Are Power Dialers Illegal? TCPA and FTC Rules

No. Power dialers are legal in the United States, and they carry less regulatory risk than predictive dialers for a structural reason rather than a legal exemption. A power dialer places one call per available rep, so it never dials ahead of your people and cannot produce an abandoned call, which is the event the FTC three percent cap actually counts. It also generally falls outside the Supreme Court definition of an autodialer, because it works a stored list of specific numbers rather than a random or sequential number generator. What remains is everything else: Do Not Call scrubbing, the 8:00 a.m. to 9:00 p.m. residential calling window in the recipient time zone, consent, a ten business day deadline to honor revocations, and five years of per-call records.

The question comes up because sales leaders hear "auto dialer" and "TCPA" in the same sentence and assume the whole category is radioactive. It is not. But the parts of the law that do apply to power dialing are not the parts most vendor pages talk about, and one of them changed in 2025 and again in January 2026.

Why a power dialer sits in a different risk class from a predictive dialer

Start with the mechanism, because the legal difference follows directly from it.

A power dialer places exactly one call for each available rep and advances to the next record when that call ends. There is always a human on your side waiting. A predictive dialer opens several lines per available rep based on a live forecast of when reps will free up, deliberately dialing ahead of availability to raise talk time per agent hour. When that forecast overshoots, a real person answers a call with nobody behind it.

That event has a definition in federal law. Under the FTC Telemarketing Sales Rule at 16 CFR 310.4(b)(1)(iv), an outbound call is abandoned if a person answers it and the telemarketer does not connect the call to a sales representative within two seconds of that person completed greeting. Two seconds, measured from the end of their hello. The safe harbor at 310.4(b)(4) then permits abandonment of no more than three percent of all calls answered by a person, measured over a single campaign of under 30 days or separately over each successive 30-day period.

A one-call-per-rep dialer does not generate that event in normal operation. So the cap that dominates every compliance discussion about outbound dialing is, for a power dialer, largely beside the point. That is the real answer to why this category is treated as the safe option, and it is worth understanding as mechanics rather than folklore, because it also tells you when the protection stops: if you bolt a parallel dialing add-on onto your power dialer and start opening ten lines for one rep, you have moved yourself back into abandoned-call territory. The mode-by-mode comparison is in predictive dialer vs power dialer, and the published prices for each mode are on power dialer software and predictive dialer software.

Is a power dialer an autodialer under the TCPA?

Usually not, and this is the second reason the category is lower risk.

The TCPA restricts calls made with an "automatic telephone dialing system", or ATDS, and for years plaintiffs argued that almost any calling software qualified. In Facebook v. Duguid (2021) the Supreme Court read the statutory text narrowly: an ATDS is equipment that has the capacity to store or produce telephone numbers using a random or sequential number generator. A power dialer working through a list of specific, known numbers your team assembled is not generating numbers randomly or sequentially, so in most configurations it falls outside that definition.

Two cautions before you file that away as settled. First, it removes one theory of liability and only one. Duguid said nothing about the Telemarketing Sales Rule, nothing about the national Do Not Call registry, nothing about consent, and nothing about state law. Several states have their own mini-TCPA statutes with their own definitions, and a call that is fine federally can still be a problem in a particular state. Second, if any part of your stack uses prerecorded or artificial voice messages, the ATDS analysis stops mattering, because the prerecorded-voice prohibition in the TCPA applies regardless of what dialed the number.

Are auto dialers illegal?

No, and the framing of the question is the problem. "Auto dialer" is an umbrella term covering preview, progressive, power, parallel and predictive modes. None of them is banned. What is regulated is the conduct: who you call, when you call, what you say, whether you had permission, whether you connected a human, and whether you kept the records.

Here is how the modes actually line up on risk.

Dialing mode	Lines per available rep	Can it abandon a call?	Subject to the FTC 3% cap in practice
Preview	One, triggered manually by the rep	No	Not in normal operation
Progressive	One, placed automatically on wrap-up	No	Not in normal operation
Power	One, placed automatically at speed	No	Not in normal operation
Parallel	Several, commonly up to ten, extras dropped on connect	Yes	Yes
Predictive	Several, based on a live forecast	Yes	Yes

Everything below the line in that table needs the full four-part safe harbor: the three percent cap, ringing for at least fifteen seconds or four rings, a prompt recorded message giving the seller name and telephone number whenever no rep is available, and records proving all three. Everything above the line still needs everything in the next two sections.

What still applies to a power dialer, whatever the mode

This is the part that catches teams, because it is unglamorous and none of it depends on your dialing mode.

• Calling hours. Section 310.4(c) restricts calls to a residence to between 8:00 a.m. and 9:00 p.m. local time at the called person location, not where your office is. A dialer working a national list without time zone gating will break this on the first shift.
• Do Not Call. Registry scrubbing and your own internal suppression list are unaffected by how the call was placed. Business-to-business calls sit outside much of the DNC framework, which is covered in Do Not Call list rules for businesses.
• Records, for five years. Section 310.5 requires a per-call record including who placed it, the seller, the good or service, whether the recipient was a consumer or a business, whether a prerecorded message was used, the calling and called numbers, date, time and duration, the script used, the caller ID number and name transmitted plus proof of authorization to use them, and the disposition of the call.
• Caller ID. Transmitting a number that is not yours to use, or that cannot receive a return call, is its own problem, separate from anything about dialers.

