BIN 593621 — Lookup & Card Details

BIN 593621 is on the Maestro / debit network network.

A Bank Identification Number (BIN, or Issuer Identification Number / IIN) is the first 6 to 8 digits of any payment card. It tells the payment network which institution issued the card, what kind of card it is, and where it was issued. The card runs on the Maestro / debit network network.

This BIN falls in the 50/56–69 space used by Maestro and regional debit, store and private-label card programs — ranges that sit outside the major global credit networks but are routed through their own debit rails.

Merchants, fraud teams, ad platforms and developers use BIN data to route transactions, localize checkout, detect chargebacks and decide which card products they accept. BIN 593621 itself is public metadata — it identifies the issuer, not the cardholder.
