FakecreditcardAbout BIN 506421
In our BIN data, 506421 is a Carnet Prepaid debit card range that belongs to Conexion Yucateca, registered in Mexico. Debit cards draw money directly from the cardholder's bank account, so checkouts and gateways often treat them differently from credit cards (fees, holds, recurring billing). Prepaid products are loaded with funds in advance instead of drawing on a credit line; subscription and recurring-billing flows often handle them separately.

Can I generate test card numbers with BIN 506421?
Yes. Open the generator with this BIN to create Luhn-valid numbers with expiry dates and CVVs for testing forms, validation and BIN-based rules. They are test data: not issued by Conexion Yucateca, linked to no account and declined by real payment systems.
Does a BIN tell me whether a card is valid?
No. A BIN describes a range of card numbers — network, issuer, country and product — not a particular card. Whether a card exists or can be charged is known only to the issuing bank. To check the format of a full number (length and check digit), use the card validator.
A BIN identifies the card network and the issuing institution only. It reveals nothing about an individual card, cardholder or account, and it cannot show whether a card exists or can be charged. Test numbers generated from a BIN are for development and QA only and are declined by every real payment system.
