The Michigan Business Registration Certificate, also known as the Michigan Form 165, is a document issued by the Michigan Department of Licensing and Regulatory Affairs. It is required for any business operating in the state of Michigan. It includes information such as the name and address of the business, the type of business, and the owner's name and address. There are three types of certificates: a single-member LLC registration, a multi-member LLC registration, and a corporation registration. The registration is valid for five years from the date of issue and must be renewed before it expires. The certificate serves as proof of the business's legal status in the state of Michigan and is required for most business activities.
