Commercial insurance leads: how agents build their own prospect lists by trade

Commercial insurance agents can build their own lead lists by listing every business in a trade they write well (contractors, restaurants, trucking, auto repair) inside the counties they're licensed in, then contacting each business ahead of its renewal. Google Maps gives you every such business with a phone number and website, and public data adds more for some trades: federal records show which trucking companies have operating authority and insurance on file. A self-built list isn't shared with other agents, but nobody on it asked for a quote, so the outreach has to earn the conversation.

Shared leads, exclusive leads or your own list?#

Each source trades cost and intent against competition. Most agencies use more than one.

The self-built list wins on cost and exclusivity, and it lets you go deep in one trade, which is how most commercial books grow.

Which trades make the best commercial insurance prospects?#

Pick trades with several coverages per policyholder, real exposure, and a clear yearly renewal. The table lists coverages commonly discussed with each trade; what a given business needs depends on its operations and its state.

Trucking is a good example of a trade where the rules set a floor. Under 49 CFR 387.9, for-hire interstate carriers of non-hazardous property in vehicles of 10,001 pounds or more must carry at least $750,000 of public liability coverage. Certain oil and hazardous materials require $1,000,000, and some bulk hazardous materials $5,000,000. Every one of those carriers must maintain that coverage, and carriers with operating authority file proof of it with FMCSA, which makes them a defined, findable market.

How do I build a list of businesses by trade and county?#

Search each trade in each county you're licensed in, export, then clean.

1. List your trades and the Google Maps categories for each. Contractors alone span "general contractor", "roofing contractor", "electrician", "plumber", "HVAC contractor", "concrete contractor" and more. Our keyword packs group these.
2. Search county by county, in pieces. A single Maps search stops at about 120 results, so split large counties by city or ZIP code (why).
3. Export business, category, phone, website, address, rating and reviews.
4. Remove what you can't write: franchises with corporate programs, businesses outside your licensed states, trades your carriers won't take.
5. Rank the rest. Reviews hint at size and activity. A roofer with 300 reviews runs more crews than one with 8.
6. Add trade data where it exists. For trucking, match on USDOT number using FMCSA's public data (below). For bars, your state's liquor license list adds license type and date.

New businesses are worth a separate feed: a company that just opened needs its first policies. See new business license lists and finding new businesses in your area.

How do I find trucking companies and their insurance dates?#

Use FMCSA's public data. FMCSA has published insurance filings for carriers with operating authority as open data on data.transportation.gov, including the insurer, the liability limits, and the effective and cancellation dates. The dataset of active and pending policies ("ActPendInsur") was last refreshed in May 2026 and is marked as no longer updated, so check FMCSA for the current source before you rely on it.

Effective dates from a filing are a strong hint at the renewal month. Treat them as a hint, not a fact: policies can be rewritten mid-term, and a carrier may change insurers at any time. Confirm on the call.

When should I contact a business about renewal?#

Contact each business early enough to quote before it renews. Most businesses won't change agents mid-term, so the renewal window is when you win.

Our rule of thumb:

• First contact, any time: introduce yourself and ask one question, "When does your policy renew?"
• About 90 days before renewal: ask for the current declarations pages and loss runs, so you have time to shop markets. This is a working habit, not a regulation.
• 30 days before: present the quote.
• After renewal: if you lost, set a reminder for next year. A business that said "not this year" is a warm lead next year.

Put the renewal month in your CRM the moment you learn it. A self-built list becomes valuable when it turns into a calendar of renewals.

What should my outreach say?#

Be specific about the trade and ask one easy question. Business owners get many insurance calls, so show you know their work.

Email to a contractor#

Subject: {{business}}'s renewal

Hi there,

I write general liability and workers' comp for {{category}}
businesses in {{county}} County, so I know the questions carriers ask
about subs, payroll and job types.

When does {{business}}'s policy renew? If it's in the next few months,
I'm happy to run a comparison. All I'd need is your current dec pages.

[Name], [Agency] · Licensed in [states] · [Postal address]
Reply "no" and I won't write again.

Phone opener for a restaurant#

"Hi, is the owner or manager in? ... I'm [Name] with [Agency]. I work
with restaurants in [area] on their insurance, including liquor
liability. I'm not asking you to switch today. When's your renewal,
so I can send you a comparison a couple of months before?"

What compliance rules apply to insurance prospecting?#

Licensing comes first. Insurance producers are licensed by each state: a resident license in your home state, and a nonresident license in each other state where you sell, usually applied for through the National Insurance Producer Registry (NIPR). Lines of authority (property, casualty and others) must match what you sell. States also regulate insurance advertising and solicitation, and the rules differ, so check each state's department of insurance before you run a campaign there.

For the outreach itself:

• Email: CAN-SPAM covers commercial email to businesses. Honest sender and subject, your postal address, and an opt-out honored within 10 business days.
• Calls: under the FTC's Telemarketing Sales Rule, most business-to-business calls are exempt. Calls that sell to employees for their own use are not. The TCPA's rules on autodialed and prerecorded calls apply separately, and many small business owners list a cell phone.
• Google Maps terms restrict scraping Maps content and building lead lists from it. That's a contract matter, separate from insurance and email law.

See cold email laws, and get advice from your compliance team or a lawyer.

A worked example#

An illustration, with invented response rates: an agent licensed in two Texas counties lists roofers, general contractors and HVAC companies and gets 1,150 businesses. After removing franchises and trades their carriers won't write, 820 remain. Calling and emailing 820 businesses over a quarter, at an assumed 15% who share a renewal month, gives about 120 renewal dates spread across the year: roughly 10 quote opportunities a month, each timed. The point is the calendar: the same list keeps producing quotes for years if the renewal dates are recorded.

FAQ#

Where do commercial insurance agents get leads?#

From four places: referrals and existing clients, bought leads (shared or exclusive), associations and trade groups, and lists they build themselves. A self-built list of every business in a trade within a county costs the least per business and isn't shared with other agents, but it takes outreach work, since nobody on it asked for a quote.

What are the best industries for commercial insurance leads?#

Trades with several required or expected coverages and a clear renewal: contractors (general liability, workers' compensation, commercial auto, tools), restaurants and bars (property, liability, liquor liability where alcohol is served), trucking (auto liability with federal minimums), auto repair shops (garage and garagekeepers coverage), and medical and professional offices (professional liability).

When should I contact a business about its commercial insurance?#

Before its renewal, early enough to quote. Ask for the renewal month on the first call and set a reminder about 90 days before it. That's a rule of thumb for leaving time to gather information and shop markets, not a regulation.

Do I need a license in every state where I sell commercial insurance?#

Generally yes. Insurance producers are licensed by each state, with a resident license in the home state and nonresident licenses elsewhere, usually applied for through NIPR. Lines of authority (such as property and casualty) and advertising rules vary by state, so check each state's department of insurance.

Are shared insurance leads worth buying?#

They can be when you need volume quickly, because the business asked for a quote. The trade-off is that several agents usually get the same lead, so speed decides who wins. A self-built list gives you businesses no one else is calling that week, at a lower cost per business, but you have to start the conversation.
