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

Starting a business in Indiana begins with finding and securing a business name that works for you legally and strategically. An Indiana business name search tells you whether your chosen name is already taken, meets state requirements, and whether you can move forward with registration. This guide walks you through checking name availability, reserving a name, and avoiding the mistakes that delay new business launches.

Why an Indiana Business Name Search Matters

Indiana requires that all business entity names be distinguishable from names already on file with the Secretary of State. This is not optional. If you file Articles of Organization or Articles of Incorporation with a name that is already in use, the Secretary of State will reject your filing and return your fee. Even if you have used that name on your website or marketing for months, you cannot legally register the business without approval of the name.

Beyond the legal requirement, searching early saves time and money. A rejected filing means redoing paperwork, paying new fees, and delaying your launch. A name reservation holds your chosen name for up to 120 days while you organize your business.

Materials You'll Need

Before you start, gather these materials:

  • Your preferred business name (or a list of 3 to 5 backup choices)
  • Access to a computer and internet browser
  • An email address for confirmation (if you proceed to reserve a name)
  • A credit card or bank account for the $10 name reservation fee (if reserving)
  • A copy of Indiana's business naming rules (available from the Secretary of State website)
  • Optional: notes on your business structure (LLC, corporation, partnership) to verify naming requirements

Step 1: Understand Indiana's Name Requirements

Before searching, know what Indiana requires. All LLC names must include the words "Limited Liability Company" or an approved abbreviation (LLC, L.L.C., or similar). Corporations must include "Corporation," "Corp.," "Incorporated," "Inc.," or an equivalent term. Partnerships need "Limited Partnership," "LP," or similar. Sole proprietorships may use a name with or without those identifiers.

Indiana does not allow names that are identical or confusingly similar to names already in use. The state treats certain elements as not making names distinguishable: articles (the, a, an), entity type suffixes (LLC, Inc.), punctuation, capitalization, plurals, and possessives. This means "Smith LLC" and "Smith, LLC" and "SMITH LLC" are all considered the same name. However, adding different words, letters, or numerals does make a name distinguishable, such as "Smith Properties LLC" versus "Smith & Sons LLC."

Names cannot include misleading terms. A name implying you practice medicine, law, or another regulated profession without proper licensure is prohibited. Generic names like "The Company" or "Business" are also not permitted.

Step 2: Search the Indiana Secretary of State Business Database

The Indiana Secretary of State maintains a public business search database. Follow these steps:

  1. Open your web browser and go to https://bsd.sos.in.gov/publicbusinesssearch. This is the official Indiana Secretary of State Business Services Division search tool.
  2. You will see a search box. Enter your proposed business name exactly as you plan to use it.
  3. Leave other fields (like company type or file number) blank unless you are searching for an existing business.
  4. Click the search button.
  5. Review the results. The search tool will show any businesses with names that match or are similar to your search.

If no results appear, your name may be available. However, absence from this database does not guarantee availability. Names are added as filings are processed, which can take hours. If you see a very recent date on a similar name, contact the Secretary of State office to confirm the current status.

Step 3: Do a Secondary Search for Your Specific Business Type

The public database searches all entity types together (LLCs, corporations, partnerships, etc.). To be thorough, perform a targeted search on the INBiz portal, which is the official filing system:

  1. Go to https://inbiz.in.gov/, the INBiz online filing portal.
  2. Look for a "Check Entity Availability" or "Name Search" option (the exact link name varies, but it is clearly labeled on the home page).
  3. Select your business entity type from the dropdown (LLC, Corporation, etc.).
  4. Enter your proposed name.
  5. The INBiz tool will show whether that name is available for your specific business type.

This second search is a best practice. The public database and the INBiz filing system communicate, but performing both searches gives you maximum confidence that your name is not already taken.

Step 4: Search for Trademark and Domain Conflicts (Beyond Indiana)

Indiana's business search only covers names registered with the state of Indiana. Your business name might conflict with a federal trademark or a domain name you cannot obtain. Before committing to a name, check:

  • U.S. Patent and Trademark Office (USPTO): Visit https://www.uspto.gov/ and search the trademark database. A conflicting federal trademark could legally prevent you from using your name nationwide.
  • Domain name availability: Use any domain registrar (GoDaddy, Namecheap, etc.) to check whether the .com, .net, or other domain extensions matching your business name are available. If you plan to market online, securing your domain early is important.
  • Social media handles: Check Facebook, Instagram, LinkedIn, and X (formerly Twitter) for your proposed business name. Consistency across platforms matters for brand recognition.

None of these searches are required by Indiana law, but they are practical steps that prevent future conflicts and rebranding costs.

