Searching for an available LLC name in Indiana is a required step before submitting your Articles of Organization to the Indiana Secretary of State. The INBiz business name database reflects all active, inactive, and reserved entity names on file with the state, giving you a real-time snapshot of what is already claimed. Running a search lets you confirm whether your proposed name is distinguishable from existing registered businesses. Keep in mind that a name appearing as "available" in the database does not guarantee the state will approve it — the Secretary of State makes the final determination when you file. A name that passes the search can still be rejected if it is deemed too similar to an existing name under Indiana's distinguishability standards. Searching thoroughly before filing saves time and prevents costly refiling fees.
Step-by-step: using the Indiana Secretary of State name search
- 1. Go to the Indiana Secretary of State's INBiz business search portal at https://inbiz.in.gov/BOS/BusinessSearch/BusinessSearch.
- 2. In the 'Business Name' field, type your proposed LLC name. You can search by full name or partial keyword. Leave the entity type filter set to 'All' on your first search, then narrow to 'Limited Liability Company' to see only LLCs.
- 3. Click the 'Search' button to retrieve results. The system will display a list of entities with matching or similar names, along with their entity type, status (Active, Inactive, Withdrawn, etc.), and formation date.
- 4. Review each result carefully. Pay attention to names that are phonetically similar, use alternate spellings, or swap common words (e.g., 'and' vs '&'). Indiana requires your name to be distinguishable from all results, not just exact matches.
- 5. If your proposed name returns no conflicting results and appears distinguishable from everything listed, you may proceed to file your Articles of Organization or submit a name reservation through INBiz to hold the name for up to 120 days.

Indiana LLC naming rules
- Your LLC name must contain the words 'Limited Liability Company,' the abbreviation 'LLC,' or 'L.L.C.' — one of these designators is required in every Indiana LLC name.
- The name must be distinguishable upon the records of the Indiana Secretary of State from any other business entity name already on file, including corporations, LLPs, and other LLCs.
- Your name cannot contain language that implies the LLC is organized for a purpose other than what is permitted for an LLC under Indiana law.
- Words suggesting government affiliation — such as 'Federal,' 'State,' 'United States,' or any Indiana agency name — are prohibited unless you have explicit written authorization.
- Restricted professional terms including 'Bank,' 'Banking,' 'Trust,' 'Insurance,' 'Engineer,' 'Architecture,' and similar regulated-industry words require prior approval from the applicable Indiana state regulatory agency.
- The name cannot include obscene, offensive, or misleading language that would deceive the public about the nature or legitimacy of the business.
- Terms such as 'University,' 'College,' or 'Institute' typically require authorization from the Indiana Commission for Higher Education before use in a business name.
- Numerals and symbols are generally permitted but must be considered as part of the distinguishability analysis — '4' and 'Four' may be treated as equivalent when comparing names.
Restricted words in Indiana LLC names
The following words require special approval from a state agency before you can use them in your Indiana LLC name:
- Bank / Banking / Banker — requires approval from the Indiana Department of Financial Institutions
- Insurance / Insurer / Assurance — requires approval from the Indiana Department of Insurance
- University / College / Institute — requires authorization from the Indiana Commission for Higher Education
- Trust / Trustee — requires approval from the Indiana Department of Financial Institutions
- Engineer / Engineering / Surveyor — requires licensure verification from the Indiana Professional Licensing Agency
- Attorney / Law / Legal Services — use with caution; may imply a law firm and require bar authorization
- Federal / National / State / United States — cannot imply government sponsorship or affiliation without written authorization
- Cooperative / Co-op — subject to additional scrutiny and may require filing under a separate Indiana statute
How to reserve an LLC name in Indiana
Indiana allows you to reserve an LLC name before filing by submitting a Name Reservation application through the INBiz portal or by mail. The filing fee is $10. Once approved, the reservation holds your chosen name exclusively for 120 days. Reservations are not automatically renewable, but you may file a new reservation after the period expires if the name is still available. The reservation is transferable to another person or entity by filing a notice of transfer with the Secretary of State.
Tips for choosing an LLC name that passes in Indiana
- Search for both exact spellings and common variations — swap plurals, abbreviations, and phonetic equivalents to catch names the state may consider confusingly similar to yours.
- Run a federal trademark search on the USPTO's TESS database (tmsearch.uspto.gov) to ensure your chosen name does not infringe on a registered trademark, which the Indiana SOS search will not catch.
- Check domain name availability for your LLC name at the same time — securing a matching .com domain early protects your brand even if it is not legally required.
- Avoid highly geographic names (e.g., 'Indianapolis Tech LLC') unless your business is permanently local; geographic descriptors can limit expansion and may conflict with other entities using the same location name.
- Choose a name that reflects your business purpose broadly enough to accommodate future growth — an overly narrow name may require a formal amendment if your services expand.
- Consider doing a Google search and a social media handle search for your proposed name to identify any unregistered businesses already using it, reducing the risk of common-law trademark conflicts even if the state search shows it as available.
Indiana LLC name search: frequently asked questions
How do I do an Indiana LLC name search?
You search for Indiana LLC names through the INBiz business search portal at https://inbiz.in.gov/BOS/BusinessSearch/BusinessSearch. Enter your proposed name in the search field and review the results for any entities with the same or similar names. You can filter by entity type to focus on LLCs specifically. The search is free and available to the public at any time.
How do I check LLC name availability in Indiana?
To check availability, search the INBiz database and look for existing entities with identical or distinguishably similar names. A name with no matches is a strong signal it may be available, but the Secretary of State makes the final call when you file. If you want to lock in a name before filing, submit a $10 name reservation through INBiz, which holds it exclusively for 120 days. Checking domain availability and federal trademarks alongside the state search gives you a fuller picture.
What are Indiana's LLC naming rules?
Indiana requires every LLC name to include 'Limited Liability Company,' 'LLC,' or 'L.L.C.' as a designator. The name must be distinguishable from all other business entities already on file with the Secretary of State. Certain words — such as Bank, Insurance, University, and Engineer — require prior approval from the relevant state regulatory agency. Names that imply government affiliation or contain obscene or misleading language are prohibited.
How do I reserve an LLC name in Indiana?
You can reserve an Indiana LLC name by filing a Name Reservation application through the INBiz portal or by mailing the form to the Secretary of State's office. The reservation fee is $10 and the reservation lasts 120 days. The reservation can be transferred to another party by notifying the Secretary of State. After 120 days, you can file a new reservation if the name is still available.
What should I do if my LLC name is already taken in Indiana?
If your preferred name is taken, you have several options: add a unique word or descriptor to make the name distinguishable, use a different spelling or phrasing that achieves a similar brand effect, or choose an entirely different name. You can also contact the existing entity to explore purchasing or licensing rights to the name, though the Secretary of State is not involved in that negotiation. If the existing entity is inactive or dissolved, you may still be prevented from using the name — check the entity's status carefully and consider consulting an attorney.
Does an Indiana LLC name need to include 'LLC'?
Yes. Indiana law requires every LLC name to include one of the following designators: 'Limited Liability Company,' 'LLC,' or 'L.L.C.' Omitting a designator will result in rejection of your Articles of Organization. The designator must appear as part of the official legal name on all state filings, though Indiana does allow you to operate under a trade name (DBA) that does not include the designator for day-to-day business use.
