VCC Glossary: BIN, CVV, 3DS, KYC & Card Terms
The acronyms on every virtual and credit card — BIN, CVV, CVC, 3-D Secure, KYC, MCC — each controls something specific at checkout. Here is what they mean and why they matter.
If a charge fails, it is usually one of these: a BIN the merchant does not accept, an AVS/CVV mismatch, or a 3DS step you skipped. Knowing the terms shortens the debugging.
The numbers on the card
The BIN (Bank Identification Number, the first 6–8 digits) tells the network who issued the card and where — this is why some merchants block whole BIN ranges. CVV/CVC is the card verification value; EMV is the chip standard behind in-person taps.
Tokenization and PCI
PCI is the data-security standard governing card storage; tokenization is the technique that lets merchants avoid storing your real number.
The checks at authorization
KYC (Know Your Customer) is the issuer's identity check before they let you hold the card. MCC (Merchant Category Code) labels what kind of business is billing you and drives rewards and blocks. OTP is the one-time passcode behind 3-D Secure step-up.
JCB and other networks
JCB is a Japanese card network alongside Visa, Mastercard and Amex; virtual cards mostly ride the big two.
Deep dives on specific questions
credit card jcb
JCB is a global card network founded in Japan, competition to Visa, Mastercard and Amex, and accepted across Asia plus a growing set of international merchants through partnerships. A JCB credit card is simply a card issued on that network, so where it works depends on JCB's acceptance deals, not the issuing bank. In the VCCFinder data JCB ranges are a smaller slice than Visa or Mastercard, and their clearing behaviour at Western checkouts, AWS, Netflix, OpenAI, differs enough that you should check before assuming parity. If your spend is Japan or Asia heavy, a JCB range can clear where others stall, while if it is US SaaS, a Visa or Mastercard range we have logged is usually the safer bet. Acceptance, not the logo, is what gets your charge through.
virtual card no kyc
A 'no KYC' virtual card is marketed as one you can open without identity verification, but in practice 'no strict KYC' is the honest phrase, because lighter checks, not none. Issuers still collect basic signals, email, device, sometimes a phone, and regulators in most jurisdictions require some identity trail, so fully anonymous cards are rare and often short-lived. The trade-off is real, because lighter verification usually means lower limits, thinner support, and a higher chance of a sudden freeze. VCCFinder tracks roughly 38 ranges that open without strict KYC among the 456 we monitor, and we publish their clearing rates so you can weigh convenience against reliability. Use a no-strict-KYC range for low-stakes, capped spend, not as your only card for something you cannot afford to lose.
cvv vs cvc
CVV vs CVC is just branding: CVV is Visa's term, CVC Mastercard's, both the 3-digit card verification value. Functionally identical — the check that proves you hold the card at checkout.
what is bin
The BIN (Bank Identification Number) is the leading 6-8 digits that identify the issuer and country, which is why whole ranges get blocked or allowed at once. Reading it tells you more about a decline than the card art ever will.
Frequently asked
what does bin stand for on a card
BIN is the Bank Identification Number — the first 6-8 digits that tell the network who issued the card and where. Merchants and fraud systems use it to allowlist or block whole ranges, which is why some checkouts reject an entire issuer.
what is kyc in virtual cards
KYC (Know Your Customer) is the identity check an issuer runs before letting you hold the card — ID, address, sometimes a selfie. Lighter KYC means faster signup but usually lower limits and more freeze risk.
cvv vs cvc difference
They are the same idea — the card verification value printed on the card — just branded differently by network (CVV for Visa, CVC for Mastercard, CID for Amex). All are the 3-4 digit check that proves you hold the card.
what is an mcc code
MCC (Merchant Category Code) labels what kind of business is billing you — travel, SaaS, gambling and so on. Issuers and card programs use it to allow or block spend and to decide which rewards a purchase earns.
