Common GTBank Error Codes
In today’s digital age, banking in Nigeria has become faster and more convenient with platforms like Guaranty Trust Bank’s (GTBank) mobile app (GTWorld), USSD (*737#), internet banking, and ATMs. However, many users still encounter error codes and messages during transactions — such as “X00024” — that interrupt payments or transfers.
For most Nigerians, seeing an error code during a transfer, bill payment, or ATM withdrawal can be confusing and stressful — especially when money is debited but the transaction fails. Despite their prevalence, these error codes are often misunderstood. They are not arbitrary; each code communicates a specific issue in GTBank system, whether it relates to network problems, insufficient funds, invalid account details, or system maintenance.
This article dives deep into the most common GTBank error codes in Nigeria, explaining what each code means, why it occurs, and, most importantly, how you can fix it quickly. Whether you are using the mobile app, USSD, ATM, or POS, this guide will help you navigate these errors with confidence, reduce transaction failures, and ensure smoother banking experiences. An error code appears when a transaction cannot be completed successfully.
Common causes include:
- Temporary system maintenance
- Network connectivity issues
- Exceeded transaction limits
- Insufficient funds
- Incorrect beneficiary details
- Interbank routing delays
Common GTBank Error Codes and What They Mean
- Temporary System or Network Issue: This is one of the most referenced GTBank error codes. The bank’s system cannot process your transaction due to temporary issues such as system downtime, high traffic, or network delays.

Solution:
- Wait a few minutes and retry

- Try a different channel (e.g., USSD if the app fails)
- Transaction Failed / General Failure: The transaction could not be completed.
Causes:
- Insufficient funds
- Invalid account details
- System timeout
Solution:
- Confirm your available balance
- Verify beneficiary account details
- Avoid rapid retries; check transaction history first
Authentication Failed / Invalid PIN: Your authentication failed during a USSD or mobile app transaction.
Causes:

Solution:
- Wait and retry later
- Use a different banking channel, e.g., USSD, app, or ATM
- Monitor GTBank announcements for updates
Invalid Account Details: The beneficiary account number or bank does not match GTBank records.
Causes:
- Typing errors in the account number
- Wrong bank selected
- Closed or inactive beneficiary account
Solution:
- Double-check the account number and bank name
- Confirm details with the recipient
- Retry the transaction carefully
Duplicate Transactions Detected: The system suspects you are repeating the same transaction.
Causes:
- Multiple retries in a short time

ATM / POS Specific Errors (Dispense Failures): Sometimes money is debited but not dispensed at ATMs or POS devices.
Causes:
- ATM malfunction
- Communication failure between GTBank and NIBSS
- POS device issues
Solution:
- Wait for automatic reversal (24–72 hours)
- Contact GTBank via *737# support, GTConnect, or visit a branch
- Provide transaction details including time, amount, and reference number
Why GTBank Errors Happen More During Certain Times
Transactions may fail more often during:
- Late evenings
- Salary days
- Weekends and public holidays
This is usually due to high system traffic or scheduled maintenance. USSD services are also influenced by telecom networks, so poor signal strength can cause errors even when GTBank system is functioning properly.

To minimize errors:
- Use a stable internet connection
- Confirm beneficiary details before transferring
- Avoid repeated retries after a failure
- Keep the GTWorld app updated
- Ensure your account KYC is complete
- Use alternative channels if one fails
