Mich. Comp. Laws § 456.118

Sec. 18. Prior to the filing by any corporation, in accordance with section 17, of the instruments thereby required with the corporation and securities commission, the corporation shall ascertain from the commission whether its corporate name is in conflict with that of any other corporation whose articles of association or articles of incorporation have previously been filed with the commission. If, in the judgment of the commission, there shall be a conflict in corporate names, then the corporation filing under the provisions of the section shall amend its name by adding thereto the name of the locality in which it is organized or operating, or in such other manner as shall be approved by the corporation and securities commission to distinguish it from any corporation whose articles have previously been filed as aforesaid.
