Which of the following must be displayed in all timeshare advertising?

The requirement to display the state approval number in all timeshare advertising is crucial for ensuring transparency and consumer protection. This number indicates that the timeshare project has met the regulatory standards set by the state in which it operates, providing a level of assurance to potential buyers that the offering has been reviewed and authorized by a governing body. Displaying the state approval number helps consumers verify the legitimacy of the timeshare offering and protects them from fraudulent schemes.

Although developer contact information, estimated completion dates, and salesperson names can be important for consumer inquiries and decision-making, they are not mandated by law in every jurisdiction as essential elements of advertising. Each state may have different regulations, but the inclusion of the state approval number serves as a standardized measure for consumers to confirm that a timeshare property complies with legal requirements, helping to promote informed purchasing decisions.
