credit card bin test
A credit card BIN test reads the first six to eight digits of a card number to reveal the issuing bank, brand, card type, and country of issue.

Onyx GiftCards are “Open Gift Cards” which means that they can be redeemed at multiple merchant locations. They are standard credit card size, can fit into the average wallet and made of PVC plastic. Onyx GiftCards are Barcoded for security and safety for the consumer and bear a disclaimer at the back.
Onyx Giftcards can be bought with a branded Card backer which is black in colour and is designed to fit the card. There is an area to write a brief message to the recipient as well.
A card BIN test checks the first six to eight digits of a payment card against bank identification number records. It returns the issuing bank, card brand, card type (credit or debit), and the country where the card was issued. The test runs before authorization, so it does not confirm that the account is open, funded, or authorized by the cardholder.
The BIN is the leading segment of a card number. ISO/IEC 7812 sets the structure: the first digit marks the major industry, the next five digits identify the issuer, and the remaining digits cover the individual account plus a check digit.
The first digit also points to the network. A 4 signals Visa, a 5 signals Mastercard, a 3 covers American Express and Diners Club, and a 6 covers Discover.
A BIN range belongs to a bank or a program manager, not to one cardholder. A single BIN can sit behind millions of cards, which is why BIN data describes a group rather than a person.
Subscription merchants watch BIN-level approval rates for recurring charges. A range that approves the first payment but fails on renewal points to issuer rules about stored credentials or grace periods.
Marketplaces use BIN rules to screen sellers and payouts. A mismatch between the seller's stated country and the card's issuing country is a common fraud signal.
Some people run BIN checks on stolen card numbers to sort live accounts from dead ones. That activity is carding, and it is illegal in the United States under wire fraud and access device statutes. Card networks and payment processors close accounts tied to it, and the Federal Trade Commission pursues the operators who sell the data.
A BIN lookup on its own returns public range data, so the value in that scheme comes from the stolen numbers, not from the test. Merchants who need to verify a card use authorization, address verification, and CVV checks instead.
A BIN test is one input in a longer chain. The authorization request travels to the issuer, which approves, declines, or refers the charge. Address verification and CVV checks add signals about the cardholder.
Tokenization replaces the card number with a token so the merchant stores no primary account number. Truncated data, meaning the first six and last four digits, carries far less risk and falls outside much of the scope of PCI DSS.
No. It identifies the issuer and applies routing or risk rules. Only the issuing bank approves a charge.
No. BIN data comes from the prefix of the number. CVV and AVS data come from the card itself and the billing address, and the issuer verifies them during authorization.
Yes. Issuers add, retire, and reassign ranges as portfolios move between banks or processors. A BIN database needs regular updates to stay accurate.
High fraud rates, prepaid funding, or a mismatch with the merchant's customer base. Merchants set those rules to cut disputes and losses.
Not by itself. A BIN points to an issuer, not a cardholder. The full card number is the sensitive part, which is why PCI DSS controls how it is stored and transmitted.
