Assumed Business Name Registration – While not a business license, it’s common for Sole Proprietorships and Partnerships operating under a name that is different from the full name of the owner(s) to register for an Assumed Business Name (also known as a Doing Business As or DBA) with the Municipal or Town Clerk’s Office in the county where the business is located.
