Well, it most certainly is the same zip code as the other address is within a 30 second walking distance. It's still frustrating. I did however come up with a temporary solution. In my address field I only put the street name with no number. This at least pins on the correct side of the circle. With this semi-solution the location based reminder will go off when I get home but not exactly at my house just a short distance from it. I say temporary because if I share my contact with friends they won't have my exact address.
I'll get it yet.
