Do Masonry Contractors Need a License Number on Their Website?

By Ansh Singh · Updated November 8, 2026 · 9 min read

Short answer: Masons in many states must show a license number on their website if they hold a contractor license or registration. Nevada, Oregon, Hawaii, Minnesota and Florida have written rules that put the number in advertising and name websites or the internet. Arizona has its own version. Where no rule exists, put the number in your footer anyway.

A license number is the number a state board, or sometimes a city or county, gave your business when it licensed or registered you. For a mason it may be a masonry specialty license, a general or residential contractor license, or a home improvement registration. Which one depends on your state and often 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 masonry is licensed in very different ways from state to state. Check with your own board before you rely on this. It is not legal advice.

Is a website "advertising" for a mason?

Mostly, yes. If a page says you build stone veneer, repair brick and chimneys, 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, and says all forms of business advertising must display the number clearly (Nevada State Contractors Board: Advertising requirements).
• Oregon's rule says internet advertising, including website advertising, must show the contractor's license number visually (OAR 812-003-0120).
• Florida's contractor FAQ says "advertise" covers electronic media and explicitly includes internet sites (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 advertising rule and opened the official source. The rules apply to the license you hold, whatever trade it covers. Most do not say "masonry."

That is not the full list. We checked 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, Oregon and Hawaii: the clear website rules

Nevada's advertising page tells contractors that all business advertising must display the license number clearly, and its list of channels includes the website. It refers readers to NRS 624.720 for the details (Nevada State Contractors Board). If you lay brick out of Las Vegas or Reno, the number goes in your footer, on your trucks and on your estimates. Our Nevada page covers more of that market.

Oregon asks that internet advertising, including a website, show the number so a visitor can see it (OAR 812-003-0120). A number buried in a PDF is a poor fit for "show visually." Put it in text on the page. See our Oregon page.

Hawaii asks that an ad name the contractor as licensed, using the name on the license or a trade name filed with the board, and show the number. The rule defines media to include newspapers, magazines, radio, television, the Internet and directories, and says the list is not exhaustive (Haw. Code R. 16-77-83). Use the exact business name from your license.

Arizona, Minnesota and Florida

Arizona has a format rule. The number must be preceded by "ROC" and appear in published advertising and in letterheads and other documents used to talk to customers. For broadcast, internet and billboard ads, the number does not have to be in the ad itself if the ad includes a web link to a site that prominently shows your name and license number (A.R.S. 32-1124). If your own website is that site, the footer does the job.

Minnesota's statute says a licensee's number must appear in any advertising by that licensee, and its examples include websites, internet ads, signs, vehicles, business cards, flyers and brochures (Minn. Stat. 326B.87). See our Minnesota page.

Florida adds a vehicle rule. The number goes on any vehicle that displays the contractor's name. Promotional items such as pens, hats and shirts are not treated as advertising (Florida DBPR). A mason with a box truck full of scaffold and a company name on the door should check that one first.

How is masonry itself licensed?

Masonry is a named trade in some states and sits inside a general license in others. Three examples we could confirm:

• California. The Contractors State License Board lists C-29 Masonry Contractor as a specialty classification (CSLB: Licensing classifications). A license is needed when a building permit is required, when you use additional workers, or when the total cost of one or more contracts on the project is $1,000 or more in labor and materials. The board says you cannot split a bigger job into small contracts to dodge the rule (CSLB: Before applying for a license).
• Utah. Classification S230 covers masonry work. Its scope includes the construction, fabrication and installation of natural or synthetic stone, brick, block, tile and similar masonry or ceramic materials (Utah Admin. Code R156-55a-301).
• South Carolina. Masons are a residential specialty contractor trade. The listing covers installation, alteration and repair of concrete foundations, brick, concrete block and related masonry products, and applies to undertakings that exceed $500 (South Carolina LLR: Residential specialty contractors).

Many other states have no state masonry license, and some leave it to cities and counties. Your own board's site is the only place to settle it. For a quick look at how a state works, start with our pages for California, Utah and South Carolina.

If you hold a specialty license, which number goes on the site?

List the license that covers the work you sell. A mason who also holds a general license should lead with the one that matches the job pages. Keep the format the board asks for: Arizona wants "ROC" in front, Hawaii wants the name as licensed. Do not add a number you do not hold, and do not list one that has lapsed.

What if my state has no rule?

Put your number on the site anyway:

• Homeowners can look you up and see you are real. See the checks in our guide on how to tell if a contractor is legit.
• It separates you from the unlicensed person working from a phone number and a truck.
• Search engines and AI assistants read pages for plain facts. A license number in plain text is something they can quote.
• If a city or county adds a rule later, you are already covered.

Our own advice, not a legal rule: if the board has a lookup page, link to it from your footer so a customer can check you in one click.

How do you add your license number to your masonry website?

Find the exact format your board wants

Open your license record or your board's advertising page. Copy the business name and number exactly as they appear. Note any required prefix, such as "ROC" in Arizona.

Put it in the footer of every page

The footer shows on every page, so a visitor on a fireplace page and a visitor on a contact page both see it. Use text, not an image, so search engines and AI tools can read it.

Add it to your About and contact pages

Say the full line once on your About page (see what a masonry website should include): business name, license type and number. A short version near the phone number on the contact page helps a nervous homeowner. Our guide to your service-area pages shows where else it fits.

Match your truck, cards and estimates

Many boards cover vehicles, cards and written bids as well as websites. Florida, for one, includes vehicles that show the business name. Make the website, the truck lettering and the estimate form all say the same thing.

Match your Google profile

If your Google Business Profile sells your services, treat it like an ad and use the same name. A different name on the license and on the profile invites questions.

Check it twice a year

Licenses renew. When yours does, update the number if it changed and check that the site still lists the right class.

Does the rule cover Google, social media and flyers?

The rules we read say "all advertisements," "all forms of advertising," or list items such as websites, vehicles and cards. None of the pages we opened named Google Business Profile or social media pages. That gap is not permission. If you run a Facebook page or a Google profile that sells your work, put the number there too. Photos of finished jobs help a license line feel real, as we explain in our guide to masonry project photos.

Hawaii's list is open ended. Arizona's rule applies to letterheads and other documents sent to customers. A job flyer left on a door is advertising by any plain reading.

Common questions

Do masons need a license number on their website?

In states with a written advertising rule, such as Nevada, Oregon, Hawaii and Minnesota, yes, if you hold a contractor license or registration. Other states may not require it but nothing stops you from listing it. Check your board.

Is a number on my truck enough?

No. Boards that cover vehicles usually cover other advertising as well. Florida's rule lists vehicles and advertisements separately, and Nevada lists vehicles and the website separately. Put the number on both.

What if I work in a state with no mason license?

You may still need a home improvement or general registration, or a city or county license. If you hold one, that number is the one to show. Ask your state board or city building office what applies to your size of job.

Can I use my business name and number on the site if I only work as a subcontractor?

Rules for subcontractors vary. Some states let subs work under the contractor's license, and some require their own. If you sell directly to homeowners on your site, check with your board whether your own number is required.
