Membership Criteria

In order to join SFFCU, you simply need to live, work, worship or attend school in Minnehaha, Lincoln, McCook or Turner Counties. And if you’re a family member of an existing SFFCU member, you’re in, too! And membership lasts a lifetime—once you join, your membership sticks, whether you move, retire or change jobs.

Getting Started

There’s no scary signing requirements—when you’re ready to join, all you need is $5. To become a member, you simply need to open a deposit account with a minimum balance of $5, and you’ve officially joined the credit union. (And with membership comes access to all of SFFCU’s competitive, valuable services.)
