Do concrete contractors need a license number on their website?
Short answer: Concrete contractors in many states must show their license number on their website if they hold a contractor license or registration. Nevada, Oregon, Hawaii, Florida and Minnesota have written rules that put the number in advertising and cover websites or the internet. Even where no rule exists, put the number in your footer.
- Nevada's contractors board lists the website among the places a license number must appear.
- Oregon's OAR 812-003-0120 says website and other internet advertising must visually show the license number.
- Minnesota Statutes 326B.87 name websites and Internet ads among the advertising that must show a licensee's number.
- Florida's contractor FAQ says internet sites count as advertising for certified and registered contractors.
- Arizona requires the "ROC" prefix before the number; Pennsylvania requires registration numbers in ads, contracts and estimates.
- We did not confirm a rule in every state, so ask your board; this is not legal advice.
A license number is the number a state board, or a city or county, gave your business when it licensed or registered you. For concrete work it may be a specialty "concrete" license, a general or residential contractor license, or a home improvement registration. It depends on the state and sometimes on the dollar size of the job.
This page covers what we could confirm on official sources. Rules change, many are written for "advertising" in general, and concrete is licensed in very different ways from state to state. Check with your own board before you rely on this. This is not legal advice.
Is a website "advertising" for a concrete contractor?
Mostly, yes. If a page says you pour driveways and patios and how to hire you, a regulator can treat it as an ad. Several boards say so outright.
- Nevada's contractors board lists the website among the places a license number must appear, next to vehicles, business cards, letterhead, signage and directories (Nevada State Contractors Board: Advertising requirements).
- Oregon's rule says internet advertising, including website advertising, must visually show the license number (OAR 812-003-0120).
- Florida's contractor FAQ says internet sites count as advertising (Florida DBPR: Construction industry FAQs).
Other boards use the words "all advertisements" and do not name websites. In that case, assume the website is covered. It costs you one line of text.
What do the states say? A quick table
These are states where we found a written rule and opened the official source. "Concrete" is not always named. The rules apply to the license you hold, whatever trade it covers.
| State | What the source says | Source |
|---|---|---|
| Nevada | All forms of business advertising must show the license number. The board lists websites, vehicles, signs and online directories. | Nevada State Contractors Board |
| Oregon | A contractor may advertise only with a current license. Website and other internet ads must visually show the number. | OAR 812-003-0120 |
| Hawaii | Ads in all media, including the Internet, must show the licensee's name and license number. | Haw. Code R. 16-77-83 |
| Arizona | The number is preceded by "ROC". Internet ads can use a web address that links to a page showing the name and number. | A.R.S. 32-1124 |
| Florida | Certified and registered contractors show the number on ads, signs and some vehicles. Internet sites count as ads. | Florida DBPR |
| Minnesota | A licensee's number must appear in any advertising, and the statute names websites and Internet ads. | Minn. Stat. 326B.87 |
| Pennsylvania | Registered home improvement contractors put their registration number in ads, contracts, estimates and proposals. | Pennsylvania Attorney General: HIC FAQ |
That is not the full list. We checked many other states and either found no advertising rule or could not confirm one on an official page. "We did not find one" does not mean there is none, and a city or county may add its own. Ask your board.
Nevada: a clear website rule
Nevada has one of the plainest rules. The board's advertising page says all forms of business advertising must display your license number clearly, and it names the website. The page refers readers to NRS 624.720 and says advertising without a license is illegal (Nevada State Contractors Board). The page did not state a penalty on the section we read.
If you pour concrete out of Reno or Las Vegas, put the number in the site footer, on trucks and on every estimate. Our Nevada page has more.
Oregon: show it visually
Oregon's rule has the same idea with more detail. Radio ads must speak the number and video must show it, and websites must show it on the page. The rule exempts promotional gifts such as pens, cups and clothing, and permanent signs at the business location that prominently show the name (OAR 812-003-0120). See our Oregon page.
Hawaii: name and number
Hawaii's rule asks that an ad name the licensee as licensed and show the license number. The rule defines media to include newspapers, radio, television, the Internet and directories such as yellow pages (Haw. Code R. 16-77-83). Use the exact name on your license. A trade name you use needs to be filed with the board. See our Hawaii page.
Arizona: the "ROC" prefix and a shortcut
In Arizona, the statute says the license number must be preceded by "ROC." It applies to published advertising, letterheads and customer documents. For broadcast, internet and billboard ads, the number is not required if the ad includes a web address that directly links to a site that prominently shows the licensee's name and license number (A.R.S. 32-1124). The statute says a violation can lead to discipline at the registrar's discretion. Your own website is simpler: put "ROC" and the number in the footer. See the Arizona page.
Florida: ads, signs and vehicles
Florida's contractor FAQ says certified and registered contractors must include the license number on building permit applications, offers of service, proposals, bids, contracts, advertisements, signs and certain vehicles. A vehicle needs it when it shows the contractor's name or graphics that would lead a reasonable person to think it is used for construction. Pens, hats and shirts are excluded (Florida DBPR).
