Contractor license numbers in social media ads: the rules in 6 states
Updated 25 October 2026 · Written by Reyansh Juneja and Naman Dhiman, the co-founders of SOVE7GN, who run the campaigns and review the clips
Florida's contractor advertising rule is short: your registration or certification number must appear in each advertisement "regardless of medium", and the licensing board's definition of advertising covers "any electronic media including Internet sites". California, Arizona, Oregon, Washington and Nevada have similar rules, so if your posts offer your services, the safe default is to put your license number in your bio, in the caption and on the video itself.
Short answer: In the six states below, a contractor's license or registration number belongs in advertising, and online posts that solicit work are treated as advertising or very likely to be. Put the number in your profile bio, in the caption of every clip that offers your services, and as a line on the end card of the video. Oregon's rule says video ads must show the number visually, and California counts any post that solicits business on the internet as advertising.
Which states require a license number in social media ads?
| State | The rule | Online and video | Source |
|---|---|---|---|
| Florida | The registration or certification number must appear in each offer of services, bid, contract or advertisement, regardless of medium. Business stationery and promotional novelties are excluded. | The board's definition of "advertise" includes "any electronic media including Internet sites". | Fla. Stat. 489.119(5)(b), Rule 61G4-12.011(3) |
| California | Licensed contractors must include their license number in all forms of advertising. First-offense civil penalty: $100 to $1,000. | CSLB lists "any website or post that solicits business on the Internet" as a form of advertising. | CSLB Advertising Guidelines |
| Arizona | The number, preceded by "ROC", goes on all published advertising, bids and customer documents. | Broadcast, internet or billboard ads may skip it if they include a web address that links directly to a site prominently showing your name and license number. | A.R.S. 32-1124(B) |
| Oregon | Business cards, job-site signs and all other written or visual advertising show the CCB number. | Internet advertising must "show visually" the number; video ads must show it visually; radio ads must say it out loud. | OAR 812-003-0120 |
| Washington | All advertising that shows the contractor's name or address must show the current registration number. Penalty up to $10,000; none for an inadvertent error. | Advertising by airwave transmission is exempt from that line. The statute does not single out social media. | RCW 18.27.100 |
| Nevada | All forms of business advertisements must display the license number clearly. | The state board's list includes websites and online directories. | Nevada State Contractors Board (NRS 624.720) |
All six checked at the source in October 2026. Other states, and some trades within these states, have their own rules. Check your own board before you rely on this table.
Does a reel or caption count as advertising?
If it asks for work, assume yes. California's board names posts that solicit business on the internet in its list of advertising. Florida's board rule covers electronic media including internet sites. Oregon goes furthest for video: a video ad must show the number on screen, not only in the caption. We found no exemption in these sources for a post that shows your work without offering it, so drawing that line yourself is a risk with little upside.
A clip of a finished kitchen with the caption "Booking spring projects, link in bio" is an ad. A clip of the same kitchen with no call to action is less clear-cut, but it still promotes your business, and adding the number costs you nothing.
Should the number go in your profile or on every post?
Both, and on the video too. Here is why each layer matters:
| Placement | What it covers | Where it falls short |
|---|---|---|
| Profile bio | Anyone who visits your account | A clip shared or reposted elsewhere loses the bio |
| Caption on each post | The post when seen in the feed | Captions get cut off in previews; a downloaded clip loses them |
| End card or on-screen line | The video itself, wherever it goes | Easy to forget when an editor makes many clips |
Arizona is the one state here that gives a clear shortcut: a broadcast or internet ad can carry a web address that links directly to a site prominently showing your name and ROC number, instead of the number itself. For short clips that are shared off-platform, we would still burn the number into the end card.
When we cut clips for contractors, the license line goes on the end card template once, so every clip carries it without anyone remembering.
What else do these rules say that affects video?
- Advertise only what you are licensed for. CSLB says a contractor cannot advertise work outside its classifications; a C-29 masonry contractor cannot advertise electrical work without a C-10 license (CSLB Advertising Guidelines). If a clip shows a whole remodel, do not caption it as if you did trades you are not licensed for.
- Do not say you are bonded. CSLB's guidelines say the law prevents California contractors from noting in advertising that they are bonded, because consumers may think a bond protects them more than it does. Keep "licensed and bonded" out of captions and voiceovers in California.
- No false or misleading claims. California makes deceptive advertising to win improvement contracts a misdemeanor. Before and after clips must show the same project.
- Vehicles. CSLB requires the business name and license number on commercially registered vehicles, so a truck in the shot should already carry it.

Where does this fit in a clip plan?
License rules are one line on an end card, but they apply to every clip, which is why we set them once at the start. The build-stage clip map is on home builder social media ideas, the pool version is on pool builder marketing, and the service page for builders and remodelers is custom home builder marketing. Remodelers working in older homes should read remodeling contractor marketing, and installers should check solar company marketing for the claims that went out of date in 2026. For the full list of niches we work with, see our page for founder-led businesses. To have clips cut with the license line already on them, book a 30-minute call.
Questions people ask
What are the Florida contractor advertising rules?
Florida requires the contractor's registration or certification number in each offer of services, bid, contract or advertisement, regardless of medium. The board's rule defines advertising to include electronic media and internet sites. Business stationery and promotional novelties such as pens or shirts are excluded.
Does a contractor license number need to be on business cards?
In California and Oregon, yes: both list business cards as advertising. Florida is different, because its statute excludes business stationery from the definition of advertisement, though the number still has to appear on offers of services, bids and contracts.
What is a contractor license number?
It is the number a state board issues when it licenses, certifies or registers a contractor. In Arizona it is shown with the prefix ROC, and in Oregon it is called the CCB number. Customers can use it to look you up on the board's website.
Does a contractor license number have to be on vehicles?
In California, yes: CSLB requires the business name and license number on each commercially registered vehicle, with extra details for some trades. Washington is different, since its statute says vehicle signs are not treated as advertising under its registration number rule.
