Comprehensive Guide to Long Beach Post Offices

You’ll find several post offices in Long Beach, all managed by the United States Postal Service (USPS). Each location has its vibe and hours, from full-service branches to smaller neighborhood stores.
Overview of USPS Locations
USPS branches are sprinkled throughout Long Beach, so getting to one isn’t usually a big deal. The bigger ones—like the main post office on Long Beach Blvd—offer full mailing, shipping, and passport help.
Smaller branches in neighborhoods mostly handle retail sales, PO boxes, and basic package drop-offs. Here’s a quick look at a few:
| Location Name | Address | Services Offered |
|---|---|---|
| Long Beach Post Office | 300 Long Beach Blvd | Full service (USPS) |
| Bixby Knolls Post Office | 4470 Atlantic | Full service, PO Boxes |
| Downtown Long Beach Post Office | 300 Long Beach Blvd | Mailing, shipping, passports |
| Belmont Shore Postal Store | 5050 E 2nd St | Retail, PO Boxes, stamps |
Hours change depending on the spot, with downtown offices usually opening up earlier. Many places offer self-service kiosks and let you schedule package pickups online.
Downtown Long Beach Post Office
The downtown branch at 300 Long Beach Blvd stays pretty busy. It’s the go-to for both residents and businesses in the area.
They handle all the usual USPS stuff—shipping, certified mail, money orders, and passport applications. You can even make a passport appointment and skip the line.
Lobbies stay open late, and the staff knows their stuff when it comes to international shipping or packing supplies. Parking’s behind the building, but it fills up fast, especially at lunch.
People like this branch for its speed and central location. If you’re downtown, it’s tough to beat for quick service.
Belmont Shore Postal Store
The Belmont Shore Postal Store on 2nd Street mainly serves Belmont Shore and Naples. It’s a bit smaller and more relaxed than downtown.
You’ll find it at 5050 E 2nd Street, open Monday to Friday from 8:30 am to 5:00 pm. They focus on retail services—stamps, package drop-off, and P.O. box rentals. Lines are usually short, especially in the mornings. The staff helps with address changes, mail holds, and sending off those holiday gifts.
Locals love this spot for personal service and the convenience of having it right in the neighborhood.
Services and Amenities

Post offices in Long Beach handle a lot more than just letters. Whether you’re a business or just mailing a birthday card, they’ve got you covered with reliable service and secure mail handling.
Mail and Package Services
USPS locations in Long Beach offer a full menu of mail and package options. You can send letters, postcards, or big boxes anywhere in the U.S. or overseas.
They’ve got Priority Mail, Express Mail, and First-Class Mail. Pricing depends on size, weight, and how fast you need it to get there. If you’re not sure, the staff will help you figure it out at the counter.
Need tracking or insurance? That’s available too. Most spots have drop-off bins, self-service kiosks, and plenty of supplies like boxes and envelopes.
Some locations also accept packages from carriers like FedEx and UPS, but there might be some rules or extra fees.
Passport Services
Several post offices in Long Beach help with passport services. If you need to apply for or renew a U.S. passport, you’ll want to check ahead—appointments are usually required, and walk-ins aren’t always an option.
Bring your proof of citizenship, a photo ID, completed forms, and payment. They’ll even take your passport photo for a small fee, so you don’t have to worry about bringing one.
Staff send your application straight to the U.S. State Department. Processing times change, so plan ahead, especially if you’re traveling soon. Not every location does passports every day, so double-check before you go.
PO Boxes and Mailboxes
PO Boxes at Long Beach post offices offer a secure and private way to get your mail. You can pick from different sizes and rent them for 3, 6, or 12 months.
They’re great for early mail pickup, privacy, and safe package delivery. You’ll get a key or code for access during lobby hours.
Some places offer street addressing, which means you can get packages from non-USPS carriers delivered right to your P.O. Box. If you need to get your mail late or early, a few locations even have 24-hour lobby service.
To rent a box, you’ll need to apply in person with a valid ID. Fees depend on the size and location.
Besides the main branches, Long Beach has a few postal facilities that serve different neighborhoods. These include carrier annexes in Spring and North Long Beach. They’re handy for mail sorting and PO box access, but don’t expect full retail service.
Spring Carrier Annex
The Spring Carrier Annex sits at 3019 N Bellflower, Long Beach, CA 90808. It handles mail delivery for Zip Codes 90806, 90807, and some nearby spots.
This isn’t a full-service post office—you can’t buy stamps or mail packages here. The focus is on sorting and distributing mail for carriers. PO box renters can get to their boxes during posted hours.
Most people drive here, since parking’s right next to the building. There’s no counter for regular customer service or package drop-offs.
North Carrier Annex
You’ll find the North Carrier Annex at 3910 Long Beach Blvd, Long Beach, CA 90807. It mostly supports mail carriers for North Long Beach and Bixby Knolls.
This spot sorts and dispatches mail but doesn’t handle passports, retail sales, or outgoing packages from the public. PO box customers can still access their mail during lobby hours.
There’s no front desk for general customer service, but staff move a lot of mail behind the scenes.
Phone Numbers and Operating Hours
Each location has its phone line for asking questions or for support. Here’s a quick table with the main numbers and lobby hours:
| Location | Phone Number | Lobby Hours |
|---|---|---|
| Spring Carrier Annex | (562) 492-5226 | Mon–Fri: 8 am–5 pm |
| North Carrier Annex | (562) 424-2146 | Mon–Fri: 8 am–5 pm |
If you call, you’ll usually reach someone who can answer questions about deliveries or mailbox access. For retail stuff, it’s better to call the main post offices instead of the annexes.
Accessibility and Parking
Both annexes have ground-level entrances and sidewalk ramps, so getting in with a wheelchair or stroller isn’t a problem. Doors are wide and open automatically.
Parking’s free at both spots, but the lots are pretty small. Handicap parking spots sit near the doors and are easy to spot.
Check for posted signs about time limits or restrictions before leaving your car. There aren’t any bike racks at these annexes, but public transit stops are just a short walk away.
Long Beach Post Offices in Context
Post offices in Long Beach keep up with one of the busiest regions in Southern California. They handle thousands of pieces of mail every day and have been a big part of local growth.
Role in Los Angeles County
Long Beach is the second biggest city in LA County, with more than 450,000 people. Its post offices help move mail and packages through a network connecting millions.
They support local businesses and families with regular mail, shipping, and passport services. USPS manages all the Long Beach locations and works with nearby cities like Torrance, Compton, and Signal Hill.

History of the Postal Service in Long Beach
The first post office in Long Beach opened around 1888. Back then, the city was much smaller, with only a handful of neighborhoods.
As more people moved in and businesses popped up, especially after World War II, the need for more post offices really took off. Early post offices often doubled as community meeting spots.
Some of these early locations sat inside general stores or tiny rented spaces. Eventually, the city started building dedicated post office buildings to keep up with everyone’s mail.
Several Long Beach post offices have some real historical charm. For example, the Long Beach Main Post Office building made it onto the National Register of Historic Places.
Some older post offices in town show off changes in architecture and city planning over the years. You can almost see the city’s story in the bricks and design.
