Delaware requires nonexempt sellers and telemarketing businesses to register with the Department of Justice before telemarketing to customers in the state, requires opening disclosures and a seven business day cancellation right, and bars willful sales calls for 10 years after a customer says stop.

Unless exempt, no person may do business through telemarketing with a customer located in Delaware, as a seller or a telemarketing business, without first getting a certificate of registration from the Director of the Consumer Protection Unit of the Department of Justice. The application is sworn and notarized and includes representative scripts, and every registrant files a surety bond or, at the Director's discretion, a letter of credit. Exemptions cover certain publicly traded corporations and their subsidiaries, certain nonprofits, sellers under the Public Service Commission, licensed real estate professionals, and other listed sellers.
The chapter does not apply to solicitations or telephone use in connection with a sale of goods or services by a business supplier to a business or between businesses. It also does not apply to solicitations in which the sale is not completed, and payment or authorization for payment is not required, until after a face to face sales presentation to the customer.
At the beginning of the call and before any sales pitch, the telemarketer must say that the purpose of the call is to sell specific merchandise, give its own name and the seller's name, and accurately describe what is offered. Before the initial sales call ends and before payment is requested, it must disclose the total cost, any restrictions or conditions, and the material terms of any refund or cancellation policy. A sale becomes final only seven business days after the customer receives a written cancellation notice. Sales that allow at least seven days to review and return goods or cancel services, with refunds processed within 30 days and the policy disclosed, are exempt from that notice.
Delaware's telemarketing chapter makes it a prohibited practice to willfully call or contact a customer by telephone for any purpose related to selling or advertising merchandise for 10 years after the customer, or someone acting with the customer's authorization, directed the caller orally or in writing to stop. A call is willful if the caller knows or should know of the customer's instruction. The Department of Justice tells consumers who want to stop telemarketing calls to consult the National Do Not Call Registry.
The Department of Justice's telemarketing page tells consumers that under federal and Delaware laws, telemarketing calls are restricted to between 8 a.m. and 9 p.m., and that telemarketers must promptly identify themselves and say why they are calling. The federal rule says no person or entity may initiate a telephone solicitation to a residential telephone subscriber before 8 a.m. or after 9 p.m., local time at the called party's location.
Delaware has two statutes on intercepting communications. The wiretap chapter makes it lawful for a person to intercept a wire, oral, or electronic communication when the person is a party to it or one of the parties has given prior consent, unless the purpose is a criminal or tortious act. The violation of privacy statute in the criminal code makes it an offense, except as authorized by law, to intercept without the consent of all parties a message by telephone or other private means of communication, including private conversation.
Section 2505A says the chapter does not apply to solicitations in which the sale is not completed, and payment or authorization for payment is not required, until after a face to face sales presentation to the customer. The same section exempts sales by a business supplier to a business or between businesses.
Section 2503A requires a certificate of registration, unless an exemption applies, from any person doing business through telemarketing with customers in Delaware as a seller or as a telemarketing business, meaning one that telemarkets for a seller for compensation. A telemarketing business calling for an exempt corporation under a written compliance contract is exempt, unless 25 percent or more of its yearly telemarketing revenue comes from sellers that must register.
Section 2507A makes it a prohibited practice to assist, support, or provide substantial assistance to a seller, telemarketer, or telemarketing business when the person knew or should have known it was violating the chapter. A customer harmed by a violation may recover actual and punitive damages, attorney's fees, and court costs.
