LLC Name Checker: Check Your LLC Name Availability
Understand what states require of an LLC name, then check the domain and handle availability for your name across 45+ platforms in one search.
Naming an LLC has two sides. One is legal: your state has specific rules about what an LLC name must contain and how different it must be from existing companies. The other is practical: the matching domain and social handles need to be free so your brand is consistent. NameCheq handles the online side instantly; below are the general legal rules most states share, so you choose a name that works on both fronts.
1. The LLC designator requirement
Almost every state requires an LLC’s legal name to include a designator that signals its entity type, typically “Limited Liability Company” or an abbreviation such as “LLC” or “L.L.C.”, and some states also allow “Limited Liability Co.” The exact accepted forms vary by state, so confirm with your Secretary of State. Your everyday brand name does not have to display the designator on your logo or website, but your registered legal name must include it.
2. Distinguishability from existing entities
Your LLC name must be “distinguishable on the records” of the state from names already registered there. Importantly, the designator itself usually does not make a name distinguishable, “Acme LLC” and “Acme Inc.” are typically treated as the same, and many states ignore differences that are only capitalization, punctuation, spacing, or added/removed minor words. You check distinguishability on your state’s Secretary of State business-name search before filing.
3. Restricted and prohibited words
Most states restrict words that could mislead the public. Names cannot imply a government agency (for example “FBI” or “Treasury”), and they generally cannot include designators for other entity types such as “Corp” or “Inc” in an LLC name. Regulated terms, such as “Bank,” “Insurance,” “Trust,” or “University,” often require special approval or licensing. The exact list varies by state, so check your Secretary of State’s naming guidelines.
4. Online availability (where NameCheq helps)
Once your LLC name clears the state rules, you still need the brand to exist online. NameCheq checks your name across 45+ platforms at once, domains, social handles, app stores, and developer registries, so the public-facing brand around your LLC is consistent. NameCheq does not check or reserve names with any state LLC registry; that step stays with your Secretary of State.
How to check LLC name availability
Work in order: (1) draft names that include a valid LLC designator; (2) search your state’s Secretary of State LLC database for distinguishability and restricted words; (3) reserve the name with the state if you are not ready to file; (4) run a USPTO trademark search; (5) use NameCheq to confirm the domain and handles are free, then claim them. Clearing the state rules first avoids committing to a name the state will reject.
Frequently asked questions
Does NameCheq check LLC name availability with my state?
No. Whether an LLC name is available to register is determined by your state’s Secretary of State LLC registry. NameCheq checks online availability, domains and 45+ platform handles, not government records.
Does my LLC name have to include “LLC”?
In almost all states, yes. The legal name must include a designator like “LLC,” “L.L.C.,” or “Limited Liability Company.” Accepted forms vary, so confirm with your state.
What makes an LLC name “distinguishable”?
It must differ from existing registered names by more than the entity designator, capitalization, punctuation, or spacing. The precise standard varies by state and is checked on the Secretary of State search.
Can I use words like “Bank” or “Insurance” in my LLC name?
Often only with special approval or a license. Words implying a government agency, or designators for other entity types like “Inc” or “Corp,” are typically prohibited in an LLC name.
Can I reserve an LLC name before filing?
Most states let you reserve a name for a set period through the Secretary of State while you prepare your formation documents.
Is this legal advice?
No. This is general information about common LLC naming rules. Requirements vary by state, confirm with your Secretary of State or a business attorney before filing.
