BIN 666349 — Lookup & Card Details

Check bank, country, card type, and issuer information for BIN 666349.

What is BIN 666349?

BIN 666349 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.

Payment processors read these digits on every transaction: they drive routing decisions, currency handling at checkout, fraud scoring and card-product acceptance rules. BIN 666349 carries no personal information: it maps to an issuing institution and card program, never to an individual account or person.
