Is cold calling legal in the United States?
Yes, with limits. Manual single-line dialing to a business contact who has not registered on the Do Not Call list is allowed under federal law. Auto-dialed calls or pre-recorded messages to mobile numbers without prior express consent are regulated by the Telephone Consumer Protection Act, with statutory damages of five hundred to fifteen hundred dollars per call. Several states, including Florida and Washington, have stricter mini-TCPA rules. Honor opt-out requests immediately, and maintain an internal suppression list.
