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

Before you file your LLC, corporation, or partnership in New Jersey, you need to verify that your chosen business name is available. The state does not issue duplicate entity names, and a name claimed by someone else could derail your formation timeline. This guide walks you through the official New Jersey business entity search, explains what makes a name legally available, and shows you how to reserve it while you prepare your paperwork.

What You Need: Materials and Access

• Your proposed business name. Have it written down, and consider two to three alternatives in case your first choice is taken.
• Internet access and a web browser. New Jersey's name search and reservation system is entirely online.
• Credit card or debit card. A $50 name reservation fee applies if you want to lock in your name for 120 days.
• Email address. You will receive a reservation confirmation and tracking information by email.
• New Jersey street address. For reserved names and formation, you must provide a registered office address within New Jersey (a PO box alone is not acceptable).

Understanding New Jersey Name Requirements

New Jersey's Division of Revenue and Enterprise Services (DORES), part of the Department of the Treasury, maintains the official registry. Before you search, know what the state will accept:

• Entity type designator required. If you are forming an LLC, your name must include a designator such as LLC, L.L.C., Limited Liability Co., or Limited Liability Company. Corporations use Inc., Incorporated, Corp., or Corporation. Partnerships use LP (Limited Partnership) or LLP (Limited Liability Partnership). If you omit the designator, DORES will add one during filing review.
• Distinguishability rule. Your name must be distinguishable from every other business entity name already on file with the state. "Distinguishable" means it cannot be confusingly similar to an existing name, even if you use a different entity type or designator.
• No reserved words without consent. Names implying banking, insurance, or professional licensure (engineer, attorney, physician) may require proof of authority or a consent letter from the relevant regulatory body.
• Registered office address. The address you list as your registered office must be a physical street address within New Jersey. A post office box does not satisfy this requirement, though you may use a PO box for mailing if you also provide a street address.

Step 1: Access the Official Business Name Search Tool

Navigate to the New Jersey Division of Revenue business name search portal at https://www.njportal.com/DOR/BusinessNameSearch/Search/Availability. This is the only official tool for checking name availability. Do not rely on unofficial searches or third-party databases, as they do not reflect the current state registry.

You will arrive at a page labeled "Business Entity Name Search." No login is required to search for existing names.

Step 2: Enter Your Proposed Business Name and Select Entity Type

In the search box, type your business name exactly as you intend to register it, including the entity designator (LLC, Inc., LP, etc.). For example, "Riverside Consulting LLC" or "Northern Tech Solutions Inc."

Next, select your entity type from the dropdown menu:

• Limited Liability Company (LLC)
• Corporation (Domestic Business Corporation)
• Limited Partnership (LP)
• Limited Liability Partnership (LLP)
• General Partnership (GP)
• Sole Proprietorship

The state searches by entity type as well as name, so two companies with identical names can coexist if they are different entity types. However, the distinguishability rule still applies. Even if no Corporation with your name exists, your LLC with a similar name might still be rejected if it could confuse the public.

Step 3: Review the Search Results

Click the search button. The system will return results within seconds.

If your name is available: You will see a green message stating "This name appears to be available." This is not a guarantee, as DORES performs a final review when you file your formation document. However, it is a strong indicator that you can proceed.

If your name is unavailable: The system will show one or more existing entities with the same or similar name. The results display the registered business name, entity type, and filing date. At this point, return to Step 2 and try an alternative name.

Do not assume a similar name is acceptable. If the search shows "Riverside Consulting LLC" is taken, trying "Riverside Consulting Group LLC" or "Riverside Consulting Solutions LLC" may still be rejected as confusingly similar. The rule is based on how a reasonable person would distinguish the names, not just letter-by-letter differences.

Step 4: Reserve Your Name (Optional but Recommended)

Once you have confirmed your name is available, you may reserve it while you organize your formation documents. A name reservation is optional, but it is strongly recommended, especially if you are not ready to file immediately.

Navigate to the New Jersey online business formation portal at https://www.njportal.com/DOR/BusinessFormation/. From the menu, select "Reserve a Business Name." Alternatively, you can download and mail Form UNRR-1 (Application for Reservation of Business Entity Name) to DORES, though online reservation is faster.

Reservation fee: $50 per name. This is a one-time, non-refundable fee.

Reservation duration: 120 days from the date of approval. During this period, no one else can register a business with that name. You may renew the reservation for an additional 120 days by paying another $50 fee, provided you submit the renewal before your current reservation expires.

Processing time: Online reservations are typically approved within one business day and reflected in the state database almost immediately. You will receive a confirmation email with your reservation number.

