Four regions, different density and calling rules
Maps Harvest covers every US state and Washington, D.C. Business density and, in a few cases, the local calling rules differ by region:
The TCPA, the DNC Registry and CAN-SPAM govern your outreach
The rules that matter most kick in once you start contacting the businesses on it, and in the US three separate sets of rules apply:
The TCPA governs how you call or text the numbers on your list
The Telephone Consumer Protection Act (TCPA) is the federal law that 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. When a call reaches a personal cell phone, which is common for small-business owners, TCPA autodialer rules apply whether the number counts as 'business' or 'residential'.
CAN-SPAM governs email, and it works on opt-out
The US CAN-SPAM Act doesn't require prior consent before a first commercial email, which sets the US apart from the other country guides 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 carve-out: CAN-SPAM treats email sent to addresses gathered by automated harvesting from a site that prohibits it as an 'aggravated violation', with steeper penalties. Check where each address on your list came from before you mail it.
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, check the state law as well as the TCPA. This is general orientation and not legal advice, and a US telemarketing attorney should review any outreach flow before it scales past a handful of calls.
Four kinds of team that use US Maps data
SDR & sales development teams
Build a state-by-state or metro-by-metro prospecting list without paying for a shared B2B database of uncertain age. Filter for phone number and website during the search so reps only get rows with a number to dial.
Marketing & web design agencies
Pull any category (HVAC contractors in Dallas, dentists in Denver, law firms in Charlotte), filter for businesses with no website, and sort the export by rating to find the low-rated ones. Those are the warmest leads for a design, SEO or reputation-management pitch.
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, which is 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.
