Where Do You Really Live, MoCo?
If you say "North Bethesda" and your friends laugh and call it "Rockville," or if your property value hinges on saying you're in "North Potomac," prepare to have your civic identity challenged.
A new Montgomery Fix map breaking down Montgomery County by its official, primary U.S. Postal Service (USPS) place names shows that Uncle Sam’s mail trucks do not care about your real estate branding.
Silver Spring and Gaithersburg Dominate
Gaithersburg and Silver Spring dominate in size and population. Silver Spring begins at the D.C. border and rolls north through Wheaton, Aspen Hill, and Norbeck, as well as eastward across Colesville and Cloverly The Gaithersburg empire stretches from the borders of Potomac and all the way to the northern agricultural reserve and the Howard County border, a massive footprint that defies actual city limits. The Gaithersburg zip codes encompass 71.9 square miles; City of Gaithersburg proper is 10.3 square miles.
RIP North Bethesda and North Potomac
Real estate agents, look away. If you bought a home boasting a "North Bethesda" or "North Potomac" address, your mail carrier has bad news to deliver. According to official federal routing, North Bethesda is just Rockville (20852), and North Potomac is fully enveloped by Gaithersburg (20878).
The automated sorting machines will still deliver your packages with the boutique neighborhood names, but your mail is getting stamped with a Rockville or Gaithersburg postmark.
Laytonsville Out, Spencerville In
Laytonsville, an actual incorporated town with its own mayor, town council, and historic district, doesn't exist for USPS. The entire 20882 zip code is Gaithersburg.
Meanwhile, on the east side of the county, Spencerville (20868), which is basically an unpopulated stretch of MD-198 with a local post office, retains its own proud, independent sliver of identity right between Burtonsville and Silver Spring.
Some Tiny Communities Make the Cut
While giant populations get lumped together into mega-zones, a few tiny pockets hold their identities in the USPS system.
Washington Grove, a small historic enclave nestled between Gaithersburg and Derwood, has its own dot on the map. Tiny Garrett Park nearly bisects Kensington to earn distinct postal recognition.
In the northwest, Barnesville and Beallsville make the map, as do Sandy Spring, Brinklow, and Ashton in the northeast. And down at the southern tip, the river towns of Glen Echo and Cabin John are carved from Bethesda's border.
Where Do You Live?
Now that you know where you think you live and what the federal government prints on your tax forms may be two entirely different things, are you experiencing a postal existential crisis? Ok, probably not. But the next time someone asks where you're from, maybe you'll pause for a second to think about whether it's Darnestown or Germantown, Wheaton or Silver Spring, or Twinbrook or Rockville.
