Connecticut LLC Name Search — Step 1 of 8
Connecticut's naming rules follow the standard playbook — a required designator, and distinguishability from every other entity on file. Here's how to check availability and lock in a compliant name.
Your Connecticut LLC name must include an approved designator — "LLC," "L.L.C.," or "Limited Liability Company" (or "Ltd. Liability Co.") — and be distinguishable from every other entity on file with the Secretary of the State. Search availability for free through the Business Records Search tool on Business.CT.gov before you file.

Connecticut's Naming Rules
Connecticut's LLC Act (Uniform Limited Liability Company Act) keeps naming requirements fairly conventional:
- Must include a designator — "Limited Liability Company," "LLC," "L.L.C.," or "Ltd. Liability Co."
- Must be distinguishable from every other business entity on file with the Connecticut Secretary of the State — active businesses, reserved names, and registered names alike.
- Can't falsely imply a government affiliation or a different entity type than it actually is.
- Restricted words like "Bank," "Insurance," or "University" may need extra approval or licensing before use.

Reserving Your Name (Optional)
Connecticut checks your name when you file your Certificate of Organization, so a separate reservation is entirely optional — most people skip it and go straight to filing. But if you're not ready to file yet and want to lock in a name:
- File an Application for Reservation of Name (Form BUS-002) online or by mail for $60.
- Holds your name for 120 days, giving you time to finish other preparations before filing.
- Also check the USPTO trademark database separately — state name availability and federal trademark protection are two different systems.
Planning to operate under a different name?If you want to market your business under a name other than your LLC's legal name, you'll file an Assumed Name Certificate (DBA). Note that in Connecticut, this filing is handled at the town/county clerk level, not the Secretary of the State — fees and exact process vary by municipality, so check with your local town clerk.
