A Texas LLC name availability search tells you whether your desired business name is already taken in the state's records. There are three ways to do it — a free search via the Texas Comptroller, a paid search via SOSDirect, and a free inquiry by phone or email directly to the Secretary of State.

1

Start with the Free Comptroller Search

Go to the Texas Comptroller Taxable Entity Search at comptroller.texas.gov. No account needed, no fee. Type your desired LLC name and search. Results show all matching registered entities with their name, status, and zip code. This is the fastest way to do a free LLC name search in Texas and should always be your first step. Use our free Texas LLC name search tool →

2

Search SOSDirect for a Deeper Check

The Texas SOS LLC name availability search via SOSDirect is the official state database — it includes inactive entities, reserved names, and assumed names that the Comptroller search may miss. Create a SOSDirect account at direct.sos.state.tx.us and pay $1 per search. The Texas SOSDirect name availability search LLC tool is the most comprehensive check available before you file.

3

Get a Free Preliminary Clearance (Optional)

You can email the SOS Corporations Section at corpinfo@sos.texas.gov or call (512) 463-5555 for a free preliminary check. The SOS will tell you whether your desired name appears available. Important: this is informal — a final determination only happens when you submit your actual filing. Don't spend money on anything else based solely on a phone clearance.

4

Search the USPTO for Trademarks

A name available in the Texas SOS database can still be protected by a federal trademark. Before committing to any name, run a free search at USPTO.gov. If someone holds a trademark on a confusingly similar name in your industry, using it creates legal risk even if the SOS approves your filing.

5

Check Domain Names and Social Handles

Even if the SOS approves your LLC name, you'll also want matching domain and social media availability. Check .com domain availability and Instagram, Facebook, LinkedIn before you file — discovering your domain is taken after formation is a frustrating detour.

Free vs. Paid Texas LLC Name Search Options

For most entrepreneurs doing a Texas LLC business name search, the free Comptroller tool is sufficient to get started. But the paid SOSDirect search is more thorough. Here's when each makes sense.

Feature Texas Comptroller Search SOSDirect Search
Cost Free $1 per search
Account required No Yes
Active LLCs and corporations
Inactive/forfeited entities Partial Full
Reserved names
Assumed names (DBAs) Partial Full
Foreign entities (out-of-state) Partial
Best for Quick first check Definitive pre-filing check
Start with the free Texas LLC name search via the Comptroller. If your name looks clear there, follow up with the $1 Texas SOS LLC name search before filing your Certificate of Formation. The $1 is the cheapest possible insurance against a $300 rejection.

You can also do a Texas LLC search by name or by file number via SOSDirect. For owner-based lookups, the Texas LLC search by owner name feature on SOSDirect lets you search entities by their member or officer names — useful when you're researching competitors or verifying a partner's existing business history.

Texas LLC Naming Rules in 2026

Texas LLC naming rules are governed by the Texas Business Organizations Code (BOC) §5.053–5.056 and Texas Administrative Code, Title 1, Part 4, Chapter 79, Subchapter C. These rules apply to every LLC name search in Texas and every Certificate of Formation filing. Violating any of them is an immediate rejection.

Texas LLC Naming Rules — What's Required
✓
Must include an LLC designator Your name must end with one of the approved designators: "Limited Liability Company," "Limited Company," "LLC," "L.L.C.," "LC," "L.C.," "Ltd. Liability Co.," or "Ltd. Liability Company." Using "LLC" is most common and universally accepted.
✓
Must be distinguishable from all existing Texas entities Under BOC §5.053, your name must be distinguishable from every existing filing entity, foreign entity registered in Texas, reserved name, and fictitious name in the SOS database. "Similar" isn't good enough — it must be clearly distinguishable. See detailed rules below.
✓
Can use Roman letters, numbers, and certain symbols Allowed symbols include: ! " $ % ' ( ) * ? # = @ [] / + & –. Subscript and superscript aren't recognized (CO₂ becomes CO2 in the database). Font, capitalization, and styling differences don't matter — all names normalize to plain text.
✗
Cannot imply government affiliation Names suggesting federal or state government connection — "Texas State Department LLC," "Federal Bureau LLC," "US Government Services LLC" — are rejected without prior agency approval.
✗
Cannot imply banking or insurance without authorization Words like "Bank," "Trust," "Trust Company," or "Insurance" require written authorization from the Texas Banking Commissioner or relevant state agency before filing. See the restricted words section below.
✗
Cannot imply illegal activity or be grossly offensive Self-explanatory. The SOS rejects names that suggest criminal enterprise or that reasonable people would find deeply offensive. "Bail Bond" is also specifically prohibited in LLC names.

