Spam calls and google search results for these numbers

RE the OP question…

I’m just going from (faulty) memory here, but there used to be a database of thousands of fake phone numbers and names, all obviously computer generated. It was originally intended to be a “practice” database for some application, but got released to the public, and some search engines picked it up. Like many stupid computer decisions, the search engines were unable to distinguish between the real and the fantasy, and were linking real numbers to the fake database. Maybe this – or something like it – is the source of your interesting fake names?
