9. Map It Out
It's quite easy to see the location of a delivery address thanks to Street View in Google Maps and other map applications and sites. Check out the delivery address and if it looks like a residential location -- and not the headquarters of a large commercial company -- be wary, Bares said.
He also recommends doing a search with just the street and town. "If it's a big company, you should get tons of hits [for the company on that street]. If nothing shows up, you have an issue," Bares said.
