Every year, thousands of candidates face delays, disqualification, or registration failure during JAMB because of biometric errors.
As JAMB continues to strengthen its anti-malpractice systems, biometric verification has become one of the most critical parts of JAMB 2026 registration.
Unfortunately, many candidates do not understand how biometric capture works or what mistakes to avoid. A simple fingerprint issue can prevent you from registering, printing your slip, or even sitting for the UTME.
In this guide, we explain the most common biometric errors during JAMB 2026 registration, why they happen, and practical steps you can take to avoid them.
What Is Biometric Capture in JAMB Registration?

Biometric capture is the process where JAMB records a candidate’s fingerprints and facial data during registration. This data is used to:
-
Prevent impersonation
-
Verify candidates on exam day
-
Ensure “one candidate, one registration”
-
Track CBT exam attendance
Without successful biometric capture, your JAMB registration is incomplete.

Why Biometric Errors Are a Serious Issue in JAMB 2026
JAMB has made it clear that no biometric = no exam. In 2026:
-
Candidates with unresolved biometric issues will not be allowed to sit for UTME
-
Biometric mismatches may lead to disqualification
-
CBT centers risk sanctions for repeated biometric failures
This makes it extremely important to understand the common biometric errors and how to avoid them.
1. Poor Fingerprint Capture (Most Common Error)
This is the number one biometric problem during JAMB registration.
Causes
-
Dirty or oily fingers
-
Excessively dry skin
-
Worn-out fingerprints (common among artisans)
-
Use of body cream or chemicals before registration
Effects
-
Fingerprint not detected
-
Incomplete registration
-
Biometric failure on exam day
How to Avoid It
-
Wash hands with clean water before registration
-
Avoid applying cream or oil on your fingers
-
Wipe fingers dry before capture
-
If fingers are dry, gently rub palms together
2. Fingerprint Mismatch Error
This occurs when the fingerprints captured during registration do not match those verified later.
Causes
-
Using different fingers during capture
-
Poor-quality initial capture
-
CBT center error
-
Attempted impersonation
Effects
-
“Biometric mismatch” warning
-
Denial of access to the examination hall
-
Possible investigation by JAMB
How to Avoid It
-
Ensure all ten fingers are captured clearly
-
Stay consistent during every biometric process
-
Avoid registering through unverified agents

3. Facial Capture Errors
Facial recognition is now a core part of JAMB’s biometric system.
Causes
-
Poor lighting at CBT center
-
Wearing face caps, glasses, or masks
-
Blurred camera lenses
-
Moving during capture
Effects
-
Incomplete facial record
-
Failure during exam-day verification
How to Avoid It
-
Sit upright and face the camera directly
-
Remove glasses, caps, and face coverings
-
Stay still during capture
-
Ensure proper lighting
4. Multiple Registration Attempt Error
JAMB’s system automatically flags candidates who attempt to register more than once.
Causes
-
Registering at different CBT centers
-
Restarting registration due to earlier errors
-
Using multiple profiles or phone numbers
Effects
-
Biometric conflict
-
Registration invalidation
-
Possible disqualification
How to Avoid It
-
Register only once
-
Resolve issues at the same CBT center
-
Never attempt a “fresh registration” without JAMB approval
5. Thumb-Only Capture Error
Some CBT centers mistakenly capture only thumbs instead of all ten fingers.
Why This Is a Problem
JAMB requires full fingerprint capture for accurate verification.
Effects
-
Incomplete biometric data
-
Failure during exam-day verification
How to Avoid It
-
Confirm that all ten fingers are captured
-
Ask the operator before leaving the center
-
Re-capture immediately if unsure
6. CBT Center Equipment Malfunction

Not all biometric errors are the candidate’s fault.
Causes
-
Faulty fingerprint scanners
-
Old or uncalibrated devices
-
Power interruptions
Effects
-
Poor biometric quality
-
Data not saved properly
-
Registration delays
How to Avoid It
-
Use only JAMB-accredited CBT centers
-
Avoid roadside or unapproved agents
-
Ask questions before capture begins
7. Network or Server Errors During Capture
Biometric data must sync with JAMB servers in real time.
Causes
-
Poor internet connection
-
Server downtime
-
Interrupted uploads
Effects
-
Incomplete biometric records
-
Registration not finalized
How to Avoid It
-
Ensure the CBT center confirms successful submission
-
Do not leave until registration status is confirmed
8. Candidate Physical Conditions
Some physical conditions can affect fingerprint capture.
Examples
-
Injured fingers
-
Burns or cuts
-
Skin peeling or infections
What to Do
-
Inform the CBT center immediately
-
Follow JAMB’s special biometric procedure
-
Do not attempt to hide the issue
JAMB provides alternative verification methods for genuine cases.
9. Underage or Identity Data Conflict
Biometric issues can arise when biodata conflicts with NIN records.
Causes
-
Wrong date of birth
-
Name mismatch between NIN and registration
-
Using another person’s NIN
Effects
-
Biometric rejection
-
Profile suspension
How to Avoid It
-
Ensure your NIN details are correct
-
Resolve NIN issues before JAMB registration
-
Never use another person’s NIN
