Quick Answer: Public business data, meaning the name, phone number, and address a company already publishes for customers to find, is generally fine to use for B2B outreach in the US. The real compliance work is honoring opt-outs, keeping a suppression list, and following CAN-SPAM and do-not-call rules for the message itself, not the lookup.

You found a business's name, phone number, and email through a public data tool, and now you are not sure if you are actually allowed to contact them. That hesitation has a cost: a rep who stops to second-guess every list ends up calling nobody. ExtractData pulls business listings from official sources like the Google Places API and Yelp Fusion API, and this guide walks through what public business data actually means for outreach, where do-not-call and email rules apply, and how to keep a list clean without a lawyer on retainer.

What counts as public business data?

Public business data is information a business itself published or registered so customers could find it: its name, street address, phone number, website, hours, and category on Google, Yelp, or its own site. It does not include a private citizen's home address, personal cell number, or financial and health records. That is personal data, and it lives under a different set of rules entirely.

The Google Places API and Yelp Fusion API only return fields a business chose to make discoverable. A dentist's office phone number that rings the front desk is public business data. The dentist's personal cell number, if it ever leaked into a spreadsheet, would not be, and no legitimate outreach tool should be handing that out.

Is it legal to use public business data for sales outreach?

Yes. Contacting a business at the number or address it publishes for public discovery is generally legal in the US. The real compliance question is not whether you can find the information, it is how you contact the business and what you send once you do.

Three federal rules do most of the work here: the Telephone Consumer Protection Act covers autodialed and prerecorded calls or texts, the CAN-SPAM Act covers commercial email, and the Telemarketing Sales Rule covers live and robocall telemarketing. The FTC's own guidance on the Telemarketing Sales Rule lays out a business-to-business exemption that does not exist for consumer calls, which is why B2B outreach and consumer telemarketing are not judged by the same standard.

Does the National Do Not Call Registry apply to business contacts?

The National Do Not Call Registry protects personal residential and mobile numbers a consumer registered on their own. A business's published main line, the one that rings a front desk or routes to a sales team, is not the kind of number the registry was built to cover.

The gray area is the solo operator who runs a business from a personal cell phone. If you are not sure, the FTC's Do Not Call registry lookup lets you check a number before you dial it, and treating that check as a standard step costs a few seconds per lead.

What does CAN-SPAM require in a B2B cold email?

CAN-SPAM is the federal law that sets minimum requirements for any commercial email sent in the US, and it applies to business-to-business email, not just consumer marketing blasts.

Three requirements do most of the work: a truthful subject line and sender identity, a physical postal address in the message, and a working opt-out link that you honor within 10 business days. The FTC's CAN-SPAM compliance guide spells out the full list, and every item on it is a one-time template fix, not an ongoing compliance program.

What's the difference between an opt-out and a suppression list?

An opt-out is one specific person telling you to stop: a reply, a call, an unsubscribe click. A suppression list is the running record you check before every single send, so an opt-out from March never gets contacted again in September because someone re-imported an old spreadsheet.

Most compliance failures are not a bad first message. They are a missing suppression list. The message was fine; the same message just went out twice to someone who already said no.

How to build a suppression list:

  1. Keep one master file of every opt-out, bounce, and "do not contact" reply, regardless of which tool sent the original message.
  2. Check every new list against that master file before the first send, not after a complaint arrives.
  3. Store the business name, domain, and phone number, not just an email address, so a suppression matches across channels.
  4. Re-check the suppression file every time you re-import an old list. A list from six months ago is not automatically current.

Why does sourcing from an official API matter for compliance?

This is the point where hand-built lists usually fall apart. A spreadsheet copied from a dozen random sites mixes public business fields with personal ones, has no record of where each row came from, and gives you nothing to point to if a recipient asks why you have their information.

ExtractData only pulls from the Google Places API, Yelp Fusion API, Outscraper, and SerpAPI: official channels that return business-context fields, not personal social profiles or scraped consumer data. Every record carries its source, which matters the moment someone asks where you got it.

The Pro plan adds Outscraper enrichment and email extraction on top of that same official-source data, so the enrichment step does not introduce data your business justification does not already cover.

How do I build a compliant outreach list from public data?

Start narrow: pick one zip code and one trade, pull the business listings, and check each phone number and email against your suppression file before the first touch. Wide, unfiltered lists are where compliance risk and wasted sends both live.

  1. Pick one zip code and one trade so the list stays reviewable by a human, not just a machine.
  2. Pull the listing through an official API and keep the source and pull date attached to each row.
  3. Check every phone number and email against your suppression file before the first touch.
  4. Log the first-touch date and channel so nobody on the team repeats the same message inside a week.

From there, verify the data before it reaches your CRM, and log the source of the list, meaning which API, which search, and which date, alongside the list itself. If a recipient ever asks where you got their business phone number, "the number your business publishes on Google, pulled through the Google Places API on that date" is a complete and accurate answer.

What if my legal team still isn't comfortable with this?

The most common objection is some version of "we could get sued for this." It is a fair question, and it deserves a real answer instead of a dismissal.

The honest answer: the legal risk in cold outreach lives almost entirely in the message and the list hygiene, not in the act of looking up a business's own published phone number. Keep a suppression list, honor every opt-out immediately, and source from official APIs instead of scraped personal data. Have your legal team review the message templates, not the fact that you looked up a business address on Google. That is a narrower, cheaper review than blocking outreach entirely, and it pairs well with the cold email practices that already keep reply rates up.

The bottom line

Public business data, a company's own published name, number, and address, is fair game for outreach. Personal data and an unmanaged suppression list are where the real risk sits. Start a free search on ExtractData, pull five businesses in your own territory, and check the source field on each one before you make your first call.

Frequently asked questions

Is it illegal to email a business you found through a public directory?

No. Emailing a business at an address it publishes for public contact, like a sales@ or info@ address, is legal under the CAN-SPAM Act as long as the message is truthfully labeled, includes a physical address, and offers a working unsubscribe link that you honor within 10 business days.

Does the Do Not Call Registry cover a business's main phone line?

Generally no. The registry is built for personal residential and mobile numbers a consumer registered themselves, not the general office line a business publishes on its own Google listing or website for customers to call.

What is the difference between public business data and personal data?

Public business data is information a company published to be found, like its name, address, and main phone number. Personal data is information tied to an individual outside a business context, such as a home address or private cell number, and it follows stricter rules.

Do I need a lawyer to start B2B cold outreach?

Not to look up a business's published contact information, since that information is public by design. It is worth having someone review your email and call templates once for CAN-SPAM and TCPA basics, then reuse those reviewed templates instead of re-checking every new list.

What should I do if a business asks me to stop contacting them?

Add them to your suppression list right away, and check every future list against that file before you send anything. That one habit is what stops the same business from being re-contacted months later after you re-import an old spreadsheet.

Does ExtractData scrape social media profiles or personal data?

No. ExtractData pulls business listings through official channels, the Google Places API, Yelp Fusion API, Outscraper, and SerpAPI, which return business-context fields a company published for discovery, not personal social media data.
