So, you’re looking at a map of Pierce County and trying to figure out where exactly the "Land of Generous People" begins and ends. It’s tricky. If you’ve ever tried to mail a package to someone near South Hill or tried to figure out if your new house is actually in the city limits, you know the Puyallup Washington zip code situation is a bit of a localized headache. People just assume "Puyallup" is one giant block of 98371. It isn't. Not even close.
Honestly, the way the zip codes are laid out tells you more about the history of the Puyallup River Valley than any textbook ever could. You’ve got the old-school downtown vibes, the massive suburban sprawl of South Hill, and those weird pockets where you have a Puyallup address but pay taxes to a completely different municipality. It’s confusing.
The Big Three: Breaking Down 98371, 98372, and 98373
Most people don't realize that your specific Puyallup Washington zip code determines everything from your car insurance rates to how long it takes you to get to the Washington State Fair. Let's look at the core ones.
98371 is basically the "OG" Puyallup. This is the valley floor. If you’re walking past the Pioneer Park Pavilion or grabbing a burger at Don’s Drive-In, you’re in 98371. It’s dense, it’s historic, and it’s where the city's soul lives. But it’s small.
Then you have 98372. This one stretches north and east. It hits the Edgewood border and follows the river. It’s a mix of older residential neighborhoods and some newer developments as you head toward Sumner. If you live here, you're likely dealing with the "valley fog" way more than your friends up the hill.
Then there is the giant: 98373.
This is South Hill. It’s a completely different world. If you’ve ever been stuck in traffic on Meridian at 5:00 PM on a Tuesday, you were probably in 98373. It’s where the growth is. It’s where the Target, the mall, and the endless rows of housing developments sit. The weird part? A huge chunk of 98373 isn't even inside the official Puyallup city limits. It’s unincorporated Pierce County.

The 98374 and 98375 "South Hill" Expansion
As the population exploded over the last twenty years, the postal service had to keep carving out new zones. That’s where 98374 and 98375 come in.
98374 covers the southeastern part of South Hill, heading toward Graham. It’s a bit more "spread out" than the core of the hill. 98375 is even further south. We’re talking about the Lipoma Firs area and the outskirts heading toward Frederickson.
If you live in 98375, you probably tell people you live in Puyallup, but your kids might go to Bethel schools instead of Puyallup schools. It's a common point of confusion for new residents. You see "Puyallup" on your mail, but you’re actually miles away from the Meeker Mansion.
Why Your Zip Code Actually Matters (Beyond Mail)
You might think these numbers are just for the mailman. Wrong. In the Pacific Northwest, and specifically in Pierce County, your zip code is a major data point for insurance companies.
Take 98371 versus 98373.
Insurance companies look at theft rates, traffic accidents, and even flood risks. Living in the 98371 valley means you might be in a lahars zone (the path of potential mudflows from Mt. Rainier). While the risk is statistically low on any given day, it's a real factor in geological surveys. Meanwhile, 98373 on the hill is safe from the river flooding, but the traffic density leads to higher rates of fender-benders, which can sneakily bump up your auto premiums.

There's also the school district overlap. The Puyallup School District is massive, but it doesn't perfectly align with the city boundaries. You can live in the 98372 zip code but be zoned for Sumner-Bonney Lake schools depending on exactly which side of the street you’re on. It's wild.
The "Puyallup Address" Myth
Here is something most people get wrong about the Puyallup Washington zip code system. Just because your address says "Puyallup, WA" doesn't mean you live in the city.
The United States Postal Service (USPS) defines "city" names by the post office that delivers the mail, not by political boundaries. This is why thousands of people in the 98373, 98374, and 98375 zip codes have a Puyallup address but can’t vote for the Puyallup Mayor. They live in unincorporated Pierce County.
Why does this matter?
- Law Enforcement: If you’re in the city (mostly 98371 and parts of 98372), the Puyallup PD responds to your calls. If you’re in the unincorporated zip codes, it’s the Pierce County Sheriff.
- Permitting: Want to build a deck? If you're in the 98375 zip code, you’re likely heading to the county office in Tacoma, not the city hall downtown.
- Utilities: City residents often have different water and sewer rates than those on the hill who might be using private companies or county services.
The Hidden Complexity of 98391 and 98390
Sometimes, a "Puyallup" search will lead you into Bonney Lake (98391) or Sumner (98390). These areas are so intertwined that the borders feel invisible. If you're looking for real estate, you'll often see listings labeled as Puyallup that are actually technically in neighboring towns.
This happens a lot near the Shaw Road area. Shaw Road is a major artery connecting the valley to the hill. It cuts through multiple zones. You could start your drive in 98372 and end up in 98374 in about ten minutes, passing through three different "micro-climates" of local government.

What You Should Actually Do With This Info
If you are moving to the area or trying to set up a business, don't just trust a "Puyallup" label. You need to verify the specific zip code against the Pierce County Assessor-Treasurer maps.
Check the School Boundaries First
If you have kids, do not assume a 98373 zip code puts you in the Puyallup School District. Look at the specific parcel map. Some of these zip codes bleed into the Bethel and Orting school districts.
Confirm Your Tax Rate
Sales tax in Washington is destination-based. The tax rate in the city of Puyallup might be slightly different than in unincorporated Pierce County. If you're buying a car or a big appliance, that half-percent difference actually adds up.
Check the Flood and Lahar Maps
If you’re looking at 98371 or 98372, look at the USGS volcanic hazard maps. It sounds dramatic, but it’s a standard part of living in the shadow of Rainier. It affects your insurance and your peace of mind.
The Puyallup Washington zip code you choose defines your daily life—from where you buy groceries to which police officer shows up if you have a fender-bender. It’s a patchwork. Take the time to look at a physical map before you sign a lease or buy a house based on the name of the city alone.
Next Steps for Residents and Newcomers:
- Verify Jurisdictions: Use the Pierce County "About My Property" tool to see if your specific zip code falls under City of Puyallup or County jurisdiction.
- Update Your Insurance: If you've moved from the 98371 valley to the 98375 outskirts, call your agent. Your rates should change based on the shift in traffic density and environmental risk.
- Check Voter Registration: Ensure your registration matches your actual municipality, not just your mailing city, especially before local elections.
