Minnesota nonprofit corporations are not required to use any of these words; for business corporations, they must use "corporation", "incorporated", or "limited", or shall contain an abbreviation of one or more of these words, or the word "company" or the abbreviation "Co." if that word or abbreviation is not immediately preceded by the word "and" or the character "&" Chapter 302A, Section 302A.115 Minnesota Statutes (for Business Corporations); Chapter 317A, Section 317A.115 Minnesota Statutes (for non-profit corporations)
Your name must be unique, and not deceptively similar, to any other trademarked name or business. It is also required that your name not be used to intentionally misrepresent the products or services you offer. For LLCs, nearly all states will also require you to add a signifier of your limited liability status, such as "LLC" or "L.L.C." to the end of your company's name. You may be able to operate under a name other than your formal LLC name by applying for and using a dba.
