You’re looking for a Jasper Texas zip code and you probably think it's a simple five-digit answer. It is. But also, it kind of isn't.
If you just need the number to mail a birthday card or fill out an online checkout form, here it is: 75951. That is the primary code for the City of Jasper. However, if you are moving to the area, looking at real estate near Sam Rayburn Reservoir, or trying to figure out why your GPS is acting funky near the Angelina National Forest, there is a whole lot more nuance to the geography of Deep East Texas than just one string of numbers.
People often get 75951 mixed up with the surrounding rural routes. It happens all the time.
The Logistics of 75951 and Its Neighbors
Jasper is the county seat. Because of that, the 75951 zip code covers a massive amount of physical ground. We are talking about roughly 430 square miles of pine trees, rolling hills, and scattered homesteads. When you look at a map of East Texas, this zip code looks like a giant irregular blotch that anchors the southern end of the "Piney Woods."

But here is where the confusion starts for locals and newcomers alike.
Jasper County is huge. If you drive twenty minutes in almost any direction, you might still have a Jasper address, but you could easily drift into the service areas of other smaller post offices. For example, if you head north toward the lake, you start running into 75931 (Brookeland). If you go west toward the Neches River, you might find yourself dealing with 75979 (Woodville) or even 75936 (Chester) territory.
Why does this matter? Well, for one, mail delivery in these rural stretches isn't always what you'd call "standard."
In the heart of Jasper, specifically around the historic courthouse square and the commercial strip on Highway 190, 75951 is the undisputed king. You have the main post office right there on North Main Street. But the further you get from that brick building, the more the lines blur. Honestly, some folks living in the outskirts have a Jasper physical address but get their mail through a completely different town's route. It’s a quirk of the USPS rural delivery system that has existed for decades.
A Quick Breakdown of the 75951 Perimeter
- Main City Limits: This is your standard residential and business mail.
- The Rural Routes: These extend deep into the woods. If you're on a "County Road" (CR), your mail carrier is likely driving a specialized vehicle to reach you.
- PO Boxes: Many businesses and long-time residents prefer the security of the North Main Street post office boxes to avoid the "mailbox baseball" often played on rural roads.
Why the Post Office Location is the True Anchor
If you’re actually in town, you’re going to be visiting the post office at 210 N Main St, Jasper, TX 75951. This isn't just a place to buy stamps. In a town like Jasper, it’s a bit of a social hub. You’ll see the same people there every morning at 9:00 AM checking their boxes.
The 75951 zip code doesn't just represent a town; it represents a specific lifestyle.
It’s the gateway to the "Big Thicket." Living in this zip code means you’re roughly 130 miles northeast of Houston and about 30 miles from the Louisiana border. You’re in the land of the Jasper Bulldogs. You’re in a place where the weather is measured in "humidity levels" rather than just degrees.
The Real Estate Reality of Jasper Texas Zip Code
If you are browsing Zillow or Redfin for property, you have to be careful with the 75951 filter.
Because the zip code is so expansive, a "Jasper, TX 75951" listing could be a cute Victorian home near the city center, or it could be 50 acres of raw timberland thirty minutes away from the nearest grocery store. I've seen people buy "Jasper" property thinking they’d be close to the stores, only to realize they are basically neighbors with a national forest.
Check the "plus four" on the zip code. That extra four-digit suffix—like 75951-xxxx—is actually super helpful here. It tells the postal service (and savvy residents) exactly which rural route or city block the mail is headed to. Without it, mail sorting for such a large geographic area would be a nightmare.
Misconceptions About Local Delivery
A lot of people think that a zip code defines a city's boundary. It doesn't.
Zip codes are for the convenience of the post office, not for tax authorities or school districts. You can live in 75951 and be outside the city limits. This means you don't pay city taxes, but you also don't get city water or trash pickup. On the flip side, some people think 75951 covers the entirety of Lake Sam Rayburn. It doesn't even come close. The lake is so big it’s split between multiple zip codes and several counties including Angelina, San Augustine, and Sabine.
Demographics and Data Within 75951
Let’s talk numbers, but keep it real.
The population within the 75951 area fluctuates, but it usually hovers around 15,000 to 18,000 people depending on how far out you draw the circle. It’s a diverse mix. You have multi-generational logging families, retirees who wanted to be near the fishing, and folks who work at the local hospitals or school districts.
The median home value in 75951 is generally lower than the Texas state average, which is why it’s such a magnet for people looking to escape the skyrocketing costs of Austin or Dallas. You can get a lot of "dirt" for your dollar here. But, and this is a big "but," you have to factor in the cost of driving. In 75951, you aren't walking to the store. You are driving ten miles just to get a gallon of milk if you live on the wrong side of the creek.
Practical Tips for Using the Jasper TX Zip Code
If you’re sending something important, or if you’re moving here, keep these things in mind.
- Verify the County: Just because it says 75951 doesn't mean it's strictly Jasper County, though 99% of it is. The fringes can be tricky.
- GPS vs. Reality: Sometimes, Google Maps will get confused by rural Jasper addresses. If you’re trying to find a house out in the woods, ask the resident for the "mailing address" versus the "physical location." Sometimes they aren't the same.
- Shipping Carriers: UPS and FedEx know 75951 well, but they sometimes struggle with the "private roads" that branch off the main county roads. Always provide a phone number on your shipping labels for this zip code.
Jasper is a place defined by its trees and its water. The 75951 zip code is the digital handshake that connects this quiet, forest-heavy region to the rest of the world. Whether you are coming for the Jasper Lions Club Rodeo or just passing through on your way to Toledo Bend, knowing the layout of the land—and its primary zip code—makes life a whole lot easier.
Actionable Steps for New Residents or Visitors
- Confirm your specific delivery zone: If you're moving to the outskirts, check with the Jasper Post Office to see if you need a PO Box or if they offer roadside delivery.
- Update your voter registration: Don't rely on your zip code to tell you where to vote. Check the Jasper County Elections Department to find your specific precinct.
- Check the "Plus Four": For faster shipping and accurate insurance quotes, find your full nine-digit zip code using the USPS Look Up tool. This often lowers insurance premiums because it pinpoints your exact fire protection zone.
- Prepare for "No Service": Large swaths of the 75951 rural area have spotty cell service. If you're navigating via GPS, download the offline maps for the Jasper area before you leave the main highway.
