USPS drop-off: 31,000+ post offices, 139,000+ blue boxes (prepaid or under 10 oz stamped), Staples up to 70 lbs, and free door pickup via usps.com. Walgreens and CVS do not accept USPS packages.

Where to Drop Off USPS Packages: All Locations and Rules

USPS packages can be dropped off at any Post Office retail counter, 24/7 post office lobby drop chute, blue street collection box, authorized retail shipper like Staples or Office Depot, or directly from your doorstep using free carrier pickup. Where you should drop your package depends on three factors: whether your postage is prepaid with an electronic tracking barcode, package dimensions, and whether you need an immediate counter acceptance scan.

Where Can You Drop Off Prepaid USPS Packages?

If your package already has a prepaid electronic shipping label (printed from USPS Click-N-Ship, Pirate Ship, eBay, PayPal, or commercial returns), you do not need to wait in the regular counter line. You have several fast-track drop-off choices:

  • Indoor Lobby Parcel Drops: Most post offices feature an oversized drop chute, hopper, or open collection hamper in the lobby labeled “Prepaid Packages Only.” You can walk in, deposit your package, and walk right out.
  • Self-Service Kiosks (APCs): If you want drop-off proof without waiting in line, scan the barcode on your prepaid label at the kiosk. The kiosk prints an official receipt showing the date, time, and tracking number, and opens a secure collection drum for your box.
  • Counter Drop Bins: When lobby chutes are full, most post offices have a designated drop section on the retail counter. You can set your parcel there and leave without standing in line for a postal clerk.
  • Street Collection Boxes: Small prepaid padded mailers and parcels can go directly into any outdoor blue collection box.
  • Free Carrier Pickup: Leave the parcel at your home or office door and request pickup at usps.com.

A note on tracking status: Dropping a prepaid package into a lobby chute or collection box means your first scan happens when postal workers sort outbound mail that evening. If you are shipping a valuable item or need an immediate scan for a marketplace seller deadline, stand in line and ask the retail clerk for an acceptance scan and receipt. You can monitor live movement through every postal hub on our USPS tracking page.

Post Offices: The Full-Service Option

Post offices accept any USPS shipment, whether or not you already have a label. You can purchase postage at the counter, drop a prepaid package with a receipt, ship internationally, buy flat-rate boxes, and buy money orders — all in one visit.

Over 31,000 retail locations nationwide. Use the USPS Post Office Locator to find the nearest location with its current hours and parking.

What to know:

  • Counter service ends at varying times — typically 5 PM on weekdays, noon on Saturdays, closed Sundays.
  • If you arrive during counter hours and have a prepaid label, many post offices have a separate prepaid package drop slot or counter tray (no waiting in line).
  • For packages over 10 oz with postage stamps affixed at home, you must hand-deliver to a USPS employee — you cannot drop an over-10-oz stamped package in a collection box or lobby chute without handing it to a retail clerk.

Can You Drop Off Packages in a USPS Blue Collection Box?

Blue USPS collection boxes are the fastest drop-off option if you already have a prepaid label — no waiting, no counter interaction, available 24/7. There are approximately 139,000 across the country. However, dropping the wrong item can result in severe transit delays or return to sender.

Which Packages a Collection Box Accepts

  1. Prepaid Electronic Shipping Labels: Packages bearing online postage labels (USPS Ground Advantage, Priority Mail, Priority Mail Express, or commercial return labels) with an electronic tracking barcode have no minimum or maximum weight limit in a collection box—provided they physically fit through the opening without being forced. Because online postage links to a verified sender account, electronic labels bypass anonymous mail restrictions.
  2. Postage Stamps (Strict 10 oz Limit): Under federal aviation security regulations, any package or mailpiece paid only with postage stamps that weighs more than 10 ounces or measures more than 1/2 inch thick cannot be placed in a collection box. Stamped items exceeding either threshold must be handed directly to an employee at a Post Office retail counter. Stamped packages over 10 oz placed in a blue box will be held as “Anonymous Mail” and returned to the sender.
  3. Prohibited Items: Never place hazardous materials, lithium batteries, perfumes, liquids, or international shipments requiring a customs declaration in a blue box. For a full breakdown of restricted goods, check our USPS shipping restrictions guide.

Blue Collection Box Size Limits

The standard opening on a blue street collection box features a curved anti-theft hopper designed to prevent hands from reaching inside. The hopper opening is typically restricted to:

  • Height: Approximately 2 to 2.5 inches
  • Width: Approximately 10 to 12 inches

If your parcel is a bubble mailer, flat envelope, or very thin folding carton, it will slide through the hopper easily. Never jam or wedge a package into a collection box. If a box gets stuck in the hopper mechanism, it prevents other mail from dropping securely and leaves your shipment vulnerable to weather and theft. If your package doesn’t slide through effortlessly, take it inside a Post Office or use carrier pickup.

