How to Get Bank Account Information From Cancelled Checks
When you deposit a check at a bank, the bank will stamp the name of the bank and your account number on the back of the check. Banks will either send you a copy of the canceled checks written on your account or provide you with electronic copies of the cancelled checks upon request. By looking at the stamp on the back of the cancelled check, you can find the name of the bank where the check recipient deposited the check and the account number that received the funds.
Turn the canceled check over. If you have an electronic version of the canceled check, look at the check's rear image.
Locate the electronic stamp that contains the name of a bank on the back of the canceled check.
Locate the account number. You will find the account number listed immediately above or below the bank's name on the electronic stamp. This indicates the bank and account where the recipient of the check deposited the proceeds from the check.
