TundeYes, you can correct bio-data errors after JAMB registration but only through the official JAMB correction process.
Many candidates panic after completing registration and later discovering mistakes in their details. The good news is that corrections are possible but they must be done properly and within the approved correction window.
Common Bio-Data Errors Candidates Make:
- Wrong spelling of name
- Incorrect date of birth
- Wrong gender
- Wrong state or LGA of origin
- NIN (National Identification Number) mismatch
These errors may seem small, but they can cause serious problems during admission processing, NYSC registration, or even result verification.
The Joint Admissions and Matriculation Board (JAMB) is the only authorized body that can process official corrections. No cyber café, tutorial centre, or third-party agent has the authority to alter your details outside JAMB approved system.
Some corrections have strict deadlines. Delaying the process could limit your options or attract additional fees.

What Is Considered a Bio-Data Error in JAMB?
A bio-data error in JAMB refers to any mistake in your personal information submitted during UTME or Direct Entry registration. These errors can affect your admission processing if not corrected early.
Below are the common types of bio-data errors candidates encounter:
Name Correction (Spelling or Rearrangement)
This includes:
- Misspelled surname, first name, or middle name
- Wrong arrangement of names
- Omission of a name
- Difference between JAMB name and NIN record
Your name must match exactly with your NIMC (NIN) record.
Date of Birth Correction
If you mistakenly entered:
- The wrong day
- The wrong month
- The wrong year
You must correct it immediately. A wrong date of birth can affect admission, NYSC, and official documentation later.
Gender Correction
If you selected:
- Male instead of Female
- Female instead of Male
This can be corrected through the official correction process.
State / LGA of Origin Correction
Mistakes in:
- State of origin
- Local Government Area (LGA)
This is important because admission benefits, catchment areas, and state quotas may depend on correct origin details.
NIN-Related Mismatch
This happens when:
- Your JAMB details do not match your NIN information
- Your name or date of birth differs from what is on the NIMC database
In many cases, you must correct your details at NIMC first before updating JAMB.
Passport Photograph Issues
Problems may include:
- Wrong photo uploaded
- Blurry or unclear image
- Photo not matching candidate’s identity
Your passport must clearly show your face and match your biometric data.
Profile Code Errors
Issues related to:
- Wrong profile code generation
- Using someone else phone number
- Multiple profile codes
Profile code errors can affect access to your JAMB portal and correction process.
All corrections must be processed through the official system of the Joint Admissions and Matriculation Board (JAMB) at an accredited CBT centre.
Can All Bio-Data Errors Be Corrected?
Not all bio-data errors are treated the same way. While many mistakes can be corrected after registration, some require additional steps, and a few may be restricted.
Errors That CAN Be Corrected
Through the official correction process by the Joint Admissions and Matriculation Board (JAMB) at an accredited CBT centre, candidates can usually correct:
- Spelling errors in names
- Rearrangement of names
- Wrong date of birth
- Wrong gender
- Incorrect state or LGA of origin
- Course or institution (separate correction category)
These corrections usually require biometric verification and payment of the approved correction fee.
Errors That Require NIMC Correction First
If the mistake involves a mismatch between your JAMB details and your NIN record, you must:
- Visit a NIMC enrolment centre to correct the data first.
- Wait for the update to reflect in the NIMC database.
- Then proceed to a JAMB-accredited CBT centre for correction.
This commonly applies to:
- Name differences
- Date of birth mismatch
- Gender mismatch linked to NIN
JAMB cannot override incorrect NIN data directly.
Errors That May Not Be Changeable
Some details may be restricted or allowed only once, such as:
- Excessive name changes beyond minor spelling correction
- Changing identity-related details multiple times
- Certain biometric-linked data
In rare cases, if registration was completed using incorrect foundational data, correction may be limited.
Why Some Corrections Are Restricted
JAMB places limits on corrections to:
- Prevent identity fraud
- Reduce impersonation risks
- Maintain data integrity
- Align records with NIMC and other national databases
Because JAMB registration is linked to national identification systems, some changes are tightly controlled for security reasons.
The earlier you correct your bio-data error, the safer your admission process will be. Delaying correction can create complications later during admission screening or NYSC mobilization.
How to Correct Bio-Data Errors After JAMB Registration (Step-by-Step)
If you notice any mistake in your details after completing JAMB registration, follow these official steps carefully:
Step 1: Visit an Accredited JAMB CBT Centre
Only JAMB-accredited CBT centres are authorized to process bio-data corrections.
Do NOT attempt correction:
- At a random cyber café
- Through a tutorial centre
- Through an unofficial agent
Your biometric verification must be done physically at an accredited centre.
Step 2: Request “Correction of Data”
Inform the CBT official that you want to perform Correction of Data.
You will be required to:
- Provide your registration number
- Undergo biometric verification
- Pay the official correction fee
Biometric fingerprint verification is mandatory to prevent impersonation.
Step 3: Confirm Correct Details
Before submission, carefully cross-check:
- Full name (exactly as it appears on NIN)
- Date of birth
- Gender
- State and LGA
- Any other corrected field
Once submitted, further changes may require another payment.
Step 4: Print Your Correction Slip
After successful correction:
- Request and collect your Correction Slip
- Keep it safe as proof of correction
- It may be required during admission screening
JAMB Correction of Data Fee (2026)
Here is what candidates should expect regarding fees:
Official Correction Fee
JAMB usually charges a standard correction fee per change (commonly around ₦2,500 per correction subject to official confirmation for 2026).
Payment Method
Payment is typically processed:
- Through the official JAMB portal, or
- Directly at the accredited CBT centre
- Always ensure payment is properly receipted.
Corrections should be done early. Delaying may affect admission processing, school screening, or NYSC documentation later.
Deadline for JAMB Bio-Data Corrections 2026
The JAMB Correction of Data portal usually opens shortly after UTME registration begins and remains available for a limited period before or during the admission process.
When Does the Correction Portal Open?
- It typically opens after registration closes.
- Corrections are often allowed before admission lists are finalized.
- Specific deadlines are announced by the Joint Admissions and Matriculation Board (JAMB).
- Candidates should always check official JAMB announcements for exact timelines.
Why You Should Not Delay
Delaying correction can cause:
- Admission processing issues
- Mismatch between JAMB and school records
- Screening complications
- NYSC documentation problems later
- The earlier you correct your data, the safer your admission journey.
Risk of Waiting Until After Admission List Release
If you wait until:
- After your school releases admission lists
- After accepting admission on CAPS
- During Post-UTME screening
You may face serious complications, including:
- Name mismatch on admission letter
- Rejection during physical screening
- Delay in NYSC mobilization
Common Mistakes Candidates Make During Correction
Many candidates create bigger problems during correction by making these mistakes:
- Using Cybercafés Instead of Accredited Centres: Only accredited CBT centres can process official corrections. Using unauthorized centres can lead to invalid updates.
- Attempting Multiple Corrections Carelessly: Each correction attracts a fee. Making repeated unnecessary changes wastes money and may raise red flags.
- Ignoring NIN Mismatch: If your JAMB details do not match your NIN record, correction must start at NIMC. Ignoring this can cause long-term data inconsistencies.
- Not Printing the Correction Slip: Always collect and keep your correction slip. It serves as proof during admission screening.
- Waiting Until After Admission Processing: Correction should be done before schools begin screening and admission processing to avoid complications.
Verify all your details carefully before submitting any correction request. Prevention is cheaper and safer than multiple corrections.
