Hawaii Business Name Search: How to Check and Reserve a Name

Before you file your LLC or corporation in Hawaii, you need to claim a business name. Unlike incorporating, which costs $50, a hawaii business name search is free, but reserving one costs $10. Getting this step right saves you from discovering weeks later that your chosen name is already taken, or filing paperwork with a name that fails compliance checks.

This guide walks you through searching, understanding Hawaii's specific naming rules, and reserving your name through the official Hawaii Business Express system.

Why You Need to Check Your Business Name First

Checking availability before incorporation or LLC filing serves multiple purposes. First, Hawaii does not allow substantially identical names within the state registry. Filing an LLC with a name that duplicates an existing business leads to rejection by the Hawaii Department of Commerce and Consumer Affairs, Business Registration Division (BREG). Second, a name reservation gives you 120 days of exclusive legal claim to that name, so you can complete other startup steps without someone else grabbing it. Third, understanding naming rules upfront prevents the frustration of filing paperwork only to have BREG return it with corrections requested.

Materials You'll Need

  • A web browser and internet access
  • Your preferred business name (or a short list of alternatives)
  • A payment method if you decide to reserve the name (the $10 reservation fee accepts credit cards online)
  • A clear understanding of Hawaii's naming requirements, which are outlined below

Step 1: Understand Hawaii's Business Naming Rules

Hawaii has specific rules for what you can name your business. Violating these rules means BREG will reject your name during search or filing.

Legal structure designators: If you are forming a limited liability company (LLC), your name must include one of the following at the end:

  • "Limited Liability Company"
  • "L.L.C." (with periods)
  • "LLC" (without periods)
  • "Limited" or "Ltd." (an allowed abbreviation)
  • "Company" or "Co." (an allowed abbreviation)

If you are forming a corporation, your name must include "Corporation," "Corp.," "Incorporated," "Inc.," or a similar designation. This matters because the search rules differ slightly by entity type, so know which structure you are forming before you search.

Prohibited words and uniqueness: Your name cannot be substantially identical to a name already registered with the Hawaii Department of Commerce and Consumer Affairs. This is checked against all business types (LLCs, corporations, trade names, limited partnerships, and others). Hawaii statutes Section 428-105, HRS and Section 16-36-15, Hawaii Administrative Rules define "substantially identical."

While Hawaii does not maintain a published list of banned words (like some states do), courts and regulators scrutinize names that suggest activities you are not licensed for. For example, a name implying you are a bank, insurance company, or licensed professional is rejected if you do not hold that license. Profane, offensive, or explicitly political names face administrative review on a case-by-case basis.

Step 2: Visit the Hawaii Business Express Portal and Search for Availability

BREG has moved its entire business filing system to Hawaii Business Express (HBE), the state's online portal. This is where you perform a hawaii business entity search.

  1. Go to https://hbe.dcca.hawaii.gov/search-and-buy in your web browser.
  2. You will see a search box. Enter your proposed business name exactly as you intend to file it, including any LLC/Corp. designation.
  3. Click the "Search" button. The system will display any existing businesses with identical or substantially similar names.
  4. Review the results. If your proposed name appears with an existing business, it is not available. If no results appear, your name is likely available. Note the word "likely": unavailability is ultimately BREG's decision when you file, not the search tool's, though false positives are rare.
  5. If your first choice is taken, adjust the name (change a word, reorder terms, or pick an alternative) and search again. You can perform as many searches as needed. This process is free and unlimited.

The search tool looks across all entity types and all historical records, including inactive entities. A name that appears as "dissolved" or "withdrawn" may still be unavailable if BREG has not yet released it back into the pool. If you are unsure whether a result means your name is blocked, the BREG FAQ provides guidance, or you can contact BREG directly through their website.

Step 3: Reserve Your Business Name (Optional but Recommended)

Once you have confirmed that your desired name is available, you have two paths: proceed directly to filing your articles of organization or incorporation, or reserve the name first.

Why reserve a name: A name reservation costs $10 and locks the name for 120 days. This gives you 4 months to complete other startup tasks (securing funding, finalizing your business plan, consulting an attorney) without risk that someone else will register the same name. If you are moving quickly toward filing, reservation may be unnecessary. If you are still planning and may take months before filing, reservation provides peace of mind.

How to reserve:

  1. Return to https://hbe.dcca.hawaii.gov/ (the main portal, not the search tool).
  2. Log in or create a new Hawaii Business Express account if you do not already have one. The account is free and required to file online.
  3. Select "File a Document" and choose "Name Reservation."
  4. Enter your proposed business name, select your entity type (LLC, Corporation, etc.), and provide a contact email address.
  5. Review the details and proceed to payment. Pay the $10 reservation fee with a credit card.
  6. After payment, you will receive a confirmation number and an email receipt. This email includes your reservation number and the date it expires (120 days from filing).

Keep your confirmation number and receipt. You will not need to reference the reservation when you file your full articles, but it serves as proof that you held the name during the reservation period if a question arises.

