In our BIN data, 557571 is a Mastercard Standard debit card range that belongs to Banco Nacional de Comercio de Timor Leste, registered in Timor-Leste.

Frequently asked questions

How many digits does a card with BIN 557571 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 557571?
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 Banco Nacional de Comercio de Timor Leste, 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.
