Notify anyone making direct deposits to your previous account of your new Grinnell State Bank account information. For your convenience we have packets that include Direct Deposit Authorization Forms available at each of our locations.

Step 5: Close your previous checking account.

After all your checks and automatic payments have cleared, close your previous checking account.

Important Information about Procedures for Opening a New Account: To help the government fight the funding of terrorism and money laundering activities, Federal Law requires all financial institutions to obtain, verify, and record information that identifies each person or business that opens an account. What this means for you: When you open an account, we will ask for your name, address, date of birth, and other information that allows us to identify you. We may also ask to see your driver’s license or other identifying documents.
