Why was my credit card declined on the CodeGuard payment page?

Updated on August 21, 2026

Overview

This article explains why a credit card is declined on the CodeGuard payment page and what you can do to complete your payment. It covers the common causes of a decline — incorrect card details, cards issued outside the United States, and card issuers that do not participate with the payment processor CodeGuard uses — along with the accepted card types, the checks to make before trying again, and when to contact CodeGuard support. Throughout the article, Card Verification Value (CVV) refers to the short security code printed on your card.

What is a declined card on the CodeGuard payment page?

A declined card means the CodeGuard payment page could not complete the charge, so the payment was not processed. The decline is returned by the payment processor or by the bank that issued the card, not by CodeGuard directly. No charge is applied to the card when a payment is declined.

Common causes of a declined card

Incorrect card details entered. This is the most common cause. The card number, Card Verification Value (CVV), or expiration date entered on the payment page does not match the details on the card.
Card issued outside the United States. The payment processor CodeGuard currently uses has had occasional problems processing overseas credit cards.
Card issuer does not participate. A decline can also occur when the bank that issued the card does not participate with the payment processor CodeGuard uses.
Card type is not accepted. CodeGuard accepts all major credit cards. A card outside these types may not be accepted.

Accepted card types

CodeGuard currently accepts all major credit cards:

Visa
American Express
MasterCard
Discover

Steps to resolve a declined card

Check the card number. Compare the number entered on the CodeGuard payment page against the number printed on the card.
Check the Card Verification Value (CVV). Re-enter the short security code printed on the card.
Check the expiration date. Confirm the month and year entered match the card.
Confirm the card type. Confirm the card is Visa, American Express, MasterCard, or Discover.
Submit the payment again. Enter the corrected details on the CodeGuard payment page and submit the payment.
Try a different card if the payment is still declined. If the card was issued outside the United States, or by an issuer that does not participate with the payment processor, use another major credit card.
Contact CodeGuard support. If the payment is still declined after these checks, contact CodeGuard support so the account can be created.

How to verify the payment was accepted

The payment is accepted when the CodeGuard payment page confirms the transaction and the CodeGuard account is created. If the payment page returns a decline message again, the payment was not processed and no charge was applied to the card.

Frequently asked questions

Why was my credit card declined on the CodeGuard payment page?

The most common reason is that the card number, Card Verification Value (CVV), or expiration date entered on the payment page is incorrect. A decline can also occur with cards issued outside the United States, or when the card issuer does not participate with the payment processor CodeGuard uses.

Which credit cards does CodeGuard accept?

CodeGuard accepts all major credit cards, including Visa, American Express, MasterCard, and Discover.

Will I be charged if my payment is declined?

No. A declined payment is not processed, so no charge is applied to the card.

Why is my overseas credit card declined?

The payment processor CodeGuard currently uses has had occasional problems processing credit cards issued outside the United States. If an overseas card is declined repeatedly, try another major credit card or contact CodeGuard support.
