Finding the right post office in a city like New Brunswick isn't always as simple as hitting "near me" on a map. You've probably been there: standing on a sidewalk with a heavy box, staring at a building that looks like a post office but doesn't actually offer retail services. Or worse, you show up at 4:55 PM only to find the doors locked tight. Navigating USPS New Brunswick NJ services requires a bit of local "insider" knowledge because the system here is spread out across several distinct hubs.
Honestly, the "main" office isn't always the best one for what you need. If you're looking for passports, that’s one location. If you’re just dropping off a pre-labeled package, a kiosk might be better.

The Main Hub: 86 Bayard Street
If you're in the heart of downtown, the New Brunswick Post Office at 86 Bayard St is likely your go-to. It's nestled right near the government buildings and the courthouse. Parking? It's mostly street parking. That means you should be prepared to circle the block a few times or pay for a meter.
This location is the primary retail center. They handle the standard stuff—stamps, money orders, and shipping. But here is the kicker: they don't do everything. For example, if you're hunting for a passport appointment, you might find yourself redirected elsewhere.
Hours of Operation:
- Monday–Friday: 8:00 AM – 5:00 PM
- Saturday: 8:00 AM – 12:00 PM
- Sunday: Closed
The lines here can get long, especially during the lunch hour when half of the city's office workers descend on the lobby. If you can swing it, try going around 10:30 AM. It’s usually that sweet spot after the morning rush but before the noon-time crowd.

The Handy Street Alternative
A lot of people forget about the Handy Street Post Office located at 333 Handy St. It’s a bit further south, closer to the residential areas and Cook/Douglass campus. It’s smaller. It’s quieter. But the hours are also a lot tighter.
They usually open at 10:00 AM and close by 4:00 PM. On Saturdays, they are only open from 9:00 AM to 1:00 PM. If you live in the 08901 zip code but don't want to deal with the Bayard Street traffic, this is a solid backup. Just check your watch first.
Passports and the "Secret" County Office
Here is a big tip: many people try to get their passports done at the post office and find that appointments are booked months out. While the Kilmer S&DC (Sorting and Delivery Center) over in Edison or the Monmouth Junction office offer passport services, there's another way.
The Middlesex County Clerk’s Office right in New Brunswick often handles passport applications. They are located at 75 Bayard Street—literally right down the street from the main post office. Sometimes it's way easier to get an appointment there than at a crowded USPS retail lobby. They even have extended hours on certain Tuesdays until 6:00 PM, which is a lifesaver for anyone working a 9-to-5.
The Kilmer S&DC: The Powerhouse
You can't talk about mail in this area without mentioning Kilmer. Technically, it's located at 21 Kilmer Rd in Edison, but it’s the primary processing hub for almost all of New Brunswick’s mail. Recently, the USPS has been pouring millions into this facility.
In late 2025, they unveiled brand-new sorting machines and a fleet of upgraded electric delivery vehicles. This is part of the "Delivering for America" plan. What does that mean for you? Ideally, fewer "package delayed" notifications.
Kilmer also has a 24-hour self-service kiosk. If you have a package with a label already on it, or you need to buy postage at 2:00 AM on a Tuesday, Kilmer is the place. The lobby for the kiosk is open basically all the time.
Dealing with the Rutgers Factor
New Brunswick is a college town. That means mail gets weird in August and May. When thousands of students move in or out, the volume of packages at the local offices skyrockets.

If you are a student or living near the university, use Informed Delivery. It’s a free service that emails you a grayscale image of your mail before it arrives. It’s basically a crystal ball for your mailbox. In a dense city where mail theft can occasionally be an issue, knowing exactly what is supposed to be in your box is huge.
Practical Tips for Success
Don't just show up and hope for the best.
- Bring your own tape. The post office charges a premium for it. If you're shipping a bunch of boxes, buy a roll at the dollar store first.
- Use the Kiosks. If the line at Bayard Street is out the door, check the lobby for the APC (Automated Postal Center). You can weigh packages and print labels yourself.
- Check the "Last Collection" time. If you drop a letter in a blue box at 5:30 PM, it's not moving until tomorrow. Most boxes in New Brunswick have their final pickup at 5:00 PM.
- PO Boxes. If you’re worried about package security, renting a PO Box at the Bayard Street station is a smart move. They have several sizes, but the small ones (Size 1) go fast.
New Brunswick mail delivery is handled by carriers who often have to navigate narrow streets and tight parking. If your house has a porch, consider a lockbox. If you're in an apartment, make sure your name is clearly marked inside the mailbox lid. Carriers in this district are often told not to deliver mail if the name doesn't match their records, especially in high-turnover rental areas.
To ensure your next visit or shipment goes smoothly, download the USPS mobile app to track your packages in real-time and use the "Click-N-Ship" feature to pay for postage at home, which allows you to skip the retail line entirely at the Bayard Street or Handy Street locations.
