Quick show of hands: how many of you have an unlisted phone number?
Especially in today’s world of cellphones, the notion of a “phone book” that is printed on paper and delivered to your house is almost laughable. People purposefully have their phone numbers listed in a phone book as part of being neighborly and accessible, but with the Do Not Call list and robocalls and other phone annoyances, more and more people are choosing to go off the grid (for personal or professional reasons).
With a cell phone, your number is pretty much already unlisted. Nobody should be using your cell number unless you provided it to them.
And so what’s the big deal if someone had your number anyway?
