How to find shippers as a freight broker.

The advice you get as a new broker is "build relationships." Fine. With whom? The freight industry has a thousand articles about closing shippers and almost none about locating them, because the people writing those articles sell software to brokers and have never had to find a load themselves.

I spent fifteen years in trucking before I sat down at a broker's desk, most of it behind the wheel of a heavy haul truck. That changes how you look for freight. Drivers know where the loads are because they have been to the docks. This guide is that view, written out. It covers where shippers come from, how to tell which ones will work with you, and who to talk to once you have a name.

1. Pick a lane before you pick a list

The single biggest mistake I see is a new broker buying a list of 5,000 "shippers" and emailing all of them the same paragraph. Shippers get that paragraph forty times a week. The thing that makes them answer is the sense that you already know their freight, and you cannot know 5,000 companies' freight.

So narrow it first. Three questions:

• What equipment do you actually understand? Dry van, reefer, flatbed, step deck, heavy haul, tanker. If you have never moved a load that needed a permit, do not start with oversize. If you know reefer, the temperature conversations are your advantage.
• What region can you cover with carriers you trust? Your first shippers need flawless service, and flawless service comes from carriers you have used before. Start where your carrier relationships are.
• What commodity or industry do you have a story in? A former job, a family business, a customer you handled at a previous brokerage. Any specific knowledge beats none.

The intersection of those three is your lane. Everything below gets filtered through it. A broker who says "flatbed steel and building materials out of the Southeast" finds shippers faster than one who says "all freight, all 48," because the first one knows what to look for.

2. Twelve places shippers actually come from

Roughly in order of how much I use them. None of these require a paid database, though a couple get faster with one.

Load boards, read as intelligence

You are not on DAT or Truckstop to book freight from other brokers. You are there to see who is posting what out of which city. Search your lane, note the commodities and origin cities that repeat every week, and work backward to the plants that must be producing that freight. A weekly 45,000 lb flatbed load of "steel coil" out of one Alabama town narrows to two or three shippers in about ten minutes on a map.

Your carriers' drivers

This is the one most brokers never use. Every driver you dispatch picks up at docks you have never seen. Ask, casually and consistently: where did you load this morning, what do they ship, how busy was the yard, who else picks up there. Drivers will tell you which plants are running three shifts and which are half empty. That is market research no database sells.

Industrial directories

ThomasNet, state manufacturing association directories, and the NAICS-coded business lists your county economic development office publishes for free. Filter by the industries that ship in your equipment type: metal fabrication, lumber and building products, plastics, food processing, paper and packaging, machinery. The free lists are dated but they put pins on a map.

Import and export records

Ocean bills of lading are public. Services like ImportGenius and Panjiva index them; a few free tools show samples. A company importing forty containers a month of anything has inland drayage and truckload moves out of the port, and the BOL tells you the commodity, the port, and the consignee's address.

Construction and groundbreaking news

For flatbed, heavy haul, and building materials, nothing beats knowing about a project before the steel is ordered. Local business journals, state DOT project lists, and construction newsletters announce data centers, plants, distribution centers, and solar farms months ahead. Each one is a shipper for the contractor, the subs, and the equipment rental company.

Job postings

Search Indeed and LinkedIn for "shipping coordinator," "logistics coordinator," "traffic manager," and "transportation analyst" in your region. A company hiring for those roles has freight volume and probably pain. The posting usually names the facility, the products, and the software they use, and sometimes says "experience with freight brokers" outright.

Expansion and investment announcements

Governors love press releases: "$240 million expansion, 300 new jobs." Every one of those is a facility about to ship more than it did last year, often before its routing guide is built. Google News alerts for "expansion" plus your state plus "manufacturing" costs nothing.

Trade show exhibitor lists

Exhibitor lists are public and filterable by product category. A regional fabricated metal show gives you 200 companies that make heavy things, with booth contacts and addresses. You do not have to attend.

The industrial park, physically

Drive it. Look at what is in the yards: flatbeds with coil racks, reefer trailers, tankers, a sea of dry vans with a single carrier's name (that is a private fleet, skip it) or a mix of names (that is brokered freight, call them). Gate signs tell you receiving hours; trucks tell you equipment. This is a half-day that beats a week of database scrolling.

