FakecreditcardAbout BIN 557583
In our BIN data, 557583 is a Mastercard Prepaid debit card range that belongs to Bank of Ceylon, registered in Sri Lanka. 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 31 BINs, Bank of Ceylon ranks 6th among the 12 banks we list for Sri Lanka. The Bank of Ceylon BIN list shows all of them with network, type and level.
Across Sri Lanka, the dataset counts 403 BINs; among the 383 that name an issuer, the main networks are Visa (62%), Mastercard (33%), American Express (3%), and 45% are debit. See the Sri Lanka BIN list.

Can I generate test card numbers with BIN 557583?
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 Bank of Ceylon, 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.
