What must tour guides display at all times while on duty?

Tour guides must display a city tour guide license at all times while on duty because this license confirms that they have met the necessary training and legal requirements to conduct tours in the area. This regulation is designed to ensure a standard of professionalism and knowledge, which helps protect tourists and enhances their experience by ensuring they are being guided by someone who is knowledgeable about the city's history, culture, and regulations.

While personal identification can also be important for verification purposes, the specific requirement to display a city tour guide license emphasizes the legal compliance aspect of tour guiding, ensuring that guides are officially recognized and authorized to operate within the city. Other items, such as a company business card or visitor feedback form, do not fulfill this legal requirement and are not mandated for display while providing tours.
