Frequently asked questions
How do I check if a business name is available?
Search your state's business entity database (usually run by the Secretary of State; Delaware's is the Division of Corporations). Also search the USPTO trademark database and check the domain name and social handles.
How often must licenses be renewed?
Most local business licenses renew yearly; professional licenses often every 1–3 years with continuing education. Put the dates in your calendar.
Do I need a DBA?
If you trade under any name other than your legal name (or your LLC's registered name), most states or counties require a DBA / fictitious business name filing.
