Yes. B2B cold calling is legal in the United States and Canada. A rep can dial a business number and ask a decision-maker to talk. Neither country has banned that, and neither requires a business to opt in before a seller may call it.
What the law regulates is how you call: autodialers and recorded or AI voices to cell phones in the US, calling hours and caller identification in Canada, call recording in eleven US states, and the email or text you send afterward.
We run outbound from Pakistan for US and Canadian clients, so this comes up on most discovery calls. What follows comes from the primary sources. Treat it as a practitioner’s summary and have counsel check anything you rely on.
United States: what the TCPA restricts
The Telephone Consumer Protection Act (TCPA), enforced by the FCC, is the law people mean when they ask whether cold calling is illegal. Its core prohibition turns on the dialing technology, whoever picks up.
No one may initiate a telemarketing call using an automatic telephone dialing system or an artificial or prerecorded voice to a cell phone number without the “prior express written consent of the called party,” defined as a signed agreement naming the seller and the number (Cornell LII, verified October 14, 2026, law.cornell.edu).
That is why manual dialing matters. A rep who dials by hand is outside the autodialer definition, and a live voice is a live voice. The consent problem belongs to teams that blast cell numbers with power dialers, ringless voicemail or recorded pitches.
The FTC’s Telemarketing Sales Rule and the B2B exemption
The Telemarketing Sales Rule (TSR), enforced by the FTC, is the rule behind the National Do Not Call Registry, and it has exempted most business calls since 1995 (Federal Register, verified October 14, 2026, govinfo.gov). The exemption sits in 16 CFR 310.6(b)(7). “Telephone calls between a telemarketer and any business to induce the purchase of goods or services or a charitable contribution by the business” are outside the Rule, with one carve-out for “calls to induce the retail sale of nondurable office or cleaning supplies” (eCFR, verified October 14, 2026, ecfr.gov).
That settles the Do Not Call question. Even the office and cleaning supply carve-out leaves those sellers outside the Registry provision, 310.4(b)(1)(iii)(B); the rest of the Rule applies to them. The words “by the business” matter. A pitch to an employee on a business line for something personal is a purchase by a person, and we would not rely on the exemption for it.
The exemption narrowed in 2024. The FTC’s final rule, published April 16, 2024 (89 FR 26760) and effective May 16, 2024, extended the TSR’s ban on material misrepresentations to B2B telemarketing. The FTC wrote that the amendment “refrains from imposing any burdens on B2B sellers and telemarketers, including recordkeeping requirements” (Federal Register, verified October 14, 2026, govinfo.gov). The codified exemption now excludes the misrepresentation provisions, 310.3(a)(2) and (a)(4) (Cornell LII, verified October 14, 2026, law.cornell.edu).
A B2B caller can skip the registry scrub. It still cannot misstate who it is or what it sells. Several states keep their own do-not-call lists and telemarketing statutes, some with no business carve-out, so we treat state rules as part of campaign setup.
If you would rather hand this to a team that does it every day, see our B2B cold calling services for US and Canadian teams: a dedicated SDR at $1,800/month for 40 hours a week, or a pay-as-you-go job from $399, with every list scrubbed against the US registry and Canada’s DNCL before the first dial.
Call recording and AI voices
Recording law applies whether or not the call is B2B. Federal law and most states need one party’s consent, which can be the rep’s. Eleven states required everyone’s consent as of the chart’s date: California, Delaware, Florida, Illinois, Maryland, Massachusetts, Montana, Nevada, New Hampshire, Pennsylvania and Washington, per a 50-state chart by the law firm Matthiesen, Wickert & Lehrer (chart dated January 13, 2022, Wayback Machine copy archived January 16, 2022, verified October 14, 2026, mwl-law.com via web.archive.org). Announce the recording whenever either end of the call is in an all-party state, and confirm the current list before each campaign; that chart is over four years old.
