In the U.S., credit unions have a clear organizational structure. All credit unions belong to one or the other parent credit union (there are 35 of them in the U.S.). Corporate credit unions are united on a cooperative basis in the Central Credit Union (US Central Credit Union). When organizing the credit union it is important that people know each other and know the extent to which each of them is trustworthy. The right to use the services of the credit union have only its members. U.S. credit unions have another significant difference from the credit cooperatives of farmers: the first have major proportion of short-term loans, the second - long and mostly in real estate. Credit union as a consumer cooperative operates on the principles of equality of all its members.
