To place a stop payment on a stolen check, please visit a branch or contact our Member Service Center at 1-800-538-3328 for immediate assistance. If you have Online Access Home Banking or the mobile banking app, login and select Stop Payment from the Additional Services menu, More menu in the mobile app. It may also be necessary to change the share draft number on your account as a precautionary measure against unauthorized activity. The share draft number is the 14-digit number located on the bottom of your checks. Changing the number will only affect your checking account information not the account itself, and will not require you to close the account.
