The majority of credit cards are issued by banks or similar financial institutions. You can identify the bank using BIN, or “bank identification number”, which is also the first four to six digits of the credit card. Knowing your credit card’s financial backer will help you make a decision about which card is best for you. Debit cards and check cards are also included in the BIN database.
Find the first six digits of the credit card number in question, on the card or on the credit card statement. You can even do this for someone else’s credit card without having to see the entire number.
Look in the bank identification number database (see Resources section) for the first four digits. On a Windows or Linux computer, press “Control + F” and on a Mac “Apple + F” to find the pop-up toolbox and enter the numbers to find it automatically. If there are multiple lists for the first four digits, add in the next two to search for the full six digits. The list is complete, including many international banks, so without this number, you may have the number of an unlisted international bank. In that case, call the number on the back of the credit card.
Call the number on the back of the credit card if six digits are not on the BIN list. The BIN list is complete, including many international banks, so you can have the number of an unlisted international bank.
Visit the website of the bank or financial institution listed for more information about that bank’s policies and credit cards.
