Government Travel Charge Card Declined Authorization Codes

Last updated May 2026

This Data Dictionary defines all Declined Authorization Codes that the Department of Defense (DoD) Government Travel Charge Card (GTCC) program generated in FY 2025. We will update this document annually to add any new codes. All codes and definitions were created in coordination with Citibank.

Code # Name Definition Resolution
2 Closed Account The cardholder or the issuing bank has officially closed the GTCC account. The Agency Program Coordinator (APC) should verify the account status in CitiManager. If the account is not marked ‘Closed Temporary Block', the cardholder must submit a new application.
7 Card Expired The card is invalid because its expiration date has passed. The cardholder can request a replacement card through CitiManager.
8 Charge-off Account The bank has closed the account and written it off as bad debt because of long-term non-payment. No transactions are permitted. The APC can verify the charge-off status in CitiManager. The cardholder must contact Citi to arrange payment for the outstanding balance, if applicable. The individual cannot reopen the account or apply for a new account under the SmartPay 3 contract.
14 Credit Revoked The issuing bank has permanently revoked all credit privileges for this account. The cardholder can no longer use this account. The cardholder may apply for a new account or use the organization’s Centrally Billed Account (CBA) if authorized and approved.
48 Not Enough Available Money The transaction amount is more than the available credit limit on the GTCC account. The APC may temporarily increase the credit limit in CitiManager to make sure enough credit is available for the cardholder’s mission. The cardholder can check their available credit limit 24/7 using CitiManager.
49 Excess Decline Authorizations Today The card declined too many times within 24 hours. This triggered a velocity limit that prevents any further attempts today. Cardholders should wait 24 hours for the counter to reset, or call Citi Customer Service for more help.
103 Invalid Card or Account The cardholder entered an incorrect or invalid card number or account information. The cardholder input the account number or information incorrectly. If concerned about potential fraud, the APC should ask the cardholder about it.
111 Bad PIN The cardholder entered an incorrect Personal Identification Number (PIN). This usually applies to ATM withdrawals or debit-like transactions. Cardholders can only view their PIN within the CitiManager App. To reset the PIN, contact Citi Customer Service at 1-800-200-7056.
112 Exceeds ATM Daily Limit The transaction would cause the total dollar amount withdrawn from an ATM in a 24-hour period to go over the set limit. Cardholders may enter a lower withdrawal amount. Otherwise, they should wait 24 hours and try the withdrawal again. Cardholders can contact their APC to verify withdrawal limits.
113 Exceeds Number ATM Per Day The cardholder has already made the maximum number of ATM withdrawals allowed in a 24-hour period. Cardholders can wait 24 hours and try to withdraw funds again. Cardholders can contact their APC for more help.
114 Exceeds Bad PIN Limit The cardholder has entered the wrong PIN too many times, and the bank has now blocked the card to prevent unauthorized access. Cardholders may view and reset their PIN through their CitiManager App. For more help, contact Citi Customer Service at 1-800-200-7056.
124 Invalid CVV2 or CVC2 The card verification value entered during the transaction does not match the code on the back of the card. This is a security measure to prevent fraud. Verify the CVV number and re-enter it. If the transaction declines again, the cardholder may consult the CitiManager App or contact Citi Customer Service at 1-800-200-7056.
125 Invalid Card Verification VAL/CHK The card verification value provided does not match the value on file for the card. Verify the CVV number and re-enter it. If the transaction declines again, the cardholder may consult the CitiManager App or contact Citi Customer Service at 1-800-200-7056.
134 Card Activation The cardholder must activate the card before using it. This is a security measure to make sure the card is in the hands of the legitimate cardholder. Cardholders should go to cardactivation.citi.com and follow the directions to activate their card. Cardholders outside of the US may contact Citi Customer Service at 1-800-200-7056 to activate their card.
146 Invalid CVC3/DCVV Value A contactless/mobile payment security failure occurred because the dynamic security code generated for the transaction was invalid. The cardholder should try the transaction again using the physical card (chip and PIN). If the issue continues, contact Citi Customer Service at 1-800-200-7056.
147 Wrong Entry Mode for Card The cardholder used the card in a way that is not permitted (e.g., swiping the magnetic stripe on a chip-enabled terminal that requires inserting the card). Cardholders should insert chip-enabled cards into the terminal's chip slot.
149 ATC Value Outside Window This is an EMV chip security feature. The Application Transaction Counter (ATC) from the chip is out of sync with the bank's records, which suggests possible card cloning. This decline is a security measure to protect against potential fraud. The cardholder should immediately contact Citi Customer Service at 1-800-200-7056, as the bank will need to block and replace the card.
151 Duplicate ATC This is an EMV chip security feature. Someone submitted the transaction with an Application Transaction Counter (ATC) that has already been used. This decline is a security measure to protect against potential fraud. The cardholder should immediately contact Citi Customer Service at 1-800-200-7056, as the bank will need to block and replace the card.
152 Exceeds Maximum RFID Amount The transaction amount is over the limit allowed for a single contactless ("tap-to-pay") transaction. The cardholder should complete the transaction by inserting the card and using their PIN.
162 Point of Sale Error The merchant's point-of-sale terminal, not the issuing bank, caused the decline. Merchants will need to resolve the issue with their acquiring bank.
207 Invalid Expiration Date The expiration date entered during the transaction is not the same as the expiration date on the card. Double-check the card expiration date and try the transaction again.
453 Cannot Authorize During Downtime The bank's authorization system was temporarily offline, so it could not process the transaction request. The cardholder cannot complete the purchase at that time and will need to try again later.
500 Coded Security Fraud - Lost The legitimate cardholder has officially reported the card as lost. The cardholder has reported the card lost or stolen.

The cardholder or APC should contact Citi Customer Service at 1-800-200-7056 to verify the attempted charge and to ask for more guidance.
519 Coded Security Fraud - Mail Or Phone The bank has flagged the transaction as potentially fraudulent because it was started by mail or phone, which are higher-risk channels.
