Naming Your Business: Availability, DBAs, and Trademarks

By MercConsulting · Published 2026-07-18

Checking a Texas business name takes three separate searches: state entity records, USPTO trademarks, and domain/social handles. Here's how to run all three before you commit.

Checking whether a business name is available in Texas means running three separate checks, not one: the Texas Secretary of State's entity database (to register your LLC or corporation), the USPTO trademark database (to avoid a protected mark), and a domain and social-handle search (so the brand actually exists somewhere customers can find it). Passing the state's name check only tells you Texas will let you file paperwork under that name — it says nothing about whether a company three states away has built goodwill in it for years. Most naming problems trace back to a founder running the free state search, seeing a green light, and stopping there.

A business name is one of the few assets a young company builds real equity in — it's on every invoice, every review, every sign. Renaming six months in means reprinted signage, amended contracts, a new domain with zero search history, and customers who search for the old name and find nothing. This guide walks through all three checks, the Texas naming rules, when reserving a name makes sense, and where a do-it-yourself trademark search stops being enough.

"I checked that nobody else in Texas had the name, ordered signage, and printed a run of business cards before I found out a company in another state already owned the trademark. Nobody told me those were two different questions."

The Short Answer: Three Different Checks, Three Different Databases

Each check answers a different question, against a different database, and protects you from a different risk.

• Texas entity name availability — will the Secretary of State let me file with this name? Checks your proposed name against every entity already on file in Texas.
• Trademark availability — does someone already own rights to this name, or something confusingly similar, for a similar type of business, anywhere in the country? A federal question; Texas's approval has zero bearing on it.
• Domain and social handle availability — can customers actually find and reach my business online under this name? Not a legal check, but often the one that matters most day to day.

Run them in that order — each is progressively more expensive to fix once you're committed. A rejected state filing costs a few minutes. A trademark conflict discovered after you've built a brand can cost thousands in rebranding, or a cease-and-desist letter.

Check 1: Texas Entity Name Availability with the Secretary of State

The Texas Secretary of State maintains the master list of every corporation, LLC, and other registered entity in the state. Your proposed name has to be "distinguishable in the records of the secretary of state" from every name already on file — not identical, and not confusingly similar in a way that would mislead the public.

Check 2: A Basic Trademark Search Before You Fall in Love with a Name

State name approval and trademark rights run on completely different systems, and this is where most founders get tripped up. Texas will happily let you form an LLC called something that infringes a federally registered trademark, because the examiner isn't checking trademarks at all — only whether the name is distinguishable from other Texas filings.

Before you commit to a name — before the logo, the domain purchase, the signage order — run it through the USPTO's trademark search tool. Look for any registered or pending mark that's identical or similar, used in a similar category of goods or services (trademark protection is scoped by industry, so a similar name in an unrelated field is usually not a conflict). Also run a plain web and social-media search for the name in your industry; real-world conflicts often surface long before a formal trademark filing would catch them.

Check 3: Domains, Social Handles, and Real-World Confusion

The third check isn't a legal filing, but skipping it creates its own kind of damage. Search the domain you want (.com first, then whatever alternatives you'd actually accept), and check the handle across the social platforms your customers use — you don't need everything locked down before you file paperwork, but you want to know now whether you'll be fighting for a reasonable web presence later.

Also run a plain search of the name plus your city or industry. If a competitor, a defunct business with lingering reviews, or an unrelated company with a bigger footprint already owns the top results for that name, you're choosing to compete uphill on discoverability from day one — a real cost even with no legal issue at all.

Texas Naming Rules: Required Words, Restricted Words, and Distinctiveness

Beyond availability, Texas has substantive rules about what a business name can and can't contain:

• Entity designator required. An LLC's name must contain "Limited Liability Company" or an abbreviation like "LLC" or "L.L.C." Corporations need "Company," "Corporation," "Incorporated," "Limited," or an abbreviation such as "Co.," "Corp.," "Inc.," or "Ltd."
• Restricted words need extra approval. Words like "Bank," "Trust," "Insurance," "University," "Attorney," or "Engineer" typically require a supporting letter from the relevant regulatory body first, because they imply a licensed activity or chartered institution.
• No government affiliation implied. Names suggesting a federal or state agency get rejected outright.
• Distinguishability, not just uniqueness. The bar isn't "no one else has typed this exact string" — it's whether an examiner considers it likely to confuse the public with an existing name on record.

Deciding between your entity's legal name and a separate "doing business as" name for a specific brand or location is a related but distinct decision — see DBA or LLC in Texas: Which One Do You Actually Need? for how the two work together.

Reserving a Name vs Just Filing Your Formation

If you've confirmed a name is available but aren't ready to file your formation documents — waiting on a partner, financing, or a lease — Texas lets you reserve it so nobody claims it out from under you in the meantime.

Founders who've already picked a name and are ready to move usually skip this step and file the Certificate of Formation with the name built in — faster and cheaper than reserving first.

State Registration vs Trademark Rights: Why Approval Isn't Ownership

This is the single most common misunderstanding in the whole process: getting your entity approved with a given name does not mean you own that name, and it does not stop someone else, in Texas or anywhere else, from using a similar name or holding a trademark that predates your filing.

Practically, your state filing is the floor, not the ceiling, of your naming due diligence: it clears you to open a bank account and sign contracts under that name in Texas, but not to build a national brand or expand into other states without doing the trademark homework first. If growth beyond Texas is part of the plan, see our guide on foreign qualification when you're operating in multiple states.

When a Trademark Filing Is Worth Doing — With Professional Help

Not every business needs a federal trademark. A single-location service business with no plans to expand often gets by fine on state registration and consistent local use. A filing starts earning its cost when the name is core to how customers find you, when you're spending real marketing dollars on the brand, or when you plan to expand into new states, sell nationally online, or eventually license, franchise, or sell.

The filing itself is where a do-it-yourself approach gets risky — correctly classifying your goods and services, documenting actual use, and responding to examiner objections based on marks a basic search might have missed. A rejected application doesn't just cost the filing fee; it can weaken your position if you refile later. This is exactly the kind of work where professional guidance pays for itself — see our business formation services for how we scope that work.

Frequently Asked Questions

How do I search if a business name is available in Texas?

Use the Texas Comptroller's public entity search or the Secretary of State's SOSDirect system to check existing filings under that name or close variations. For a firmer answer, request a preliminary name availability determination from the Secretary of State for a small fee. This only checks state filing availability, not trademark or common-law rights.

Does registering an LLC protect my business name?

Only within Texas, and only against other entities trying to file an identical or non-distinguishable name with the Secretary of State. It does not give you trademark rights, and it won't protect you if someone else already held trademark rights before you filed. Real ownership comes from trademark law, not entity registration.

What is the difference between a business name and a trademark?

A business name is what the state recognizes for filing purposes; a trademark protects a brand identifier — name, logo, or slogan — as it distinguishes your goods or services from competitors', independent of any state filing. You can have a validly registered entity name that still infringes someone else's trademark.

Can two businesses have the same name in different states?

Often yes, at the state-filing level — Texas only checks its own entity database. But if either business holds trademark rights that extend into the other's market, or both start operating in the same market, a real conflict can still exist even though both state filings were approved independently.

How much does it cost to reserve a business name in Texas?

Texas charges a modest filing fee to reserve an entity name via Form 501, and the reservation typically holds for a limited period before it needs renewal or conversion into an actual formation filing. Fees can change, so confirm the current amount before filing rather than relying on a fixed number from any outside source, including this article.
