With little fanfare, the United States Postal Service announced in the summer of 2008 a new zip code for the southern portion of Alpharetta (and a tiny piece of Milton GA) – zip code 30009. 
While the zip code was created due to growth in the area, unfortunately there is no new post office available to the public planned for the area. If you’ve ever been to the existing post office serving Alpharetta and Milton, you’ll know there is a serious need for another facility, but it’s doubtful one will be built in the foreseeable future.
Though I’m a long-time local resident, I had largely forgotten about the new zip code until writing a recent post about one of my favorite neighborhoods, Providence Oaks, in Milton GA. I then did some further checking of homes for sale in the zip code 30009 and realized that the usage of the new zip code is much like usage of Milton by many agents. Meaning, there are still lots of folks unaware of the official change. So, if you’re looking at homes in the area, be aware of the change and double-check for homes in zip code 30004 as well.
Delivery for this new zip code went into effect on July 1, 2008 with a year-long transition for businesses and residences impacted by the change. A letter-carrier only facility to serve the 30009 zip code is planned in the future. Once the facility is completed, it is anticipated another 40 parking spaces will be available for the existing Alpharetta post office on Old Milton Parkway.
So, if in doubt, check the map for the 30009 zip code to make sure mail is getting efficiently delivered to those you intend.
