Telemarketing Sales Rule

TSR / 16 CFR 310 / calling hours / sales call disclosures

In short

The Telemarketing Sales Rule is the FTC rule governing sales calls. Beyond the do not call list, it sets what a caller must say and when they may call: residential calls only between 8am and 9pm local time, and a prompt disclosure that the purpose of the call is to sell something.

Most people know this rule only through the do not call list, which is one part of it. The rest governs the call itself: when it may happen, what must be said, and what counts as deceptive. Those provisions apply whether or not the number was ever on a list.

Start with the clock, because it is the easiest to get wrong. Without the prior consent of the person, calling a residence outside 8am to 9pm is an abusive practice under the rule. The detail that catches businesses is which clock counts: the rule says local time at the called person's location. A team dialing a list across time zones from one office is working to several windows at once.

Then what has to be said, and how fast. The rule requires a telemarketer to disclose truthfully, promptly, and in a clear and conspicuous manner, four things: the identity of the seller, that the purpose of the call is to sell goods or services, the nature of those goods or services, and, where a prize promotion is involved, that no purchase or payment is necessary to win or to increase the chance of winning.

Separately, before a customer agrees to pay, the rule requires clear disclosure of material information. That includes the total costs to purchase, receive or use the goods or services and the quantity involved, all material restrictions, limitations or conditions, and if the seller does not make refunds, a statement saying so.

One more definition closes the obvious loophole. The FTC says that when disclosures are oral, clear and conspicuous means at an understandable speed and pace, and in the same language, tone and volume as the sales offer, so that ordinary consumers can easily hear and understand it. The fast quiet disclaimer at the end is not a disclosure.

In practice

The word doing the most work is promptly, and the FTC defines it rather than leaving it to judgment: for purposes of the rule, promptly means before any sales pitch is given. So a script that opens with rapport, asks how the day is going, and reaches who is calling and why in the second minute has already missed it. Sales training generally teaches the opposite order.

Not the same as

The do not call registry
That governs whether you may call a number at all. This governs how the call is conducted once permitted.
The ban on prerecorded calls
A separate provision about automated voice. These duties apply to a live person too.

Why it matters to you

Outbound calling processes are usually built by sales people from scripts, and the rule specifies script content: what to say, in what order, and how soon. The language it uses is worth noticing too. Violations are not described as bad practice. The rule calls them abusive or deceptive acts and practices, which is the vocabulary of enforcement rather than of guidance.

What to ask or check

  1. 01Does our script state who is selling and that the call is a sales call, near the start?
  2. 02Are we calling to the customer's local time window, not ours?
  3. 03Where a price is discussed, do we disclose total cost, conditions and the refund policy before anyone agrees to pay?

What people get wrong

That the rule is only the do not call list. It also fixes calling hours in the customer's local time and specifies what must be disclosed, promptly, on a live sales call.

Red flags

  • A dialing schedule set to the office time zone rather than the customer's.
  • A script that reaches the purpose of the call after the rapport building.
  • Pricing discussed without total cost, conditions and refund policy disclosed first.

Who owns it

The seller and the telemarketer both. Outsourcing the dialing does not move the rule off the business whose goods are being sold.

Where you will see it

In outbound calling scripts, dialer schedules, and any proposal to call leads on your behalf.

National Do Not Call Registry

The National Do Not Call Registry is the federal list of numbers telemarketers may not call. Sellers subscribe by area code, and FTC guidance says call lists must be scrubbed against it at least every 31 days. Business to business calls are largely outside the rule, with narrow exceptions.

Robocall

A robocall is an outbound call that plays a recorded message. The Telemarketing Sales Rule prohibits placing one to sell something unless the person gave express agreement in writing beforehand. The rule covers calls you place. A system that answers calls coming in to you is a different thing.

AI voice calls

An AI voice call uses a synthesized or cloned voice to speak to the person who answers. In February 2024 the FCC confirmed those voices fall under the existing rules on artificial or prerecorded voice, so the same consent requirements apply. The message must also identify your business and offer an automated way to opt out.

Call tracking

Call tracking replaces the phone number shown to a visitor with a substitute number that routes to your real one. Only calls dialed through that substitute are measured. Google assigns a forwarding number when call reporting is on, and Microsoft requires an ad group to have reached 10 clicks and 10 dollars of spend in 30 days.

STIR/SHAKEN

STIR/SHAKEN is how phone carriers sign outbound calls so the receiving network can tell the caller ID was not faked. The signature is your provider attesting to the accuracy of the number it is sending. Congress required it on internet protocol networks and asked only for reasonable measures elsewhere.

Caller ID spoofing

Caller ID spoofing is sending a number other than the line you are calling from. The federal prohibition is not about the technique. It applies to transmitting misleading or inaccurate caller identification information with the intent to defraud, cause harm, or wrongfully obtain anything of value.
