What’s the most efficient way to scrape mobile phone numbers for local businesses today, especially for a targeted area, and how can I automate cleaning and formatting?

I’d use Apollo, which returns phone numbers natively, and pair it with Lead Magic for enrichment. Set up your Apollo search with terms like “landscaper” and the city you’re targeting. You can start with the whole U.S. if you need scale. For cleaning, you can strip whitespace, prepend a plus‑one if needed, and run the list through a simple script or GPT‑3.5 to format numbers in seconds. I don’t recommend cold‑calling or SMS; instead send cold emails to qualify interest, then follow up with a call once they’re engaged.
