How to Find US Post Office Locations

You can find a nearby Post Office for a USPS drop-off by clicking the Locations tab on the USPS website. Under location type, choose “Post Offices”, enter in your city and state, or ZIP code, and choose your radius (between 1-100 miles).

You’ll also be able to see operating hours and parking available for all results.

2. USPS Mailboxes (Or Blue Boxes)

Also known as collection boxes, you can find over 139,000 blue USPS package drop-off boxes around the US.

Typically, these are blue standalone units on street corners. But collection boxes can also be wall-mounted drop-offs or designated mail chutes within a USPS building.

How to Find a USPS Mailbox Near You

You’ll be shown the address of all USPS package drop-off boxes in your specified area, plus the daily collection times.

Don't Drop Off at USPS Distribution Centers

USPS distribution centers (or Network Distribution Centers) are where parcels are sorted for shipment. Once mail and parcels are processed here, they are then sent to sectional center facilities, which are located in designated regional areas. These facilities continue to route mail to local post offices and their final destination.

These facilities aren't open to the public nor are they retail USPS pickup locations. This means you typically cannot use these centers for a USPS package drop-off.

What Fits Inside a Blue USPS DropBox?

While you can just buy stamps and cram items of many sizes in a blue box, the Post Office won't ship everything they find inside. A few restrictions apply to what can be dropped off for delivery in a USPS mailbox. The following cannot be left in a U.S. postal mailbox:

  • Any stamped mail weighing over 13 oz.
  • International mail with customs declarations that weren't submitted online
  • International mail requiring a customs declaration that bears postage stamps

If you leave any of the above items in a USPS drop-off mailbox, they will be returned to you. It's better to drop these items off at any USPS retail counter

13 oz. is less than a pound, meaning that most packages for eCommerce will need to be dropped at the Post Office, or be arranged for pickup at your business location.

How Often Do USPS Drop Boxes Get Emptied?

Every active USPS blue box is emptied daily. A USPS employee must scan the barcode inside the USPS drop-off location to confirm this pickup no later than 5 PM, Monday through Friday.

Saturday collections vary depending on the average volume of parcels in that specific drop box.

USPS Package Drop Off FAQ

Can you put a flat rate box in a USPS dropbox?

Unfortunately not. Nothing that weighs over 13 ounces can be shipped from a USPS dropbox, and the box itself is too heavy (nor would it fit in the aperture at the top).

Can you drop off packages at USPS on Sunday?

USPS doesn't accept packages on Sunday. You can drop items in mail collection boxes on Sundays for Monday pickup, assuming they're not oversized.

Can you drop off USPS at Walgreens, Staples, or Walmart?

Retailers like Walgreens, Staples, and Walmarts do accept USPS package drop-offs – assuming there's a FedEx counter inside. Check your local search results to determine if these services are available at your local retailers.

Are USPS drop boxes safe?

It's more secure to drop off packages at USPS or schedule a pickup. Thieves have been known to break into blue boxes, though this is rare.
