YSK: if your FedEx or UPS packages are frequently delivered to the wrong house(s), Google may have your address at the wrong location
Why YSK: This came up on social site when people were complaining of misdelivered packages and people having to swap packages for the right ones. Someone noticed her address in Google pointed to a spot where her packages often ended up, even if the house number didn't match.
So check Google map of your address. If the marker is not right on your house, make the necessary correction. UPS and FedEx relies on Google map to make the route and with hundreds package per driver per day, the drivers often won't have the time to check the house number or the street name matches the package. They go by what the programmed route states.
I have no idea if Amazon does the same so check anyway if your package keeps getting delivered to the wrong house.
