Predictive Dialers Under the TCPA: Consent, Duguid, and Damages

Predictive dialers under the TCPA occupy an unusual place: after the Supreme Court’s 2021 decision in Facebook, Inc. v. Duguid, most predictive dialers no longer qualify as “automatic telephone dialing systems,” yet the statute still imposes consent requirements, Do Not Call obligations, prerecorded-voice rules, and caller identification duties that produce serious liability when a campaign gets them wrong. Treating the Duguid decision as a general exemption is the single most expensive mistake a compliance program can make.

Whether a Predictive Dialer Is an ATDS After Duguid

The TCPA defines an automatic telephone dialing system as equipment with the capacity to store or produce phone numbers using a random or sequential number generator and to dial those numbers.¹ Both elements are required. The equipment must generate numbers through randomization or sequential logic, and it must be able to dial the output.

On April 1, 2021, the Supreme Court held that the “random or sequential number generator” phrase modifies both “store” and “produce,” meaning a device must use such a generator to either store or produce the numbers it dials to qualify as an ATDS.² Predictive dialers work by pulling from uploaded contact databases, CRM records, purchased leads, or compiled spreadsheets. They dial fast, but they dial a curated list. Under the current reading, that’s not an ATDS.

Speed and volume are legally irrelevant. What matters is whether the specific software involved has the capacity to generate numbers randomly or sequentially. A plaintiff now carries the burden of proving that the technology used to contact them had that capacity. Without that proof, the ATDS-specific provisions of the TCPA do not apply to the calls in question.

What Still Applies Even When Your Dialer Isn’t an ATDS

Escaping the ATDS definition is not a pass on the TCPA. The statute separately restricts calls that use a prerecorded or artificial voice, and those restrictions apply regardless of what kind of dialing equipment placed the call.¹ A predictive dialer that drops a prerecorded message when no agent is available still triggers TCPA liability if the recipient never consented. That “abandoned call” scenario is common in predictive dialer operations, and it’s a frequent source of litigation.

For wireless numbers and any line where the recipient pays for the call, the statute requires prior express consent before any automated or prerecorded call. Emergency calls and calls to collect debts owed to the federal government are the only statutory carve-outs from the wireless-number restriction. For residential landlines, prerecorded and artificial-voice calls are also prohibited without prior consent, though the FCC has exempted certain non-commercial and non-advertising categories, capped at three prerecorded calls to the same residential line within any 30-day period.³

Automated calls to emergency lines, hospital patient rooms, and similar sensitive locations are banned outright. No level of consent overrides those prohibitions.

Consent Requirements That Govern Predictive Dialer Campaigns

The TCPA sets up two tiers of consent, and which one applies turns on whether the call is telemarketing.

Prior Express Written Consent for Telemarketing

Any telemarketing call or text sent to a wireless number using an ATDS or a prerecorded voice requires prior express written consent. Under FCC rules, that means a written agreement, signed by the person being called, that clearly authorizes the caller to deliver telemarketing messages using automated technology to a specific phone number.⁴ The agreement must include a conspicuous disclosure that the signer is authorizing automated telemarketing calls, and it must state that signing is not a condition of purchasing anything. Electronic and digital signatures count.

This is where predictive dialer compliance most often breaks down. A phone number written on a signup form doesn’t qualify. A buried clause in a terms-of-service agreement the consumer never meaningfully reviewed doesn’t qualify. The consent must be specific to automated marketing calls, and the caller bears the burden of proving it existed when the call was placed.

Prior Express Consent for Non-Telemarketing Calls

Non-telemarketing calls, such as appointment reminders, account alerts, and debt collection calls, require only prior express consent, which is a lower threshold. This is generally satisfied when a consumer voluntarily provides their phone number during a transaction or business interaction. No signature or written agreement is needed, but the caller still must be able to show the recipient gave their number in a context where automated contact was reasonably expected.

Lead Generation Consent

The FCC adopted a “one-to-one consent” rule in late 2023 that would have required lead generators to obtain separate consent for each individual seller or brand. A federal court struck the rule down, and in 2025 the FCC formally removed it from its regulations.⁵ Businesses that purchase leads should still verify that the consent obtained covers their specific company and communication type. Generic or vague consent forms remain a litigation target even without the one-to-one requirement.

Revocation of Consent

A consumer can revoke consent at any time, and the FCC has made it difficult for businesses to restrict how. Callers cannot designate an exclusive opt-out method. The consumer can use any reasonable method that clearly expresses a desire to stop receiving calls or texts.⁴

Certain methods are automatically valid. Replying to a text with “stop,” “quit,” “end,” “revoke,” “opt out,” “cancel,” or “unsubscribe” counts. So does using an automated opt-out mechanism on a robocall, or submitting a request through a website or phone number the caller has designated for that purpose. If a consumer uses any other reasonable method, such as leaving a voicemail or sending an email to an address where they’d reasonably expect to reach the caller, the request creates a rebuttable presumption of valid revocation. The caller must honor it unless they can show it wasn’t reasonable under the circumstances.

