The Federal Trade Commission gives consumers a choice about whether they want to receive most telemarketing calls. Consumers can put their phone numbers on the national "do not call" registry provided by the FTC. It is illegal for most telemarketers or sellers to call a number listed on the registry. It is important for you and others at your dealership to know when it is appropriate to call clients. This lesson is designed to teach dealership employees the rules and best practices for calling consumers.
