How to Build a Business List with Phone Numbers
Cold calling still works in trades, local services and B2B, but only with a decent list. Here is how to build one without buying a stale database.
Where phone numbers actually come from
The most reliable public source is each business's own Google Maps listing: businesses keep that number current because customers call it. Across every market we have delivered, 93% of businesses list a phone number and 66% list a website. Some niches run higher: our Pennsylvania tile wholesalers list came back with 100% phone coverage, and Paris electricians with 97%.
Fresh beats big
Resold lead databases decay: businesses close, renumber and rebrand, and the same rows get sold to your competitors for years. A list scanned from Google Maps today reflects today. That is the core design of Maps2Sheets: every scan queries Google's official Places API live, at the moment you run it.
Building the list
Type the niche and area, and the scan counts the market first, free, with sample businesses shown. The complete export lands in Google Sheets or CSV with name, address, phone, website, rating, reviews and category, sorted and deduplicated, for $1.49 to $4.49 depending on size. From there, work the list however you sell: many users sort by review count to call established businesses first, or filter to businesses without websites to pitch web services.
Call responsibly
These are published business numbers, intended to be called, but local telemarketing rules still apply to how and when you call. Check the rules for your country; business-to-business calling is treated more leniently than consumer calling in most places, not exempt everywhere.
Scan your market free and see the phone coverage before you pay anything.
