We put our
members first

Our members and their needs are our first priority.


Membership Eligibility

Eligibility for M-O Federal Credit Union membership includes not only federal and postal employees, but your family members as well. To us, 'family' includes any relative, either natural or through marriage. So whether they were born into your family or they joined your family through marriage (so, yes, your in-laws count too) they are eligible to join. That's a pretty broad definition and opens up membership eligibility at M-O FCU to your whole extended family!

This is where you come in if your already a member! Your whole family might not know about us or that they are eligible to join....invite your family to join M-O Federal Credit Union!

M-O Federal Credit Union's primary membership basis is government and postal employees who work in or are supervised from Beadle County, South Dakota. Our membership also extends to the following:

  • Entities under contract with the United States Government who work in or are supervised from Beadle County, SD
  • All county agricultural agencies who work in or are supervised from Beadle County, SD
  • Persons retired as pensioners or annuitants from the above employement
  • Members of their immediate family
  • Organizations of such persons

Upon joining M-O FCU, you become a member-owner. Your membership makes you eligible to utilize our full range of financial services. You may also take part in the election of officers and can hold an office yourself. Once you join, you are always a member, even if you no longer work for the Federal government or postal system and/or you move away.

The Credit Union Difference

A credit union is a not-for-profit financial organization owned and operated by its members for the benefit of all who belong. Credit unions are governed by a volunteer Board of Directors, elected by the members. The credit union concept is a simple one - members pool their savings and then make low-interest loans to each other. As not-for-profit financial service cooperatives, credit unions return earnings to their members in higher savings rates, better services, and lower borrowing rates.

M-O FCU's main purpose is to provide financial services to our members in a pleasant and friendly atmosphere. We pride ourselves in the personalized service you receive at your member-owned financial institution.
