Your contractor license number: where it must appear
Statute 489.119(5)(b) says the registration or certification number appears in each offer of services, business proposal, bid, contract or advertisement, regardless of medium as defined by board rule. Rule 61G4-12.011(3) covers business cards, proposals, contracts, construction site signs, newspapers, airwave transmission, any electronic media (including Internet sites), flyers, billboards and signs on vehicles. It does not cover stationery or promotional novelties like pens, balloons or shirts. If your truck shows your name or artwork, the number is conspicuously and legibly displayed there, but that paragraph does not require lettering on the truck.

What the law says (official text)
“The registration or certification number of each contractor shall appear in each offer of services, business proposal, bid, contract, or advertisement, regardless of medium”
In plain words: the number goes in every offer, proposal, bid, contract and ad, whatever the medium.
“The terms "advertise" and "advertises" shall apply to business cards, business proposals, contracts, construction site signs, all newspapers, airwave transmission (other than internal company communications), any electronic media including Internet sites, phone directory, and other media including handbills, billboards, flyers, shopping and service guides (coupon offerings), magazines, classified advertisements, manufacturer's "authorized dealer" listings, and signs on vehicles.”
In plain words: the board rule names cards, proposals, contracts, construction site signs, electronic media and Internet sites, and signs on vehicles. Counting social media as “electronic media” is our reading.
“They shall not apply to balloons, pencils, pens, hats, articles of clothing, shirts, or other promotional novelties.”
In plain words: it does not apply to promotional novelties. Statute 489.119(5)(d) also excludes business stationery.
“The board shall assess a fine of not less than $100 or issue a citation to any contractor who fails to include that contractor’s certification or registration number when submitting an advertisement for publication, broadcast, or printing.”
In plain words: for electrical and alarm contractors, the minimum fine is $100, or a citation.