“AI SDR” tools that call with a synthetic voice are not a loophole. In Declaratory Ruling FCC 24-17, adopted February 2 and released February 8, 2024, the FCC confirmed that the TCPA’s restrictions on an “artificial or prerecorded voice” encompass current AI technologies that generate human voices, so such calls need prior express consent absent an emergency or exemption; 26 state attorneys general filed comments in support (FCC, Wayback Machine copies, verified October 14, 2026, docs.fcc.gov via web.archive.org and fcc.gov via web.archive.org).

Canada: the DNCL exemption is narrower than it sounds
The CRTC’s Unsolicited Telecommunications Rules have three parts: the National Do Not Call List (DNCL) Rules, the Telemarketing Rules and the Automatic Dialing-Announcing Device (ADAD) Rules. Business calls are exempt from the first part only.
The DNCL operator states that “The National DNCL Rules do not apply to a telemarketing telecommunication made to a business consumer,” and that business numbers, including personal lines also used for business, are not to be registered (National DNCL operator, verified October 14, 2026, lnnte-dncl.gc.ca).
Three obligations survive, per the operator’s telemarketer FAQ (National DNCL operator, verified October 14, 2026, lnnte-dncl.gc.ca):
- Organizations on whose behalf telemarketing is conducted must register with the DNCL operator “even if the calls you make directly, or that are made on your behalf are exempted.” A paid subscription is needed only for non-exempt calls.
- The Telemarketing Rules still apply “regardless of whether they are making calls that are specifically exempted from the National DNCL Rules.”
- Asked whether the rules extend to telemarketers outside Canada, the operator answers “Yes. The Rules apply regardless of where the call originates.”
The Telemarketing Rules set the limits. Calls are restricted to 9:00 a.m. to 9:30 p.m. on weekdays and 10:00 a.m. to 6:00 p.m. on weekends in the called party’s time zone, subject to tighter provincial hours, and the caller must display the originating number or one where it can be reached (CRTC rules, Wayback Machine copy archived October 1, 2026, verified October 14, 2026, crtc.gc.ca via web.archive.org). Every telemarketer must also name the organization it calls for at the start of the call and keep an internal do-not-call list, adding a name within 14 days and keeping it three years (National DNCL operator, verified October 14, 2026, lnnte-dncl.gc.ca).
The burden of proving a call was B2B sits with the caller. In Telecom Decision CRTC 2010-626 the CRTC upheld a $10,000 penalty against a fax telemarketer that claimed it only sent business-to-business messages, noting that “it is the telemarketer’s responsibility to ensure that the recipients of the telecommunications are businesses and not consumers registered on the National DNCL or health care facilities” (CRTC, Wayback Machine copy archived March 6, 2026, verified October 14, 2026, crtc.gc.ca via web.archive.org).
Canada: CASL governs the follow-up email or text
Canada’s Anti-Spam Legislation does not cover the call. The CRTC’s CASL FAQ says the law applies to commercial electronic messages sent to an electronic address, including SMS, and “does not apply to unsolicited telecommunications, including live voice and automated telemarketing calls” (CRTC, Wayback Machine copy archived October 10, 2026, verified October 14, 2026, crtc.gc.ca via web.archive.org).
The follow-up email is where CASL bites. Section 6 prohibits sending a commercial electronic message unless the recipient has consented, express or implied, and the message identifies the sender, gives contact information and includes an unsubscribe mechanism (Justice Laws Canada, verified October 14, 2026, laws-lois.justice.gc.ca). The CRTC FAQ adds that senders in another country must comply. Ask for the email on the call, then send the follow-up with the sender identified and an unsubscribe link. Our Canadian follow-ups are written to CASL; if you need the consent documented on the delivery file, ask us before the job starts.
