The Maryland Secretary of State does not have information regarding business licenses.  To find out if a business is licensed in Maryland, check with the Department of Commerce.

Search by Department ID

In addition to searching by the business name, you can search by Department ID if you already have that number.  The Department ID is a unique number provided by the Secretary of State to each entity.

Registered Agent

In Maryland, one of the requirements for a corporation or LLC is that a Resident Agent (commonly known as a Registered Agent) has to be named.  This person is a single point of contact in case the business needs to be served with legal papers or contacted by the state. One of the business owners often file as the entities Registered Agent. When they file, their home address is often used (PO Boxes aren’t allowed) and the owner's name and address is now a public record that can be looked up by anyone. This can be a big concern, especially for home-based businesses. Using a commercial Registered Agent service will keep their personal address from being public record..

Business Licenses

The business name registration is different from business licensing in Maryland.  The state of Maryland Business Express website has more information regarding Maryland business licenses.
