Frequently asked questions
Which bank issued BIN 501661?
BIN 501661 is registered to Banco Comercial Portugues, S.A. in Portugal. Bank details can change after mergers or portfolio sales, so confirm with the bank for anything important.
Is 501661 a debit or a credit card BIN?
It is recorded as debit. 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 501661 have?
Maestro card numbers have 12 to 19 digits, and the security code is a 3-digit code (not on every card). 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 501661?
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 Comercial Portugues, S.A., 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.
