Business Name Registration

Sole proprietors and general partners who want a business name that does not include the owner(s) full names (for example, Janice Smith’s Cleaning Service or Martha Harris and Tom Graham’s Maid Service) need to find out whether the name they want to use is available in New Hampshire.

Start with a statewide corporate business/trade name search by registering at the New Hampshire Department of State’s business portal NH QuickStart.

Do Your Own Search Online For Business Names

Then do an online search for names similar to the one you plan to use. For example, if you want to use the name, Crystal Clean Maid Service, do simple online searches for “Crystal Clean Maid Service+New Hampshire” plus Crystal Clean Maid Service+your county” and “Crystal Clean Maid Service+your town or city”.

Search beyond the first page of results. Go at least five pages deep into the search results to see if the name you want or similar names are being used in your state, county or city.

Name Registration Details

How An EIN Helps

Sole proprietors and general partners may apply for an Employer Identification Number (EIN) from the IRS even if they do not plan to hire employees.

Getting an EIN may make it easier to open a bank account and reduce your risk of identity theft.

You can apply for an EIN online.

In addition, some business registration forms will require a NAICS business classification number for the house cleaning industry.
