Credit card numbers for testing your e-commerce applications

I have developed multiple E-Commerce sites (Mostly using a home grown Paypal /Verisign gateway). However I am always forgetting the format of some of these wrong so here is the test credit card numbers:

• American Express: 3111-1111-1111-1117
• Visa: 4111-1111-1111-1111 or 4222-2222-2222-2222
• MasterCard: 5111-1111-1111-1118 
• Discover: 6111-1111-1111-1116

Your CCV number and Name should not matter. Stay below $500 dollars as well make sure your date is not today but in the future.

Example:

Visa:4222-2222-2222-2222

CCV:123

Name:Homer J. Simpson

Expiration Date: 0110

Amount: $486.65

Hope this helps. Enjoy.
