Should your website show your license number and insurance?
If you hold a license, showing the number usually helps, because a customer can check it with the state quickly. In Florida, contractors registered or certified with the state's Construction Industry Licensing Board must put that number in their offers, bids, contracts and advertisements (as the board's rule defines them), and on vehicles that carry the business name. Mention insurance only if a current policy covers the work, and be ready to show proof. This is a plain summary, not legal advice.
How customers check a license
In Florida, the Department of Business and Professional Regulation's license search lets anyone look up professions and businesses the department regulates by name, license number, city or county, or license type. The same portal links to options to verify a licensee and file a complaint.
Other states usually run their own lookup through a licensing board. Showing the exact name the license is held under, next to the number, can make the check quicker for a customer.
Florida's rule for contractors
Section 489.119(5) of the 2026 Florida Statutes says the registration or certification number of each contractor shall appear in each offer of services, business proposal, bid, contract or advertisement, "regardless of medium, as defined by board rule". If a vehicle carries the contractor's name, or text or artwork suggesting it is used for contracting, the number must be displayed clearly with it. The section says stationery and promotional items such as pencils and clothing are not advertisements, and that the board issues a notice of noncompliance for a first offense and may fine or cite a contractor who does not correct it within 30 days.
This covers contractors registered or certified under that part of Florida's contracting law, with numbers from the Construction Industry Licensing Board. It is not a rule for every business, and other licensed trades and professions may have different rules. This is a plain summary, not legal advice.
What the rule does not do
It does not make any business put signs on its vehicles; the statute says the vehicle paragraph does not create a mandatory signage requirement. And it leaves the detailed definition of advertising media to the board's rule, which this summary does not cover, so a contractor should check that rule or ask a lawyer about a specific ad.
Mentioning insurance honestly
The same subsection lets a local government fine a person who is not registered or certified under that part for claiming to be licensed without a valid local license, or for claiming to be insured when general liability or workers' compensation insurance does not cover the work.
As general advice: say you are insured only while a current policy covers the work you advertise, and keep proof ready, since many customers ask for it before a job starts. The related answer on About pages says to mention licenses only if you can produce them, and the related answer on trustworthy websites covers where contact and trust details belong.

Websites, upgraded or built
Most businesses do not need a new website. They need the one they have to load fast, say clearly what they do and ask the visitor to take one step.
