Welcome to Credit Union ONE!

How Do I Become a Credit Union ONE Member?

Joining Credit Union ONE couldn't be simpler. Every member must open a Regular Share Savings with a minimum $6.00 initial deposit, and must maintain a $5.00 minimum balance at all times. Our field of membership is open to everyone by virtue of our shared support for the cancer care and research programs at Barbara Ann Karmanos Cancer Institute, to which $1.00 of each initial deposit becomes a one-time donation. By opening this "Share" account you automatically become a member-owner, with full access to our entire range of Credit Union ONE products and services

Credit Union ONE is a full-service, community based and operated financial institution that provides a complete range of financial services with the convenience, ease, affordability and dependability that only a member-owned cooperative can offer. With more than 118,000 members, $800 million in assets, and 19 branch offices in the Detroit, Grand Rapids and Traverse City metropolitan areas we're one of Michigan's largest credit unions, and with 70 years of service, one of the oldest. Deposits at Credit Union ONE are federally insured by the National Credit Union Administration (NCUA), and membership is open to all.  Join Now!
