The registration requirement depends on the name being used. The official instructions require an assumed business name when the business name does not include the owner’s real and true name. Corporations and LLCs need the additional registration when they operate under a name different from their registered entity name.

  • For corporations, limited liability companies and other business entities, the business name registered with the Corporation Division is the real and true name of the business - no additional name registration is required. An assumed business name is only required for entities like corporations and LLCs if they are conducting business under a name other than the registered name for the entity.

Oregon’s county selection belongs within the Corporation Division registration: the name must be associated with at least one Oregon county and can cover all Oregon counties without an additional charge. It is not a direction to file the registration at a county clerk.
