BIN Lookup Tool
Use the BIN lookup to identify the bank, card brand, card type, and country behind the first digits of a payment card. It helps payment, fraud, and support teams understand transaction context before they decide what to retry, review, or route.
What is a BIN?
A bank identification number, also called an issuer identification number, is the opening sequence of a payment card number. It identifies the institution and card network connected to the card.

It can also explain why a payment needs a different authorization route, extra verification, or a softer retry strategy.
SmartRetry uses card and issuer context to help merchants recover legitimate payments that were declined for fixable reasons.
How to use the BIN lookup

Use it in context
BIN data is one signal among many. Use it to support routing, troubleshooting, and fraud review — not as a standalone risk decision.