Step 5: Reserve Your Business Name (Optional but Recommended)

Once you have confirmed your name is available, you can reserve it for up to 120 days while you organize your business. This protects the name from being claimed by someone else during your setup period. Here is how:

  1. Return to https://inbiz.in.gov/.
  2. Look for the "Reserve an Entity Name" option on the home page.
  3. Select your entity type (LLC, Corporation, etc.).
  4. Enter your desired business name, ensuring it meets the naming requirements covered in Step 1.
  5. Provide your email address and contact information.
  6. Review the terms: the reservation lasts 120 days from the date of filing.
  7. Pay the $10 name reservation fee online via credit card or bank account.
  8. You will receive a confirmation email with your reservation details and a confirmation number.

The 120 day reservation period gives you time to decide on your business structure, file your legal documents, obtain licenses, and set up bank accounts. A name reservation does not formally register your business, and it does not create any legal entity. It simply reserves the name so no one else can use it during that period.

Step 6: Document Your Reservation and Plan Your Next Steps

Once your name is reserved, save your confirmation email and reservation number. You will need this number when you file your Articles of Organization or Articles of Incorporation later. Confirm the 120 day deadline so you do not miss your filing window.

Use this reserved period to:

  • File your Articles of Organization (for an LLC) or Articles of Incorporation (for a corporation) with the Secretary of State.
  • Obtain an EIN (Employer Identification Number) from the IRS.
  • Register for state and local taxes with the Indiana Department of Revenue.
  • Purchase your domain name and set up basic web presence.
  • Decide on your registered agent and registered office address in Indiana (required for all business entities).

If you do not file your legal documents within the 120 day reservation period, the reservation expires and the name becomes available for others to use.

Tips to Avoid Common Mistakes

Mistake 1: Assuming a name is unique just because it is not in the Indiana database. Other states' databases are separate. If you plan to operate in multiple states, search those state databases too. Additionally, federal trademarks are separate, and a reserved trademark can block your Indiana registration.

Mistake 2: Choosing a name that is too close to an existing business. Even if your exact name does not appear in the search results, a name that is confusingly similar may be rejected. For example, "Smith Plumbing LLC" and "Smiths Plumbing LLC" might be considered too similar, depending on context. Err on the side of distinctiveness.

Mistake 3: Forgetting the entity type designation (LLC, Corp, etc.). If you form an LLC, your registered name must include "Limited Liability Company" or an abbreviation. Many people file assuming a generic name will work and face rejection. Verify your entity type requirement early.

Mistake 4: Not reserving the name and missing the 120 day window. A name search alone does not protect your name. You must file Articles of Organization or Articles of Incorporation within a reasonable timeframe, or someone else can register the same name. A $10 reservation buys you peace of mind and time to complete your setup.

Mistake 5: Filing with incorrect capitalization, punctuation, or spelling. The Indiana Secretary of State will file your Articles exactly as you submit them. If you write "Smiths LLC," that is your registered name, even if you meant "Smith's LLC." Proofread before submitting.

Expected Results and Timeline

When you search the Indiana business database, results appear instantly (or within seconds). A name reservation filing submitted via INBiz is processed immediately and confirmed by email, typically within a few minutes to an hour.

When you file your Articles of Organization or Articles of Incorporation, processing times vary. The Secretary of State does not publish a standard processing timeline on their website. Most filings are completed within one to five business days when filed online through INBiz, though this is not guaranteed. Expedited options are not offered for domestic LLC or corporation formations in Indiana.

Once filed and accepted, your business name is legally registered with the state of Indiana. You will receive a confirmation document (such as a file stamped copy of your Articles) via email or mail, depending on how you filed.

What to Do If Your Preferred Name Is Already Taken

If your search shows that your name is already registered:

  • Modify your proposed name slightly. Add a descriptive word, geographic location, or qualifier to make it distinguishable. "Smith Plumbing Indiana LLC" is distinguishable from "Smith Plumbing LLC."
  • Try abbreviations or alternative phrasings. "SPCO" is distinguishable from "Smith Plumbing Company."
  • Contact the current owner of the name (if it is a similar business) and ask whether they would license or sell the name. This is rare but possible for inactive or closed businesses.
  • Choose an entirely different name and repeat your search.

Do not assume you can register a nearly identical name and use "doing business as" (DBA) to operate under your preferred name. A DBA does not override Indiana's name registration rules, and it complicates your legal and tax registration.

When to Consult an Attorney or CPA

An Indiana business name search and reservation is straightforward and you can do it yourself via the Secretary of State's website. However, consider consulting a qualified professional if:

  • Your business name is similar to an existing name and you are unsure whether it would be approved.
  • You are forming a professional business (medical, legal, or other licensed practice) and need to confirm naming compliance.
  • You plan to operate in multiple states and need help with multistate trademark and name searches.
  • You are concerned about trademark conflicts and need a formal trademark search.