Your existing shippers' inbound

If you move outbound freight for a plant, ask about inbound. The raw material suppliers shipping to your customer are shippers too, and your customer's receiving manager can introduce you.

Carrier backhaul requests

When a carrier you trust says "I get empty in Columbus every Thursday," that is a lane with a truck already in it. Find the shippers in Columbus who need Thursday capacity and you are selling something real: a committed truck, not a promise.

Permit and regulatory filings

Oversize permit volumes, hazmat registrations, and EPA or state environmental permits are public in most states. They tell you who moves big things or regulated things, which is exactly the freight that is hard to cover and pays for service.

Paid contact databases, last

ZoomInfo, Apollo, and similar tools are useful for getting a name and an email once you have chosen the company. They are a poor way to choose the company. Use them to finish the list, not to start it.

3. How to tell if a shipper uses brokers

Not every company that ships is a prospect. Before you spend an hour researching one, check for the signs of variable, brokered freight:

• Mixed carrier names at the dock. Five different carriers in the yard means someone is sourcing trucks load by load. One name on every trailer means a private or dedicated fleet.
• Lumpy volume. Seasonal products, project work, promotional surges, harvests. A shipper whose volume swings can't run on a fixed fleet and leans on brokers for the peaks.
• Full truckload, not parcel or LTL. If the product ships in pallets via a national LTL carrier, you are fighting a different battle. Look for FTL commodities: coil, lumber, pipe, machinery, produce, paper, packaged food, beverages, building products.
• Mid-size company. Roughly 50 to 2,000 employees. Small enough that the shipping manager makes decisions, big enough to have weekly loads. Enterprise shippers run formal RFPs and onboarding that takes months; leave them for year three.
• Pain signals. A job posting for a logistics role, a Glassdoor review complaining about "constant carrier problems," a load that sat on the board for three days at a rising rate. Pain is the opening.

The shippers that fail these checks are not useless; they are just slow. A company with a 3PL contract renews it every one to three years, and the broker who has been politely in touch gets invited to the bid. But your first ninety days should go to the ones that tender loads every week and need trucks this week.

4. Who to contact, and who to skip

The most common reason outreach dies is that it reaches the wrong desk. Titles to look for, in order:

• Shipping manager, traffic manager, logistics coordinator at the facility. These people tender loads. They feel the pain when a truck no-shows. They can try a new broker on a single load without asking anyone.
• Plant manager or operations manager at a plant with no dedicated logistics role. Common below about 200 employees.
• Owner or general manager at family-owned manufacturers and distributors. They often handle freight personally and hate it.
• Purchasing or procurement when the company buys freight as a category. Slower, but they control the bid list.

Skip, at least at first: the VP of Supply Chain at headquarters (sets strategy, does not book trucks), anyone in sales or marketing, and the corporate switchboard. And never address a cold email to "Logistics Team." If you cannot find a name, you have not finished researching.

A practical trick: call the plant's main line and ask who handles outbound shipping. Receptionists at manufacturing plants will usually tell you. That one call converts a company name into a person, and a person is the only thing you can actually email.

5. What to do with the name

At this point you have a company that fits your lane, evidence it uses brokers, and a person who tenders the freight. Do not send the "we are a full-service 3PL with access to 50,000 carriers" email. Everyone sends that, and it says nothing about them.

Instead, write down the three things you learned: the commodity, the lane or the project, and the pain signal. Then lead with one of them. "Saw the expansion announcement for the Gadsden plant; flatbed capacity out of northeast Alabama has been tight on Mondays and I have two carriers based in Attalla who run that corridor weekly" is a first line that no template can produce, and it gets answered because it proves you did the work.

That process, research first and then write, is the whole method. If you want the structure for the email itself, read the cold email template guide. If you want to turn twelve sources into a working sheet, the prospect list guide covers the fields, the tiers, and the cadence. And if you would rather have the research done for you, that is exactly what Outbound was built to do: name the shipper, get the research and the sequence.

Shippers are not hiding. They are on load boards, in permit filings, in your drivers' mouths, and in the yard at the end of the industrial park. Pick a lane, go look, and write to the person who actually books the truck.
