FakecreditcardAbout BIN 666400
BIN 666400 is listed as a Maestro Standard debit card in Luxembourg. 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). Standard marks an entry-level consumer product.
The dataset does not name the issuing bank for this range. That is common for ranges that are new, private or used by processors on behalf of several banks.
Luxembourg has 417 BINs in the dataset; among the 293 that name an issuer, the main networks are Visa (44%), Maestro (35%), Mastercard (20%), and 63% are debit. See the Luxembourg BIN list.

Frequently asked questions
Which bank issued BIN 666400?
The dataset does not name an issuer for BIN 666400, only the country (Luxembourg). The network is Maestro.
Is 666400 a debit or a credit card BIN?
It is recorded as debit, product level Standard. 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 666400 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 666400?
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 any bank, 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.
