How to Update Your MTN Biometric Details in Ghana — Complete 2026 Guide

Biometric verification has become a cornerstone of SIM registration and identity management in Ghana’s telecommunications sector. For MTN subscribers, biometric details—such as fingerprints—are now tightly linked to SIM registration, Ghana Card verification, and access to Mobile Money (MoMo). When biometric records are outdated, missing, or mismatched, subscribers may experience service restrictions, failed SIM verification, or MoMo access issues.

This Accra Street Journal guide explains how to update your MTN biometric details in Ghana, who needs to do it, what documents are required, where to go, how long it takes, and why biometric updates are increasingly important in 2026 and beyond.

What Are MTN Biometric Details?

MTN biometric details refer to unique physical identifiers captured during SIM registration or verification, primarily:

• Fingerprints

• Facial image (where applicable)

• Ghana Card biometric confirmation

These details help MTN:

• Confirm the true identity of SIM owners

• Prevent SIM fraud and impersonation

• Protect Mobile Money wallets

• Comply with National Communications Authority (NCA) regulations

Biometric data complements the Ghana Card by adding an extra layer of identity verification.

Why You May Need to Update Your MTN Biometric Details

Updating biometric details is not something most users think about—until there is a problem. Common reasons include:

• SIM shows “Partially Registered”

• SIM verification keeps failing

• Mobile Money transactions are restricted

• SIM replacement or ownership change required

• Biometric capture was skipped or incomplete

• Data mismatch between MTN and Ghana Card systems

• Regulatory audits flag your SIM

In many cases, biometric updates are required to finalise SIM registration.

Who Needs to Update MTN Biometric Details?

You are likely required to update your biometric details if:

• Your SIM was registered online without biometric capture

• Your SIM was registered before full Ghana Card enforcement

• Your SIM status shows partial registration

• You recently replaced your SIM

• You changed SIM ownership

• MTN or the NCA flagged your SIM for review

Fully registered SIMs with confirmed biometrics usually do not need updates unless an issue arises.

Is Updating MTN Biometric Details Mandatory?

Yes—when required.

If MTN requests biometric updates and you do not comply:

• Your SIM may be restricted

• Calls and data may be suspended

• Mobile Money access may be limited

Biometric compliance is now part of ongoing SIM validation, not a one-time exercise.

Before visiting an MTN service centre, ensure you have the following:

Mandatory Requirements

• Original Ghana Card

• Your MTN SIM card

• Knowledge of your MTN phone number

Optional but Helpful

• SIM pack or PUK (if available)

Photocopies or digital images of IDs are not accepted.

Where to Update MTN Biometric Details in Ghana

Step-by-Step: How to Update Your MTN Biometric Details

Step 1: Visit an MTN Service Centre

Go in person with your Ghana Card and MTN SIM.

Step 2: Request Biometric Update

Inform the customer service agent that you want to:

• Update or complete your biometric details

Step 3: Identity Verification

MTN will:

• Verify your Ghana Card

• Match your SIM registration details

• Confirm ownership of the number

Step 4: Biometric Capture

You will be asked to:

• Scan fingerprints

• Possibly take a facial image

This step ensures your identity matches national records.

Step 5: System Update and Confirmation

Once captured:

• Biometric data is uploaded to MTN’s system

You may receive confirmation immediately.

How Long Does It Take to Update MTN Biometric Details?

• In-store processing: 10–20 minutes

• System synchronisation: Immediate to a few hours

• Full verification: Same day in most cases

During busy periods, processing may take longer.

How to Confirm Biometric Update Was Successful

After updating biometrics, verify your SIM status.

MTN SIM Status Code

Dial: *400#

Expected Result

• Fully Registered / Verified

If the status still shows Partially Registered, allow a few hours and check again. If unresolved, return to the service centre.

How Biometric Updates Affect Mobile Money (MoMo)

Biometric verification is closely linked to MoMo security.

Before Biometric Update

• MoMo transactions may fail

• PIN reset may be blocked

• Wallet recovery may be restricted

After Biometric Update

• Full MoMo functionality restored

• Wallet balance remains intact

• Improved account security

Biometric updates do not delete your MoMo wallet or transaction history.

Common Biometric Update Issues and Solutions

Problem 1: Ghana Card Details Don’t Match

Cause: Incorrect SIM registration details
Solution: Data correction before biometric capture

Problem 2: Fingerprint Not Recognised

Cause: Poor scan or system error
Solution: Repeat capture or use alternate fingers

Problem 3: SIM Registered Under Another Name

Cause: Third-party registration
Solution: Ownership must be corrected first

Problem 4: System Delay After Capture

Cause: Network synchronisation lag
Solution: Wait a few hours or revisit service centre

Difference Between Biometric Update and SIM Registration