If you decide not to use the reserved name or do not file your articles before the 120 days expire, the reservation lapses automatically and the name returns to the available pool. BREG does not issue refunds for unused reservations.

Step 4: Note the Name Requirements and Check Them Against Your Filing Documents

Before you file your articles of organization or articles of incorporation, confirm that:

  • Your name appears exactly as it did during the search and reservation (if applicable).
  • The legal designator (LLC, Inc., etc.) matches your chosen entity type.
  • The name is not substantially similar to any name you saw during your search.
  • You have not altered the name in a way that might trigger compliance issues. For example, if you reserved "Smith Tech Solutions LLC," your articles must state "Smith Tech Solutions LLC," not "Smith Tech Solutions, LLC" (with an extra comma) or "Smith Technology Solutions LLC" (a different word).

This step prevents the frustration of BREG returning your filing with a notice that the name does not match what you searched, or that the name now appears to conflict with another entity registered during your planning period.

Common Mistakes to Avoid

Mistake 1: Forgetting the legal designator. Your name must include LLC, Inc., or an equivalent. A name like "Smith Tech Solutions" is incomplete. "Smith Tech Solutions LLC" is correct. Omitting this when you file will result in BREG requesting a correction.

Mistake 2: Assuming a similar name is different enough. "Smith Tech Solutions LLC" and "Smith Technologies Solutions LLC" may sound different to you, but BREG's "substantially identical" rule is strict. If you are unsure, search the similar name too. A few extra searches cost nothing and prevent delays.

Mistake 3: Searching a different version than you intend to file. If you search "Smith Tech Solutions LLC" but plan to file "Smith Tech Solutions, Inc.," you are searching the wrong entity type. Search with the exact designation and structure you plan to use.

Mistake 4: Reserving a name and then changing it without notifying BREG. You do not need BREG's permission to use a different name when you file, but if you reserved "Smith Tech Solutions LLC" and then file "Smith Analytics LLC," the reservation for the first name is wasted. Plan your final name before you reserve.

Mistake 5: Assuming a free search is complete legal validation. The search tool checks for duplicates in the state registry, but it does not check for trademark conflicts, domain name availability, or whether your name complies with federal naming rules (if you plan to register as an S-corp with the IRS, for instance). A free BREG search is necessary but not sufficient. After confirming state availability, consider searching the USPTO trademark database and checking domain availability if your business operates online.

Mistake 6: Waiting too long to file after reservation. Your 120-day reservation runs out whether you file or not. Mark your calendar 90 days out as a reminder to either file your articles or reserve again if needed.

Expected Timeline and Results

Searching for availability: Instant. Results display within seconds.

Reserving a name: The reservation is effective immediately after payment. You will receive a confirmation email within a few minutes. The reservation period begins the day you file it and runs for exactly 120 calendar days.

What to expect after filing your articles: After you file your LLC articles of organization or corporation articles of incorporation with the name you searched, BREG will process the filing and approve or request corrections. Processing time varies. BREG does not publish a standard turnaround time for routine filings. Online filing through Hawaii Business Express is described by BREG as the most efficient method. In practice, routine filings are processed within 5 to 10 business days, though this is not guaranteed. If you need faster processing, BREG normally offers expedited review for an extra $25.00, but BREG has stated that expedited processing is not available at this time following the July 6, 2026 move to the new Hawaii Business Express system. Only routine processing is being offered.

Once your articles are approved, your business name is officially registered with Hawaii. You will receive a confirmation and a file number. This is your proof of registration for later steps, such as opening a business bank account, obtaining an Employer Identification Number (EIN) from the IRS, and applying for licenses.

Next Steps After Your Name is Reserved or Registered

A name search and reservation are the first step, not the final one. After you confirm your name is available and reserved, your checklist includes:

  • Filing your articles of organization (LLC) or articles of incorporation (corporation) with BREG, using the same name you searched and reserved.
  • Registering for a Hawaii General Excise Tax (GET) license with the Hawaii Department of Taxation. This is required for nearly all businesses in Hawaii and costs $20 as a one-time fee, plus ongoing filing obligations.
  • Obtaining an Employer Identification Number (EIN) from the IRS if you plan to hire employees or operate as a partnership or corporation. This is free and can be done online.
  • Checking whether your industry requires state professional or vocational licenses (e.g., contractor, real estate agent, health care provider).
  • Registering your domain name if you operate online, to protect your brand.
  • Opening a business bank account in your registered business name.

For guidance on these steps, consult the Hawaii Small Business Development Center at https://hisbdc.org/ or speak with a business attorney and accountant. BREG's site at https://cca.hawaii.gov/breg/ also maintains FAQ and guidance documents specific to each filing type.

Key Takeaways

Checking and reserving your Hawaii business name is a straightforward but essential step. Use Hawaii Business Express to search for free, confirm that your chosen name is not substantially identical to any existing entity, and decide whether to reserve the name for $10 and 120 days of exclusivity. Avoid common pitfalls like omitting the legal designator, changing your name between search and filing, or assuming a free search validates trademark or domain availability. Once your name is locked in and your articles are filed, you can move forward with confidence on the other startup requirements.
