If you’re typing the zip code for brandywine maryland into a search bar, you probably just want a five-digit number so you can finish an online order or check property taxes. But Brandywine is weird. It isn't a city with clear-cut borders or a mayor. It’s a "Census Designated Place" (CDP) that straddles two different counties, and if you use the wrong numbers, your mail might end up in a different world entirely.
Most of the time, the answer you're looking for is 20613.
That is the primary zip code. It covers the heart of the community, the sprawling new construction developments, and the busy retail hubs along Route 301. But here is the kicker: Brandywine’s identity is split. While the bulk of the population lives in Prince George’s County, a significant chunk of the "Brandywine" mailing area actually bleeds over the border into Charles County.
The 20613 vs. 20601 Confusion
Most people don't realize that zip codes were never meant to define town boundaries. They were invented by the USPS in 1963 to make sorting mail easier. Period. Because of that, the zip code for brandywine maryland can feel like a moving target.
If you live in the southern tip of what locals consider Brandywine—near the Waldorf line—you might actually be assigned 20601. This creates a strange social friction. You might pay Prince George’s County taxes but have a Waldorf mailing address. Or, you might live in Charles County but your kids go to schools across the line. It's a mess. Honestly, it's one of those things that drives real estate agents crazy because a buyer thinks they are moving to one county and realizes during the title search they are technically in another.
Why the Zip Code for Brandywine Maryland Matters for Your Wallet
The five digits you put on your tax return in this area change everything. Since Brandywine sits on the edge of the Washington D.C. metro area, it has become a massive target for developers. We are talking about thousands of new homes in communities like Villages of Brandywine.
Insurance companies love zip codes. They use them to set your car insurance rates based on "territory" risk. In the 20613 area, you’re often lumped into the Prince George’s County risk pool. Historically, this has meant higher premiums compared to the 20601 zip code just a few miles south in Charles County. It's the same road, same driving habits, but a different set of numbers on your mail, and suddenly you're paying an extra $400 a year to insure your Honda.
Then there is the "Quality of Life" factor. Brandywine is transitionary. You have the Cedarville State Forest, which is basically 3,500 acres of swamp, pine trees, and silence. Then, five minutes away, you have the Brandywine Crossing shopping center with a Costco and a movie theater that is perpetually packed. The zip code for brandywine maryland essentially bridges the gap between rural Maryland tobacco country history and the suburban sprawl of the 21st century.
The Logistics of the 20613 Post Office
The actual physical post office for Brandywine is located at 15608 Brandywine Rd. It’s a small brick building that feels way too tiny for the sheer volume of Amazon packages flowing through it these days.

If you are moving here, you need to know about "Last Line" naming. The USPS "preferred city" for 20613 is Brandywine. However, because this zip code covers a vast geographic area, some automated systems might try to auto-fill "Accokeek" or "Clinton" depending on how close you are to those borders. Always override it. Stick with Brandywine. It ensures your local emergency services (which are often dispatched based on complex jurisdictional maps) don't get confused by a ghost address.
The Hidden 20623 Connection
There is a third player in this game: 20623. This is the zip code for Cheltenham, which is right next door. A lot of people who work at the Cheltenham Veterans Cemetery or the nearby military installations technically live in what feels like Brandywine but use the 20623 code.
If you're looking at property near the intersection of Route 301 and Route 5, check the map twice. You might be searching for the zip code for brandywine maryland but actually need the Cheltenham or Clinton (20735) designations to get accurate school district data. Prince George's County Public Schools (PGCPS) uses these boundaries strictly, and being one block over can mean the difference between Gwynn Park High School and a school ten miles away.
Real Estate and the "Brandywine" Brand
Why is everyone obsessed with having a Brandywine address lately? It’s prestige, mostly. In the last decade, Brandywine has rebranded itself from a sleepy crossroads to a "luxury commuter" destination. People want that 20613 stamp because it signifies a certain type of newer, larger home that you can't always find in the older parts of Upper Marlboro or Temple Hills.

But here is a pro tip: if you are buying a house, don't just trust the listing. Check the Maryland Department of Assessments and Taxation (SDAT) website. Plug in the address. Look at the "Tax ID" and the "County" field. I've seen dozens of people get burned because they thought they were in the zip code for brandywine maryland (Prince George's) only to find out their trash pickup and police department are actually out of La Plata in Charles County.
The growth here is aggressive. The traffic on Route 301 at 5:30 PM is proof. That single road handles the weight of two counties worth of commuters, and the infrastructure is constantly playing catch-up. Living in 20613 means you are part of an experiment in how fast a rural area can turn into a city without actually becoming an incorporated city.
Practical Steps for Residents and Newcomers
If you are dealing with a move or a business setup in the area, follow these specific steps to avoid the common "boundary trap" that plagues this part of Maryland:
- Verify your County before signing anything. Go to the Maryland SDAT Real Property Search. Select Prince George's or Charles and type in the street address. If it doesn't show up in one, it's in the other.
- Use the +4 Extension. Because 20613 is so large, your mail will move significantly faster if you use the extra four digits. You can find yours on the official USPS website by using the "Look Up a ZIP Code" tool. It tells the sorter exactly which mail carrier route you're on.
- Check School Zones manually. Do not trust Zillow or Redfin for school boundaries in Brandywine. Use the PGCPS School Finder tool. The 20613 zip code is notorious for having "split" zones where neighbors across the street go to different schools.
- Utility Connections. If you are in the 20613 part of Brandywine, your electric is likely Pepco, but if you drift south into the 20601/Charles County side, you might be on SMECO (Southern Maryland Electric Cooperative). SMECO is often cheaper, so it’s a weirdly important distinction for your monthly budget.
Brandywine is a community in the middle of a massive identity shift. It’s no longer just a place you drive through to get to the Harry Nice Bridge. It’s a hub. Just make sure you know exactly which version of Brandywine you’re standing in before you fill out your next government form.
