How to Build a Florida B2B Prospect List by Industry and County

“All businesses in Florida” is not a target group. A prospect list becomes useful when it is narrow enough that the same message makes sense for every row. This guide walks through a method that relies on public sources and is candid about where those sources stop.

1. Describe the customer before you touch any data

Write down, in one sentence, who buys from you: “independent auto repair shops in Southwest Florida” or “community association management firms on the Gold Coast”. If you cannot write that sentence, no data source will fix it. Add what must be true for a record to be usable (a phone number, a website, an active registration), because every condition shrinks the list, and you should know that before you count.

2. Translate the industry into NAICS codes

Industry is usually expressed in North American Industry Classification System (NAICS) codes. Start broad (sector 23, Construction), then go as deep as your message requires (238160, Roofing Contractors). Two warnings:

• The Florida corporate registry does not record an industry at all. The content of formation documents and annual reports is set by statute (Fla. Stat. § 607.0202, Fla. Stat. § 607.1622), and an industry code is not part of it. Any NAICS code in a Florida list was added from another source or derived from a description.
• Codes are revised. The current edition is NAICS 2022; lists coded under an earlier edition need to be converted.

3. Choose counties, not “regions”

Florida has 67 counties, and the county is the cleanest geographic filter because every address belongs to exactly one. “South Florida” means different things to different people; “Miami-Dade, Broward and Palm Beach” does not. Typical groupings:

• Southeast: Miami-Dade, Broward, Palm Beach
• Tampa Bay: Hillsborough, Pinellas, Pasco, Manatee
• Orlando area: Orange, Osceola, Seminole, Lake
• Southwest: Lee, Collier, Charlotte, Sarasota
• Northeast: Duval, St. Johns, Clay, Nassau
• Panhandle: Escambia, Santa Rosa, Okaloosa, Walton, Bay, Leon

Keep in mind what the county on a list means: the county of the principal address on file. A contractor registered in one county may work in five others, and a company headquartered in Atlanta may run a large branch in Orlando without having a Florida principal address at all.

To see how many employer establishments a county has before you choose, use the official Census figures in our table Florida businesses by county; what they show is discussed in Florida business statistics by county.

4. Combine sources: none of them is complete

• Identity: the Division of Corporations (Sunbiz) for legal name, entity type, document number, status and addresses; the division also offers its corporate data as free downloads. See How to search Florida business records on Sunbiz.
• License: for regulated industries, the licensing agency. Contractors, real estate brokers, architects and lodging and food service establishments are licensed through the Department of Business and Professional Regulation; health care practitioners through the Department of Health. See Florida professional license lookups.
• “Doing business as” name: fictitious name registrations link a storefront name to the legal entity (Fla. Stat. § 865.09).
• Contact details: the company's own website. This is the one source where the business itself decided which phone number and email address to publish.

Matching these sources is the real work. Names differ (“Sunshine A/C LLC” versus “Sunshine Air Conditioning”), addresses change, and there is no shared identifier across agencies. Expect some records that cannot be matched, and do not force a match.

5. Decide the fields and keep the key

A workable minimum is legal name, entity type, document number, status, address, county, industry, phone number, email address and website. Always keep the document number. It is what lets you update the list later without creating duplicates, and it is how you prove where a record came from.

Leave empty fields empty. A guessed email address (info@ plus the domain) is not data, and sending to generated addresses is exactly what the CAN-SPAM Act treats as an aggravated violation when the message is otherwise unlawful (15 U.S.C. § 7704(b)(1)).

6. Clean before you count

• Status: remove inactive entities, or mark them, depending on your purpose. An entity that missed its annual report may still be operating; one that is active may not be.
• Duplicates: one business can appear as several entities (an operating company and a property-holding company at the same address). Decide which one you want.
• Agent addresses: if hundreds of records share one address, it is probably a registered agent's office, not a business district.
• Home addresses: a small business may be registered at the owner's home. Think twice before sending a sales representative there.

7. Check the rules for your channel before the first contact

The list does not decide how you may use it; the channel does.

• Direct mail to a business address is not subject to the consent and do-not-call rules for calls and texts described below; ordinary advertising law still applies.
• Email must comply with the CAN-SPAM Act, which “makes no exception for business-to-business email” (FTC compliance guide): accurate headers and subject line, a physical postal address and a working opt-out.
• Calls and texts fall under the federal TCPA rules and the Florida Telephone Solicitation Act (Fla. Stat. § 501.059), with consent requirements for automated dialing and separate national and Florida do-not-call lists.

The details, with links to each source, are in Cold outreach rules in Florida. Whatever the channel, keep a suppression list from day one and apply it to every new list.

Test small

Before you buy or build 10,000 records, work 100. Call or mail them, and count how many addresses were wrong, how many businesses had closed and how many were not what the code said. That error rate tells you more about a data source than any description of it – including ours.
