Which advertisements are exempt from displaying a contractor's license number?

Free Yellow Page listings are exempt from displaying a contractor's license number because these listings are generally considered to be a part of an informational directory and not a formal advertisement promoting a specific service for commercial gain. Unlike promotional materials that are actively used to solicit business, such as coupons and business cards, Yellow Page listings simply provide a basic entry point for consumers to find service providers without an overt marketing message. This exemption recognizes that these listings primarily serve as a reference tool rather than a direct advertisement.

In contrast, materials like coupons or business cards are actively used to market services and typically must include a license number to ensure that consumers can verify the legitimacy and qualifications of the contractor they are considering hiring.
