FakecreditcardAbout BIN 527379
In our BIN data, 527379 is a Mastercard Prepaid debit card range that belongs to LLC Bank Round, registered in Russia. 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 14 BINs, LLC Bank Round ranks 43rd among the 73 banks we list for Russia. The LLC Bank Round BIN list shows all of them with network, type and level.
Across Russia, the dataset counts 6,542 BINs; among the 4,768 that name an issuer, the main networks are Visa (45%), Mastercard (36%), Maestro (11%), and 61% are debit. See the Russia BIN list or the Russia card generator.

Is 527379 a debit or a credit card BIN?
It is recorded as debit, product level Prepaid. 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).
How many digits does a card with BIN 527379 have?
Mastercard card numbers have 16 digits, and the security code is a 3-digit CVC2 on the back. The first six digits are the BIN, the last digit is the Luhn check digit, and the digits in between identify the account.
Can I generate test card numbers with BIN 527379?
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 LLC Bank Round, 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.
