Florida Corporation Name Search — Checking Availability and Naming Rules

The Florida Division of Corporations maintains a public database of every registered entity in the state, searchable through Sunbiz. Before you settle on a name, search it.

Running the search

Go to the Sunbiz name search tool and search your proposed corporate name. Then search variations — drop or add words, change the order, try singular and plural, and test similar-sounding alternatives. The database covers all entity types: corporations, LLCs, limited partnerships, and others. Your corporation's name has to be distinguishable from all of them, not just other corporations.

Read the results critically

Don't just look for an exact match. Look for names that are close enough that the Division might consider them not distinguishable. If you find something similar, assume it could be a problem and either adjust your name or be prepared for the possibility of rejection. A little care here avoids a rejected filing and a delayed formation.

The search doesn't reserve anything

Searching only tells you what exists right now. It doesn't hold the name for you, and it doesn't guarantee the Division will approve it — the examiner makes the final call when you file. Two people can search the same available name; whoever files first and gets approved gets it.

Florida requires a corporation's name to be "distinguishable" from every other name on file. That's a legal standard, and it's stricter than most people expect.

Differences that usually don't count

The Division generally does not treat these as making a name distinguishable:

• Punctuation, spacing, or capitalization differences
• The words "the," "and," "a," or an ampersand
• Singular versus plural versus possessive forms of the same word
• Adding or removing the corporate designator itself (Inc., Corp., etc.)

So "Bright Harbor Inc." and "Bright Harbor Corporation" would likely be considered the same name, as would "Bright Harbor" and "The Bright Harbors." If your only difference from an existing entity is one of these, expect a conflict.

Differences that usually do count

Adding a genuinely different, meaningful word — not just filler — typically makes a name distinguishable. "Bright Harbor Marine Corp." is meaningfully different from "Bright Harbor Inc." The safest approach is a name with enough distinct substance that no reasonable person would confuse it with an existing entity.

Beyond distinguishability, Florida has specific rules about what a corporation's name must and must not include.

Required corporate designator

A Florida corporation's name must include a word or abbreviation that identifies it as a corporation:

• "Incorporated" or "Inc."
• "Corporation" or "Corp."
• "Company" or "Co." (used in a way that doesn't mislead about the entity type)

This designator tells the public they're dealing with a corporation. Choose one that fits the name and use it consistently on your Articles and afterward.

Restricted and prohibited words

• Government implications: The name can't falsely suggest the corporation is a government agency or affiliated with one.
• Regulated industries: Words like "bank," "banking," "trust," and "insurance" generally require approval from the relevant Florida regulatory agency before you can use them, because they imply a regulated activity.
• Professional designations: If you're forming a professional corporation (for licensed professionals like doctors or attorneys), additional naming rules and designators may apply.

When in doubt about a restricted word, check with the Division or the relevant regulator before you build a brand around a name you might not be allowed to use.

It happens — you find your ideal name already belongs to another Florida entity. You have several options.

Adjust the name

The simplest fix is to modify your name so it's genuinely distinguishable — add a meaningful word, rework the phrasing, or choose a different core term. Search the new version before committing to make sure the adjustment actually clears the conflict.

Use a fictitious name (DBA)

If your legal corporate name is taken but you want to operate under a particular brand, you can incorporate under an available legal name and register a fictitious name (a "DBA") for the brand you want to market under. Florida fictitious name registration runs through Sunbiz, lasts five years, and requires publishing a notice in a newspaper in your principal county. The corporation's legal name and its fictitious name can differ.

Consider trademark separately

Availability on Sunbiz is not the same as trademark clearance. A name can be available to register as a Florida entity while still infringing someone's federal or common-law trademark. If your name is important to your brand, a trademark search — and potentially a federal registration with the USPTO — is a separate step worth taking. State entity registration and trademark protection are different systems.

Once you've confirmed a name that's available and compliant, the name goes into your Articles of Incorporation exactly as you want it recorded.

Lock it by filing

Florida doesn't offer a general name reservation for corporations the way some states do, so the reliable way to secure a name is to file the Articles of Incorporation. Until the corporation is formed, the name isn't yours — someone else could file first. If you've done the search and you're confident in the name, filing promptly is how you claim it.

Get the exact name right

The name on your Articles becomes your corporation's legal name of record. Double-check spelling, the designator (Inc. vs. Corp.), and capitalization before you file — correcting it afterward means an amendment. It's a small thing that's worth a careful second look.

How Mainstay Filing helps

When Mainstay Filing prepares your Articles of Incorporation, we help confirm your chosen name is available and formatted to Florida's rules before submitting, reducing the chance of a rejection over a name conflict or a missing designator. If your first choice is taken, we'll flag it so you can adjust before filing rather than after.
