Telemarketing is regulated by the Telephone Consumer Protection Act (TCPA) in the United States, which sets specific restrictions on when telemarketers can make calls. According to the TCPA, telemarketing calls are only permitted between 8 a.m. and 9 p.m. local time of the recipient, meaning the time restrictions are based on the caller's local time zone. Outside of these hours, telemarketers are prohibited from initiating calls to consumers' homes or mobile phones. These regulations are designed to protect consumers from intrusive and unwanted calls during early mornings and late evenings. While telemarketing itself is legal, it must adhere to these strict time restrictions and other rules, such as honoring do-not-call lists and obtaining prior consent.
