Suwanee City proper is only 10.7 square miles - meaning that most people who identify as citizens of Suwanee, technically are not.

In fact, there are Suwanee addresses that are in Forsyth - not even the correct county! 
It's confusing, we get it (and we get the calls regarding it all the time).

If you're questioning if you're legit Suwanee, zoom in on the map below. If your house is within the shaded area, congratulations! You're a citizen of the City of Suwanee. Otherwise, you live in Unincorporated Gwinnett or Unincorporated Forsyth  (but we love you nonetheless).
