Before filing a New Jersey LLC, check the proposed name with the state’s Business Name Availability search. New Jersey requires an LLC name to use an accepted LLC designator and to be distinguishable in the filing office’s records.
The state portal also has a separate “Registered Businesses” search. That tool is useful for researching existing entities, but it does not answer the same question as the availability search used before formation.
Which New Jersey Business Name Search Should You Use?
The official portal includes two tools that look similar but answer different questions.
| Search | What It Does | Best Use |
|---|---|---|
| Search Registered Businesses | Searches the existing New Jersey business database and returns matching entities regardless of whether the name is available for a new registration. | Research an existing company, find similar names, or look up an Entity ID. |
| Search for Available Names | Determines whether a proposed name can be used to begin a new Business Formation application. | Check the name you want for a new New Jersey LLC. |
How to Check New Jersey LLC Name Availability
Open the official Business Entity Name Search
Go to the New Jersey DORES search portal. You do not need to use a third-party formation website just to check a name.
Select “Business Name Availability”
This is different from simply browsing registered businesses. The availability tool is designed to determine whether a name can be used to begin a Business Formation filing.
Enter the proposed business name
The availability search requires at least four qualifying characters. The portal excludes certain articles, spaces, punctuation, conjunctions and a trailing “s” when applying that minimum.
Review the availability result
If the name is not available, try changing a meaningful part of the name rather than relying on punctuation, capitalization or a tiny grammatical variation. The LLC punctuation guide explains why commas and periods do not count.
Check the name beyond New Jersey's entity database
Before investing in a brand, also check federal trademarks and practical issues such as domains and existing businesses using similar branding.
What Does “Distinguishable” Mean for a New Jersey LLC Name?
New Jersey law requires an LLC name to be distinguishable in the filing office's records from other entities and reserved names.
The official availability-search help page gives us something more useful than generic advice: it explains what the automated search ignores when looking for similar names.
The portal also adds a wildcard to the end of the proposed name so that similar names can be surfaced. This is why the availability tool is more useful than manually looking for one exact spelling.
New Jersey LLC Naming Rules
The New Jersey Revised Uniform Limited Liability Company Act sets the core LLC naming rules.
Rather than relying on a static list of supposedly “47 restricted words,” this page follows the statute's broader and more accurate rule: some words can be restricted under other New Jersey laws depending on the industry or activity.
How to Reserve a New Jersey LLC Name
If your LLC name is available but you are not ready to form the company, New Jersey law allows you to reserve the name.
For an LLC specifically, N.J.S.A. 42:2C-10 states that an available name reservation lasts 120 days. New Jersey's current DORES fee schedule lists the LLC name-reservation fee at $50.
Name reservation is optional. If you are ready to form the LLC now, you can usually proceed to the Certificate of Formation instead of paying for a separate reservation.
Alternate Names, DBAs and New Jersey LLCs
New Jersey terminology is easy to mix up:
| Term | Who Uses It? | Key Rule |
|---|---|---|
| Legal LLC name | Domestic New Jersey LLC | Must satisfy the LLC name and distinguishability rules. |
| Alternate name | Established NJ entities, including LLCs | Registered after the entity exists; current fee $50. |
| DBA for NJ registration | Out-of-state business whose exact legal name is unavailable in NJ | New Jersey's DORES guidance reserves this foreign-registration “dba” route for out-of-state businesses. |
Alternate Name for an Existing New Jersey LLC
Once an LLC has been established, it may register an alternate name to conduct business under another name. New Jersey's DORES states that the selection of an alternate name is not subject to the same name-availability requirements as the entity's legal name.
The current filing fee is $50, and registration is effective for five years. Registration does not give the LLC exclusive rights to the alternate name.
DORES currently uses Form C-150G for alternate-name registration. See the official New Jersey alternate-name guidance for filing and renewal instructions.
DBA for an Out-of-State Company
If an LLC was formed outside New Jersey and its exact legal name is unavailable in New Jersey, the foreign-registration process may require a secondary “doing business as” name. That is a different situation from an existing domestic New Jersey LLC registering an alternate name.
See the New Jersey foreign LLC guide if your company already exists in another state.
A New Jersey Name Search Is Not a Trademark Search
State LLC-name availability and trademark rights answer different questions.
The New Jersey search tells you whether a proposed entity name can be used in the state's business-formation system. It does not tell you that the name is safe to use as a brand everywhere in the United States.
Before investing heavily in branding, search the USPTO's current Trademark Search system for potentially conflicting federal marks.
A basic database search is useful screening, but trademark clearance can involve similarity of sound, appearance, meaning, and related goods or services. A database result by itself is not a legal opinion that a mark is safe to use.
What to Do After Your New Jersey LLC Name Is Available
If your proposed name passes the availability search and you are ready to proceed, move into the formation sequence rather than continuing to create extra naming filings you do not need.
The complete sequence is covered in the New Jersey LLC formation guide, while the New Jersey LLC cost guide separates mandatory and optional expenses.
Use the official Business Name Availability search, not just the registered-business browser. New Jersey's search ignores capitalization, spaces, several punctuation marks, leading articles, AND/OR/OF and a trailing “s” when looking for similar names.
If you need to hold an available LLC name before formation, the LLC statute provides a 120-day reservation and the current state fee is $50. After formation, an LLC can register a separate alternate name for $50; that registration lasts five years.

Frequently Asked Questions
Where do I search for an available New Jersey LLC name?
Use the official New Jersey Business Entity Name Search at njportal.com/dor/businessnamesearch and choose Business Name Availability.
Is searching registered businesses the same as checking name availability?
No. The registered-business search returns matching existing entities regardless of whether a name is available for a new registration. The Business Name Availability search is specifically designed to determine whether a proposed name can be used to begin a formation.
What does New Jersey ignore when comparing similar business names?
The official availability-search help says it ignores capitalization, spaces, periods, commas, dashes, apostrophes, ampersands, leading A/AN/THE, AND/OR/OF, and a trailing “s” when searching for similar names.
How long can I reserve a New Jersey LLC name?
For LLCs, N.J.S.A. 42:2C-10 provides a 120-day reservation period. The current LLC name-reservation fee is $50.
Why does Business.NJ.gov mention six months for name reservations?
Business.NJ.gov currently publishes a general business-name page stating six months, while the New Jersey LLC statute specifically states 120 days for an LLC name reservation. For LLCs, this guide uses the LLC-specific statutory rule and recommends confirming the current DORES filing instructions when reserving a name.
Can a New Jersey LLC use a DBA?
An established New Jersey LLC can register an alternate name. New Jersey uses the “DBA” terminology in its registration guidance primarily for out-of-state businesses whose legal name is unavailable in New Jersey.
How much does a New Jersey LLC alternate name cost?
The current New Jersey state fee is $50. The registration is effective for five years and can be renewed.
Does registering an alternate name give me exclusive rights to it?
No. New Jersey DORES specifically states that alternate-name registration does not provide exclusive rights to the name.
Do I still need to search trademarks if the NJ name is available?
Yes. New Jersey entity-name availability and federal trademark rights are separate. Use the current USPTO Trademark Search system to look for potentially conflicting federal marks.
