The field of membership includes those who live, work or worship in the Wyoming county of Natrona. Membership only requires a $5 deposit into a share account.
The credit union is NCUA insured. It's a small credit union with only 1089 members with one branch located in Casper, Wyoming.
Since Wyoming is a small state with a population of only 500K, I don't come across too many credit unions from Wyoming. This is only the second Wyoming credit union that I've posted on. The last was Warren FCU of Cheyenne.
