Compliance

TCPA compliance for outbound calling: the practical guide

  • 7 min read

By Last updated

The short answer

The TCPA governs US telemarketing calls, automated dialing, pre-recorded messages, and texts. Marketing calls to mobiles using automated technology require prior express written consent, calls are limited to 8am–9pm in the called party's local time, and damages run $500 to $1,500 per call with no cap.

This is a practitioner's summary, not legal advice

The TCPA is litigated constantly and interpretations move. Use this to understand the shape of the obligations and to ask your counsel better questions, not as a substitute for asking them.

The Telephone Consumer Protection Act is unusual among regulations in that it is enforced mostly by private plaintiffs rather than by a regulator. Damages are statutory, per call, and uncapped, which means a modest campaign against the wrong list produces exposure that dwarfs the revenue it was meant to generate. That structure is why TCPA compliance is an engineering problem, not a policy document.

FCC safe-harbour ceiling on abandoned calls

Almost every TCPA claim turns on consent. The standard depends on what you are calling, how you are calling it, and why.

Which consent standard applies
What you are doingConsent needed
Marketing call or text to a mobile, using automated dialing or a pre-recorded voicePrior express written consent
Marketing call to a residential landline with a pre-recorded voicePrior express written consent
Informational or transactional call to a mobile (appointment reminder, delivery notice)Prior express consent: lower bar, often satisfied by the customer giving you the number
Manually dialed marketing call to a number not on any DNC listNo TCPA consent required, but DNC and calling-hour rules still apply

What “prior express written consent” actually requires

Four things, all of which have to be true simultaneously:

  1. A clear and conspicuous disclosure that the person will receive marketing calls or texts, that they may be automated or pre-recorded, and that consent is not a condition of purchase.
  2. An affirmative act by the consumer: a ticked box they ticked, a signature, a keyed reply. Pre-ticked boxes fail. Consent buried in terms of service fails.
  3. Identification of the specific seller the consent is given to. Consent given to a lead aggregator does not automatically extend to whoever buys the lead.
  4. A record you can produce years later: the exact language shown, the timestamp, the channel or IP, and the specific phone number consented to.

The burden of proof is yours

In a TCPA dispute you must prove consent existed. The plaintiff does not have to prove it did not. That asymmetry is why what you store matters as much as what you collect: consent you cannot evidence is, functionally, consent you do not have.

Consent obtained through a lead vendor is only as strong as the record the vendor can produce on demand. If your contract does not require them to hand over the disclosure text, timestamp, and IP for any lead you call, you are buying exposure alongside the lead.

Do Not Call: two lists, both binding

The national registry and your own internal list are separate obligations and both apply.

  • The national registry must be scrubbed against on a regular cycle. Treat it as a pre-dial gate, not a post-campaign report; a scrub that happens after the calls is an audit finding, not a control.
  • Your internal list records anyone who has asked you specifically to stop. Requests must be honoured promptly and kept indefinitely, and an internal request overrides an existing business relationship and any prior consent.

The internal list is where teams most often fail, because the request usually arrives verbally, mid-call, and has to survive the rep's memory. It should be a single keystroke in the dialer that suppresses the number across every campaign immediately. See call disposition codes for how that gets wired into the workflow.

Calling hours, and why area code is the wrong input

The federal window is 8am to 9pm in the called party's local time. Several states narrow it further, and some restrict Sundays and holidays.

The trap is deriving the time zone from the area code. Number portability means people keep their mobile number when they move: a 212 number may sit in California and a 415 number in Texas. Any system that infers the calling window from the area code alone will call outside the window for a meaningful slice of every list, and each of those is an independent violation.

The workable approach is to use the best location data you actually hold (billing address or stated location), fall back to area code only when you have nothing better, and be conservative at the boundaries. Nine in the morning Eastern is safe everywhere in the continental US; eight is not.

Abandoned calls and the 3% safe harbour

This is the rule that constrains predictive dialing, and it is widely misunderstood.

An abandoned call is one a live person answers where no agent is connected within two seconds of their greeting. The FCC safe harbour caps these at 3% of calls answered by a live person, measured over each successive 30-day campaign period.

