FakecreditcardAbout BIN 550843
BIN 550843 is listed as a Mastercard Prepaid debit card issued by Mutual Trust Bank, Ltd. in Bangladesh. 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.
Mutual Trust Bank, Ltd. has 40 BINs in the dataset, which makes it the third-largest of 23 banks with a BIN page in Bangladesh. The Mutual Trust Bank, Ltd. BIN list shows all of them with network, type and level.
Bangladesh has 706 BINs in the dataset; among the 675 that name an issuer, the main networks are Visa (64%), Mastercard (20%), Local brand (6%), and 48% are debit. See the Bangladesh BIN list or the Bangladesh card generator.

How many digits does a card with BIN 550843 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 550843?
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 Mutual Trust Bank, Ltd., 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.
