Searching INBiz for an Indiana business name is fast and information-rich, and Indiana stands out among its neighbors for a quietly important reason — member and manager disclosure on the Business Entity Report is genuinely optional, not mandatory.
This guide covers exactly how to search for an Indiana business or check LLC name availability in 2026 — the INBiz search tool and its multiple match modes, Indiana's distinguishability standard, name reservation and renewal, DBA registration, and what a search actually reveals (and doesn't) about ownership.
How to Search for a Business in Indiana
Use the Indiana Secretary of State — Business Services Division's INBiz Public Business Search to search for an existing business or check whether a new LLC name is available. Search by business name, business id, filing number, registered agent name, governing person (officer/manager) name. The search is free.
Search directly at bsd.sos.in.gov/PublicBusinessSearch.
INBiz gives you a choice of Contains, Starts With, or Exact Match — use "Contains" first for a broad sweep, then narrow with Exact Match once you've spotted a likely conflict. The results table is unusually information-rich compared to peer states, showing Business ID, Name, Name Type, Entity Type, Principal Office Address, Registered Agent, and Status all in one view.
Detail pages show Business ID, filing number, entity type, status, registered agent name and address, and formation date. Indiana's optional member/manager disclosure means the roster of owners may or may not appear, depending on what the entity chose to include in its Business Entity Report.
Checking Name Availability Before You File
There's no separate availability tool — applicants use the same free INBiz search, then the Secretary of State makes the final distinguishability determination when Articles of Organization or a name reservation are filed.
Indiana's Distinguishability Standard
Indiana Code §23-0.5-3-1 (part of the post-2017 Uniform Business Organizations Code) requires names be "distinguishable on the records of the secretary of state"; entity-type indicators like "LLC" or "L.L.C." are disregarded entirely when the state compares names for conflicts. INBiz is a reliable pre-check, but the Secretary of State has final say when Articles (or a reservation) are actually filed.
Reserving a Name in Indiana Before You Form
Name reservation available: For $10 base fee ($11 online with processing fee), you can reserve your chosen name for 120 days before filing.
Reserve your name for $10 ($11 if filed online) to hold it for 120 days. Unlike many states, Indiana lets you renew the reservation for successive 120-day periods rather than forcing a fresh filing once it lapses — a meaningful convenience if your formation timeline slips.
Searching for DBAs and Fictitious Names in Indiana
Indiana calls its DBA a "Certificate of Assumed Business Name," governed by Ind. Code §23-0.5-3-4. Entities (LLCs and corporations) file with the Secretary of State for $20 online or $30 by mail. Sole proprietors and partnerships instead file with the county recorder where they operate (fees vary — e.g., Marion County charges $35). Once filed, the certificate is perpetual with no renewal required.
Indiana LLC Naming Requirements
Your new LLC's name must include a designator such as "LLC" or "L.L.C.".
Restricted or regulated words require additional licensing sign-off before the Secretary of State will accept the filing, consistent with most states.
An Available LLC Name Isn't the Same as a Trademark-Safe Name
Indiana maintains its own trademark registry through the Secretary of State — $10 filing fee, three specimens required, 5-year term, with a renewal notice sent 6 months before expiration. This is a separate filing from entity name registration and provides Indiana-only protection.
INBiz and Indiana's state trademark registry only check Indiana records. Search the USPTO's Trademark Electronic Search System (TESS) separately before committing to a name, especially if you plan to operate or sell beyond Indiana.
What a Indiana Business Search Reveals
Indiana's biennial Business Entity Report makes member/manager name-and-address disclosure genuinely optional — you can leave that section blank entirely, which is a notably privacy-friendly outlier compared to states like Illinois and Maine that mandate full disclosure. INBiz searches otherwise show Business ID, filing number, entity type, status, registered agent name and address, and formation date.
Indiana does not require LLC members/owners to be listed in the public record, so a standard search will not reveal ownership information.
Getting a Indiana Certificate of Good Standing
You can confirm an LLC's good standing status and request a Certificate of Good Standing through the same INBiz Public Business Search, for $15 (no official expedite option; in-person requests are sometimes processed same day).
How to Search and Reserve Your Indiana LLC Name
If You Do It Yourself
Step 1 — Search the INBiz Public Business Search at bsd.sos.in.gov/PublicBusinessSearch.
Search by business name, business id, filing number, registered agent name, governing person (officer/manager) name to confirm your desired name isn't already taken.
Step 2 — Apply the state's distinguishability standard, not just an exact-match check.
Indiana Code §23-0.5-3-1 (part of the post-2017 Uniform Business Organizations Code) requires names be "distinguishable on the records of the secretary of state"; entity-type indicators like "LLC" or "L.L.C." are disregarded entirely when the state compares names for conflicts. INBiz is a reliable pre-check, but the Secretary of State has final say when Articles (or a reservation) are actually filed.
Step 3 — Check your name against restricted/regulated words.
Restricted or regulated words require additional licensing sign-off before the Secretary of State will accept the filing, consistent with most states.
Step 4 — Confirm your name includes a required LLC designator.
Your name must include a designator such as "LLC" or "L.L.C.".
Step 5 — Reserve your name for $10 base fee ($11 online with processing fee) if you're not ready to file yet.
Reserve your name for $10 ($11 if filed online) to hold it for 120 days. Unlike many states, Indiana lets you renew the reservation for successive 120-day periods rather than forcing a fresh filing once it lapses — a meaningful convenience if your formation timeline slips.
Step 6 — Run a separate USPTO trademark search before you commit.
INBiz and Indiana's state trademark registry only check Indiana records. Search the USPTO's Trademark Electronic Search System (TESS) separately before committing to a name, especially if you plan to operate or sell beyond Indiana.
Step 7 — File your formation documents promptly once you've confirmed availability.
If you didn't reserve the name, nothing holds it for you — another filer could take it first.
Step 8 — Watch for Indiana-specific search quirks.
Indiana's optional member/manager disclosure on the Business Entity Report is one of the more privacy-protective setups among nearby states — worth calling out explicitly if anonymity matters to you, since Illinois and Maine both mandate full disclosure. Also note that Indiana's Business Entity Report is filed biennially, not annually, which is easy to mix up when cross-referencing guides for neighboring states.

When Should You Talk to an Attorney About Your Indiana LLC Name?
Talk to an attorney before finalizing an Indiana LLC name if you're weighing whether to disclose member/manager names on your Business Entity Report, if you're registering a DBA and need to confirm whether county or state-level filing applies to your entity type, or if the name matters enough to your brand to warrant a full trademark clearance search beyond Indiana's own use-based registry.
