You may use the following credit card numbers to run tests on your Authorize.Net account.

The last testing card number is used to generate errors. This card is intended to return errors and should only be used if that is your intent. For example, you should use that number if you’re testing your site to see how it will respond to Authorize.Net errors.
Expiration date: Use any expiration date after today. If a CVV is required use any three digit combination (four digits if you’re using American Express).
Important: These are not real credit card accounts and will not generate an approval if your account is in live mode. They will return a decline in live mode and an approval in test mode.
