Brandywine (20613) is in TWO counties
? 1. Why Brandywine (20613) is in TWO counties
Brandywine, Maryland is: A census-designated place (CDP) in Prince George’s CountyBUT the ZIP code 20613 is a postal area, not a county boundary? That ZIP code actually spreads into: 
Prince George’s County (main Brandywine core) Small adjacent areas that border Charles County? Key rule: ZIP codes = USPS delivery zonesCounties = legal government boundariesSo they overlap — they don’t match.
? 2. Why Brandywine feels like it is in both counties because it is
Brandywine sits right on the county transition zone: North = Prince George’s County core (Clinton, Croom side)South = Charles County (Waldorf, Hughesville direction)? That is why: You see Charles County addresses nearby But still have Brandywine ZIP/mail services
? 3. Accokeek being in BOTH counties Accokeek, Maryland is another border community Mostly in Prince George’s County But it sits directly on the edge of: Charles County (Bryans Road / Waldorf direction) Potomac River corridor? So people say “Accokeek/Charles side” informally, but: Officially Accokeek is Prince George’s County
The confusion comes from:Rural land overlap Postal delivery routesNearby Charles County developments
? 4. Aquasco / Eagle Harbor / Cedarville connection These areas form the southern rural tier of Prince George’s County: Aquasco, Maryland Eagle Harbor, Maryland Cedarville State Forest area They are: Fully inside Prince George’s CountyRight next to Charles County border communities
? 5. Why Charles County and Prince George’s feel “blended”This whole region (Brandywine ? Waldorf ? Accokeek ? Aquasco): Used to be rural farm land Roads follow old colonial boundaries (rivers, creeks) Development expanded unevenly
So today you get: Prince George’s County addresses Charles County shopping/use areasShared school zones, utilities, and commuter routesPrince George’s County
Prince George’s CountyAquascoAquasco = 20608It is NOT in 20613 It is a separate rural ZIP in southern Prince George’s County Located southeast of Brandywine, closer to Patuxent River area

Waldorf (20601–20603) labeled in Charles CountyMalcolm + Danville labeled as community areas (not ZIP codes
