Some credit unions are closed, serving only their members. However, the more and more popularitywin cooperatives of open type. The number of shareholders of a credit union is limited and formalized by a list. Limit of the number is defined by the assembly and such assembly establishes the charter. Credit union services are available only to its shareholders. Credit unions base their activities on savings of shareholders, their shares and savings contributions, which make up the fund of mutual financial assistance - a source of cash loans to shareholders.

Unlike banks credit unions limit their activities to a closed circle of people.

Credit union as a consumer cooperative operates on the principles of equality of all its members.
