Contractor license number on vehicle

Some states make a contractor show the license number on the work truck. Florida ties the number to any vehicle that carries the contractor's name or contracting art. California sets a size for the number on every vehicle with a commercial registration used in the business.

This guide sums up each rule from the source text and shows layouts that make room for the number. This guide is not legal advice. Rules change. Check the current rule with your state, city, or licensing board before you print.

Florida: the number goes with the name

Florida Statutes 489.119(5) covers registered and certified contractors (Fla. Stat. 489.119).

Ads and bids. The license number must appear in each offer of services, proposal, bid, contract, or ad.
Vehicles. If a vehicle shows the name of a contractor or business, or text or art that would lead a person to think it is used for contracting, the license number must be shown with the name, text, or art. The statute says it must be displayed so it stands out and can be read.
Local numbers. Local governments may ask contractors with a local license to show their local license numbers on top of the state number.
No sign mandate. The statute says this paragraph does not create a mandatory vehicle signage rule. An unmarked truck needs no number.
Stationery. Business stationery and promotional novelties such as pens and shirts are not ads.
Penalty. The board issues a notice of noncompliance for a first offense. It may fine or cite a contractor who does not fix it within 30 days, or for a later offense.

California: name and number on each work vehicle

California Business and Professions Code 7029.6 asks each licensed contractor to show the business name and license number on each vehicle with a commercial registration used in the construction business. The text must be easy to see, in print type of 72 point or 3/4 inch in height and width (BPC 7029.6).

Plumbing (C-36), sign (C-45), and well drilling (C-57) contractors fall under section 7029.5. They show the name, permanent business address, and license number on each side of each vehicle, in letters and numerals 1 1/2 inches high or taller. The rule covers water well drill rigs. Failure to comply is a cause for discipline (BPC 7029.5).

The Contractors State License Board reminds contractors to put the license number on vehicles and ads (CSLB bulletin 20-21). Its civil penalty table in 16 CCR 884 lists $500 to $8,000 for a 7029.6 violation (CSLB civil penalty table).

Texas and other states

Texas has its own license line rule for HVAC trucks. Read the license section of DOT number decal requirements. We did not check other states for this guide. Ask your state licensing board.

Layouts with room for the number

Each image is a free watermarked WrapMockup preview. Every company is fictional, and the license lines are placeholders. Use your real name and number.

Pickup for a Florida roofer

Minimal lettering pickup concept for Gulf Coast Roofing, a fictional company, with a placeholder license line

The license line sits with the name and phone. That is what the Florida rule asks for. The preview sets it small, next to the website. Ask your shop to size it so it stands out and reads with ease.

Van for a Florida HVAC company

Two-tone van concept for Sunline Air and Heat, a fictional company, blue lower half, with a placeholder license line

A Florida HVAC van with the company name needs the license number with it. Put it on both sides and the rear doors, where the name appears.

Pickup for a California builder

Color block pickup concept for Redwood Build Co, a fictional company, green and yellow, with a placeholder CSLB license line

California asks for the business name and license number in 72 point type or 3/4 inch letters. On the real truck, set the license line to that size or larger.

Checklist before you print

Use the number from your license. Copy it from the board record, not from memory.
Put it next to the name. In Florida the number goes with the name, text, or art.
Size it to the rule. In California use 72 point or 3/4 inch for most trades, and 1 1/2 inches for C-36, C-45, and C-57.
Add the address if your trade needs it. California plumbing, sign, and well drilling contractors show the permanent business address.
Check your city. Florida cities and counties may ask for a local license number.
