Calls may only be placed between 8:00 AM and 9:00 PM in the recipient's local time zone. Calling outside these hours is a per-call violation of the FTC TSR and TCPA.
The FTC Telemarketing Sales Rule (TSR) and TCPA both prohibit outbound telemarketing calls before 8:00 AM or after 9:00 PM local time. 'Local time' means the time zone of the number being called based on its area code and exchange — not the time zone of the call centre. Auto dialers must incorporate geographic time-zone mapping to ensure every call is compliant, regardless of where the agent or server is located.
Florida: 8:00 AM – 8:00 PM, no calls on Sundays. California: 8:00 AM – 9:00 PM but with stricter holiday restrictions. Indiana: 8:00 AM – 9:00 PM with county-specific nuances. New York: 8:00 AM – 9:00 PM but AG enforcement is aggressive. Wyoming: 8:00 AM – 9:00 PM. Always verify state Attorney General guidance for any state where you run significant volume — several states issue additional guidance that differs from the bare statutory text.
Area code + exchange (NPA-NXX) geolocation is the standard method for determining recipient time zone. A dialers NPA-NXX database must be current — phone number portability means area codes don't always reflect geographic location. The most accurate approach combines area code lookup with any available ZIP code or address data from the CRM. Klozer.io applies real-time time-zone logic to every number in the campaign queue and suppresses out-of-window calls automatically.
