What is Quiet Hours?

Quiet hours are the times of day — typically early morning and evening, such as before 8am or after 9pm local time — when regulations prohibit placing marketing calls or sending marketing texts to consumers. The key nuance is that they're based on the recipient's local time zone, not yours, so a compliant outbound system has to know where each contact is and hold messages until an allowed window.

Quiet-hours rules come mainly from the TCPA in the U.S. and from various state and international laws, and violating them exposes you to the same per-contact penalties as other TCPA breaches. They apply to voice and SMS in particular.

This is why calling and texting platforms enforce quiet hours automatically — queuing outbound touches by the contact's time zone and releasing them only during permitted hours.
