Florida LLC Naming Rules (§605.0112)
Florida's naming requirements come from Florida Statute §605.0112, the Revised Limited Liability Company Act. Your name must meet all four requirements below before the Division of Corporations will accept your Articles of Organization filing.
Rule 1 — Required Designator
Every Florida LLC name must end with one of these approved designators to signal it is a limited liability company:
- LLC — most common choice, simplest
- L.L.C. — with periods, equally valid
- Limited Liability Company — written out in full
- "Ltd." or "Co." alone — rejected outright by Sunbiz
Most people use "LLC." It's clean, professional, and what clients, banks, and vendors expect. Save "Limited Liability Company" for formal legal documents — on business cards, signage, and email signatures, "LLC" is standard.
Rule 2 — Distinguishability
Your name must be distinguishable on the records of the Florida Division of Corporations from every other entity — including active, inactive, reserved, and dissolved entities in Sunbiz. "Distinguishable" means meaningfully different in wording, not just different spelling or punctuation.
For example, if "Sunrise Consulting LLC" is already in Sunbiz, you can't use "Sunrise Consulting Company LLC" or "Sunrise Consulting Group LLC" without risking rejection. The search system ignores designators (LLC/L.L.C.) and treats uppercase and lowercase as identical, so your search should do the same.
Rule 3 — No Government or Entity Confusion
Your LLC name can't imply that it's a government agency, a corporation, a bank, or any other entity type it isn't. Words like "Department," "Bureau," "Federal," "State," or "United States" are off the table. The name also can't suggest it's a corporation (e.g., can't include "Inc." or "Corp." as a designator).
Rule 4 — Restricted Professional Words
Words associated with licensed professions require prior authorization or proof of licensure. You can't use these words in your Florida LLC name unless you meet the professional requirements:
| Restricted Word | Who Can Use It | Required Proof |
|---|---|---|
| Engineer / Engineering | Licensed engineers only | FL Board of Professional Engineers |
| Architect / Architecture | Licensed architects only | FL Board of Architecture |
| Attorney / Law / Legal | Licensed attorneys only | Florida Bar authorization |
| Doctor / Medical / Dental | Licensed practitioners only | FL Dept. of Health |
| Realtor / Realty | Licensed real estate professionals | FL Real Estate Commission |
| Bank / Banker / Banking | Regulated financial institutions | FL Office of Financial Regulation |
| Insurance | Licensed insurers | FL Dept. of Financial Services |
Important for PLLCsIf you are a licensed professional (CPA, attorney, dentist, architect), you may need to form a Professional Limited Liability Company (PLLC) rather than a standard LLC. The naming rules and designator requirements differ. Check with your professional licensing board before filing.
How to Search Florida LLC Name Availability
The Florida Division of Corporations provides a free business entity search tool through Sunbiz. There is no limit on how many times you can search, and no account is required.
How to Run the Search (Step by Step)
- Go to search.sunbiz.org and select "Search by entity name" — this is the correct option for checking LLC name availability.
- Type only the core words of your proposed name — leave out "LLC," "L.L.C.," or "Limited Liability Company." The system ignores designators, so omitting them gives more accurate results.
- Leave out punctuation marks (commas, periods, apostrophes). The system treats them as the same regardless of case or punctuation.
- Hit Search and review all results. Look for names that are identical or confusingly similar to what you want — not just exact matches.
- If your name returns no conflicting results, it's likely available. If you see a close match, choose a different, more distinctive name.
- Run your search multiple times with variations — try the main words separately and in different orders to spot potential conflicts.
Ahmad Adil's TakeDon't stop at the Sunbiz search. Also check if the matching .com domain is available — your business name, domain, and email should all line up. A business called "Oak Street Consulting LLC" that can't get oakstreetconsulting.com will always feel mismatched. Check domain availability before committing to your name.
Tips for Choosing a Strong Florida LLC Name
A good LLC name does three things: it satisfies Sunbiz's legal requirements, it's easy for customers to remember, and it sets you apart from competitors. Here's what actually works in practice:
- Use your real name: "Smith Consulting LLC" or "Johnson Media LLC" — distinctive, professional, and almost never conflicts.
- Be specific about what you do: "Orlando Property Management LLC" is better than "Florida Services LLC" — it's more searchable and more trustworthy.
- Keep it short: 2–4 words before the designator is the sweet spot. Long names are harder to say, type, and remember.
- Check the domain before you decide: If yourname.com is gone, revisit before committing. A mismatched domain hurts credibility.
- Avoid generic adjectives: "Premier," "Elite," "Pro," "Advanced" — these are overused and harder to trademark or distinguish in Sunbiz.
- Don't limit your future growth: "Miami Plumbing LLC" ties you to one city; "Coastal Home Services LLC" works statewide.
Using a DBA (Fictitious Name) in Florida
Once your LLC is formed, you can operate under a different name by registering a DBA (Doing Business As), which Florida calls a Fictitious Name. This lets "Smith Holdings LLC" legally operate as "Tampa Bay Cleaning Co." without forming a new LLC.
Florida fictitious name registration is done through Sunbiz for $50 and must be renewed every 5 years. It's published in a local newspaper as part of the process. A DBA is useful when you want to run multiple brands under one LLC, or when your LLC name is your personal name but your brand uses a trade name. Learn more in our LLC DBA guide.
Should You Reserve Your Florida LLC Name?
Florida allows you to reserve an LLC name for 120 days by filing a Name Reservation Application through Sunbiz and paying a $35 fee. The reservation holds the name against other filers while you prepare your Articles of Organization.
In most cases, you should skip the reservation. If your name is available on Sunbiz right now, file your Articles of Organization immediately — it's faster, it's cheaper (the $35 reservation fee is separate from and in addition to the $125 filing fee), and it eliminates the window of risk. Reservation only makes practical sense if you've confirmed your name but genuinely can't file for weeks — for instance, you're waiting on co-founders to sign documents.
After you're formed:Once Sunbiz approves your Articles of Organization, your LLC name is permanently registered in Florida. Dissolved LLC names are held for one year before becoming available to other filers, per the Florida Division of Corporations.
