How Business Name Availability Works in Indiana
Indiana consolidated everything into INBiz (inbiz.in.gov) — the state's one-stop portal covering the Secretary of State's name search, name reservations, entity formations, and assumed-name filings. The business search is free and covers LLCs, corporations, reserved names, and assumed business names registered by entities.
Naming follows Indiana's uniform business code: under IC 23-0.5-3-1, an LLC name must contain "limited liability company," "L.L.C.," or "LLC," and under IC 23-0.5-3-4 it generally must be distinguishable on the Secretary of State's records from every existing and reserved name. Corporations need "corporation," "incorporated," "company," or "limited" or an abbreviation. A reservation holds a name for 120 days, filed through INBiz — around $10 online or $20 by mail, but confirm the current fee in the portal before filing.
Indiana's DBA system runs on two tracks. Registered entities file an Assumed Business Name with the Secretary of State through INBiz; sole proprietors and general partnerships instead record theirs with the county recorder of each county where they do business. Formation itself is affordable — $95 for an LLC — and Indiana asks for a business entity report only every other year, at $32.

How to Check Name Availability in Indiana
Use the tool above to open the Indiana Secretary of State — INBiz Business Search search and look up existing LLCs, corporations, and reserved names. INBiz is Indiana's single front door — name searches, reservations, formations, and assumed-name filings for registered entities all run through one portal, and LLCs report only every other year with a $32 biennial business entity report.
Search the USPTO database at uspto.gov — clearing the Indiana registry does not protect you from a federal trademark claim.
Check that the matching .com domain is available before you commit — renaming an LLC later means an amendment filing and new bank paperwork.
Confirm your name is free on Instagram, X, Facebook, and LinkedIn so your branding stays consistent everywhere.

Frequently Asked Questions
How do I check if a business name is taken in Indiana for free?
Search the Secretary of State's business database through INBiz at inbiz.in.gov — it is free and covers Indiana LLCs, corporations, reserved names, and assumed business names filed by registered entities. It does not include assumed names recorded by sole proprietors at county recorder offices, so check the recorder in each county where you plan to operate, then finish with a web and USPTO trademark search.
How much does it cost to reserve a business name in Indiana?
An Indiana name reservation holds a name for 120 days and is filed through INBiz under Online Services, then Name Reservations. The fee is around $10 online or $20 by mail, but confirm the current amount in INBiz before filing, and note that whether a reservation can be renewed is not clearly stated — treat the 120 days as your working deadline and plan the formation filing inside it.
What suffix does an Indiana LLC name need?
Under Indiana Code § 23-0.5-3-1, an Indiana LLC name must contain "limited liability company," "L.L.C.," or "LLC." Corporations must include "corporation," "incorporated," "company," or "limited," or an abbreviation of one of those words. The name also generally must be distinguishable on the Secretary of State's records from existing and reserved names under IC 23-0.5-3-4.
How do assumed business names work in Indiana?
Indiana uses a dual track. LLCs and corporations file a Certificate of Assumed Business Name with the Secretary of State through INBiz, at around $20 online or $30 on paper. Sole proprietors and general partnerships instead file with the county recorder in each county where they do business — there is no state filing for them. In both cases the registration is public notice only and grants no exclusive rights to the name.
Does Indiana require an annual report for LLCs?
Not annual — biennial. Indiana LLCs file a business entity report every two years, at $32 when filed online through INBiz. That every-other-year rhythm, combined with the modest $95 formation fee, makes Indiana one of the lower-maintenance states for keeping an LLC in good standing. Miss the report, though, and the state can administratively dissolve the LLC, so calendar the due date.
What is INBiz?
INBiz (inbiz.in.gov) is Indiana's single online portal for business filings. It combines the Secretary of State's free business search with name reservations, entity formations, assumed business name filings for registered entities, and biennial business entity reports. Instead of hunting across separate agency sites, Indiana founders do essentially everything — from checking a name to maintaining the LLC — inside the one system.

Searching Indiana Business Names Through INBiz
INBiz wraps the Secretary of State's business search in the same portal you will later use to file. The search is free and shows entity status, formation dates, registered agents, and filing histories — plus assumed business names registered by LLCs and corporations.
The blind spot is the county track: assumed names recorded by sole proprietors and general partnerships live at each county recorder's office, not in INBiz. If your market is local, a call to the recorder in your county (and neighboring ones) closes the gap; a web and USPTO trademark search covers the rest.
When the name is clear, reserve it for 120 days through INBiz (Online Services, then Name Reservations) or file the Articles of Organization directly for $95 — formation is what actually secures the name.
Indiana Naming Rules Under IC 23-0.5
Indiana's Uniform Business Organizations Code puts naming rules for all entity types in one place. An LLC name must contain "limited liability company," "L.L.C.," or "LLC" (IC 23-0.5-3-1); a corporation needs "corporation," "incorporated," "company," or "limited" or an abbreviation. The distinguishability test in IC 23-0.5-3-4 is the familiar one: generally, your name must differ in some recognizable way from what is already on the Secretary of State's records.
As elsewhere, cosmetic changes rarely help — punctuation, spacing, capitalization, or a different designator will not make "Hoosier Consulting LLC" distinguishable from "Hoosier Consulting Inc." Change a key word instead.
Regulated words route through regulators: banking, trust, savings, and credit-union terms generally require Department of Financial Institutions approval, and insurance wording is typically reviewed under Department of Insurance rules.
Indiana's Dual-Track Assumed Business Names
Which office takes your DBA depends on what you are. Registered entities — LLCs, corporations, LPs — file a Certificate of Assumed Business Name with the Secretary of State through INBiz, at around $20 online or $30 on paper (confirm current fees in the portal). The filing appears in the same searchable database as the entity itself.
Sole proprietors and general partnerships take the other track: they file their assumed business name with the county recorder in each county where they do business. There is no state-level registration for them, which is why county records matter when you are checking whether a name is truly free.
Neither track grants exclusivity — an assumed name is public notice of who stands behind a trade name, nothing more. For real protection, form the entity under the name or pursue a trademark. And note the reporting rhythm once you form: Indiana LLCs file a business entity report every two years ($32 online), one of the lighter compliance loads in the country.
