Find your pertinent bank or card information

Credit Card
Your credit/debit card number and expiration date can be found embossed on the front of your credit/debit card. You will also need your credit/debit card security number which varies by location and number of digits. (This number is recorded as an additional security precaution.)

Visa:
Card Identification # 3-digit, non-embossed number printed on the signature panel on the back of the card immediately following the Visa card account number.

MasterCard:
Card Identification # 3-digit, non-embossed number printed on the signature panel on the back of the card.

Discover:
Card Identification # 3-digit, non-embossed number printed on the signature panel on the back of the card.

Checking/Savings Account:
Refer to this sample check for typical locations of the routing/transit and account numbers.

A common error is to enter the check number because on some checks it is found between the routing/transit number and the account number. If you are unsure what to enter, please refer to your monthly bank statement or contact your bank for assistance.

Here is a picture of a sample check when the check number is found in a different place.
