New Hampshire Naming Requirements

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 restrictions for LLC names:

  • 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.


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 all other existing or reserved business names in the state.

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

  • 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.
