Telemarketing caller ID requirements: what US sales calls must show

US telemarketing caller ID requirements come down to three rules. Every sales call must transmit caller ID and never block it. The number shown must let anyone make a do-not-call request during business hours. And the caller ID must never be used to mislead with intent to defraud or cause harm. The FCC’s version of these rules applies to B2B calls too.

The FCC rule: transmit, don’t block, and be reachable

The core rule is 47 CFR 64.1601(e). Any person or entity that engages in telemarketing must transmit caller ID information, and:

1. The caller ID must include a number: the calling party number or the billing number, plus the telemarketer’s name when the carrier makes it available.
2. The seller’s details can replace the caller’s. It is not a violation to show the name of the seller the call is made for, and the seller’s customer service number.
3. The number must work for opt-outs. It “must permit any individual to make a do-not-call request during regular business hours.”
4. No blocking. Anyone engaged in telemarketing is prohibited from blocking caller ID. Tax-exempt nonprofits are exempt from this paragraph.

The FCC defines telemarketing in 47 CFR 64.1200(f) as a call made to encourage the purchase or rental of, or investment in, property, goods or services, “transmitted to any person.” Nothing in it limits the rule to consumers.

The B2B myth, checked

“Caller ID rules don’t apply to B2B calls” is half right, which makes it dangerous.

The FTC’s Telemarketing Sales Rule has its own caller ID requirement at 16 CFR 310.4(a)(8). It reads much like the FCC’s: transmit the number, and the name when the carrier provides it, or substitute the seller’s customer service number that is answered during regular business hours. But 16 CFR 310.6(b)(7) exempts most calls between a telemarketer and a business. Only the misrepresentation rules in 310.3(a)(2) and (4), and calls selling nondurable office or cleaning supplies, stay in scope.

The FCC’s rule has no business-to-business exemption. An SDR calling an IT director’s mobile phone about software is making a telemarketing call under 64.1601(e). So the safe reading for B2B teams is simple: follow the FCC rule on every sales call.

Which number should you show?

Option	Allowed?	Watch out for
The rep’s direct number	Yes	Calls back must reach someone, or a voicemail that takes opt-outs, during business hours
A local number your company holds	Yes	Same callback test. See local presence dialing
The seller’s customer service number	Yes, explicitly	The service team must know how to take a do-not-call request
A number you don’t hold, or a random one	Risky	Misleading caller ID used with intent to defraud or cause harm is illegal
Blocked or “No caller ID”	No	Prohibited for telemarketing

The fourth row is where 47 CFR 64.1604 comes in. It bans knowingly causing caller ID to show “misleading or inaccurate” information “with the intent to defraud, cause harm, or wrongfully obtain anything of value.” It also covers callers outside the US when the person called is in the US. A sales team showing numbers it doesn’t hold, which ring a stranger on callback, is inviting that question. It is also a fast way to earn spam labels, as our guide to Spam Likely labels explains.

What the rep must say once the call connects

Caller ID is what shows before the answer. Once someone picks up, 47 CFR 64.1200(d)(4) asks more of telemarketing calls to residential subscribers. The caller must give:

• the name of the individual caller;
• the name of the person or entity on whose behalf the call is made;
• a telephone number or address where that entity can be contacted.

The number can’t be a 900 number or one that charges more than local or long-distance rates. A plain opener covers it: “Hi, this is Priya Shah from Northwind Logistics. We’re at 512-555-0142.” Name, company, number, then the reason for the call.

A caller ID checklist to copy

Run this before a new campaign or a new block of numbers goes live:

1. Caller ID is on for every line and every dialing mode. No line sends “Private” or “Unknown.”
2. Every number is one you hold or the seller’s customer service number.
3. Call each number back from an outside phone. It must reach a person or a voicemail during business hours.
4. The voicemail mentions opt-outs. “To stop calls from us, leave your number and say remove.”
5. Opt-outs reach your do-not-call list. Residential requests must be honored within 10 business days under 64.1200(d)(3).
6. The caller name is registered, so the display reads your company, not a city. See CNAM registration for business.
7. Calls are signed. Check your STIR/SHAKEN attestation level with your provider.
8. Openers name the rep, the company and a number on every call.

A sales floor with 12 reps and 36 local numbers can finish step 3 in an afternoon. It is the step most teams skip.

How DialSavvy handles this

DialSavvy is the carrier for the numbers you call from. Each workspace’s numbers are its own, and DialSavvy files the registrations: business profile, SHAKEN/STIR, caller name and caller-ID registrations. Local caller ID shows a number your workspace holds, so a callback reaches your team. Each number makes up to 50 calls a day. Spam protection and number health are coming.
