If you’re standing on the corner of Wood Avenue and Elizabeth Avenue, you’re in the heart of a city that feels like the quintessential Jersey crossroads. But honestly, if you're trying to mail a package or set up a utilities account, the zip code of Linden NJ is usually the first thing you need to get right. It sounds simple. It’s 07036. That’s it, right? Well, sort of. While 07036 covers the vast majority of the city, the way the USPS handles this industrial powerhouse of a town is actually a bit more nuanced than a single five-digit number suggests.
Linden isn't just another suburb. It’s a massive hub of commerce, residential neighborhoods, and the famous Bayway Refinery. Because of that mix, knowing the zip code of Linden NJ isn’t just about the numbers; it’s about understanding which "Linden" you’re actually talking about. You've got the residential areas near Sunnyside, the bustling shopping centers on Route 1&9, and the pockets that bleed into Roselle or Elizabeth.

The One Number You Actually Need: 07036
Let’s get the basics out of the way first. 07036 is the primary zip code of Linden NJ. If you live in a house, rent an apartment, or work in a standard office building in the city, this is the code you are using. It’s the identifier for the Linden Post Office located at 400 North Wood Avenue.
It covers a surprisingly large area.
Think about the geography for a second. We are talking about roughly 11 square miles. That includes everything from the quiet streets near Wheeler Park to the heavy industrial zones that dominate the eastern side of the city. Most people don't realize that 07036 is actually one of the busier zip codes in Union County because of the sheer volume of commercial mail generated by the businesses along the corridor.
Why People Search for Other Codes
It’s funny, but people often think Linden has multiple zip codes. They’ll search for "Linden NJ 07037" or "07035." Neither of those exists for Linden. The confusion usually stems from the "Grasselli" or "Warners" areas. Back in the day, these were distinct neighborhoods with their own industrial identities. Today, they are all folded into the zip code of Linden NJ (07036), but the GPS sometimes gets wonky near the borders of Elizabeth (07201/07202) or Rahway (07065).
If you are on the very edge of town near the Rahway River, your mail might feel like it’s in a different world, but the 07036 stamp is what keeps the gears turning.
The Post Office Box Secret: 07039
Here is where it gets a little technical, and where most "quick search" results fail you. If you are a business owner or someone who prefers the security of a P.O. Box, you might encounter 07039.
Wait. Isn't that Livingston?
Yes, actually. This is a classic Jersey mail snafu. While Linden’s primary residential and business code is 07036, there are specific internal routing codes used by the USPS. However, for 99% of people, 07036 is the only number that matters. If you see another number pop up on a weird government database, it’s likely an outdated industrial route or a mistake. Stick to 07036. It’s the gold standard.
Life Inside the 07036: More Than Just Industrial Smoke
People see the refineries from the New Jersey Turnpike and assume the zip code of Linden NJ is just one big factory. That’s such a misconception. Honestly, it’s a city of neighborhoods. You’ve got:
- Sunnyside: Probably the most sought-after residential pocket. It’s quiet, leafy, and feels miles away from the Goethals Bridge.
- Tremley Point: This is where the heavy lifting happens. It’s industrial, rugged, and essential to the East Coast supply chain.
- The 4th Ward: A mix of classic architecture and newer developments.
Each of these areas shares the same zip code, but the property values and "vibe" couldn't be more different. When you’re looking at real estate listings in 07036, the zip code tells you the city, but the ward tells you the story. According to data from the U.S. Census Bureau and local Union County records, the diversity within this single zip code is what makes Linden a "mini-city" rather than just a town.
The Impact of the Linden Airport
Did you know Linden has its own airport? (LDJ). It’s located right in the 07036 zone. It’s a general aviation relief airport, which means it handles smaller planes and helicopters. For hobbyists and certain business travelers, the zip code of Linden NJ is synonymous with easy access to the New York City skyline. It’s these specific landmarks—the airport, the refinery, the shopping at Aviation Plaza—that make 07036 a high-traffic area for both physical mail and digital logistics.
Logistics and Shipping to 07036
If you’re shipping freight—and a lot of people are, given Linden’s location—the zip code of Linden NJ is a major destination for LTL (Less Than Truckload) carriers. Because Linden sits right on the NJ Turnpike (I-95) and Route 1&9, it’s a logistics dream.

But here’s a tip.
If you are shipping to a business in the industrial eastern sector of 07036, always include a gate number or a specific building identifier. These lots are massive. A mail carrier or a FedEx driver might have the right zip code, but without the specific "Suite" or "Building B" designation, your package might end up sitting in a warehouse graveyard for a few days.
Demographic Reality of 07036
The zip code of Linden NJ is home to roughly 43,000 people. It’s a working-class town with a growing professional base. What’s interesting is the median age. It’s a city that’s getting younger as people get priced out of Jersey City and Hoboken and start looking for something with a backyard and a manageable commute.
The commute is the selling point. From the Linden train station (right in the middle of 07036), you can be at New York Penn Station in about 35 to 40 minutes on the North Jersey Coast Line or the Northeast Corridor. That’s faster than some parts of Brooklyn.
Common Errors When Using the Linden Zip Code
I see this all the time with people new to the area. They confuse Linden with Roselle or Roselle Park. While they are right next to each other, Roselle is 07203. If you use 07036 for a Roselle address, your mail is going on a scenic tour of Union County before it reaches its destination.
Another weird one? The "Linden" addresses in neighboring towns. Because of how the post office routes things, some houses on the border might have a Linden mailing address but pay taxes to a different municipality. Always check your tax bill to be sure. But for the most part, if you are within the city limits of Linden, 07036 is your ride-or-die.

Practical Steps for New Residents or Businesses
If you've just moved into the 07036 area or you're launching a business there, don't just rely on the number. Here is what you actually need to do to make sure your "location identity" is solid:
1. Verify with the USPS Look-up Tool
Don't trust Zillow or a third-party site. Go to the official USPS website and plug in your specific street address. This will give you the "ZIP+4" code. Those extra four digits (e.g., 07036-XXXX) are crucial for ensuring your mail doesn't get sorted into the wrong neighborhood pile at the main Wood Ave facility.
2. Update Your Google Business Profile
If you’re a business, Linden is competitive. Make sure your "Linden, NJ 07036" address is consistent across every platform—Yelp, Google, Bing, and your own website. Inconsistency in how the zip code is listed can actually hurt your local SEO rankings.
3. Check Your Utility Zones
Linden’s utilities, like PSE&G and New Jersey American Water, use the zip code to determine service areas. However, because Linden has significant industrial zones, some areas have different "interruptible" power rates. Make sure you specify your 07036 location accurately when setting up accounts to ensure you aren't being billed on a commercial rate if you're in a residential pocket.
4. Register for Local Alerts
The City of Linden uses an emergency alert system. When you register, you’ll be asked for your zip code. This is vital for weather alerts or road closures on Route 1&9, which can be a nightmare during the evening rush.
The zip code of Linden NJ is more than just a piece of data. It’s a key that unlocks one of New Jersey’s most strategically important cities. Whether you’re here for the easy commute, the industrial opportunities, or just a great meal on Wood Avenue, knowing 07036 is the first step to settling in. Just remember: it's one city, one primary zip, and a whole lot of different neighborhoods packed inside.
