UPS Frequently Asked Questions: Answers for Shippers

The most common UPS frequently asked questions are about size limits (150 pounds, 108 inches long, 165 inches in length plus girth), PO Boxes (UPS can’t deliver to them), weekend delivery (Saturday in many areas, no standard Sunday service) and claims (report loss or damage within 60 days of the scheduled delivery date). This guide answers each one with the current UPS rule.

Each answer below is short and self-contained, and links to a full ParcelPath guide when the topic needs more depth.

How are UPS shipping rates set, and when do they change?

A UPS rate depends on the service, the billable weight, the zone (distance between origin and destination ZIP Codes) and any surcharges. Billable weight is the greater of the actual weight and the dimensional weight, which UPS calculates as length × width × height divided by 139 for Daily Rates, rounded up.

UPS changes its rates once a year with a General Rate Increase. For 2027, UPS announced an average net increase of 5.9%, effective December 21, 2026, along with a higher minimum billable weight for Additional Handling packages. Fuel surcharges are separate percentages that UPS adjusts weekly.

Because the final price is specific to each box and lane, the easiest check is to compare live UPS and USPS rates in the ParcelPath rate calculator. ParcelPath is free and offers up to 85% off UPS retail rates and up to 89% off USPS, with no subscription or minimum volume.

Does UPS deliver to residential addresses?

Yes. UPS delivers to homes on all of its domestic services, but residential deliveries carry a residential surcharge that business deliveries don’t. UPS decides whether an address is residential during processing, so a home-based business address is usually billed as residential.

Recipients who want to avoid missed doorstep deliveries can send packages to a UPS Access Point or The UPS Store instead. If a shipment is heading to a home and speed isn’t critical, UPS Ground Saver is the economy option built for lightweight residential parcels.

Does UPS deliver on Saturday or Sunday?

UPS delivers on Saturdays in many areas. UPS Ground delivers to residential addresses on Saturday in many ZIP Codes, UPS Ground Saver delivers Monday through Saturday, and Saturday delivery is an add-on option for select air services. Our guide to whether UPS delivers on Saturdays lists the details by service.

UPS has no standard Sunday delivery option for regular parcels. Its around-the-clock UPS Express Critical service is the exception, and the full picture is in our guide to UPS Sunday delivery.

Can UPS deliver to PO Boxes?

No. UPS needs a physical street address because its drivers deliver to the door, so packages addressed only to a PO Box can’t be delivered. If your recipient only has a PO Box, ask for a street address, ship to a UPS Access Point for pickup, or use USPS, which does deliver to PO Boxes.

The key differences between UPS and USPS explain when each carrier fits, and our shipping resources library collects addressing and packaging guides for both.

What are the UPS size and weight limits?

UPS accepts packages up to 150 pounds, up to 108 inches in length and up to 165 inches in combined length and girth (length plus twice the width plus twice the height). Anything larger has to ship as UPS Ground with Freight Pricing or LTL freight.

Within those limits, Additional Handling applies to packages over 50 pounds, longer than 48 inches on the longest side or 30 inches on the second-longest side, or packed in a container that isn’t corrugated cardboard. Packages over 130 inches in length plus girth, or longer than 96 inches, are billed as Large Packages.

Does UPS ship internationally?

Yes. UPS ships internationally to more than 220 countries and territories with services from Worldwide Express Plus to Worldwide Economy. Every international shipment needs customs documentation, and the recipient or shipper pays duties and taxes on top of transportation.

Military mail is a special case: UPS rules for APO, FPO and DPO addresses explain why those shipments usually need USPS for the final leg.

How do UPS pickups and drop-offs work?

You can schedule a one-time UPS pickup online, set up a recurring daily pickup for a business, or hand packages to a UPS driver already making a delivery. Drop-off is free at The UPS Store, UPS Customer Centers, UPS Access Point locations and drop boxes, which you can find in our guide to UPS locations and Access Points.

With ParcelPath, you don’t need a printer for UPS labels: show the UPS Mobile Barcode on your phone at a UPS Store location and the label is printed there. Our article on using UPS on ParcelPath covers the rest of the workflow.

How do UPS damage and loss claims work?

For U.S. shipments, UPS requires notice of loss or damage within 60 days of the scheduled delivery date, and the claim itself must be filed within nine months. UPS’s liability is limited to a default amount per package unless the shipper declared a higher value when the label was created.

1. Report the claim online or by phone at 1-800-742-5877 and give the tracking number.
2. Keep the box, packing materials and damaged item until UPS closes the claim.
3. Upload photos and proof of value, such as an invoice or receipt.
4. Track the claim status online until UPS pays or denies it.

The full process, including who can file, is in our guide to UPS claims and support. ParcelPath shippers can also add Shipsurance coverage when buying a label.

How does UPS tracking work?

Every UPS package gets a tracking number, usually starting with 1Z, at no extra cost. Tracking shows each scan, the scheduled delivery date and, for many residential deliveries, a delivery photo. Our UPS tracking and delivery guide explains each status.

Recipients can sign up for UPS My Choice to get alerts, reroute packages and request a different delivery date. Basic UPS My Choice is free, and our review of whether UPS My Choice is worth it compares it with the paid Premium tier.

What happens after a missed UPS delivery?

If nobody is available to sign or receive a package, UPS leaves a notice and usually tries again on the next business day. After the final attempt, UPS may hold the package at a UPS Access Point, where it waits for seven calendar days, or return it to the sender at the sender’s expense.

Recipients can avoid a return by rescheduling, redirecting the package to an Access Point, or signing a release for a future delivery. If you’ve moved, update your details through a UPS change of address so future packages go to the right place.

Is UPS delivery guaranteed?

Only some UPS services are guaranteed right now. UPS’s money-back Service Guarantee is active for Next Day Air Early, Next Day Air, Next Day Air Saver and 2nd Day Air A.M. within the U.S., and it’s suspended for other services, including 2nd Day Air, 3 Day Select and Ground. When it applies, UPS refunds transportation charges, not the value of the contents.

If a package was refused or you voided a label, refunds work differently. Our guide on how to refund UPS labels on ParcelPath covers unused labels.

Frequently Asked Questions

Can UPS deliver a package that was shipped with USPS?

No. UPS and USPS are separate carriers with separate networks, so UPS can’t deliver or accept responsibility for a package tendered to USPS. The overlap runs the other way: UPS Ground Saver hands some packages to USPS for final delivery. To choose between them, compare whether UPS or USPS is cheaper for your package.

How do I calculate UPS dimensional weight?

Multiply the package’s length, width and height in inches, round each measurement up to the next whole inch, and divide the result by 139. Round up to the next pound. If that dimensional weight is higher than the actual weight, UPS bills the dimensional weight. A tighter box with less empty space lowers it.

Can I change the delivery address after a UPS package ships?

Often, yes. Shippers can request UPS Delivery Intercept to reroute, hold or return a package in transit, and UPS charges only if the intercept is completed. Recipients can make some changes through UPS My Choice, but shippers can block recipient changes, and packages already out for delivery may be too late to redirect.

What items does UPS prohibit?

UPS prohibits or restricts hazardous materials without the right agreement and packaging, firearms except under specific rules, cash and certain valuables, and some perishables. International shipments also follow the destination country’s import bans. Check UPS’s prohibited items list before shipping anything unusual, because a prohibited item can void claim coverage.
