They do pattern matching against lots of pieces of information. It could be as simple as a local utility company selling their customer list with phone number and address attached, then a retail website has your address from when you bought something, now your phone number gets linked.
It doesn't matter if you don't give your phone number to many companies, it only takes one.
Pretty sure my doctor isn't leaking my phone number. I don't give it to companies.
It's also not clear why I would have an uptick in spam calls when I'm traveling. I get 2x/week at home and 2x/day when traveling.
