测试用的美国信用卡号 Test Credit Card Numbers

These credit card numbers can be used to test a transaction at ECHO. They are numbers that banks will reject as invalid without problem and are intended for system testing. 

These test numbers work just like live accounts, but none of the transactions are actually settled and no money moves. Be sure to use valid data or you will get errors on things like card numbers, checking information, check writer ID info, etc. Please do not use a real credit card with test accounts unless you run a $1.00 transaction. If you do more, your card will have the funds held by each authorization until it expires. The test card will always give a result, the address verification and security code will match regardless of the input values. Furthermore, it will authorize with no expiration date. If you need to see different address verification and security code results, you must use a live credit card. In this case, please use low dollar amounts ($1.00).
