What is a BIN?

What is a bank card BIN? Why check it and how?

All credit and debit cards issued by any financial institution are assigned a Bank Identification Number (BIN).

We provide information about:

- what charge card information is in the BIN and when you can't do without it;
- how to ascertain whether the BIN is correct, as it is very important when for some reason it is not possible to make a payment. This becomes particularly important when you have decided to make a long trip.

The initial six digits on the card are the BIN.

The main purpose of the code is to identify a financial institution in the payment systems (PS) when carrying out transactions with your card. The first digit is the marker of the PS where it is serviced. For American Express it is 3, for VISA it is 4 and Master Card is 5.

BIN also indicates the bank and country where this payment instrument was issued and to which premium level it belongs (Classic, Electron, Gold and others) and category (debit, credit, debit with an overdraft).
