This free online business name lookup tool will search the Secretary of State’s database of registered business names. New Hampshire law requires that anyone doing business under any name other than his or her own must register that name with the Secretary of State.

The Secretary of State will not register a name that is deceptively similar to one already registered.  Business entity registration forms are available at our website at http://www.nh.gov/sos/corporate/index.html

Enter a business name to lookup:
(This can be a partial or full name.)

Search tip: Do not use suffixes (i.e.  ", Inc.") at the end of the business name search, just use the primary name of the company, this will produce a more successful result in your search.

Please note that this site is for informational purposes only and is not intended for use with determining the availability of a name for business registration purposes. Final determination of the availability of a name is made by the Secretary of State’s office at the time the completed paperwork is finalized.
