NH QuickStart Portal Access
The New Hampshire Secretary of State provides the QuickStart Business Inquiry portal as the primary tool for checking entity name availability. Access this free database through the official NH SOS website at sos.nh.gov by navigating to the "Business Search" section and selecting "Business Record Search."
The QuickStart portal contains records for all registered business entities in New Hampshire, including active, dissolved, suspended, and forfeited companies. This database covers LLCs, corporations, partnerships, and other entity types with their current status, formation details, and registered agent information.
Before conducting your search, understand that QuickStart results provide preliminary information only. The Secretary of State makes final determinations on name distinguishability during the official filing process, so a clear preliminary search does not guarantee approval.
Search Parameters and Strategies
Use multiple search approaches to identify potential name conflicts. The QuickStart portal offers several search options including "Starts With," "Exact Match," "Contains," and "All Words" to help capture variations that might cause distinguishability issues.
Start with an exact match search using your proposed entity name. Then broaden your search using partial terms and variations. For example, if checking "Granite State Consulting LLC," also search for "Granite State," "Granite Consulting," and similar combinations.
Consider these search strategies:
- Search without entity designators (LLC, Inc., Corp.) to find similar names across entity types
- Check phonetic variations and common misspellings
- Look for abbreviated versions of words in your proposed name
- Search individual words separately to identify potential conflicts
The portal allows searches by entity name, Business ID, Filing Number, or Registered Agent. Use the registered agent search if you suspect existing entities might share similar ownership or management structures.
Interpreting Search Results
Review search results carefully to assess potential conflicts. The portal displays entity name, type, status, formation date, and other key details. Pay attention to entities with similar names regardless of their current status, as dissolved or suspended entities may still create distinguishability issues.
Entity status information follows common entity status labels used across state databases. Active entities pose the most obvious conflicts, but inactive entities with similar names may still prevent approval of your proposed name.
Examine the complete entity details by clicking through to individual records. Look for business addresses, registered agents, and filing history that might indicate connections to your proposed entity or industry sector. Shared registered agents or addresses could signal related business operations.
No search results matching your proposed name suggests availability, but remember this represents preliminary information only. The Corporations Division conducts the official review during formation or reservation filings.
Name Distinguishability Rules
New Hampshire requires entity names to be distinguishable from existing registered businesses. Names cannot be identical or confusingly similar, even with variations in spelling, punctuation, or entity designators.
The Secretary of State evaluates distinguishability based on the overall impression created by the name, not just exact word matches. Similar-sounding names or those that differ only in minor ways may be rejected. For example, "Riverwalk Studios LLC" and "Riverwalk Studio LLC" could be considered too similar.
Entity type designators like "LLC," "Inc.," or "Corp." are required for their respective entity types but do not create distinguishability by themselves. A proposed "ABC Company LLC" would likely conflict with an existing "ABC Company Inc." if the core business names are otherwise identical.
Certain words require special approval or are restricted entirely. Banking terms, professional designations, and government-related words may need additional authorization. Check the official NH SOS guidelines for current restrictions before finalizing your name choice.
Name Reservation Process
Reserve an available name through Form 1: Application for Reservation of Name if you need time before filing formation documents. Submit this form online through the NH SOS portal, by mail to Corporation Division at 107 N Main St, Room 204, Concord, NH 03301, or in person.
Name reservations protect your chosen name for up to 120 days from the approval date. The current reservation fee structure should be verified on the official Secretary of State website, as amounts and processing methods may change.
The reservation application requires your proposed entity name, the type of entity you plan to form, and your contact information. Include alternative name choices if your primary selection faces conflicts during the review process.
Approved reservations provide exclusive rights to use the reserved name for the specified period. You cannot extend reservations, but you may file a new reservation application if additional time is needed before formation.
Common Verification Mistakes
Avoid assuming a clear QuickStart search guarantees name approval. The preliminary database search identifies obvious conflicts, but the Corporations Division makes final determinations based on distinguishability standards that may catch subtler similarities.
Do not limit searches to exact matches only. Many name conflicts arise from variations that seem distinguishable to applicants but create confusion under state standards. Always use multiple search approaches and consider how similar names might appear to the general public.
Remember that name availability differs from trademark clearance and domain availability. Conduct separate searches through the USPTO database and domain registrars to avoid intellectual property conflicts and secure your online presence.
Contact the NH SOS Corporations Division at 603-271-3246 during business hours (8am to 4:30pm ET, Monday through Friday) for guidance on specific distinguishability questions. While staff cannot guarantee approval, they can provide insight into potential issues before you file formation documents.
Verify current forms, fees, and procedures on the official sos.nh.gov website before submitting any applications. State requirements and processing details change periodically, and this guide provides general workflow information rather than definitive current specifications.
