Country coverage
Google Maps scraper USA
The US is the largest local business market on Maps and the one where a single search hits its result ceiling fastest. Covering a state properly means working metro by metro, and often ZIP by ZIP in the dense ones. This page covers how to structure that, and the rules that apply once the list is built.
What you get
- Search by city, metro area or ZIP code for dense coverage
- Full 50-state coverage, worked market by market
- US phone formats captured as listed, ready to normalise
- ZIP code retained in the address string for territory splits
- Filters for website status, rating band and review volume
- Export sized for CRM import rather than one giant file
Work metros, not states
Plumbers in California returns a small slice of the plumbers in California, no matter how long you scroll, because Google caps results per query. The workable unit is the metro: Los Angeles, San Diego, San Jose, Fresno, Sacramento and so on down the population list. In New York, Chicago or LA you will often need to go a level finer and search by borough, neighbourhood or ZIP.
ZIP codes make territory assignment easy
The ZIP sits inside the exported address string, and pulling it into its own column is a five-minute job in a spreadsheet. Once it is there you can assign territories by ZIP range, split a list between reps geographically, and spot which parts of a metro you have not covered yet. For field sales teams this is usually the most useful post-export step.
Which US categories carry the most usable data
Home services fill the phone column almost completely and the website column unevenly, which makes them ideal for web design and lead gen offers. Professional services such as law, accounting and dental publish email addresses far more often. Restaurants and retail have high review volume but the weakest email coverage. Pick the category first and let it set your channel, not the other way round.
CAN-SPAM in practice
CAN-SPAM does not require prior consent for commercial email, which makes US B2B outreach more permissive than Europe. It does require accurate headers and subject lines, a physical postal address in the message, a working opt-out, and that you honour opt-outs within ten business days. Penalties are per-email, so a sloppy campaign to a large list is an expensive mistake rather than a small one.
State-level calling rules
Federal telemarketing rules plus the National Do Not Call Registry are the baseline, and several states add their own requirements on top, including calling-hour restrictions and registration in some cases. Business-to-business calling is treated differently from consumer calling but not always exempt. Check the rules for the states you are dialling into before a calling list goes live.
Frequently asked questions
Why does a statewide search return so few results?
Google caps results per query. Coverage comes from running the search per metro, and per ZIP or neighbourhood in dense cities, rather than from one statewide query.
Can I split a list by ZIP code?
Yes. The ZIP is inside the exported address string, and extracting it into its own column makes territory assignment straightforward.
Does CAN-SPAM require consent before emailing a business?
No, it does not require prior consent. It does require accurate headers, a physical postal address, a working opt-out and that opt-outs are honoured within ten business days.
Which US categories give the best email coverage?
Professional services such as law, accounting and dental publish addresses most often. Restaurants and retail are the weakest for email and better worked by phone.
Do do-not-call rules apply to B2B calls?
Business calling is treated differently from consumer calling, but not always exempt, and several states add their own rules. Check the states you are dialling.
