TL;DR

  • The TCPA recognizes three operative consent concepts: prior express consent, prior express written consent, and implied consent through an established business relationship. Each one authorizes a different kind of outreach.
  • Prior express consent covers informational, non-telemarketing calls to mobile numbers using regulated technology. It can be given orally or in writing and does not require a specific disclosure script.
  • Prior express written consent is required for any autodialed or prerecorded telemarketing call or text to a mobile number, and for any prerecorded telemarketing call to a residential line. It must satisfy four specific elements set out in 47 C.F.R. § 64.1200(f)(9).
  • Implied consent has narrow application — primarily for calls placed manually within an established business relationship, and even there it is shrinking after the FCC’s one-to-one consent revisions and subsequent rulemakings.
  • Misclassifying which consent type applies is one of the most common mistakes in TCPA litigation. The framework matters more than the form.

Overview: Why the Categories Exist

The Telephone Consumer Protection Act, codified at 47 U.S.C. § 227, is structured around the technology of the call and the purpose of the call. The statute does not regulate human-dialed conversational calls between two private parties. It regulates automated outreach — calls and texts placed using an automatic telephone dialing system, an artificial or prerecorded voice, or a prerecorded message — when that outreach reaches certain protected categories of recipients.

The FCC’s implementing regulations at 47 C.F.R. § 64.1200 fill in what the statute leaves general. Those rules establish two operative consent standards and acknowledge a third doctrinal category — implied consent — that survives in narrow circumstances and through case law.

Knowing which standard applies to a given call is the first analytical step in any TCPA compliance review. The wrong category produces the wrong record, and the wrong record fails in court.

Prior express consent is the baseline standard for any autodialed or prerecorded call to a mobile number that is not telemarketing. The classic examples are appointment reminders, fraud alerts, package delivery notifications, prescription refill reminders, and school closures.

What It Authorizes

Under 47 U.S.C. § 227(b)(1)(A)(iii), autodialed and prerecorded calls to a mobile number are prohibited unless made with the prior express consent of the called party. When the call is purely informational — meaning it does not include any encouragement to purchase or rent property, goods, or services — express consent without the written formalities is sufficient.

The FCC confirmed this distinction most clearly in its 2012 TCPA Order, which split informational from telemarketing communications and applied the heightened written-consent requirement only to the latter.

What It Requires

The consent must be:

  • Prior — given before the call or text is placed, not gathered after the fact.
  • Express — an affirmative statement or action, not silence or inactivity. Providing a phone number to a caller has been treated by many courts as express consent to be contacted at that number for the transaction in which it was provided. The Eleventh Circuit’s decision in Murphy v. DCI Biologicals Orlando, LLC (11th Cir. 2015) is the canonical authority for this point, though courts continue to debate the boundaries.
  • From the called party — meaning the current subscriber or customary user of the number, not whoever happened to provide the number. Reassigned-number cases are litigated under this element.

Express consent can be oral, written, or electronic. It does not require a specific disclosure script. It does, however, require a record. A caller who cannot reconstruct when and how the consumer consented bears the same evidentiary burden as one whose record is generic or contradicted.

Where It Breaks Down

Two recurring failure modes appear in the case law. The first is scope creep — using a number provided for one purpose (for example, account servicing) to deliver a different category of message (for example, a marketing offer). Once the message becomes telemarketing, express consent is no longer enough. The second is attribution failure — calling a number that has been reassigned, where the original consenter no longer holds the line. The FCC’s 2023 Reassigned Numbers Database rules created a limited safe harbor here for callers who query the database in good faith.

Prior express written consent is the strictest TCPA standard and the one that governs the lead generation industry. It applies whenever an autodialed or prerecorded telemarketing call or text reaches a mobile number, and whenever a prerecorded telemarketing call reaches a residential landline.

What It Authorizes

The FCC’s rules at 47 C.F.R. § 64.1200(a)(2) and (a)(3) require prior express written consent for:

  • Telemarketing calls placed to wireless numbers using an autodialer or prerecorded or artificial voice.
  • Telemarketing texts sent to wireless numbers using an autodialer.
  • Prerecorded telemarketing calls placed to residential lines (subject to limited exemptions).

