What is Greip BIN Lookup?
It identifies card brand, issuer, card type, and issuer country from the Bank Identification Number prefix so businesses can enrich checkout and fraud workflows before capture.
BIN Lookup for Smarter Payment Decisions
A BIN (Bank Identification Number) is the leading digit range on a payment card. Greip BIN Lookup turns that prefix into issuer context your team can use before capture: card brand, debit or credit type when known, issuing bank, prepaid signals when available, and issuer country.
Built for payment, risk, and operations teams that need issuer data inside checkout and fraud workflows. Greip connects through a documented API your engineering team can adopt when you are ready.
Common Usage

- Billing vs card country review

- Chargeback investigation

Problem
Customers can submit cards that pass basic format checks while issuer, country, or product type still conflicts with your policy. Teams often learn about the mismatch only after a decline, a chargeback, or hours spent in manual reference tables.
Static spreadsheets do not keep pace as issuers re-range cards, so merchants lack one reliable source of issuer metadata at scale.
Solution
Greip BIN Lookup helps merchants see whether a prefix maps to a known scheme, which institution issued the range, and where the card was issued when that data is available. Use it to compare billing country, customer location, and shipping address, decide when to request extra authentication or manual review, and flag prepaid or commercial products if your rules require it.
Issuer data supports payment risk decisions alongside your processor and Greip payment fraud analysis. It does not verify card ownership, available funds, transaction legitimacy, PCI compliance, or that a charge should be approved. Treat output as enrichment for your own policies.
Try one prefix on the free BIN lookup tool for manual checks. When you need volume in your own systems, your developers can use the BIN lookup documentation to connect Greip.
