BIN Checker
Look up the card brand, type, issuing bank, and country behind any 6-8 digit card prefix — free, right here. No card numbers stored.
Only the first 8 digits are ever sent or looked up — enough to identify the issuer, never enough to identify a specific card.
Demo limited to 5 lookups / minute per visitor. For production use, integrate the BIN Lookup API.
Catch card testing
Flag checkouts where the billing country doesn't match the card's issuing country — a strong carding signal.
Prepaid & virtual cards
Detect prepaid and virtual card BINs commonly used for disposable, fraudulent, or high-risk transactions.
Smarter routing
Route transactions by card brand or issuing bank, or apply extra checks to specific BIN ranges.
Combine with VPN checks
Pair BIN country with Fraudex's IP country and VPN detection for a much stronger fraud signal, in the same API key.
