Our field of membership is a community membership covering Polk County, TN or Fannin, Gilmer, Union County, GA. You are eligible to join the Credit Union if you live, work or worship in any of these counties or are an immediate relative of any existing CBFCU member. Still a small, hometown financial institution, Copper Basin Federal Credit Union offers an attractive alternative to other local financial institutions. We strive to meet the financial needs of all our members, by offering a number of services to you – our members and owners.
