Coverage by region — what differs
MapsHarvest covers every US state and Washington, D.C. Business density and, in a few cases, the local calling rules differ by region:
TCPA, the DNC Registry & CAN-SPAM — what governs your outreach
Building a list from public Google Maps listings is legal — the rules that matter kick in once you start contacting the businesses on it. In the US, that means three separate frameworks, not one:
The TCPA governs how you call or text — not whether you can build the list
Building a list from public Google Maps listings is legal on its own. The Telephone Consumer Protection Act (TCPA) is the federal law that actually restricts contacting the numbers on it: it requires prior express consent before using an autodialer or a prerecorded/artificial voice to call or text a wireless number, and violations carry statutory damages of $500–$1,500 per call, with no cap on how many calls a plaintiff can claim.
The National Do Not Call Registry mainly protects residential numbers
The National DNC Registry restricts telemarketing calls to residential numbers registered on it. Business-to-business calls to a company's published business line generally fall outside its scope — but the moment a call touches a personal cell phone (increasingly common for small-business owners), TCPA autodialer rules apply regardless of whether the number is technically 'business' or 'residential.'
CAN-SPAM governs email — and it's opt-out, not opt-in
Unlike the UK's PECR or the EU's GDPR, the US CAN-SPAM Act does not require prior consent before sending a first commercial email — a real difference from every other country guide in this series. It requires accurate sender information, a non-deceptive subject line, your physical postal address in the message, and a working opt-out link honored within 10 business days. One important carve-out: CAN-SPAM separately penalizes email sent to addresses obtained through automated harvesting from a site that prohibits it, as an 'aggravated violation' with steeper penalties — worth noting since MapsHarvest doesn't return email addresses at all (a business's website is a field, not its inbox), so any email outreach starts from a domain you looked up yourself, not a harvested address.
A handful of states layer their own private-right-of-action laws on top
Florida's Telephone Solicitation Act (FTSA), Washington's Commercial Electronic Mail Act, and Oklahoma's telemarketing statute each add stricter consent requirements or their own statutory damages, independent of federal law. If a calling or texting campaign touches numbers in those states specifically, check the state law in addition to the TCPA — this is general orientation, not legal advice, and a US telemarketing attorney should review any outreach flow before it scales past a handful of calls.
Who uses US Google Maps data
SDR & sales development teams
Build a state-by-state or metro-by-metro prospecting list without paying for a stale, shared B2B database. Filter for phone number and website presence during the scrape so reps only dial numbers that are actually reachable.
Marketing & web design agencies
Scrape any category — HVAC contractors in Dallas, dentists in Denver, law firms in Charlotte — and filter for businesses with no website or a low rating. Those are the warmest leads for a design, SEO, or reputation-management pitch, and you'll have the list before your first outreach email goes out.
Franchise & multi-location research
Run the same category across every state to map where a competitor or a franchise concept already has coverage and where it doesn't — useful for site-selection research and territory planning before opening a new location.
B2B software & SaaS go-to-market
Segment prospects by state for state-specific compliance needs (insurance, healthcare, finance software), or by metro for a regional account-based marketing push tied to a field sales team's actual territory.
