Enter the first 6 to 8 digits of a card to see its network, card type, issuing bank and country. Free, no sign-up, and we never ask for a full card number.
A BIN is the first 6 to 8 digits of a debit, credit or prepaid card number. It tells the payment system which card network the card belongs to and which institution issued it, so the payment can be routed to the right bank for approval.
You will also see it called an IIN, or issuer identification number. That is the name used in the ISO/IEC 7812 standard, because not every card issuer is a bank. The two terms mean the same thing.
Every card in a range shares the same BIN, so a BIN describes the card product, not the person. The digits that follow identify the individual account, and the last digit is a check digit that catches typing mistakes.
A BIN check describes the card range. It never reveals anything about the cardholder or their account.
To check that a full number is typed correctly, use the card number validator, which runs the Luhn check in your browser.
The network can be recognised from the first one to four digits alone. These are the ranges the checker uses.
| Network | Starts with | Card length |
|---|---|---|
| Visa | 4 | 13, 16 or 19 digits |
| Mastercard | 51–55, 2221–2720 | 16 digits |
| American Express | 34, 37 | 15 digits |
| Discover | 6011, 644–649, 65 | 16–19 digits |
| JCB | 3528–3589 | 16–19 digits |
| UnionPay | 62 | 16–19 digits |
| Diners Club | 36, 300–305, 38–39 | 14–19 digits |
| Mir | 2200–2204 | 16–19 digits |
| First digit | Industry |
|---|---|
| 1–2 | Airlines (2 is also used by Mastercard and Mir) |
| 3 | Travel and entertainment: American Express, JCB, Diners Club |
| 4–5 | Banking and financial: Visa, Mastercard |
| 6 | Merchandising and banking: Discover, UnionPay |
| 7 | Petroleum and other future use |
| 8 | Healthcare, telecoms and other future use |
| 9 | Assigned by national standards bodies |
Some ranges are shared through partnerships, for example Discover accepts many UnionPay and Diners Club cards, so the issuing network and the network that processes a payment can differ.
For decades a BIN was six digits long. As the supply of 6-digit ranges ran low, the ISO/IEC 7812 standard was changed to allow 8-digit BINs, and Visa and Mastercard began issuing them from April 2022.
Card numbers did not get longer. The BIN simply takes two more digits from the account part of the number, and existing 6-digit BINs remain in use, so both lengths are live today.
That is why the checker accepts 6, 7 or 8 digits. Network details are read from the digits you enter, and bank and country records are matched on the first six.

Merchants and payment providers often set rules by BIN. If your card keeps being refused at one site but works elsewhere, one of these is a likely reason:
Checking the BIN tells you which of these could apply. If you need a card from a particular network or country, every Qwikvcc card page lists its network, issuing country and currency before you buy.
Browse virtual cardsNetwork, card length and industry come straight from the digits, so they are always right for the number you enter. Bank, country and card type come from the binlist.net database, a public BIN directory. Like any BIN list it can be out of date when banks merge or re-use ranges, and new ranges can be missing. For a definitive answer, the bank named on the card is the source.
Yes. BINs are public reference data that banks, merchants and payment providers use every day. A lookup only needs the first 6 to 8 digits, which do not identify anyone. Never share a full card number, expiry date or CVV with any lookup site, including this one.

Contact supportA BIN (bank identification number) is the first 6 to 8 digits of a payment card number. It identifies the card network and the institution that issued the card, and usually the card type and the country it was issued in.
Yes. IIN (issuer identification number) is the official name in the ISO/IEC 7812 standard. It replaced "BIN" because not every card issuer is a bank, but both terms mean the same leading digits.
No. A BIN is shared by every card in that range, often thousands or millions of cards. It says nothing about the person who holds the card, the account number or the balance.
No. A BIN lookup only describes the card range. To check that a number is typed correctly, use a Luhn check such as our card validator. Only the issuing bank can confirm whether a card is active and has funds, and that happens when a payment is authorised.
Free BIN databases do not cover every range. Newly issued BINs, 8-digit BINs and some prepaid or virtual card ranges are often missing. The network, card length and industry shown by the checker still come straight from the digits.
The checker only accepts 6 to 8 digits and only sends the first 6 to our server, never a full card number, expiry date or CVV. We keep the public bank result for that BIN so the next lookup is instant.
Yes. Banks merge, sell card portfolios and re-use ranges, and networks are moving from 6-digit to 8-digit BINs. If a result looks out of date, the bank named on the card or statement is the reliable source.
Each Qwikvcc card page lists the card's network, issuing country and, where available, its BIN, so you can check it here before you buy.
