Due to road closures on Friday, September 5, 2025, the Polk City lobby will be closed and the drive up will only be accessible by walk up.

Attention Deposit Account Customers:

Effective September 2, 2025, you will no longer be able to use your GSB debit/ATM card to deposit at non-GSB owned ATMs. You will still be able to deposit at the GSB owned ATMs located at each of our four (4) branches. You can also conveniently deposit checks via Mobile Deposit through our mobile app. If you are not currently set up for Online or Mobile Banking, stop in or contact any of our branches and a personal banker will assist you.

To learn more about how to use Mobile Deposit, visit our Online Banking Education Center.

We understand that this may change how you deposit, however, this decision has been made due to the increasing level of risk associated with check fraud deposits occurring at ATMs.
