FakecreditcardAbout BIN 420508
In our BIN data, 420508 is a Visa Prepaid Classic debit card range that belongs to Aeon Financial Service Co., Ltd., registered in Japan. 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 63 BINs, Aeon Financial Service Co., Ltd. ranks 9th among the 49 banks we list for Japan. The Aeon Financial Service Co., Ltd. BIN list shows all of them with network, type and level.
Across Japan, the dataset counts 13,915 BINs; among the 5,015 that name an issuer, the main networks are Visa (36%), Diners Club (28%), Mastercard (23%), and 7% are debit. See the Japan BIN list or the Japan card generator.

Is 420508 a debit or a credit card BIN?

How many digits does a card with BIN 420508 have?
Visa card numbers have 16 digits (13 and 19 also allowed), and the security code is a 3-digit CVV2 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 420508?
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 Aeon Financial Service Co., 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.