A call is “telemarketing” under 47 C.F.R. § 64.1200(f)(13) if its purpose is to encourage the purchase or rental of, or investment in, property, goods, or services. The definition is broad. Calls that mix informational and promotional content are generally treated as telemarketing if any portion is promotional.

What It Requires

47 C.F.R. § 64.1200(f)(9) sets out four mandatory elements. The agreement must:

  • Be in writing. Under the E-SIGN Act (15 U.S.C. § 7001), an electronic signature — a checkbox, a typed name, or a documented clickwrap action — satisfies this requirement.
  • Bear the signature of the consumer. The signature must be attributable to the specific consumer being called, not merely to the household or to the publisher of the form.
  • Include a clear and conspicuous disclosure that the consumer authorizes the seller to deliver telemarketing calls or texts using an automatic telephone dialing system or prerecorded or artificial voice.
  • Make clear that consent is not a condition of purchase. A consumer cannot be required to agree to telemarketing as a prerequisite to obtaining the underlying good or service.

The FCC has further interpreted these requirements through a series of declaratory rulings, the most consequential of which is the 2023 Lead Generators Order (CG Docket No. 02-278) and its subsequent revisions. The current rule, as in effect after the FCC’s 2025 reconsideration proceedings, requires consent to be given to one seller at a time — the “one-to-one consent” rule — and requires the disclosure to identify the seller by name and describe the goods or services being offered.

How Courts Treat It

Courts have been consistent that the four elements are not optional and that a missing or defective element will void the consent. Van Patten v. Vertical Fitness Group, LLC (9th Cir. 2017) emphasized that consent must be commensurate with the scope of the messaging it authorizes — a consumer who agrees to receive gym membership offers has not consented to receive offers from a credit card affiliate. Reyes v. Lincoln Automotive Financial Services (2d Cir. 2017) explored the limits of revocation, holding that consent provided as part of a binding contract cannot be unilaterally revoked, though that holding has been narrowly applied to other facts.

The recurring failure modes in written-consent cases are familiar:

  • Generic seller language. “Marketing partners” or “third-party affiliates” without a specific named seller is one of the most reliable ways to lose a TCPA case.
  • No record of what the consumer saw. The bare form, retained in the abstract, is not enough; courts want to see what the consumer actually viewed and interacted with at the moment of consent.
  • No proof the consumer signed. A checkbox state without a contemporaneous record of the click — IP address, timestamp, user agent, session identifier — invites the plaintiff’s argument that the form was never actually completed by the named consumer.

Implied consent under the TCPA is a narrower doctrine than many practitioners assume. Its main residual application is to manually-dialed live calls placed within an established business relationship (EBR) — a transactional relationship that arose within the preceding eighteen months, or an inquiry made within the preceding three months, under the FCC’s traditional EBR rules at 47 C.F.R. § 64.1200(f)(5).

What It Authorizes

For manually-dialed telemarketing calls to a residential landline within an EBR, the FCC has historically permitted calls without separate written consent. The EBR exemption does not extend to:

  • Autodialed or prerecorded telemarketing calls to mobile numbers — those always require prior express written consent.
  • Prerecorded telemarketing calls to residential lines — those generally require prior express written consent, subject to limited exemptions.
  • Calls to numbers on the National Do Not Call Registry, except where the EBR exemption applies and the consumer has not opted out of the specific company’s calls.

Where It Survives in Mobile and Text

In the mobile and text context, “implied consent” has very limited play. Courts have occasionally found implied consent where a consumer provided a phone number in the course of a specific transaction and the resulting communications were directly related to that transaction. This is the Murphy line of reasoning, and it is best understood as a flavor of express consent rather than as a true implied-consent doctrine. Outside that narrow channel, callers who rely on inferred consent for autodialed mobile communications consistently lose.