Self-Service Kiosks (APCs)

Automated Postal Center (APC) kiosks are located in post office lobbies and accept credit and debit cards. They can weigh your package, calculate postage, print labels, and give you a receipt with a tracking number — all without interacting with a postal worker.

APC lobbies are typically accessible 24/7 even when the counter is closed, making them the best option for after-hours package drop-offs where you need postage or a receipt. Most kiosks also feature an integrated secure drop drum right next to the machine where you can scan your prepaid barcode, receive a drop-off verification receipt, and deposit the package securely.

Note: Not all post offices have APCs. Check the USPS locator for “Self-Service Kiosks” in your area.

Can You Drop Off USPS Packages at Walgreens?

No. You cannot drop off USPS packages at Walgreens.

This is one of the most common shipping mix-ups, caused by two overlapping facts:

  1. Walgreens is a FedEx OnSite Partner: Walgreens stores feature drop-off and pickup services exclusively for FedEx Express and FedEx Ground shipments. Pharmacy employees are trained and equipped with FedEx scanning hardware, not USPS systems.
  2. Walgreens Sells Postage Stamps: Under the USPS “Stamps to Go” program, Walgreens sells books of First-Class Forever stamps at checkout registers. Selling stamps does not make the store an authorized mail drop location.

If you attempt to leave a USPS package at a Walgreens counter, store clerks will turn it away. If a USPS box is accidentally left behind, FedEx drivers will not touch it, and it will sit unattended until a postal carrier happens to deliver mail to the store.

Similarly, CVS is a UPS Access Point partner, not a USPS partner. Do not drop off USPS packages at CVS.

Where to Go Instead of Pharmacies

If you need a retail drop-off location with convenient evening hours, use an official USPS Approved Postal Provider program partner:

  • Staples: Operates as a full Authorized Postal Service Provider. You can drop off prepaid packages up to 70 lbs, purchase postage, and receive an immediate printed receipt.
  • Office Depot / OfficeMax: Accepts prepaid USPS Ground Advantage and Priority Mail packages and sells retail postal services.
  • PostNet and Private Pack & Ship Stores: Many independent shipping stores are authorized USPS drop-off points. Verify whether they charge an acceptance fee for prepaid drop-offs before handing over your box.

How to Drop Off USPS Packages After Hours

When postal retail windows close (typically 5:00 PM on weekdays and noon on Saturdays), you still have three reliable ways to drop off packages:

  1. 24/7 Post Office Lobbies: Most central and regional Post Offices leave their outer lobby doors unlocked around the clock. These 24-hour lobbies house automated Self-Service Kiosks and large drop chutes that accommodate parcels up to standard shipping sizes. You can weigh boxes, buy postage, print shipping labels, and drop packages late at night.
  2. Outdoor Blue Collection Boxes: Street boxes are accessible 24/7. However, check the collection schedule plate on the box. Most collection boxes have a posted collection time between 4:00 PM and 5:00 PM Monday through Friday (and earlier on Saturday). A package dropped at 8:00 PM on a Tuesday will sit securely in the box until the carrier collects it Wednesday afternoon.
  3. Approved Shippers (Staples & Office Depot): Major office supply retailers stay open until 8:00 PM or 9:00 PM on weeknights. While you can hand your package to store staff until closing, the daily USPS carrier pickup from retail partners usually occurs in the mid-afternoon (between 3:00 PM and 5:00 PM). Dropping an item in the evening means it moves with the next day’s postal dispatch.

Can You Drop Off USPS Packages on Sunday?

Yes, you can physically drop off USPS packages on Sunday, but USPS does not collect, process, or move standard outgoing mail on Sundays.

  • Where you can drop off on Sunday: 24/7 Post Office lobbies, self-service kiosk drop chutes, and outdoor blue collection boxes are accessible all day Sunday.
  • When Sunday drop-offs actually move: Blue collection boxes and lobby chutes are not collected on Sunday. Any package dropped off on Sunday will remain in the receptacle until Monday morning, when postal employees perform their first weekday collection and scan.
  • What about Priority Mail Express? While USPS delivers Priority Mail Express shipments on Sunday in select major metro areas for an added fee, Post Office retail windows are closed and street collections do not run. If you must send an urgent Priority Mail Express parcel on Sunday, you must take it to a major airport postal center or a regional Processing & Distribution Center (P&DC) with an open retail window.
  • Federal Holiday Weekends: If Sunday is followed by a Monday federal holiday (like Memorial Day or Labor Day), packages dropped on Sunday sit until regular collection resumes on Tuesday morning. Consult our USPS holiday schedule to avoid unexpected holiday delays.

