The short answer
In the US, most business-to-business cold calls are exempt from the National Do Not Call Registry, so you can call a company’s line to sell it something. The exemption has limits: some products are excluded, calls to a person’s cell phone with an AI or prerecorded voice need prior consent, and consumer calls follow stricter rules. Here is what applies.
We make Extra, an AI agent platform, so this article is written by an interested party. Facts about other tools and about the law come from the sources listed at the bottom, as of the date shown.
Can you cold call businesses in the US?
Yes. Most business-to-business telemarketing calls are exempt from the Do Not Call provisions of the FTC’s Telemarketing Sales Rule (TSR), and the National Do Not Call Registry is meant for personal numbers: the FTC says business phone numbers are not covered. So a small business can generally call another company’s line to sell it something relevant.
That freedom has edges. Some B2B calls are not exempt, the TCPA adds its own rules for automated and artificial voices, and many “business” numbers are really a sole owner’s personal cell. A small business that cold calls should know where those lines are, because penalties are per call.
The good news: the rules are short enough to fit on one page, and following them makes calls better, not just safer.
Which B2B calls are not exempt?
Under the TSR, the B2B exemption does not cover calls selling nondurable office or cleaning supplies (paper, toner, ink and the like), and it does not cover calls to employees at work that solicit them for their personal use or for donations, according to the FTC.
| Call | Exempt from TSR Do Not Call rules? | Example |
|---|---|---|
| Selling a business service to a company | Generally yes | Bookkeeping services to a dental office |
| Selling nondurable office or cleaning supplies | No: other TSR rules apply | Toner to a law firm |
| Selling to an employee for personal use | No | A personal insurance policy pitched on a work line |
| Calling a sole owner’s personal cell | Treat it as a consumer call | A contractor’s only phone |
The FCC took a similar line years ago: the registry protects residential subscribers, and calls to businesses are not barred, while home-based businesses are reviewed case by case. In practice, if the number is someone’s personal phone, treat the call as a consumer call.
What must you say when the call starts?
For outbound sales calls covered by the TSR, the caller must promptly disclose, before any pitch, the seller’s identity, that the purpose is to sell, and the nature of the goods or services. It is good practice in every B2B call too: it saves time and builds trust.
- Say who you are and which company you represent.
- Say why you are calling, in one sentence.
- Ask if it is a good time, and respect a no.
- Transmit accurate caller ID; never spoof a number.
- Keep an internal do-not-call list and honor every request to stop calling.
The stakes are real: the FTC lists a civil penalty of $53,088 per violation for TSR breaches such as failing to make required disclosures.
What about calling consumers?
Calling consumers is far more regulated. If a number is on the National Do Not Call Registry and you have no established business relationship or written permission, you cannot make a sales call to it. Calls are limited to between 8 a.m. and 9 p.m. local time for the person called, and company-specific do-not-call requests must be honored.
If your “B2B” list mixes in sole proprietors and freelancers on personal cells, scrub it against the registry or switch to written outreach for those contacts.
Can an AI voice agent make cold calls?
Not without consent in most cases. In February 2024 the FCC ruled that AI-generated voices, including voice clones, are “artificial” voices under the Telephone Consumer Protection Act, so calls using them need the called party’s prior express consent unless an exemption applies.
For a small business, that settles it: an AI agent that dials a list of cell numbers with a synthetic voice to pitch your service is a legal risk. AI is useful around the call instead: researching the account, writing the opening line, summarizing notes afterward, drafting the follow-up email. If you ever use an AI voice with people who agreed to it, have it say it is an AI at the start; honesty is the right default.
How do you prospect better with AI?
For a small business, prospecting that works in 2026 targets specific companies, at the right moment, by email or LinkedIn, with a personal message, and saves the phone for people who answered. AI makes that workable at small scale.
- Start from public signals: a new business filing, a move, a hiring spree, a contract win.
- Pick ten accounts a week, not a thousand: the ones your offer fits right now.
- Find the right person and their work email, without guessing.
- Write a short message that mentions the signal and offers one specific thing.
- Follow up once, then stop. Log every opt-out.
- Call the ones who replied: that is where the phone wins.
Worked example: a commercial cleaning company that writes each week to ten businesses that just moved into its city, mentioning the move, usually books more meetings than a hundred cold calls, without the legal exposure. Test it for a month and count replies.
How does Extra help you prospect within the rules?
Extra (hello-extra.com), the AI agent platform for small businesses, does not make cold calls. Jim, its prospecting agent, ranks target accounts, checks sources and your sending domain, and runs email and LinkedIn campaigns that you approve once, with LinkedIn invitations capped at 20 a day (see Jim). His public-signal feeds today cover French registries, so for US accounts you bring the list. Extra costs $99 per month for all eight agents (pricing).
When Extra is not the right fit: if your business lives on inbound calls from consumers, you need a solid web form with clear consent and time on the phone, not an outbound tool.
Frequently asked questions
Do state laws add rules for B2B calls?
Some states have their own telemarketing laws and registration requirements, and a few reach business calls. Check the states you call into before you scale.
Is cold email treated the same way?
No. Commercial email follows the CAN-SPAM Act: honest headers and subject lines, a physical address and a working opt-out honored promptly.
Can I call a lead who filled out my website form?
Yes, that is an inquiry, and it is the best call you will make all week. Call quickly and keep a record of the request.
Where should you start this week?
- Split your call list into companies and personal numbers.
- Write a three-line call opening with the required disclosures.
- Create an internal do-not-call list.
- Pick ten target companies from a public signal.
- Email them first, then call those who answer.