What Makes a Texas LLC Name "Distinguishable"?

The most misunderstood part of any Texas LLC name availability search is the "distinguishable" standard. The Texas SOS doesn't just block exact matches — it blocks names that aren't sufficiently different. Understanding what does and doesn't create distinguishability is the key to avoiding rejection. Punctuation and capitalization do not make a name distinguishable; our LLC punctuation guide covers the details.

This Does NOT Create Distinguishability Example Result
Different designator (LLC vs Inc vs Corp) "Austin Bakes LLC" vs "Austin Bakes Inc." Same name
Different capitalization "Sunflower Studio LLC" vs "SUNFLOWER STUDIO LLC" Same name
Adding articles ("The," "A," "An") "A Coffee House LLC" vs "Coffee House LLC" Same name
Adding plural "s" "Texas Builders LLC" vs "Texas Builder LLC" Usually same
Adding conjunction ("And," "Or," "&") "Mountains Climbing LLC" vs "Mountains and Climbing LLC" Same name
Different punctuation "Mike's Bikes LLC" vs "Mikes Bikes LLC" Same name
This DOES Create Distinguishability Example Result
Different key words "Austin Web Design LLC" vs "Austin Digital Strategy LLC" Distinguishable
Different word order (with meaning change) "Summit Energy LLC" vs "Energy Summit LLC" Distinguishable
Different root words "Great Products LLC" vs "Great Productions LLC" Distinguishable
Words in different language (same meaning) "Casa Blanca LLC" vs "White House LLC" Distinguishable
Adding meaningful geographic qualifier "Real Homes LLC" vs "Real Homes of Austin LLC" Distinguishable
Different homophones (written differently) "Knight Services LLC" vs "Night Services LLC" Usually OK
The Gray Zone The SOS has discretion. Some names that look distinguishable to you may not pass the reviewer's judgment. A name like "Texas Car Wash LLC" vs "Texas Carwash LLC" could go either way. When in doubt, call the SOS at (512) 463-5555 for a free preliminary check — or run the full Texas LLC name availability search through SOSDirect before committing.

Restricted Words That Require Special Approval

Some words can be used in a Texas LLC name — but only with prior written authorization from a specific state agency. Using them without approval causes immediate rejection of your Texas LLC name search results and your Certificate of Formation filing.

Restricted Word/Topic Requires Approval From
Bank, Trust, Trust Company Texas Banking Commissioner
Insurance, Insure, Assurance Texas Department of Insurance
College, University, Law School, Seminary, Medical School Texas Higher Education Coordinating Board
Architect, Architecture, Interior Design Texas Board of Architectural Examiners
Engineer, Engineering Texas Board of Professional Engineers
Surveying, Surveyor Texas Board of Professional Land Surveying
Veteran, Legion, Foreign, Disabled, War Congressionally recognized Veterans' organization
Olympic, Olympiad, Olympian, Olympus U.S. Olympic Committee
Bail Bond Prohibited entirely in LLC names
Using any of these restricted terms without prior authorization is an automatic rejection — no refunds. Get written authorization from the applicable agency before you file. Keep that authorization letter ready to include with your Certificate of Formation.

What Gets a Texas LLC Name Rejected

Every llc name search in texas that uncovers a potential conflict is a warning. These are the actual reasons the SOS rejects LLC names — in order of frequency.