Free Carrier Pickup: The Easiest Option

If you have a prepaid label and don’t want to make a trip, free carrier pickup is the most convenient option. Schedule a pickup at USPS.com by midnight (2:00 AM Central Time) for next-business-day pickup from your mailbox, door, or preferred location on your property. The full walkthrough — what qualifies, the missed-pickup fixes, and when the paid $26.50 window is worth it — is in the USPS Package Pickup guide.

Your carrier will pick up packages alongside their regular mail delivery — no additional cost, no trip to a post office. You can also leave packages in your mailbox with the flag raised, though the carrier may not pick them up if they don’t have outgoing mail on your route that day.

Package pickup works for: Priority Mail Express, Priority Mail, USPS Ground Advantage, and most other domestic services with prepaid labels, up to 70 lbs per package.

What Counts as “Prepaid” for Drop-Off Purposes

A prepaid label means:

  • Postage was purchased online (USPS Click-N-Ship, Pirate Ship, Stamps.com, Shippo, eBay, Amazon, etc.).
  • The label shows a tracking number and an electronic delivery confirmation barcode.
  • The weight on the label matches your actual package weight.

If your package weighs more than the label says, USPS automated dimensioning sensors (Automated Package Verification / APV) will detect the difference and bill your online postage account automatically. If you used retail stamps and underpaid, the package may be returned or held for additional postage. Weigh your package before printing the label, or add a small buffer.

Rules That Catch People Off Guard

The stamp weight rule is 10 oz, not 13 oz. Under updated federal aviation security guidelines, any package bearing physical postage stamps that weighs more than 10 oz (or is thicker than 1/2 inch) cannot go into a blue collection box or lobby drop chute. You must hand it in person to a USPS employee at the retail counter. By contrast, prepaid packages with electronic barcodes have no weight limit in collection boxes, provided they fit the slot.

Padded mailers count toward weight. The weight on your label should include the mailer, packaging materials, and contents — not just the product.

Packages with hazmat labels must go to the counter. Anything labeled as containing lithium batteries, liquids, perfumes, or other restricted items cannot go in a blue box or self-service kiosk. See the USPS shipping restrictions guide for the full list.

If you still need to buy the label before you drop it off, USPS Click-N-Ship is the cleanest home workflow.

When to Go to the Counter vs. Drop in a Box

Use the counter when:

  • Your package needs postage (you haven’t purchased a label).
  • Your package uses postage stamps and weighs more than 10 oz or is thicker than 1/2 inch.
  • You need a physical receipt with live clerk acceptance confirmation.
  • You’re shipping internationally and require physical customs forms.
  • Your package contains restricted items requiring carrier acceptance.
  • You need to insure the package for more than the included coverage.

Use a blue box, retail partner, or carrier pickup when:

  • You have a prepaid electronic label.
  • Your package is under 70 lbs (and under 2.5” thick if using a blue street box).
  • You want to avoid the counter line.
  • You’re dropping off outside post office counter hours.

Frequently Asked Questions

Can I drop off a USPS package at The UPS Store?

In limited cases — some UPS Store locations accept prepaid USPS returns as a courtesy if they are an Approved Shipper, but this isn’t standard and there’s no guaranteed same-day forwarding to USPS. For a reliable drop-off with tracking, use a post office, blue box, or an approved retailer like Staples.

Can I drop off a USPS package without a label?

Only at post office counters and Staples (Authorized Postal Service Provider) — these can print labels and accept payment. Blue boxes, kiosks, and third-party drop locations require a prepaid label already attached.

What’s the weight limit for blue USPS collection boxes?

For packages bearing physical postage stamps, the limit is strictly 10 ounces (and no more than 1/2 inch thick) due to aviation security rules. For packages with prepaid electronic shipping labels, there is no weight limit up to the 70 lb postal maximum, though the parcel must physically fit through the 2-to-2.5-inch collection box hopper slot.

Is carrier pickup really free?

Yes. USPS Package Pickup is free for all package types regardless of weight or service. Schedule at USPS.com by midnight for next-business-day pickup.

Do I need to be home for carrier pickup?

No. You can leave packages at your door, mailbox, or in a designated location on your property. Specify the pickup location when scheduling.

Do I have to wait in line to drop off a prepaid USPS package?

No. If your package already has a pre-printed shipping label, you can bypass the retail counter line and drop it into an indoor lobby chute, leave it on the counter drop tray, scan it at a Self-Service Kiosk, or drop it in a blue collection box.

Why hasn’t my tracking updated after dropping my package in a collection box?

Blue collection boxes and lobby drop chutes provide no immediate scan. Your first tracking event—typically an “Accepted at USPS Origin Facility” or “Arrived at USPS Regional Facility” scan—does not appear until the carrier transports the mail to the regional distribution hub that evening. Check our USPS delivery hours guide to understand typical daily transit schedules.
