Every year, many candidates who register for the Joint Admissions and Matriculation Board (JAMB) examination make mistakes while filling in their personal or academic information. These errors can happen due to oversight, incomplete documents, or issues with National Identification Number (NIN) linkage. To help students, JAMB introduced the Correction of Data service, which allows candidates to make necessary updates.
In this detailed guide, we will cover everything you need to know about JAMB correction of data in 2025, including the exact details you can and cannot change, the requirements, fees, deadlines, risks, and step-by-step instructions. This will help you avoid errors that could affect your admission chances.
Understanding JAMB Correction of Data
What is JAMB Correction of Data?
JAMB correction of data is an official service that allows candidates to edit specific information they provided during JAMB registration. This feature was introduced because JAMB realized that small errors in data entry could lead to big problems during admission processing.
For example, a candidate who mistakenly selected the wrong gender, date of birth, or course of study could lose admission opportunities if those errors were not corrected.
Why JAMB Correction of Data is Important
-
Admission Validation – Universities and polytechnics require accurate data. Any mistake can lead to disqualification.
-
NIN Integration – Since JAMB now links details directly with NIN, inconsistencies between the two can create serious problems.
-
Course and Institution Flexibility – Correction allows candidates to change course or institution based on cut-off marks.
-
Avoiding Legal Issues – Wrong details like state of origin or date of birth could be flagged as falsification.
Categories of JAMB Data Correction
In 2025, JAMB officially allows candidates to correct certain categories of information. Below is a breakdown:
1. Change of Course/Institution
-
You can change your preferred institution (university, polytechnic, college of education, etc.).
-
You can also change your chosen course if your UTME score does not meet the original requirement.
2. Change of Name
-
This includes corrections to spelling errors in first name, middle name, or surname.
-
Candidates with NIN-linked discrepancies in names must correct them for proper admission processing.
3. Change of Date of Birth
-
JAMB allows corrections if your date of birth was wrongly entered.
-
This is critical because age affects eligibility for NYSC (National Youth Service Corps).
4. Change of Gender
-
Some candidates mistakenly select the wrong gender. JAMB correction service allows this update.
5. Change of State/LGA of Origin
-
Candidates can correct their state or Local Government Area of origin if they selected the wrong one during registration.
6. Change of Passport Photograph
-
If the uploaded passport is wrong, blurry, or belongs to another candidate, you can request correction.
What You Cannot Change in JAMB Data (2025)
While JAMB gives room for flexibility, there are strict rules about certain details that cannot be corrected. These include:
-
UTME Subjects Combination – Once chosen during registration, you cannot edit your subject choices.
-
UTME Exam Scores – Your exam results cannot be changed or upgraded by correction of data.
-
Registration Number – Your JAMB registration number is unique and permanent.
-
Email Address Used for Registration – You cannot change the original email used for JAMB profile creation.
-
NIN Details After Linking – Once NIN is linked to JAMB, core NIN information like parents’ details cannot be changed through JAMB; only NIMC (National Identity Management Commission) can handle it.
Fees for JAMB Correction of Data in 2025
In 2025, the cost of correction varies depending on the type of data:
-
Change of Course/Institution – ₦2,500 (per change)
-
Correction of Name, DOB, Gender, State/LGA, Passport – ₦2,500 (each correction)
