IIBK and CMYF Routing Numbers to Retire

All former Idaho Independent and Community First routing numbers will retire August 14, 2020. Please discontinue using these numbers (on checks and ACH transfers) and order new checks through online banking: Login, select “More…” from the menu, then “Reorder Checks” from the drop-down. Thank you for your cooperation!

We're available with 24/7 online and mobile banking, drive-ups, and ATMs. Our branch lobbies are temporarily closed.

On September 9, 2020, all First Interstate Bank locations will close at noon so our employees can volunteer in our communities for our third annual Commitment to Community Volunteer Day. 

In 2019, more than 2,100 First Interstate bank employees helped 220 nonprofit organizations across our six-state region. More than 8,000 volunteer hours were logged in just one day.  We are excited to think of new ways to help this year—either virtually or in small groups.

The deadline to submit is July 24, 2020.
