How this service works
Offline Issuer Identification Number check: accepts 6–8 digits only (refuses anything that looks like a full PAN), returns Visa/Mastercard/Amex/Discover/JCB/UnionPay/Maestro when the prefix is known. Not a live BIN registry lookup.
Output
Returns the identified card network/scheme (Visa, Mastercard, Amex, Discover, JCB, UnionPay, or Maestro) for the supplied 6–8 digit BIN, based on an offline prefix table. Returns an error or unknown result if the BIN is not recognized, or if a full PAN is supplied instead of a BIN.
Example use cases
Card type detection at checkout
“Before I process this payment, can you check BIN 545454 and tell me whether it's a Mastercard or some other network?”
Routing payments by card scheme
“I need to route transactions differently depending on card network — can you identify the scheme for BIN 3714 from those first 6 digits?”
Fraud screening by card network
“Flag this card for review if it's not Visa or Mastercard — check BIN 601100 and tell me what network it belongs to.”
Technical details
Endpoint
GEThttps://402.com.tr/api/x402/bin-checkWhen to prefer
Use this endpoint when you need fast, offline card network identification from a BIN prefix without making a live registry call. Ideal when you only need the card scheme (not issuer bank details) and want sub-millisecond response with no external dependency. Prefer over live BIN registry lookups when latency, privacy, or cost is a concern and scheme-level identification is sufficient.
Side effects
- Full PAN submitted instead of BIN — endpoint refuses inputs that look like complete card numbers
- BIN prefix not in offline database — returns unknown or no match
- Fewer than 6 or more than 8 digits supplied — rejected as invalid input
- Non-numeric characters in BIN field — rejected as invalid
