Your phone number was shared without your permission. Here is why.
Why spam calls can start after one signup, how phone numbers move through checkout and marketing tools, and what to do next.
The simple answer
Your phone number usually leaks through boring pipes, not dramatic hacks. You enter it into one store, checkout, app, form, coupon page or delivery flow. Then that number can move into marketing, analytics, customer support, identity, checkout and advertising tools.
Sometimes the company collected it directly. Sometimes a partner or embedded tool already knows it. Either way, the result feels the same to you: you gave your number once, and suddenly the internet behaves like everyone has it.

Phone numbers are identity keys.
In the State of Privacy investigation, phone numbers often sat inside checkout, marketing and identity flows. That matters because a phone number can connect visits, purchases, ads and follow-up calls across different places.
