How to Search Available LLC Names in New Hampshire

1. Check New Hampshire LLC Naming Guidelines

Before you do a name availability search, it makes sense to check if your business name meets the basic state guidelines.

Some key guidelines for New Hampshire LLC names include:

  • Your name must include the phrase “limited liability company” or one of its abbreviations (LLC or L.L.C.).

  • Your name may contain the name of a member or manager of the LLC.

  • Your name must be distinguishable from any existing business in the state. This includes New Hampshire reserved names.

Keep an eye out for restricted words. These words, such as “FBI” or “Treasury,” are often restricted to keep your LLC from sounding like an official institution.

New Hampshire also has the following LLC name restrictions:

  • Your name cannot imply that the LLC was organized for any non-permitted purpose or one not outlined in its certificate of formation.

  • Your name cannot include the name of a political party without authorization.

  • Your name cannot include the words "farmers' market" unless the LLC meets the definition of a farmers' market.

For more information, check out New Hampshire’s official state statutes.

2. Complete an LLC Business Name Search

Once you know your LLC name meets New Hampshire guidelines, it’s time to make sure it’s available by searching the New Hampshire QuickStart Business Search tool

It is important that your name be distinguishable from all other business names. In New Hampshire, a distinguishable name is one that is substantively different from any other registered or reserved business name in the state.

The following differences do NOT make a New Hampshire business name distinguishable:

  • Articles
  • Plural forms
  • Phonetic spellings
  • Abbreviations
  • Prefixes and suffixes (excluding antonyms)
  • Business entity type designators
  • Numeric designation
  • Punctuation and special characters
  • Spacing
  • Numerals vs. spelled out numbers

Failure to use a distinguishable name could result in your formation filing being rejected.

How to Reserve or Register Your Business Name

Reserve Your Name

You can optionally reserve your LLC name in New Hampshire for up to 120 days before you officially register it. This prevents other businesses from registering your name until you have the opportunity to register it yourself. 

Name reservations can be filed online or via hard copy with the New Hampshire Department of State. The filing fee is $15.

Register Your Name

If you want to register a legal entity name for your LLC, you can do so at the time of formation filing. New Hampshire provides a section for your desired LLC name on the Certificate of Formation.

Registering a DBA (doing business as) name, called a trade name in New Hampshire, is a separate process that requires filing with the Department of State.
