Generate dummy American Express card numbers

This American Express test card generator creates dummy Amex-style card details for development and QA. Generated numbers use 15 digits, Amex-style formatting, and a 4 digit CVV value.

The generated values are test data only. They are not real American Express cards, are not linked to cardholders, and cannot be used for real transactions.

Why Amex needs separate testing

American Express cards commonly use a different number length and CVV length than many other card networks. Testing Amex-style data helps catch form layouts, validation rules, and checkout assumptions that only work with 16 digit cards.
