Introduction: Dropping Off USPS Packages 

USPS is one of the most frequently-used shipping carriers throughout the U.S. It generally offers wider coverage of delivery over different locations in the country at cheaper rates than other shipping services. Such features may benefit customers like a household or small business.

As of July 2022, thousands of post offices have installed over 130,000 USPS collection boxes throughout the country. 

The postal system’s mail collection processes have evolved. For example, tall buildings traditionally used mail chutes that allowed individuals to use slots on different floors of the building to send letters to a depository.

Meanwhile, mailboxes in the lobbies of large buildings have greatly replaced traditional mail chutes.  

Mailing USPS Packages

You should consider not leaving important packages in the big blue mailboxes outside USPS locations. Sometimes people steal from the USPS mailboxes. 

So you should drop off USPS packages over the counter at a post office. Consider handing the package to an employee and requesting an acceptance receipt. The receipt provides proof that you mailed the package. 

If you are dropping off many packages, you can use a shipment confirmation acceptance notice (SCAN) form for more convenience. Postal workers can process the  SCAN form rather than each individual shipping label. 

You also have other options. When your letter carrier drops off your daily mail, you can hand the package to them. An alternative to daily mail carriers is to schedule a free next-day pickup. 

Where to Drop Off USPS Packages

You may wonder how to drop off a USPS package. The process can be confusing since you want to avoid dropping it off at the wrong place among numerous options that exist. 

Besides having several USPS drop-off options, you can use various online tools to locate the nearest location. You can then maximize the efficiency and convenience of your delivery trip. 

USPS Mailboxes

USPS mailboxes are convenient for people who need to send mail. Several types of these “collection boxes” exist and can accept dropped-off letters or packages anytime. 

The mailboxes are available in various sizes and functions. An example is the “Priority Mail Express” collection box. Another option is the “standard collection box.” USPS usually paints these mailboxes blue and adds the USPS logo.  

Kiosks and Contract Postal Units

You can find these self-service kiosks at shopping malls and some post offices. Printing services can provide a prepaid label. This option allows you to avoid time waiting at a post office counter. 

At the kiosk, you can:

  • Buy stamps and shipping labels
  • Print labels
  • Affix stamps and labels to parcels

Going to a self-service kiosk is ideal if you are unfamiliar with USPS prepaid labels or do not own a printer at home.  Some estimates show that two-thirds of online adults in the U.S. used home printers in 2018. 

Contract Postal Units

Generally, most local distribution centers do not accept drop-offs since their primary functions include sorting and distributing mail. 

In case a particular center receives drop-offs, USPS will likely require you to first prepack and label your package. 


As of October 2021, Walmart had over 5,200 retail stores. 

The retail giant is also among the biggest and most accessible official shippers in the USPS system. You can drop off USPS packages at most Walmarts. The USPS website provides a location finder to locate a local Walmart with a USPS shipping service. 


Staples is a famous national retailer that has teamed up with USPS as an approved shipper. The retail company uses both USPS shipping and United Parcel Service (UPS) shipping. Some Staples stores also have a drop box feature like the USPS blue collection boxes. 


Walgreens stores are generally open 24 hours a day, making them an ideal place for dropping off USPS packages. As of July 2022, the pharmacy store has over 9,000 locations. 

You have a few options to drop off USPS packages at Walgreens. You can look for a USPS-labeled drop box or ask for assistance at the customer service counter. 


CVS offers easy accessibility for shipping packages. The process is similar to dropping off packages at Walgreens. You can either look for the drop box containing a USPS label or request assistance at the customer service counter. 

As of July 2022, CVS is the largest pharmacy chain in the U.S. The company was previously known as Consumer Value Store, hence the name CVS.

In some Safeway and Albertsons stores, you can find a USPS-labeled kiosk or desk. Other branches also offer the service through the customer service desks or collection boxes. 


Costco is a good option for grocery shopping if you are seeking bulk groceries. USPS-approved shippers include several Costco stores. However, you usually have to ship your parcels from the customer service desk.  

Sam’s Club

Sam’s Club is another national bulk grocer participating in the USPS-approved shipper program. First, you must verify a Sam’s Club location that takes part in the program. Then drop off your package at the customer service desk.

Where Not to Drop Off USPS Packages

Blue USPS Mailboxes Outside Post Offices

Sometimes crooks target the big blue mailboxes outside the post office. So handing the package to an employee and getting a receipt is ideal. You can also drop off your USPS package over the counter at a post office.  

USPS Distribution Centers

These centers sort and ship parcels. However, the facilities are not:

  • Open to the public 
  • Retail USPS pickup locations

So you usually cannot make a USPS package drop-off. 

What Items Fit Inside a Blue USPS Drop Box?

You can squeeze items of several sizes into the blue box. However, you cannot leave the following items in a U.S. postal mailbox: 

  • Stamped mail weighing more than 13oz  
  • International mail with customs declarations not submitted online
  • International mail needing customs declaration bearing postage stamps

The post office will return any of these items to you. You should drop them off at a USPS retail counter. Remember that these guidelines apply to all 50 states, including California, Florida, New York, Texas, and Utah. 

How Often Post Offices Empty USPS Drop Boxes

The post office empties USPS blue boxes daily. The USPS employee scans the barcode inside the USPS drop-off location to verify the pickup is done by 5:00 PM, Monday through Friday.

Saturday collections vary based on the specific drop box’s average volume of parcels.

What to Do When Unable to Access Drop-Off Points

Suppose your work hours or busy schedule prevent you from getting to the post office or local businesses to drop off a package. You can organize a pickup service. A USPS worker can collect the parcel from your home through Easyship. 

The service may require an additional fee. However, you can save time and energy. You will still have to pack the shipment and add a postage label.  

How to Pack Parcels to Mail Through USPS

Here are some tips to help package parcels effectively:

  • Include a secondary address label inside and outside your parcel so that USPS can still find the intended address should the packaging get damaged. 
  • Use a strong box for any breakable items.
