What Hours Can You Legally Call Under the TCPA?

By Carrier Fence · September 14, 2026 · 5 min read

A number can pass every DNC and honeypot check and still be an illegal call — if you dial it at the wrong hour. Time-of-day restrictions are one of the simplest TCPA rules to comply with, and one of the easiest to get wrong at scale.

The rule

Telemarketing calls are restricted to between 8:00 a.m. and 9:00 p.m., measured in the called party's local time — not the time zone your call center is operating in. That distinction is where most violations actually happen.

The timezone trap

A call center in the Eastern time zone dialing at 8:30 p.m. local time is calling numbers in the Pacific time zone at 5:30 p.m. — perfectly fine. But run that same campaign later in the evening, and calls that are legal for Eastern-zone numbers become illegal for numbers three hours behind. Any campaign that dials across multiple time zones needs to calculate the permitted window per number, based on area code or address, not based on a single call-center clock.

This compounds with state law

Some states impose narrower calling windows than the federal 8 a.m.–9 p.m. rule — a few cut off earlier in the evening or start later in the morning. Where a stricter state rule applies, it controls. This is the same pattern we cover in federal vs. state DNC lists — the federal rule is a floor, not a ceiling.

Practical steps

Map each number to a time zone before scheduling calls — area code is a reasonable proxy, though not perfect for numbers that have been ported.
Build the 8 a.m.–9 p.m. window into your dialer's scheduling logic, not into a manual process.
Check whether any state you're calling into has a narrower window, and apply the stricter of the two.
Treat this as a per-call-time check, separate from your DNC and honeypot scrub — a clean number dialed at the wrong hour is still a violation.

Where this fits with scrubbing

Time restrictions and number scrubbing solve different problems — one is about when you can call, the other is about who you can call. Both need to be right for a campaign to be compliant.
