Welcome to Rainbow Federal Credit Union.

We have been serving our members since 1956 and if you have not already joined Rainbow, we would like you to consider the benefits of belonging to this credit union. The small town neighborhoods that used to exist when we were first chartered in the 50’s were special; we knew each other, we interacted with one another, and we watched out for each other.

We may offer the latest technology . . . but the basics of helping each other out as we did over 50 years ago has not changed. As a member of Rainbow FCU, you become a part of our family. Your financial needs will become as important to us as they are to you. When it’s time to buy a new car or home or start a nest egg, you will find our rates extremely attractive.

Currently we serve ALL of Androscoggin and Oxford Counties as well as New Gloucester, and you are able to sign up for membership at any of our branches in Lewiston, Auburn, Mechanic Falls or South Paris.

To become a member of Rainbow Federal Credit Union, you need to meet the following criteria:

  1. Work, reside or attend school within our field of membership which includes the communities listed above, or have an immediate family member who is a  Rainbow FCU member in good standing, and . .
  2. Provide two forms of identification:  A photo ID such as your driver’s license or a student ID; and the other needs to be your social security card. The only exception is a military ID in place of the social security card. After 9/11 the rules have changed, and the restrictions on financial institutions have become more rigid.
  3. Open and maintain a Savings Account with a minimum balance of $25.00
