Where Can I Drop Off USPS Packages?

Once a USPS shipping label is on a package, you have at least seven legitimate ways to hand it off to USPS — not all of them require a trip to the post office. Where you drop off depends on your package size, the service tier, and how much time you have. This guide covers every drop-off option, the size and weight limits at each, hours of access, and which to pick for each scenario.

Quick Decision: Which Drop-Off Should You Use?

Skip to your situation:

• Small package with prepaid postage that fits in a slot: Blue USPS collection box
• Any size package, you don't want to leave home: Schedule free Carrier Pickup
• Package without postage, need it weighed and metered: Post office counter
• After-hours and your local post office is closed: Self-service kiosk in lobby (24/7)
• Want Sunday or evening drop-off without a trip to the post office: Contract Postal Unit (CPU) in a grocery store or pharmacy
• Large package (over 13 oz with postage stamps): MUST be handed to a USPS employee, not dropped in a blue box
• International package: Post office counter required for certain services and customs forms

Option 1: Post Office Counter

The post office counter accepts every type of USPS shipment without restriction. Hand the package to a clerk, who weighs, validates, and applies postage if needed. Best for: anything over 13 oz with stamp postage, packages requiring proof of mailing receipt, certified mail, registered mail, customs forms for international, or any complex situation.

• Hours: typically Mon–Fri 8:30 AM–5:00 PM, Saturday reduced (9:00 AM–1:00 PM)
• Accepts: any USPS service, any size up to 70 lbs
• Pros: full service, expert help available, gets official acceptance receipt
• Cons: lines, limited hours, has to be visited in person

Option 2: Blue USPS Collection Boxes

Blue USPS mailboxes on street corners and outside many businesses accept letters and small packages with prepaid postage. The blue box has a small slot — packages must fit through it without forcing.

• Hours: 24/7 for dropping off; pickup happens at the time printed on the box (typically 5–7 PM weekdays, 1–2 PM Saturday, no pickup Sundays or holidays)
• Accepts: anything that fits through the slot with pre-paid postage and no liquids
• Size limit: about 13 oz with adhesive stamps, or any weight if shipping with online postage (Click-N-Ship, Pirate Ship, etc.)
• Restriction: NO packages over 13 oz with stamps — the security rule prevents stamped packages over 13 oz from being dropped (a leftover anti-terrorism rule)
• Pros: no waiting, available everywhere
• Cons: limited size, no acceptance receipt, won't show as scanned until carrier collects

Option 3: Self-Service Kiosks (SSKs)

Many post office lobbies have automated Self-Service Kiosks that operate 24/7 even when the retail counter is closed. The kiosk weighs your package, calculates postage, prints a label, and accepts the drop-off.

• Hours: 24/7 in lobby (when lobby is unlocked — most are)
• Accepts: packages up to 70 lbs, all USPS services available
• Payment: credit/debit cards only (no cash)
• Pros: full service after hours, no waiting in line
• Cons: not at every post office, no help available if something goes wrong

Option 4: Schedule Free USPS Carrier Pickup

USPS offers free pickup from your home or business — your regular mail carrier collects packages during their normal delivery route. Free for any number of packages, no minimum.

1. Go to usps.com/pickup
2. Enter your address; select the date (next-day pickup is available if you schedule by 2 AM)
3. Specify where to leave packages (front porch, mailbox, back door, etc.)
4. Submit. The carrier collects during normal route — no signature or interaction required

Option 5: Contract Postal Units (CPUs)

Contract Postal Units are USPS-authorized retail counters operated by third parties — usually inside grocery stores (Kroger, Publix, Wegmans, Whole Foods, Safeway, etc.), pharmacies (Walgreens, CVS), or office supply stores. They follow the host retailer's hours, often including Sundays and some federal holidays when traditional post offices are closed.

• Hours: matches host retailer; many open 7 days a week including Sundays
• Accepts: most USPS services (some restrictions; certified mail and bulk shipments may not be available)
• Payment: cash, card, store credit
• Pros: extended hours including Sundays, often less crowded than the post office
• Cons: limited services, sometimes inexperienced staff for complex shipments, no proof-of-mailing scan equivalent at some locations
• Find one: usps.com/locator → filter "Contract Postal Unit"

Option 6: USPS-Authorized Retailers

Several national retailers accept pre-paid USPS packages as a service for their customers. They don't process payments or weigh packages — just collect labeled packages for USPS pickup. Useful when you have a Click-N-Ship or marketplace return label.

• FedEx Office: yes — many FedEx Office locations accept USPS pre-paid drop-offs alongside FedEx shipments
• UPS Store: limited — some accept USPS pre-paid Amazon and marketplace returns; ask before assuming
• Walgreens: many locations accept Amazon returns through USPS; verify locally
• Office Depot, Staples: most locations process USPS pre-paid drop-offs for customers
• Hours: matches host retailer
• Accepts: pre-paid USPS only; no postage purchase

Option 7: Hand to Your Mail Carrier

If your regular mail carrier is on your route at delivery time, you can hand them packages directly. Most carriers are happy to accept pre-paid packages but will not accept anything that needs postage applied.

• When: during your carrier's regular delivery time at your address
• Accepts: pre-paid packages of any reasonable size
• Restriction: cannot weigh, validate, or accept payment — they're delivering, not running a counter service
• Tip: leave packages where the carrier delivers (mailbox, porch, etc.) with a note for them to pick up

Drop-Off Restrictions to Know

Several rules apply to where and how you can drop off USPS packages — knowing them avoids returned packages or refused acceptance:

• 13 oz rule: packages over 13 oz with adhesive stamp postage MUST be handed to a USPS employee or counter — not dropped in any unmanned location. Online postage (Click-N-Ship, Pirate Ship, etc.) is exempt from this rule.
• Restricted items: hazmat packages (lithium batteries shipped alone, aerosols, perfumes, certain liquids) cannot be dropped in unmanned boxes — counter only
• International with customs forms: some destinations require counter validation of customs forms (PS Form 2976 or 2976-A); always counter for international Priority Mail Express
• Cash on Delivery (COD): counter only — never drop unmanned
• Insured items above $200: officially require a counter scan as proof of value declaration

What time is the last pickup at a USPS blue box?

Last pickup is printed on each blue box, usually 5–7 PM on weekdays and 1–2 PM on Saturdays. No pickups on Sundays or federal holidays.

Can I drop off USPS packages on Sunday?

Schedule free USPS Carrier Pickup at usps.com/pickup, drop in a blue collection box, hand to your mail carrier, or use a Self-Service Kiosk or Contract Postal Unit.

Do I need to take USPS packages to the post office?

Not for pre-paid packages — those can go in a blue box (if they fit), to a self-service kiosk, to a CPU, or be picked up free by your carrier. Only packages without postage need a counter visit.

Can I drop off international USPS packages anywhere?

Most international shipments require counter acceptance to validate customs forms and apply restricted-service postage. Domestic-style drop options (blue box, kiosk, carrier pickup) are not reliable for international.
