FakecreditcardAbout BIN 436731
In our BIN data, 436731 is a Visa Prepaid debit card range that belongs to University National Bank, registered in the United States. 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.
With 11 BINs, University National Bank ranks 686th among the 775 banks we list for the United States. The University National Bank BIN list shows all of them with network, type and level.
Across the United States, the dataset counts 156,869 BINs; among the 73,133 that name an issuer, the main networks are Visa (50%), Mastercard (22%), Discover (17%), and 46% are debit. See the United States BIN list or the United States card generator.

How many digits does a card with BIN 436731 have?

Can I generate test card numbers with BIN 436731?
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 University National Bank, 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.
