Do I use the old credit card test numbers for testing in the Sandbox ?

When you create a new Sandbox test account, you can configure the account with a mock DISCOVER®, VISA®, American Express®, or MasterCard® credit card (you can also create a test account without a credit card). Navigate to the Funding tab on the test account’s Profile page to obtain the credit card number to use while testing. Configure separate test accounts to cover each of the credit cards you need to process.