  • Name isn't distinguishable from an existing entity. This is a common rejection cause. The SOS checks your proposed name against every active entity, inactive entity, reserved name, and assumed name. Adding "The," changing capitalization, or using a different designator doesn't save you.
  • Missing required LLC designator. Submitting "Austin Brand Studio" without "LLC" or another accepted designator is an automatic rejection. The designator must appear in the legal name exactly as filed.
  • Using a restricted word without authorization. Submitting "Austin Trust Services LLC" without Banking Commissioner approval — rejected. No exceptions, no appeals process.
  • Name implies government affiliation. "Texas State Business Authority LLC," "US Federal Consulting LLC," "National Bureau of Services LLC" — all rejected. The SOS is very sensitive to any name that might mislead the public into thinking the business is a government entity.
  • Name clashes with a reserved name. If another entrepreneur reserved your desired name before you filed, you're blocked — even if they haven't formed their LLC yet. The Comptroller search doesn't show reservations. Only SOSDirect Texas LLC name search reveals reserved names.
The Real Cost of a Rejected Name Texas's $300 filing fee is non-refundable. A rejected name forces you to correct it and pay $300 again. That's why running a thorough Texas LLC name availability search before filing is never optional — it's the single most effective way to protect your $300.

How to Reserve an LLC Name in Texas

If you're not ready to file your LLC immediately but don't want someone else to claim your desired name, you can reserve it. Texas name reservations are "generic" — a reservation made for an LLC can later be used to form any type of entity (LLC, corporation, LP, etc.).

A name reservation doesn't guarantee trademark protection — it just prevents other businesses from filing the same name in Texas during your 120-day window. File your LLC during that period to make it permanent. See Certificate of Formation guide →
Should you reserve? Only if you're not ready to file immediately. If you can file within the next week or two, skip the $40 reservation and file directly. The Comptroller search takes minutes — if your name is clear, just move straight to filing.

Can Two Texas Businesses Have Similar Names?

Sort of — but there are important nuances. The SOS will reject your LLC name if it's not sufficiently distinguishable from an existing entity's legal name. However, two businesses can use the same assumed name (DBA). And foreign-language versions of the same English name are often considered distinguishable.

Name Conflict Scenarios — What Happens
✗
Same name, different designator → Rejected "Austin Auto Parts LLC" cannot be filed if "Austin Auto Parts Inc." already exists. Different designators don't make names distinguishable under Texas law.
✗
Name already reserved → Blocked If someone filed Form 501 to reserve "Lone Star Digital LLC" three weeks ago, your identical filing gets rejected — even if they haven't formed the LLC yet. Only SOSDirect reveals reserved names.
✓
Same assumed name (DBA) → Usually allowed Unlike LLC legal names, assumed names (DBAs) are notice filings without exclusivity. Multiple businesses can register the same DBA name. The SOS doesn't check for DBA conflicts the way it does for LLC legal names.
✓
Consent from existing entity → May be accepted If your desired name isn't distinguishable from an existing entity but you obtain written consent from that entity, the SOS may accept your filing. This is uncommon but specifically allowed under Texas naming guidelines §79.40.
~
Same profession, different qualifiers → Often OK "John Smith Construction LLC" and "John Smith Hair Design LLC" are distinguishable because of the different industry qualifiers. You can use common surnames or words as long as meaningful differentiating words are present.

For using a name different from your LLC's legal name, see our Texas DBA (Assumed Name) guide →

Naming Tips for Approval Success

A thoughtful approach to your Texas LLC name search before filing eliminates most rejection risk. These aren't legal requirements — they're practical strategies that experienced filers use to get names approved on the first try.