Once a revocation is received, the caller has no more than 10 business days to stop all automated contact to that number. Continuing after that window is the kind of conduct courts treat as willful, which triples damages. For high-volume predictive dialer campaigns, the operational point is that opt-out processing and number suppression must move across every active campaign within the 10-day window.

Reassigned Numbers

One of the trickiest TCPA traps is calling a number that used to belong to someone who consented but has since been reassigned to a new subscriber. The new subscriber never agreed to your calls, and the consent from the original subscriber doesn’t transfer.

The FCC’s Reassigned Numbers Database provides a safe harbor. A caller who queries the database before placing a call can avoid liability if the database incorrectly indicates the number has not been reassigned. To qualify, the caller must show three things: valid consent from the original subscriber, a database check before the call, and an incorrect “no” response from the database indicating no reassignment.⁶ Access requires a paid subscription through reassigned.us. For any business running a predictive dialer against an aging contact list, this check is one of the cheapest forms of insurance available.

Do Not Call Compliance

The TCPA’s consent rules and the Do Not Call rules are separate obligations, and satisfying one doesn’t automatically satisfy the other. Any business making telemarketing calls must scrub its call lists against the National Do Not Call Registry. The FTC requires telemarketers to update their lists against the registry at least every 31 days.⁷

An existing business relationship provides a limited exception. If the consumer made a purchase or completed a transaction, the business can call for up to 18 months from the date of the last purchase, delivery, or payment. If the consumer only made an inquiry or submitted an application without buying, the window is three months.⁸ If a consumer specifically asks to be placed on your company’s internal do-not-call list, that request overrides any existing relationship.

Businesses must maintain a company-specific do-not-call list and keep opt-out records for at least five years. Records must include the person’s name, phone number, the date of the request, and the company on whose behalf the call was made.⁹ Recordkeeping can be delegated to a third-party telemarketer by written agreement, but the seller remains responsible for making sure the telemarketer actually follows through.

Caller Identification Disclosures

Any call using a prerecorded or artificial voice must identify the business or individual responsible for the call at the beginning of the message. A business must provide the name under which it is registered with the relevant state authority. During or after the message, the caller must also provide a callback number, and it cannot be the number of the autodialer itself. The callback number has to reach the business so the recipient can request placement on the do-not-call list.¹⁰

For live telemarketing calls, the caller must provide the name of the individual making the call, the name of the entity on whose behalf the call is made, and a phone number or address for that entity. These disclosures apply to every call, not just the first. When a predictive dialer connects a consumer to a live agent, the agent needs to deliver these disclosures promptly on connection.

Damages and Enforcement

The per-violation math is what makes the TCPA a powerful litigation tool. A person who receives a call or text violating the ATDS or prerecorded-voice restrictions can sue for $500 per violation, meaning per call or per text, or for actual monetary loss, whichever is greater. No proof of actual harm is required to collect the $500. For willful or knowing violations, the court can treble the award up to $1,500 per violation.¹

A separate damages provision covers Do Not Call violations. A person who receives more than one violating call within a 12-month period from the same entity can recover up to $500 per violation, with treble damages available for willful conduct. The Do Not Call provision includes an affirmative defense: a business can avoid liability by proving it established and implemented reasonable practices and procedures to prevent violations.¹

The numbers scale fast. A predictive dialer campaign that contacts 10,000 people without proper consent generates $5 million in potential statutory damages before trebling. Class actions are common in TCPA litigation because every class member’s claim is simple and formulaic: did the defendant call them, did they consent, what technology was used. Individual issues rarely dominate, which makes certification relatively straightforward compared to other class action categories.

Beyond private suits, the FCC can impose forfeiture penalties, and state attorneys general can bring enforcement actions. Many states have enacted their own telemarketing statutes with penalties that stack on top of federal liability, so a single campaign can generate exposure on multiple fronts at once.

Exemptions and the Value of Documented Consent

The TCPA carves out a few categories from its automated-call restrictions. Emergency calls are the broadest exemption; calls necessary for situations affecting health and safety do not require prior consent, regardless of technology.¹ Public safety notifications, utility warnings, and health alerts generally fall under this exemption. For residential landlines, the FCC has exempted prerecorded calls that are non-commercial, that come from tax-exempt nonprofits, or that are commercial without advertising, all capped at three calls per 30-day period to the same number.³ Calls to collect debts owed to or guaranteed by the federal government also get specific statutory treatment, but state and private debts do not.

Valid prior express consent remains the most reliable shield against TCPA liability. If the recipient agreed to the contact and the caller can prove it, the call is lawful even if placed with an ATDS or a prerecorded message. Consent documentation, not just technology classification, is the single most important compliance investment for any business running a predictive dialer operation.
