BIN / IIN Checker

What a BIN/IIN Actually Encodes

The first 6 to 8 digits of any payment card make up its Bank Identification Number (BIN), also called the Issuer Identification Number (IIN). This prefix isn't random — it's assigned by the card network to a specific issuing bank and card program, so every card from, say, a particular bank's premium travel card range will typically share the same BIN. Looking up a BIN tells you the network (Visa, Mastercard, RuPay, and so on), and often the specific issuing bank and card type, without revealing anything about the individual cardholder or account.

How Merchants and Fraud Systems Use BIN Data

E-commerce platforms and payment gateways routinely perform a BIN lookup in the background during checkout — it lets them apply issuer-specific rules (like enabling EMI conversion only for banks that support it), route the transaction efficiently, and flag mismatches that might indicate fraud (for instance, a billing address in one country against a BIN registered to a bank in another). None of this requires knowing anything about the specific card beyond its first few digits.

What This Checker Can and Can't Tell You

Enter the first 6–8 digits of a card, and this tool checks them against a curated database of publicly documented Indian issuer BIN ranges. If there's a match, you'll see the network, issuing bank, and card type on record. If there's no match, the tool falls back to identifying just the network from the leading digit pattern — a card can be perfectly genuine even if its specific bank isn't yet in our (necessarily incomplete) curated dataset.

Reading Your Own Card's BIN

You can safely enter just the first 6–8 digits of your own card here — that's a small, non-sensitive fragment shared with every merchant your card touches anyway, and on its own reveals nothing that could be used to make a purchase (unlike the full card number, expiry date, and CVV together). It's a useful way to double-check which specific card product you actually hold when a bank's naming across debit/credit variants gets confusing.

The Limits of Any Public BIN Database

No freely available BIN database is fully exhaustive or perfectly current — banks periodically launch new BIN ranges, retire old ones, or license ranges to co-branded partners, and none of that is centrally published in real time. Treat a "not found" result as inconclusive rather than as evidence the card is invalid, and treat a match as a best-effort identification rather than an authoritative one. For a definitive answer about a specific card, your bank's own customer service remains the only fully reliable source.