  • ✓
    Always run a Texas state LLC name search before filing — not after. The $300 filing fee is non-refundable. Do the free Texas LLC name search via the Comptroller first, then the $1 SOSDirect check. Two minutes and $1 can save you $300 and weeks of delay.
  • ✓
    Add a geographic or industry qualifier that has real meaning. "Austin Creative Design LLC" is more likely to be distinguishable than "Creative Design LLC" — because the geographic qualifier meaningfully differentiates it. Make sure the qualifier isn't just filler.
  • ✓
    Search variations of your name — not just the exact version. Do your Texas LLC name search with and without articles, with plurals and singulars, with common abbreviations. If "Summit Energy" is taken, "Summit Energies," "Energy Summit," and "The Summit Energy" are all likely blocked too.
  • ✓
    Call the SOS for a free preliminary check on borderline names. (512) 463-5555. The SOS representatives will run your name through the database over the phone for free. This is especially useful when your name is similar to but not identical to an existing entity.
  • ✓
    Have a backup name ready. Pick two or three names before you file. If your first choice is rejected, you'll want to move immediately rather than restarting the research process. This is even more important if you're filing right before a deadline.
  • ✓
    Use a formation service if naming confusion is a concern. Services like Northwest Registered Agent run name checks before filing and have experience identifying potential conflicts. Their formation process includes catching naming issues before they reach the SOS. See best LLC formation services →

If you're not ready to file immediately, reserve the name for $40 for 120 days via Form 501.

Frequently Asked Questions

How do I search for an LLC name in Texas?

To do a Texas LLC name search, use the free Texas Comptroller Taxable Entity Search (no account required) at comptroller.texas.gov, or the paid SOSDirect search ($1 per search) at direct.sos.state.tx.us. The Comptroller search is the fastest free option. SOSDirect is more comprehensive — it includes reserved names and inactive entities that the Comptroller tool may miss.

Is there a free Texas LLC name search?

Yes. The free LLC name search in Texas is available through the Texas Comptroller's Taxable Entity Search at comptroller.texas.gov — no account needed, no fee. You can also email corpinfo@sos.texas.gov or call (512) 463-5555 for a free preliminary check from the SOS Corporations Section. Our name availability checker tool is also free.

What is the Texas SOS LLC name search on SOSDirect?

The Texas SOS LLC name availability search on SOSDirect (direct.sos.state.tx.us) is the official paid search system operated by the Texas Secretary of State. It charges $1 per search and requires a free account. It's the most comprehensive Texas secretary of state LLC name search available — covering active entities, inactive entities, reserved names, assumed names, and foreign entities registered in Texas.

How much does it cost to reserve an LLC name in Texas?

Reserving an LLC name in Texas costs $40 per name and secures the name for 120 days via Form 501, filed through SOSDirect or by mail. The reservation is "generic" — it can be used to form any entity type (LLC, corporation, etc.). Renewal is possible within 30 days of expiration using Form 507.

What naming rules apply to Texas LLCs?

Texas LLC names must: (1) include an approved designator (LLC, L.L.C., Limited Liability Company, LC, etc.), (2) be distinguishable from all existing Texas entities in SOS records, (3) not imply government affiliation, banking, or insurance without authorization, and (4) not contain prohibited words like "Bail Bond." Rules are governed by Texas BOC §5.053–5.056 and Texas Administrative Code, Title 1, Part 4, Chapter 79.

Does adding "LLC" vs "Inc." make a Texas business name distinguishable?

No. Under Texas naming rules, different designators (LLC vs Inc. vs Corp) do not create distinguishability. "Austin Bakes LLC" and "Austin Bakes Inc." are considered the same name. You need a meaningfully different name — not just a different ending. This is one of the most common mistakes in Texas LLC name searches.

Can I search Texas LLC names by owner name?

Yes. The Texas LLC search by owner name feature is available through SOSDirect. You can search entities by member, officer, or organizer name. This is useful for researching competitor business structures or verifying information about a potential business partner's existing entities in Texas.

What happens if my Texas LLC name is rejected?

If the Texas SOS rejects your LLC name, you'll receive a written notice explaining the reason. The $300 Certificate of Formation filing fee is non-refundable. You must correct the name issue and re-file with a new $300 payment. This is why completing a thorough Texas LLC name availability search before filing is essential — it's the only way to avoid paying twice.

Does the Texas Comptroller LLC name search cover reserved names?

No. The Texas Comptroller LLC name search does not show names that have been reserved by other filers. Only the Texas SOS LLC name search on SOSDirect reveals reserved names. This is a critical gap — someone could have reserved your desired name for 120 days without you knowing, unless you check SOSDirect.
