Anybody can join a credit union, however each credit union serves what’s called their “field of membership” – The field of membership of a credit union is the legal definition of who is eligible to join the credit union (simply put it’s the commonality between the members). You may be eligible to join a credit union based on your:

Employer – many employers sponsor their own credit unions (worker cooperative)
Geographic Location – many credit unions serve anyone that lives, works, worships, or attends school in a particular geographic area 
Family – most credit unions allow members’ families to join. So if someone in your family is already a member of a credit union – you may be eligible too!
Membership in a group – like a church, school or alumni, labor union, homeowners’ association, etc.
