Local card networks in United States

Besides the international networks, the United States has its own card scheme. Its numbers often use prefixes that a Visa/Mastercard-only form rejects or labels wrongly, so test them on purpose.

Frequently asked questions

Can I generate a United States credit card number for testing?

Yes: the default prefix is 510255, a Mastercard debit range of Fiserv Solutions, LLC. The generator adds random digits and a Luhn check digit, plus an expiry date and CVV. Nothing is attached to them, so any real charge is declined.

Which card networks are most common in United States?

By BIN count in our data: Visa 33%, Diners Club 19%, Mastercard 11%, EBT 11%. Local networks: Discover (14,629 BINs). Debit ranges make up 39% and credit ranges 61%.

Which BINs do Visa cards from the United States start with?

Examples from different banks: 405957 (Bank of America, National Association); 401135 (JPMorgan Chase Bank, N.A.); 401671 (Wells Fargo Bank, N.A.); 403902 (Card Services for Credit Unions). See the United States BIN list for every bank.

Which currency should I use to test payments from United States?

USD (US dollar). Gateway APIs usually expect amounts in the smallest unit (for example 1050 for 10.50). If you sell abroad, test USD and your settlement currency — cards from the United States work with both.

Can I use a generated United States card number to buy something?

No — format only. Banks in the United States decline numbers they never issued, which is every generated number. If you need to pay, a bank virtual card or a wallet such as Cash App Pay is the safe route. Testing a checkout? Use your gateway’s sandbox test cards.

What does a Discover card number look like?

Discover numbers start with 6011, 644–649 and 65 and have 16/17/18/19 digits with a Luhn check digit. Make sure your card form accepts these prefixes instead of rejecting them as an unknown brand.

Which payment methods should a checkout for United States offer next to cards?

ACH Direct Debit: Debits a verified US bank account after the customer accepts a mandate; confirmation can take up to 4 business days. Cash App Pay: Customer-initiated wallet payment from Cash App, supported by Stripe in USD.