Telemarketing vs. Informational: The Most Important Line in TCPA Practice

Because the consent standard turns on whether a communication is telemarketing, the classification of the call drives the entire compliance posture. A few principles consistently emerge from FCC guidance and case law:

  • Purpose, not phrasing, controls. A “courtesy” call that mentions a promotion is telemarketing if any part of its purpose is to encourage a purchase. The FCC’s Soundbite Order (2012) and successor rulings emphasize this functional test.
  • Mixed content tips toward telemarketing. Where a single message combines an informational element with a promotional element, the FCC has historically treated the message as telemarketing in its entirety.
  • The recipient’s perception is relevant but not dispositive. Courts will look at what a reasonable consumer would understand the message to be, but they will also examine the caller’s internal documentation about the campaign’s purpose.

Misclassifying a campaign as informational when it is in fact telemarketing is a structural error that no amount of record-keeping will fix. The wrong consent type produces a record that proves the wrong thing.

Use this sequence to determine which consent standard applies to a given call or message:

  • Is the recipient a mobile number? If yes, mobile rules apply for any autodialed or prerecorded contact.
  • Is the technology autodialed, prerecorded, or artificial-voice? If yes, the TCPA’s consent requirements are in play regardless of medium.
  • Is the purpose of the call telemarketing as defined by 47 C.F.R. § 64.1200(f)(13)? If yes, prior express written consent is required. If no, prior express consent is sufficient.
  • Is the message a text? Texts to mobile numbers using an autodialer follow the same rules as autodialed mobile calls. Telemarketing texts require prior express written consent.
  • Does the consent extend to this specific seller? Generic affiliate or partner disclosures will not satisfy the seller-identification requirement under current FCC rules.
  • Was the consent given before the call? Consent obtained after a call has been placed cannot retroactively cure the violation that the original call created.

The record needs to match the standard. A useful default is to capture, for every consenting consumer:

  • The disclosure text exactly as it was rendered to the consumer, not a stored template that may have changed since.
  • The seller named in the disclosure, with a record that the consumer was shown that specific seller at the moment of consent.
  • The consumer’s affirmative action — a clickwrap submission, an unchecked-by-default checkbox interaction, a typed name with date — recorded in a way that ties it to the specific consumer and the specific session.
  • A contemporaneous timestamp anchored to a reliable time source, not just the database write time.
  • A chain of custody from the consent event to the phone number ultimately dialed, sufficient to rebut a claim that the lead was acquired from an unrelated source.
  • A revocation channel that respects the consumer’s right to withdraw consent and documents the withdrawal.

The depth of documentation should scale with the consent type. Informational express consent can be lighter on disclosure language but still needs proof of the consumer’s affirmative provision of the number. Express written consent needs the full record because the four elements are not optional and the burden is on the caller.

Key Takeaways

  • The TCPA’s consent framework has three categories — prior express consent, prior express written consent, and implied consent through an established business relationship — and each authorizes a different scope of contact.
  • Prior express written consent is the strictest standard and the one that governs autodialed and prerecorded telemarketing to mobile numbers. Its four elements at 47 C.F.R. § 64.1200(f)(9) are mandatory, and courts will void consent that misses any of them.
  • Implied consent has narrow application after the FCC’s recent rulemakings; it does not authorize autodialed mobile telemarketing under any reading of the current rules.
  • The distinction between informational and telemarketing communications controls which consent standard applies. The functional purpose of the call, not its phrasing, drives the classification.
  • The right consent standard is necessary but not sufficient. Documenting the consent — what the consumer saw, what they did, when they did it, and how the resulting number connects to the call — is what wins or loses TCPA cases.

A defensible TCPA program starts with classifying every outbound campaign by consent type and then engineering the record to match. The categories are not interchangeable; neither are the records they require.

If you are mapping consent obligations across multiple campaigns or evaluating whether your current records will hold up in litigation, the path forward is the same: capture the consumer’s experience at the moment of consent, in a form that an unrelated party can reproduce and an indifferent court can credit.