US versus Canada at a glance
| Question | United States | Canada |
|---|---|---|
| Scrub B2B calls against the national list? | Not required (TSR B2B exemption) | No scrub required; the client must still register with the DNCL operator |
| Calling hours | 8 a.m. to 9 p.m. for residential lines, some states tighter (47 CFR 64.1200(c)(1), Cornell LII, verified October 14, 2026, law.cornell.edu) | 9:00 a.m. to 9:30 p.m. weekdays, 10:00 a.m. to 6:00 p.m. weekends, called party’s time zone |
| Follow-up email or SMS | TCPA consent for autodialed texts to cells | CASL: consent, identification, unsubscribe |
| Who is responsible | Seller and telemarketer | Telemarketer and client of the telemarketer |
Who is liable when you outsource, and what we do
Both regimes name two parties. The TSR binds the seller and the telemarketer; the CRTC rules bind the telemarketer and the client of a telemarketer, and require the client to make all reasonable efforts to ensure its telemarketer does not call DNCL numbers, internal do-not-call numbers, or emergency and healthcare lines. Hiring an agency, including one outside the country, puts a second accountable party on the call and leaves your name on it.
No vendor can honestly promise it is “compliant,” so ask what it does instead. Our process:
- Humans dial by hand in the prospect’s business hours. Our SDRs sit in Pakistan and work US time zones, with evenings and weekends available. No autodialer, no prerecorded message. Two attempts per lead, a third only if you ask.
- You supply or approve the list. We dedupe it and scrub it against the US National Do Not Call Registry and Canada’s DNCL before a job starts, even where the B2B exemption applies, because mixed lists are how B2B callers get fined (Munzai, verified October 14, 2026, munzaisolutions.com).
- The rep opens with their own name and your company’s name, from a local number we provision or from yours with forwarding. Anyone who asks not to be called again is taken off immediately.
- Calls are recorded where state law allows, kept for 90 days and yours on request. Raise all-party consent states at kickoff and we will plan the opener together.
- You register your organization with the DNCL operator before we dial Canada. The same-day follow-up email to every answered call is written to CASL for Canadian prospects.
Data handling is in our privacy policy. For what the calls look like once compliance is handled, see our guide to B2B cold calling and our cold calling strategies.
A compliance checklist for any calling vendor
- How are calls placed: manual, power dialer, predictive dialer or AI voice? If not manual, what consent do you hold for cell numbers?
- Who supplies the list, and what is it scrubbed against before dialing? Expect the US registry, Canada’s DNCL and your own suppression list by name.
- How do you confirm Canadian numbers are business numbers, and is our organization registered with the DNCL operator before the campaign starts?
- Which calling hours do you enforce, in whose time zone, and what does the opener say?
- How is a do-not-call request logged, and does the follow-up email identify us, include an unsubscribe, and record the consent obtained on the call?
- Will you share recordings and dispositions so we can audit the above?
FAQ
Does the TCPA apply to B2B calls?
Yes, where the method is restricted. The TCPA’s consent rules turn on the dialing technology and the number type. An autodialed or AI-voice marketing call to a cell phone needs prior express written consent whoever owns the number; a live, manually dialed call does not.
Is it illegal to cold call companies in the USA?
No. The Telemarketing Sales Rule exempts calls made to a business to induce a purchase by that business; the one carve-out, nondurable office or cleaning supplies, brings those callers under the rest of the Rule while leaving them outside the Registry provision. Since May 2024 its ban on misrepresentations applies to B2B calls too, and state statutes are a separate layer.
Is cold calling legal in Canada for B2B?
Yes. The National DNCL Rules do not apply to calls made to a business consumer. The Telemarketing Rules still do: identify yourself, display a reachable number, respect the calling windows, keep an internal do-not-call list, and register the client with the DNCL operator. The telemarketer must be able to show the numbers it called were business numbers.
Is AI cold calling legal?
Not without consent in the US. The FCC’s February 2024 ruling confirmed that AI-generated voices are “artificial” voices under the TCPA, so an AI-placed marketing call to a cell phone needs prior express written consent. Manually dialed human calls do not.
Is cold texting legal?
Treat it as the highest-risk channel in both countries. In the US, FCC rules ban autodialed texts to mobile phones without prior consent. In Canada, a commercial SMS falls under CASL and needs consent, identification and an unsubscribe mechanism. Texting is not in our packages; if you want it, ask us and expect a consent conversation first. None of this is legal advice, so confirm the current rules with counsel.