The denominator is live answers, not dials

Counting every dial in the denominator makes a non-compliant campaign look compliant by a wide margin. 1,000 live answers with 42 drops is 4.2% (over the line) even though it might be a fraction of a percent of total dials.

The safe harbour also requires that when no agent is available you play a recorded message identifying the caller and the purpose, within two seconds of the greeting, and that you retain records demonstrating compliance. Staying silent does not avoid the classification; it just makes the call worse.

The practical consequence: pacing must be governed by the system against a hard ceiling, not watched on a dashboard. A power dialer sidesteps the rule entirely because one call per agent means an agent is always waiting.

Revocation

Consumers can revoke consent at any time and by any reasonable means: a reply of STOP, a verbal request on a call, an email, a letter. You cannot require a specific channel or form, and you cannot make revocation harder than granting consent was.

Operationally, that means every channel through which a person might say stop needs to write to the same suppression list, and it needs to apply across campaigns rather than only to the one they were called from.

What a defensible setup looks like

  1. 1

    Capture consent with its evidence

    Store the exact disclosure text shown, the timestamp, the channel or IP, the specific number, and the named seller. A consent record without its language is not evidence.
  2. 2

    Gate dialing on the record

    A contact with no consent basis for the campaign type is not dialed. This has to be enforced in the system; a policy that relies on a rep checking will fail at volume.
  3. 3

    Scrub before every campaign

    National registry and internal list, as a pre-dial gate. Log what was suppressed and why.
  4. 4

    Enforce calling hours per contact

    In the contact's own time zone, derived from the best data you hold, with campaigns held rather than dialed when the window is closed.
  5. 5

    Cap abandonment in the pacing engine

    Measured against live answers, with automatic throttling as the rate approaches the ceiling, and the identification message playing when no agent is free.
  6. 6

    Keep the records

    Consent, suppression, calling-hour decisions, abandonment rates, and recordings, retained long enough to answer a claim that arrives years later.

The uncomfortable summary

Almost every serious TCPA loss traces to the same root cause: a control that existed as a rule people were supposed to follow rather than as behaviour the system enforced. Reps forget, lists get loaded from the wrong file, a campaign starts an hour early, a stop request never leaves someone's notebook.

Put the controls in the dialer and the compliance question becomes boring, which is exactly what you want it to be.

Frequently asked questions

What is prior express written consent under the TCPA?
A clear, conspicuous disclosure that the person will receive marketing calls or texts that may be automated, an affirmative act by them agreeing to it, identification of the specific seller, and a stored record of the exact language, timestamp, channel, and number. Pre-ticked boxes and consent buried in terms of service do not satisfy it.
What hours can I legally make telemarketing calls?
8am to 9pm in the called party's local time zone under federal rules, with several states imposing narrower windows on top. Because number portability makes area code an unreliable guide to where someone actually is, the calling window should be derived from the best location data you hold and enforced by the dialer.
How is the 3% abandonment rate calculated?
Abandoned calls divided by calls answered by a live person, measured over each successive 30-day campaign period. The denominator is live answers, not total dials; using total dials makes a non-compliant campaign look compliant by an order of magnitude.
Does the TCPA apply to text messages?
Yes. Texts are treated as calls for TCPA purposes, so marketing texts to mobiles need prior express written consent, and STOP requests must be honoured promptly and permanently. Carrier-level A2P 10DLC registration is a separate, additional requirement for delivery.
Can a customer revoke consent verbally?
Yes. Consent can be revoked at any time by any reasonable means, including verbally mid-call. You cannot require a particular channel or form, which means every route through which someone might say stop has to write to the same suppression list, applying across all campaigns.
Does manual dialing avoid the TCPA?
It avoids the consent requirements tied to automated dialing technology, but not the rest. Do Not Call obligations, calling-hour limits, and revocation all still apply to manually dialed marketing calls.

See it working: predictive dialer

A predictive dialer calls ahead of your agents, using live answer rates and call durations to forecast when an agent will next be free. It keeps agents talking for most of the hour instead of waiting, and it is the highest-throughput dialling mode available to a contact centre.