One Florida caution. The FAQ page does not list general concrete work among its state license types. It lists a structural pre-stressed, precast concrete specialty. It does not say which license covers a driveway crew. Ask the department which license covers your work. See the Florida page.
Minnesota and Pennsylvania: residential and home improvement numbers
Minnesota's statute says a licensee's number must appear in its advertising, including signs, vehicles, business cards, display ads, flyers, and websites and Internet ads (Minn. Stat. 326B.87). That rule applies to people who hold a license under that statute. Ask the state whether your type of concrete work needs one. See the Minnesota page.
Pennsylvania has no general contractor license. It has a home improvement contractor registration from the Attorney General. The AG's FAQ says contractors must put their registration number in advertisements, contracts, estimates and proposals, and that a vehicle shows the number only if it carries advertising for the business. Contractors whose home improvement work totals less than $5,000 a year are exempt (Pennsylvania Attorney General). See the Pennsylvania page.
Do concrete contractors need a license at all?
It depends on the state and on the size of the job. A few examples we could confirm:
| State | What we confirmed |
|---|---|
| California | A license is needed when the total cost of one or more contracts on the project is $1,000 or more, or when a permit or workers are involved. The small-project exemption does not allow you to advertise as licensed, and jobs may not be broken into pieces under $1,000. (CSLB). Concrete work has its own C-8 classification (CSLB: C-8 Concrete Contractor). |
| New Mexico | Concrete is its own classification, GS-4, covering mixing, pouring, placing and finishing concrete, including curbs, gutters, sidewalks and driveway culverts on private property. It may not do this work in public rights-of-way unless subcontracted to a GA licensee (14.6.6 NMAC). |
| North Carolina | A general contractor license is required for projects valued at $40,000 or more (NC Licensing Board for General Contractors). |
| Florida | General concrete work is not listed among the state license types on the DBPR page. Ask the department. (Florida DBPR) |
Do not assume a state has no rule because a small job is exempt. Many exemptions disappear if you advertise as a contractor or if a permit is needed.
What if my state has no advertising rule?
We did not find a rule in every state, and we cannot rule out a city or county rule. Put your number on the site anyway:
- A homeowner can look you up and see you are real. Our hub guide on how to tell if a contractor is legit is the kind of check buyers run.
- It separates you from unlicensed crews working off a phone number.
- Google and AI assistants read pages for facts. A license number in plain text is something they can quote.
- If a city or county adds a rule, you are already covered.
If you hold more than one license, list the one that covers the work you advertise.
How do you add your license number to a concrete contractor website?
Step 1: Get the exact number and name
Copy your license number and business name exactly as they appear on your license, or on the board's lookup page. A trade name must match what the board has on file.
Step 2: Put it in the footer of every page
A line like "Licensed concrete contractor, Nevada License #0000000" in the footer shows on every page without crowding the layout. Use the prefix your state requires, such as "ROC" in Arizona.
Step 3: Put it on the About and Contact pages too
People look there. Add insurance and bond facts only if they are true and current.
Step 4: Match your other ads
Add it to your Google Business Profile description, your Facebook page, your truck, your yard signs, your estimates and your business cards. Keep the number the same everywhere. Our concrete contractor Google Business Profile guide covers the profile. The Google guidance says to leave tagline-style text out of the profile name, so put the number in the description or website field, not the name.
Step 5: Link to the board's lookup if there is one
A link to the state's license check lets a buyer confirm you in one click. Only link to the official page.
Step 6: Review it each renewal
When your license renews or changes class, update the site the same day. An expired number on a site is worse than none.
What about unlicensed work and exemptions?
If you work under a small-job exemption, do not advertise as a licensed contractor. California's board says the small-project exemption requires that you do not advertise yourself as a licensed contractor (CSLB). Oregon's rule bars claiming to be licensed, bonded or insured without a license (OAR 812-003-0120).
Plain advice: do not put "licensed" or "insured" on a page unless it is true today. If you are in doubt, call your board.
Where does the number go with the rest of your site?
The number belongs with other trust signs: a clear phone number, your town, photos of real jobs and real reviews.

Common questions
Does my license number have to be on my website?
In Nevada, Oregon, Hawaii and Minnesota, the sources we read say it must show in advertising, including on websites or the internet. In Florida the board counts internet sites as advertising. In other states it may be a local rule or none. Put it on the site either way.
Does the number go on my truck?
In some states, yes. Florida requires it on vehicles that display the business name or construction graphics. Pennsylvania requires it only if the vehicle carries advertising for the business. Check your own board.
Can a handyman or one-man crew pour concrete without a license?
Some states allow small jobs without a license. California's threshold is $1,000 and Pennsylvania's registration exemption is under $5,000 a year of home improvements, as the sources above say. Many of these exemptions fail if a permit is needed or if you advertise as licensed.
What is the difference between a license and a registration?
A license usually means you passed an exam or met experience rules. A registration may only record your business and insurance. Rules differ by state, and your number goes in the ad either way if the rule says so.
Where do I look up my license number?
On your license certificate, or the board's online lookup. Do not copy it from an old invoice.
