Calling Window

A calling window is the range of hours in the called person's local time when you are allowed to place sales calls.

Federal rules set the basic calling window for telemarketing to consumers: no calls before 8 a.m. or after 9 p.m. in the called party's local time. Both the FCC rules (47 CFR 64.1200(c)(1)) and the FTC's Telemarketing Sales Rule include this limit.

The word that matters is local. If your team is in California and you call a lead in New York at 6 p.m. Pacific, it is 9 p.m. there, and you are at the edge. Calling windows must be set by the lead's time zone, not yours.

Some states are stricter. For example, Florida's telephone solicitation law limits calls to 8 a.m. to 8 p.m. local time, and some states restrict calls on Sundays or certain holidays. Check every state you call into.

Practical steps:

• Store a time zone on each lead, based on address when you have it, not just area code, since people keep numbers when they move.
• Set your dialer or AI agent to enforce the window automatically.
• Choose a narrower internal window than the legal maximum. Calling at 8:55 p.m. is allowed in many places but rarely welcome.

Retry schedules should respect the same window, so a retry never lands outside allowed hours.
