Texas LLC Name Search and Naming Rules

Your LLC's name has to be available before Texas will register it — meaning it can't be the same as, or too close to, a name already on file with the Secretary of State. Checking first is not optional busywork; a conflict gets your Certificate of Formation rejected and sets your formation back.

The official search: SOSDirect

The authoritative name search runs through SOSDirect, the Secretary of State's online system. It reflects the actual SOS records the state uses to judge availability, and it charges a small per-search fee. Because SOSDirect is the record the state relies on, this is the search that counts when you're serious about a name.

A free preliminary check

For a rough, free read before you pay for a SOSDirect search, the Comptroller's taxable-entity search lets you look up existing Texas entities. It's useful for eliminating obvious conflicts early, but it's not the final word — the SOS database governs availability, so confirm there before filing.

Search smart, not just exact

Don't only search your exact desired name. Search close variations: different word order, singular versus plural, added or dropped filler words, and similar-sounding alternatives. Texas judges names by whether they're distinguishable, not identical, so a name that merely resembles an existing one can still be rejected. Searching broadly saves you from a surprise rejection.

Texas won't register a name that isn't distinguishable from names already on file. This is a legal standard, and it's stricter than most people expect.

Differences that usually DON'T make a name distinguishable

• Punctuation and spacing changes alone
• Adding or dropping "the," "a," "an," "and," or "&"
• The difference between singular and plural (e.g., "Solution" vs. "Solutions")
• The entity designator itself — you can't distinguish a name just by using "LLC" where another used "Inc."
• Minor spelling variants that read or sound the same

Differences that generally DO help

• Genuinely different distinctive wording
• A meaningfully different core term, not just a filler word
• Additional distinctive words that change the overall commercial impression

The core name — the distinctive part — is what matters. If the distinctive portion of your name is effectively the same as an existing entity's, adding filler or swapping the designator won't rescue it. When in doubt, lean toward a name with a clearly unique distinctive element.

Beyond availability, your name has to follow Texas's content rules for LLC names.

Required designator

Your LLC's name must include one of the accepted designators:

• "Limited Liability Company" or "Limited Company"
• An abbreviation: "LLC," "L.L.C.," "LC," or "L.C."
• "Limited" may be abbreviated as "Ltd." and "Company" as "Co." within those forms

Restricted and prohibited words

• Government implication. The name can't falsely suggest it's a government agency or affiliated with one.
• Regulated terms. Words like "bank," "banc," "trust," "insurance," and similar financial terms typically require approval from the relevant Texas regulator before the SOS will accept them.
• Professional terms. Certain professional-practice words may require you to be a professional entity or have appropriate licensure.
• Misleading purpose. The name can't imply a purpose the LLC isn't lawfully authorized to pursue.

Practical naming advice

Pick a name whose distinctive element is genuinely yours, confirm it's available on SOSDirect, and — separately from state availability — consider checking for a matching domain and any federal trademark conflicts. State name availability and trademark rights are different things: clearing the SOS doesn't guarantee you have trademark rights, and a registered trademark can constrain your use even if Texas registered your entity name.

Found an available name but not ready to file your Certificate of Formation? Texas lets you hold it.

Name reservation

You can reserve an available LLC name for 120 days by filing a name reservation application through SOSDirect for a small fee. The reservation locks the name against others registering it while you handle other pieces — lining up your registered agent, drafting your operating agreement, or finalizing partners. It does not create the LLC; it only protects the name for the reservation period. You can typically renew a reservation if you need more time.

When reservation is worth it

• You've settled on a name but need weeks to get organized before filing
• You're worried a competitor or someone with a similar idea might grab it
• You're coordinating a multi-entity setup and want names locked in advance

Most owners who are ready to file simply file — the Certificate of Formation itself secures the name. Reservation is for the in-between situation where you want certainty without filing yet.

Your LLC's legal name is the one on the Certificate of Formation. If you want to do business under a different name, that's a separate registration.

Assumed name certificate

To operate under a name other than your LLC's legal name, you file an assumed name certificate with the Secretary of State on Form 503. For example, "Lone Star Ventures LLC" trading publicly as "Hill Country Coffee Roasters" would register that trade name. An entity's Texas assumed-name certificate can run up to ten years before renewal.

Availability applies here too

An assumed name doesn't get the same exclusivity as your registered legal name, but you still shouldn't pick one that conflicts with existing marks or entities. Search before you register, and consider the same trademark check you'd do for a legal name.

Legal name vs. brand

Many owners deliberately choose a simple, conflict-free legal name for the entity and then operate under one or more assumed names for branding. That's perfectly normal — the legal name is your compliance identity with the state; the assumed name is how customers know you. Just keep both registered and current.