The recordkeeping condition deserves more attention than it gets, because it is the one that fails quietly. Consent, suppression and disposition data typically pass through a CRM, a dialer, a list vendor and a data warehouse before anyone tries to audit it, and five years later the question is not just what the record says but where it came from. If you cannot trace a consent record back through every system it moved through, you have a record you cannot defend. Build that trail while the data is fresh, not when a regulator asks.

The consent revocation rule that catches power dialing teams

This is the requirement most likely to be out of date in your process, and it has nothing to do with dialing mode.

The FCC rule at 47 CFR 64.1200(a)(10) has been in force since April 11, 2025. Read the current text and three obligations fall out of it. A called party may revoke consent by any reasonable method. You may not designate an exclusive means of revoking. And every revocation request must be honored "within a reasonable time not to exceed ten business days from receipt of such request."

The rule also lists methods that count as reasonable per se, and the list is specific: an automated interactive voice or key-press opt-out on a call; a reply to a text message using the words "stop", "quit", "end", "revoke", "opt out", "cancel" or "unsubscribe"; or a website or telephone number you designated to process opt-outs. If a reply text uses different words, you must still treat it as valid if a reasonable person would understand it as a revocation. Section 64.1200(a)(11) goes further: revocation by other means, such as a voicemail or an email to a number or address intended to reach you, creates a rebuttable presumption that consent was revoked. And under (a)(12) you may send exactly one confirmation text, provided it contains no marketing.

One part of this has been deferred, and vendors get it wrong in both directions. The broader "revoke-all" element, under which a single revocation would stop that caller contacting the person about unrelated matters too, was pushed back by FCC order of January 6, 2026 to January 31, 2027, while the Commission considers comments on whether to modify it. Everything described above is already live. Deferring your whole opt-out project because you read that the rule was delayed is a misreading of what was delayed.

What happened to the one-to-one consent rule?

It was vacated. In Insurance Marketing Coalition Ltd. v. FCC, No. 24-10277, decided January 24, 2025, the Eleventh Circuit held that the FCC exceeded its statutory authority when it required prior express written consent to be obtained one seller at a time, with follow-up contact "logically and topically associated" with the original interaction. The court reasoned that the TCPA requires prior express consent and does not authorize the Commission to add conditions on top of it, and vacated that part of the 2023 order.

If you buy shared or aggregated leads, that decision materially changed what would otherwise have landed on you. It did not make lead buying consequence-free. You still need prior express written consent for marketing calls using a prerecorded or artificial voice or an ATDS, you still need to be able to produce the consent record for a specific consumer, and state mini-TCPA statutes were untouched by an interpretation of the federal statute.

What are the penalties?

Source	Amount	Who brings it
FTC Act Section 5(m)(1)(A), per 16 CFR 1.98	Up to $53,088 per violation	The FTC, for Telemarketing Sales Rule violations
TCPA, 47 U.S.C. 227(b)(3)	$500 per call, up to $1,500 if willful or knowing	Private plaintiffs, including class actions
State mini-TCPA statutes	Varies by state	State attorneys general and private plaintiffs

We confirmed the $53,088 figure against the August 6, 2026 issue of the eCFR; it carries the adjustment published on January 17, 2025, and the FTC revises the table each January. The number that should worry a high-volume operation is not the headline but the multiplier: each call can be charged separately, and the TCPA private right of action is what turns a configuration error into a class action rather than a fine.

Does it matter if an AI voice makes the call?

Yes, in one direction. The FCC confirmed in February 2024 that AI-generated voices in calls fall under the TCPA, which means an AI caller is treated as an artificial voice and the consent requirements attached to artificial and prerecorded voice apply. Nobody gets a technology exemption here, and any vendor implying otherwise is selling you a problem.

What changes is the abandoned-call side of the analysis, for the same structural reason a power dialer is lower risk. If the AI agent holds the conversation itself, there is no queue of reps to pace toward, so there is no forecast to overshoot and every answered call has something on the other end. That removes the three percent exposure and the recorded identification message requirement, both of which exist only because a person might answer and find nobody there. It removes nothing else. We set out the full position in is AI cold calling legal and on TCPA compliant AI calling.

A compliance checklist before you buy a power dialer

Take this to the demo. Any vendor worth buying from will answer all of it without flinching.

• Does the dialer gate calls by the recipient time zone, or by the account time zone?
• Does it scrub against the national registry and an internal suppression list on every campaign, and how often is the registry data refreshed?
• Can it record a revocation received by any channel, and does it stop calls within ten business days automatically rather than by manual ticket?
• Does it write a disposition to every call, and can you export dispositions per campaign per 30-day window?
• Does it retain caller ID transmitted and proof of authorization alongside the call record?
• How long is call and record retention, and is five years available without an extra archive fee?
• If parallel dialing is offered as an add-on, does turning it on change your abandoned-call obligations? The answer is yes, and the vendor should say so.

Two of those come with a price tag attached that rarely appears in a comparison table, so ask early. Our audit of thirteen platforms, with what each one publishes and where the dialer actually sits in the pricing, is on power dialer software, and the wider category view is on auto dialer software and outbound call center software.

The short version

Power dialers are legal. They are lower risk than predictive dialers because one call per rep cannot abandon a call, and lower risk under the TCPA because a stored list of specific numbers is generally not a random or sequential number generator after Facebook v. Duguid. Neither of those facts touches Do Not Call, calling hours, consent, or records. The obligation most likely to be wrong in your process today is the revocation rule: any reasonable method, no exclusive channel, ten business days, in force since April 11, 2025, with only the revoke-all element deferred to January 31, 2027. Fix that before you worry about the dialing mode.
