Troubleshooting AVS Mismatches
If you receive an error message when attempting to add or save your credit card to your account profile, it is usually due to a strict security mismatch during the address verification system (AVS) check. To resolve this, please double-check that the following items exactly match the official records on file with your financial institution:
Billing address
Postal/zip code
Cardholder name
Next Steps with Your Bank
Note: If you have confirmed that all spelling and address fields are entirely accurate but you continue to experience an error, please contact your bank or credit card issuer directly. Inform them that you are attempting a secure card verification check and ensure they are not automatically blocking the authentication process. Once they authorize the check, try adding the card again.