Important: A name reservation does not file your business formation. It only holds the name. You must still file your Certificate of Formation (for LLCs), Certificate of Incorporation (for corporations), or partnership agreement within the 120-day window if you want to use the reserved name. After the reservation expires, the name returns to the pool of available names.

Common Mistakes to Avoid

Mistake 1: Not including the entity designator. If you search for "Riverside Consulting" instead of "Riverside Consulting LLC," the results may be inaccurate. Always include the designator in your search.

Mistake 2: Assuming a similar name is different enough. "Northern Marketing" and "Northern Marketing Group" are likely to be rejected as confusingly similar. The state applies a broad standard. If in doubt, run a search and, if there is a close match, choose a more distinct name.

Mistake 3: Treating the search result as final approval. An "available" result is not a guarantee. DORES performs a human review when you file your formation document. A name that passed the automated search could still be rejected if the state's legal team determines it is confusingly similar to an existing entity or violates state law.

Mistake 4: Skipping the reservation. If you are not filing immediately, do not assume your name will remain available. Others can claim it at any time. A $50 reservation is cheap insurance against losing your preferred name.

Mistake 5: Using the wrong address for your registered office. New Jersey requires a physical street address, not a PO box. If you use only a PO box, your formation filing will be rejected during state review. Even if you use a mailbox service, you must provide the physical street address of that service.

Tips for Choosing a Name That Will Survive the Search

Tip 1: Run multiple searches. Before you settle on a name, search for three to five variations. Test your chosen name plus common alternatives you might use for marketing. This gives you a fallback if your first choice is taken.

Tip 2: Make your name distinctive. Names that are too generic ("New Jersey Consulting") or compound common words ("Eastern North Star Advisors") are more likely to trigger distinguishability concerns or to conflict with existing entities. Include a unique element, such as the founder's name or a made-up word.

Tip 3: Check domain and social media availability at the same time. While DORES only checks business entity names in New Jersey, you should verify that your business name is available as a domain name and on social media platforms. A state-approved name that has no matching domain or is already taken on social media can weaken your online presence.

Tip 4: Reserve your name early if you are still finalizing other details. If you have confirmed your name is available but are still drafting your operating agreement or arranging your registered agent, spend the $50 to reserve the name. It buys you 120 days of peace of mind.

Tip 5: Do not try to game the system with obscure spellings. Changing "Riverside" to "Ryversyde" or using a numeral instead of a letter ("Riverside4U") does not satisfy the distinguishability rule. The state evaluates names on substance, not just spelling.

What Happens After You Reserve or File

Once your name is reserved, you have 120 days to file your formation document. When you submit your Certificate of Formation, Certificate of Incorporation, or partnership agreement through the NJ Business Portal, reference your reservation number. The state will apply your reserved name to your new entity.

After your formation is approved and your entity is live, your business name is registered with DORES and will appear in future searches. You are now the owner of that business entity name in New Jersey.

If you do not file within 120 days, your reservation expires. The name is released, and someone else could register it. You would then need to search again and start over.

Related Formation Steps

Securing your business name is only the first step. After your name is reserved and before you file your formation, you will also need to:

• Choose and appoint a registered agent (a person or business entity authorized to receive legal notices on behalf of your company in New Jersey)
• Identify your registered office address (the physical street address where legal documents will be delivered)
• Prepare your formation document (Certificate of Formation for an LLC, Certificate of Incorporation for a corporation, etc.)
• File your formation document with DORES (typically $100 filing fee for an LLC or corporation, plus any expedited-service fee if desired)

Frequently Asked Questions

Q: Can I search for business names on behalf of someone else?
A: Yes. The NJ name search tool is public and requires no login. Anyone can search to check availability. However, only the person or entity filing the formation can reserve a name or register an entity.

Q: What if someone registers my business name while my reservation is pending?
A: Once your reservation is approved and issued, no one else can register that name during the 120-day reservation period. Your reservation takes priority. If you have not yet submitted your reservation, the name is not protected.

Q: Do I need a registered agent to reserve a business name?
A: No. A name reservation requires only the proposed name and the $50 fee. You do not need to identify a registered agent or registered office for a reservation. However, you will need both before you file your formation document.

Q: Can I change my business name after I file?
A: Yes, but it requires an amendment to your formation document and a filing fee. The amended name must pass the same availability and distinguishability checks as a new name. It is simpler to get the name right the first time.

Q: Is a business name search required in every New Jersey county?
A: No. New Jersey business entities are registered only with the state (DORES), not with individual counties. A statewide search through the official portal is sufficient. However, if you operate under an assumed or alternate name (a "DBA" or "Doing Business As"), you may need to register that name with your county clerk as well.
