New Hampshire Business Name Search: How to Check and Reserve a Name

Starting a business in New Hampshire begins with one critical step: finding and protecting the right name. Whether you're forming an LLC, corporation, or operating under a trade name, you need to confirm your chosen name is available and meets state requirements. This guide walks you through how to search for business names in New Hampshire and reserve one before filing your formal incorporation or formation documents.

What You'll Need Before You Start

Before you begin your New Hampshire business name search, gather these resources:

  • Internet access and a web browser to access the NH Secretary of State's online database
  • Your proposed business name (have 2 to 3 backup options ready)
  • A credit card if you want to reserve your name immediately (reservation fee is $15)
  • Knowledge of your business structure (LLC, corporation, or trade name registration)
  • State-specific naming rules for your chosen business type (detailed below)

You do not need an attorney or business consultant to perform a basic name search, though you may want to consult a lawyer if you're concerned about trademark conflicts or have a complex business structure.

Understanding New Hampshire Name Requirements

Before searching, know what New Hampshire requires of business names.

For LLCs

If you're forming a limited liability company, your company name must include the words "limited liability company" or the abbreviation "L.L.C." (or similar variations such as "LLC" or "llc"). Examples: "Mountain Home LLC," "Granite State Services Limited Liability Company," or "NH Digital L.L.C."

Your name must also be distinguishable from every other business name already formed, registered, or reserved with the New Hampshire Secretary of State. This includes trade names and any business administratively dissolved within the last 120 days. Keep in mind that articles (a, an, the), plurals, phonetic spellings, abbreviations, and added prefixes or suffixes do not make a name distinguishable. For example, "Granite LLC" and "The Granite LLC" are considered the same name and both cannot be used.

For Corporations

Corporations must not include "LLC" or "limited liability company" in their name, as these terms are restricted to LLCs. A corporation name should end with "Inc.," "Corporation," "Incorporated," "Corp.," or similar indicators. Like LLCs, corporation names must be distinguishable under the same rules.

For Trade Names (DBA)

If you're operating under an assumed or trade name different from your legal name, you must register it with the Secretary of State. Trade names have similar distinctness requirements but do not require the "LLC" or corporate designation.

Step-by-Step: How to Search a Business Name in New Hampshire

Step 1: Access the Business Search Database

Open your web browser and navigate to the New Hampshire Secretary of State's official business search tool at https://quickstart.sos.nh.gov/online/BusinessInquire. This free database is maintained by the Corporation Division and is the authoritative source for checking name availability.

You do not need to log in or create an account to perform a basic search. The tool is public and accessible 24/7.

Step 2: Enter Your Proposed Business Name

In the search field, type your proposed business name exactly as you intend to file it. For example, if you want to form "Granite Solutions LLC," type that complete name with the LLC designation.

The search accepts partial matches, so you can also search just the primary name (e.g., "Granite Solutions") to see all similar variations already on file. This helps you identify whether names that are similar, but not identical, are in use.

Step 3: Review the Search Results

The database will display any matches. Review the results carefully:

  • No matches found: Your name is likely available. However, this only means no identical or confusingly similar name exists in New Hampshire's business registry. It does not guarantee that no trademark exists nationally or that no one else is using the name informally.
  • Matches found: If you see your exact name or very similar names, you will need to choose a different name. The search results show the entity name, type (LLC, corporation, etc.), and status (active, dissolved, etc.).

Pay special attention to names of businesses still active or dissolved within the last 120 days. Names dissolved before the 120-day window are available again.

Step 4: Perform a Secondary Trademark Check (Recommended)

The New Hampshire business name search only checks the state's registry. It does not check federal trademarks or domain names. For extra protection, search the U.S. Patent and Trademark Office database at www.uspto.gov to ensure no registered trademark uses your proposed name. Also consider checking if your desired domain name is available.

This step is not legally required in New Hampshire but can prevent trademark disputes down the road.

Step 5: Reserve Your Name (Optional but Recommended)

If you've confirmed your name is available and you're not ready to file formation documents yet, you can reserve it for 120 days. This gives you time to finalize your business plan, secure funding, or handle other startup tasks without worrying that someone else will grab your name.

To reserve your name:

  1. Visit the NH QuickStart filing portal at https://quickstart.sos.nh.gov/online/Account/LandingPage
  2. Create a free account or log in if you already have one
  3. Select "Name Reservation" from the filing options
  4. Enter your proposed business name and specify the business type (LLC, corporation, etc.)
  5. Pay the $15 reservation fee by credit card
  6. Receive your reservation confirmation via email immediately

Once reserved, no one else can file that exact name for 120 days. The reservation is non-refundable and covers only the specific name you reserved. If you decide not to proceed, the name returns to availability after 120 days.

What Happens After You Find an Available Name

Once you've confirmed your name is available and reserved it (if you chose to), the next step is filing your formation documents:

  • For an LLC: File a Certificate of Formation (Form LLC-1) with the Secretary of State. Filing fee is $100.
  • For a corporation: File Articles of Incorporation (Form 11) with a $100 filing fee.
  • For a trade name: File a Trade Name Registration (Form TN-1) with a $50 filing fee (plus $2 electronic handling charge for online filings).

You can file these documents through the same NH QuickStart portal. Processing times vary; the Corporation Division posts its current processing date on the QuickStart login page. Expedited processing ($25 additional fee) is available in person at the Corporation Division Customer Lobby in Concord.

Common Mistakes to Avoid

1. Forgetting the LLC or Corporate Designation

If you're forming an LLC, you must include "LLC" or "limited liability company" in your name. Searching for just "Granite Solutions" without the LLC designation will not reserve the full legal name. Always include the complete designation when searching and reserving.

2. Assuming Name Availability Means Trademark Clearance

A name available in New Hampshire's business registry does not mean it's clear nationally. Another company could hold a federal trademark for that name, and you could face a cease-and-desist letter after you've already filed with the state and invested in branding. Always do a secondary trademark check before finalizing your choice.

3. Waiting Too Long After Reservation

Your 120-day reservation period expires regardless of whether you're ready to file. If you're close to the deadline and not prepared to file yet, renew your reservation early. Otherwise, your name becomes available for others to claim.

4. Overlooking the 120-Day Dissolution Window

If a business was dissolved, its name re-enters the available pool after 120 days. If you see a name in the database marked as "dissolved," confirm the dissolution date. If it's more than 120 days old, that name is technically available again, though it may still carry brand reputation or trademark considerations.

5. Neglecting to Maintain a Registered Agent

Once you file your formation documents, you must appoint a registered agent in New Hampshire. This is a separate requirement from the name search, but it's critical. Forgetting to maintain an agent can result in administrative suspension of your business.

Tips for a Smooth Name Search and Reservation

  • Search multiple variations of your name before deciding. Try adding or removing words, synonyms, or abbreviations to see what's already taken and to spark new ideas.
  • Have backup names ready. Your first choice may not be available. Having 3 to 5 alternatives prepared speeds up the decision-making process.
  • Check domain name availability at the same time. A name available in New Hampshire might have an unavailable domain, which could complicate your online presence. Use a domain registrar's search tool to confirm the .com (or desired extension) is available.
  • Document your reservation confirmation. Save the email confirmation of your name reservation. This serves as proof if anyone tries to claim the name during your 120-day period.
  • File promptly after reservation. Do not let your 120-day period lapse without filing your formation documents. Once it expires, your reserved name is available to anyone.
  • Consider your future growth. Choose a name that won't limit you if your business expands. Overly specific names (e.g., "Portland Granite LLC") can feel confining if you eventually serve a wider region.
