FAQ

Which bank issued BIN 340016?: According to the open BIN dataset, BIN 340016 is attributed to SANTANDER MEXICO in Mexico. Banks rename and BIN ranges move, so treat this as a best-effort reference.
Can I use BIN 340016 for real payments?: No. These numbers are for testing only. They have no balance and cannot be charged. Attempting real transactions with numbers you do not own is illegal.
Do the generated numbers pass Luhn validation?: Yes. Every number is generated with a valid check digit, so it passes the Luhn (MOD 10) check — exactly like a real card number would.
Will my gateway accept these numbers?: In test mode, gateways typically accept only their own documented test numbers. Generated numbers are best for validating formatting, Luhn checks, storage and UI behaviour.
