Yes, and many people do. Hence this comic: https://xkcd.com/1129/ https://xkcd.com/1129/ (the first three digits being the area code). Edit: keeping my number when I moved also made it really easy to filter out these phone calls. Any number calling me from my old area code that I don't recognize is either a spammer or a wrong number. Any number calling me from my new area code is probably legitimate.
