> my strategy is to live in a different place than my area code and only pick up from number that do not share my area code. This is pretty clise to working but I did almost miss an instacart delivery because they happened to be from my home town.

I'm in that situation, and it works most but not all of the time.

I don't really keep track, but I'm pretty sure I've gotten robocalls with an area code appropriate to my city, either it was coincidence or they were using a database that had my actual location.
