Last Updated April 30, 2026 by the LLCForge Editorial Team. Verified against current state filing data and official Secretary of State sources.
Connecticut’s distinguishability standard means your LLC name has to be meaningfully different from every existing entity on the Secretary of the State’s records — different punctuation, articles, or entity designators don’t count. The search tool below queries the state’s live business database in real time, so you can confirm availability without bouncing through Connecticut’s online portal. Online Articles of Organization filings typically process within a week, but turnaround varies by season. Confirm your name close to when you actually intend to file.

Tips for Better Connecticut LLC Name Search Results
The search tool above queries Connecticut Secretary of the State business records directly, but a few habits will help you avoid surprise rejections after you file:
Search the core name without the designator first
Leave off “LLC,” “L.L.C.,” or “Limited Liability Company” on your first pass. Connecticut ignores entity designators when judging distinguishability, so “Riverbend Coffee LLC” and “Riverbend Coffee, Inc.” count as the same name for conflict purposes. Searching the core word gives you the broadest view of potential conflicts.
Test variations and singular/plural forms
Run a second and third search swapping in plurals, possessives, abbreviations, and common descriptive words like “Group,” “Services,” or “Holdings.” Connecticut, like most states, treats minor differences (punctuation, articles like “the,” spacing) as not distinguishable. A name that returns no exact match might still conflict with a near-match the state considers identical.
Check active and recently dissolved entities
The results show active and recently dissolved entities. A name belonging to an admin-dissolved or recently withdrawn entity often remains protected for a window of months or years before returning to the available pool. Treat any close match as a potential block until you confirm otherwise.
Confirm against the naming rules below, not just the search
The search tool tells you what’s in the database. It doesn’t tell you whether your name violates Connecticut’s restricted-words list (banks, insurance, professional services, etc.) or conflicts with a federal trademark. Read the naming rules section below before committing to a name, and run a quick USPTO trademark check too.
Lock in fast or reserve it
Connecticut doesn’t hold a name for you just because you searched it. If you’re filing your Articles of Organization within the next few days, skip the reservation. If you need time to line up a registered agent or finalize an operating agreement, file a name reservation through the Connecticut Secretary of State to hold the name during the reservation window detailed in the data card above.
Connecticut LLC Naming Rules
Designator requirement
Your name must end with one of: “Limited Liability Company,” “L.L.C.,” “LLC,” “Limited Liability Co.,” “Ltd. Liability Company,” or “Ltd. Liability Co.” Most filers use “LLC” because it’s clean and saves space on contracts and business cards.
Distinguishability standard
Connecticut requires your name to be “distinguishable upon the records” from every other active or reserved name. The Secretary of the State ignores these when comparing:
- Entity designators (LLC vs. Inc. vs. Corp.)
- The articles “a,” “an,” “the”
- Punctuation, capitalization, and spacing
- Singular vs. plural forms in some cases
Adding a single descriptive word, a geographic identifier, or a different industry term usually does the job. “Hartford Builders LLC” and “Hartford Custom Builders LLC” are different. “Builders LLC” and “Builders Inc.” are not.
Prohibited words
You can’t use language that implies your LLC is a government agency. Words like “FBI,” “Treasury,” “State Department,” or anything suggesting federal or state affiliation are off-limits.
Restricted words requiring approval
Certain regulated industry terms need additional licensing or approval before they can appear in your name:
- Bank, banker, banking, trust: Approval from the Connecticut Department of Banking
- Insurance, insurer, assurance: Department of Insurance review
- Engineer, engineering, surveyor, architect: Licensing board sign-off
- Attorney, lawyer, law office: Restricted to licensed practitioners
- CPA, accountant: State Board of Accountancy approval
- Doctor, medical, pharmacy: Department of Public Health
What If Your Connecticut LLC Name Is Already Taken?
Variation strategies that work
Add a meaningful descriptor before or after the conflicting word. “Northeast” plus the original name. A specific service (“Consulting,” “Logistics,” “Studio”) added to the back. A founder’s initials. Geographic markers like “New Haven” or “Fairfield County” are particularly effective in Connecticut because they signal location and create real distinguishability.
What doesn’t work: changing “and” to “&,” swapping LLC for L.L.C., or adding “The” at the front. The state will reject those as functionally identical.
Reserve the name while you finalize paperwork
If your name clears but you’re not ready to file your Certificate of Organization, you can reserve it for 120 days by filing an Application for Reservation of Name with the Secretary of the State. The fee is $60. This is worth doing if you’re still drafting your operating agreement, lining up funding, or coordinating with co-owners on a launch date.
DBA / trade name option
Connecticut LLCs can operate under a trade name (also called a DBA or fictitious name) that’s different from the legal LLC name. Trade names are filed at the town clerk’s office in the town where you do business, not at the state level. This is useful if you formed “Smith Holdings LLC” but want the storefront to say “Riverside Bakery.” A trade name doesn’t replace your legal name on contracts, tax filings, or court documents.
Trademark considerations
State name approval is a clerical check, not a legal clearance. The Secretary of the State doesn’t compare your name against federal trademarks, common law trademarks, or names registered in other states. If you plan to operate beyond Connecticut or sell branded products, search the USPTO database and consider filing your own federal trademark once you’re established.
After You Confirm Your Connecticut LLC Name
Once your name clears, the next move is filing your Certificate of Organization with the Connecticut Secretary of the State. The state filing fee is $120, and standard processing is typically 3 to 5 business days for online filings. You’ll also need a Connecticut registered agent with a physical address in the state.
Walk through the full filing sequence in our Connecticut LLC formation guide, review the broader requirements in the Connecticut LLC state guide, compare options in the Connecticut registered agent guide, and draft your internal rules using our Connecticut operating agreement guide.

Frequently Asked Questions
How do I know if a Connecticut LLC name is actually available?
Run it through the CONCORD business inquiry, then test variations with different spellings, punctuation, and pluralizations. If nothing active comes back as a close match, you’re likely clear. The only way to get a binding answer is to file the Certificate of Organization or a Name Reservation and let the Secretary of the State review it.
How long does a Connecticut name reservation last?
120 days from the date of filing. The fee is $60. If you need more time, you can reapply, but you can’t simply renew the same reservation indefinitely.
Can my LLC’s legal name be different from my brand or trade name?
Yes. Your legal LLC name goes on state filings, contracts, and tax documents. Your trade name (DBA) is what customers see on signage, websites, and marketing. File trade names at the town clerk’s office where you do business, not with the state.
Does my LLC name have to match my domain name?
No, but it helps. A matching .com builds trust and makes you easier to find. If your exact name isn’t available as a domain, consider adding “co,” “hq,” or your city. Don’t pick a Connecticut LLC name based purely on domain availability if it weakens your brand.
What makes two Connecticut business names “distinguishable”?
Different distinctive words. Adding “the” or changing punctuation isn’t enough. Adding a real word (“North,” “Premier,” “Coastal,” “Digital”) or a clearly different service descriptor is. The Secretary of the State applies this test based on what a reasonable person reading the records would see as a separate business.
Can I use the same name as a dissolved or forfeited Connecticut LLC?
Sometimes. If the prior entity has been dissolved or forfeited for long enough, the name may be available again. The CONCORD search will show the status. Before you commit, contact the Secretary of the State’s business services division to confirm the name is releasable, since some statuses still block reuse.
