AI Calling Hours: Federal and State Time Limits
When an AI agent may place outbound calls: the federal 8 a.m. to 9 p.m. rule, stricter state windows like 8 p.m. cutoffs, time zones, and call frequency caps.
AI agents placing sales calls must stay between 8 a.m. and 9 p.m. in the called person's local time under federal rules, and several states set a tighter window, commonly 8 a.m. to 8 p.m. The safest policy for any business using AI outbound calls is to call only during the narrowest window that applies to the states you dial, in the recipient's time zone.
AI calls are treated like any other artificial-voice call under the TCPA, so the same timing rules apply. See AI outbound calls and the TCPA for the wider framework. This is general information, not legal advice.
The federal rule
Two federal rules set the same window:
- TCPA rules (FCC): 47 CFR 64.1200(c)(1) bars telephone solicitations to residential subscribers before 8 a.m. or after 9 p.m. local time at the called party's location.
- Telemarketing Sales Rule (FTC): the TSR uses the same 8 a.m. to 9 p.m. window for telemarketing calls, measured at the called person's location.
Strictly, these are written for solicitations. Informational calls like appointment reminders aren't covered by the federal hour rule, but people don't distinguish when the phone rings at 9:40 p.m., and complaints follow. Apply the window to every AI call.
Stricter states
Several states have "mini-TCPA" laws with tighter limits. Examples:
| State | Calling window for solicitations | Frequency cap |
|---|---|---|
| Federal baseline | 8 a.m. – 9 p.m. | None federally |
| Florida | 8 a.m. – 8 p.m. | 3 calls per 24 hours on the same subject |
| Maryland | 8 a.m. – 8 p.m. | 3 calls per 24 hours on the same subject |
| Oklahoma | 8 a.m. – 8 p.m. | 3 calls per 24 hours on the same subject |
Florida's limits are in section 501.616 of the Florida Statutes. Maryland's Stop the Spam Calls Act took effect January 1, 2024, and presumes a call to a Maryland area code is a call to a Maryland resident. Other states have their own variations, including some restrictions on Sundays and holidays. Before calling into a state at volume, look up its current rules.
Time zones are where mistakes happen
The window is measured at the recipient's location, not yours. Common traps:
- Area code isn't location. People keep their numbers when they move. A 305 number might belong to someone now living in Seattle.
- States with multiple time zones. Florida, Texas, Tennessee, Kentucky, Indiana and others span two zones.
- Arizona doesn't observe daylight saving time (except the Navajo Nation), so its offset from other states changes twice a year.
- Canada has six time zones, including Newfoundland's half-hour offset.
A practical rule: if you don't know where someone lives, use a window that's safe for every US time zone. 11 a.m. to 8 p.m. Eastern is 8 a.m. to 5 p.m. Pacific, which fits the federal window and the stricter 8 p.m. states for anyone in the continental US. Hawaii and Alaska need their own check.
Frequency limits
The states with three-calls-per-24-hours rules count calls "on the same subject matter or issue," regardless of the number used. An AI agent that retries a no-answer call every hour breaks that quickly. Set a retry policy before launch:
- No more than one AI attempt per person per day for the same purpose.
- Space retries at least a day apart.
- Stop after a set number of attempts (three is common).
- Leave one voicemail, not one per attempt.

Building a calling-hours policy
Write it down. A one-page policy protects you and keeps the team consistent:
- Window: "AI calls only between 9 a.m. and 7 p.m. in the recipient's local time, Monday to Saturday."
- Unknown location: "If we don't have an address, call only between 12 p.m. and 7 p.m. Eastern."
- Holidays: "No AI calls on federal holidays."
- Frequency: "One attempt per day, three attempts maximum per purpose."
- Owner: who checks compliance and how often.
A window narrower than the law allows also tends to reach people at better times. Few customers want a sales call at 8:05 a.m.
Worked example: one list, three time zones
A home services company in Atlanta wants its AI agent to call 120 customers who asked for a fall maintenance reminder. The list includes addresses, so time zones are known:
| Customer location | Count | Local window used | Eastern-time equivalent |
|---|---|---|---|
| Georgia (Eastern) | 80 | 9 a.m. – 7 p.m. | 9 a.m. – 7 p.m. |
| Alabama (Central) | 30 | 9 a.m. – 7 p.m. | 10 a.m. – 8 p.m. |
| Florida Panhandle (Central) | 10 | 9 a.m. – 7 p.m. (inside Florida's 8 p.m. limit) | 10 a.m. – 8 p.m. |
Rather than manage three windows, the company runs every call between 10 a.m. and 7 p.m. Eastern. That's inside every customer's local window, inside Florida's tighter limit, and still gives nine hours of calling. Reminder calls are informational, but the company applies the same window anyway.
If the list had no addresses, it would fall back to the "unknown location" window in its policy.
If a call goes out at the wrong time
Mistakes happen: a scheduling bug, a teammate in another time zone, a daylight saving change. When one does:
- Stop the campaign until you know the cause.
- Identify every affected number and the local time each call landed.
- Add an apology note to those contacts so the next person who speaks to them knows.
- Honor any opt-out that came from the call immediately.
- Fix the cause (time zone data, schedule, staff training) and write down what changed.
A documented fix is also part of what regulators look for when deciding whether a violation was an isolated error.
Calling hours checklist for each campaign
- Every number has a known or assumed time zone.
- The campaign runs inside the narrowest applicable window.
- State-specific limits for the states you're calling are applied.
- Retry rules respect any three-per-day caps.
- Holidays are excluded.
- Someone reviews a sample of call timestamps after the campaign.
Inbound calls are different
None of these rules limit when your AI receptionist can answer inbound calls. A caller who rings you at 11 p.m. can be helped by an AI agent at 11 p.m. The rules apply to calls you initiate. Callbacks the caller requested at a specific time are a gray area; scheduling them inside normal hours avoids the question. See having AI call back missed callers.
How Callata handles calling hours
Callata only lets an AI agent place an outbound call between 8 a.m. and 9 p.m. in your business's time zone, set in your account. That matches the federal window for customers in your own zone. It doesn't know where each recipient is, so for customers in other time zones or in states with 8 p.m. cutoffs, start calls inside the narrower window yourself. Every outbound AI call also requires a consent confirmation and is blocked for numbers on your opt-out list.
AI calls use prepaid minutes at $0.25 per minute; Callata Office is $99 a month for five users, plus $20 per additional user. Try Callata.
Frequently asked questions
What time can AI agents make calls?
Federal rules bar telephone solicitations before 8 a.m. or after 9 p.m. in the called person's local time. Several states are stricter, ending at 8 p.m., and some limit how many calls you can make per day.
Whose time zone counts, mine or the customer's?
The called person's. If you're in New York calling someone in California at 8:30 a.m. your time, it's 5:30 a.m. for them, which is outside the window.
Do calling hours apply to appointment reminders?
The federal hour limit is written for telephone solicitations, but calling outside 8 a.m. to 9 p.m. for any reason invites complaints. Keep all AI calls within the most conservative window.
Can an AI agent call on Sundays?
Federal rules don't ban Sunday calls, but some states restrict calls on Sundays or holidays. Check the states you call into.
