating a new code.
If the candidate has never registered for UTME previously or has lost the original telephone line, the issue constitutes a profile conflict that cannot be resolved via SMS shortcodes or cyber cafes. The candidate must visit an official state zonal office of the Joint Admissions and Matriculation Board. The candidate presents their original National Identification Number (NIN) slip, birth certificate, and a valid government identification document. The administrative desk officer queries the forensic database to inspect the conflicting profile. The candidate completes a live biometric fingerprint scan. Once the system forensically verifies that the candidate is the rightful owner of the NIN, the unauthorized profile is detached, and the candidate’s authentic phone number is linked to the national profile code.
Official administrative guidelines enforced by the Joint Admissions and Matriculation Board warn candidates that attempting to circumvent this error by purchasing unauthorized SIM cards or using a third party’s NIN constitutes examination fraud and leads to permanent disqualification.
Data security standards monitored by the Standards Organisation of Nigeria ensure that biometric identification protocols maintain strict forensic integrity across all verification channels.
Resolving NIN profile conflicts early guarantees that candidates complete examination registration and portal transactions without unnecessary delays.
Candidates should safeguard their registered phone number and profile code in secure personal archives to prevent future administrative complications.
Safeguarding profile credentials guarantees uninterrupted access to national board services throughout undergraduate admissions exercises.
Prompt correction of data entry errors guarantees smooth progression through every stage of tertiary matriculation.
Thank you EduTalks! My sister was worried about this exact issue yesterday, sharing this with her immediately.
Great article. The distinction you highlighted between the institutional requirements and the general regulations is very important.
Thank you for this detailed guide! The step-by-step breakdown makes it very straightforward to navigate.
Extremely clear and helpful explanation. This cleared up the exact questions my study group was having regarding this process.
This was really helpful and timely. Thank you for consistently publishing reliable educational resources for students across Nigeria.
Quick question please: if an applicant has already completed the initial registration, can changes still be made within the correction window without penalty?
Great question. Yes, most examination and admission bodies allow data corrections during the designated modification window before final data lock. However, ensure that any biometric, course, or institution amendments are processed strictly through accredited CBT or administrative centers to prevent profile suspension or upload mismatch.
Very informative post. I wish our secondary school guidance counselor had explained this so thoroughly.
Very practical breakdown. It is reassuring to find verified information without all the rumors circulating on social media.
Bookmarking this right away. This is by far the most detailed article on this topic I have come across online.
Please, does this same policy apply to candidates who sat for WAEC GCE as private candidates rather than internal school candidates?
Thank you for asking. Yes, WAEC GCE (private candidate) certificates and results carry the exact same legal and academic validity as internal school candidate results for admission and institutional clearance purposes. When filling portal documentation, ensure your exam year, center number, and candidate number match your official result slip exactly.
