Peak season puts more parcels on the road than any other time of year, and more of them get lost or damaged. Many shippers miss the window to file claims on them. Below are the carrier deadlines for peak 2026 and the steps that keep claims from lapsing.
Circle January 29, 2027. That's the last day to file a FedEx damage claim on a package you ship this Cyber Monday. It's also the last day the U.S. Postal Service (USPS) will accept a claim for a box you mail that day, whether it’s lost or damaged. By then, your team will likely be buried in returns, and no carrier is going to remind you of the upcoming deadline.
A late claim is usually a lost one. Under UPS’s own terms, a claim that misses the notice window is "deemed waived and will not be paid." Most shipping teams know they typically have 60 days to file. Fewer know when those 60 days start or end.
The Clock Started Before the Box Was Opened
Two of the big three carriers start the clock at your shipping dock. FedEx gives you 60 calendar days from the shipment date to file for damaged or missing contents on U.S. packages. Lost packages get nine months, so damage is the deadline to watch. A gift shipped on Cyber Monday and opened Christmas morning has already used 25 of its 60 days before anyone sees the broken glass.
USPS also counts from the mailing date. Claims for lost or damaged packages are due within 60 days, though for lost Priority Mail and USPS Ground Advantage packages you can’t file until day 15. If a box mailed on Cyber Monday never shows up, your team has about six weeks to notice and file.
UPS counts from delivery instead. Its 2026 tariff requires notice within 60 days after delivery, or within 60 days after the scheduled delivery date if the package never shows up. UPS sets that scheduled date when the label is printed, and it doesn’t always match when a package actually moves.
This summer, a retailer that sends customers prepaid return labels saw hundreds of its UPS claims closed as late. UPS agents told its team that the 60 days ran from a delivery date the system assigned when each label was created, not from when the package moved. One label printed March 31 didn’t ship until May 20, leaving 17 days to file. When the retailer pushed back, UPS reopened fewer than a quarter of the claims.
A return label tucked into a November order may be burning claim days before the gift ever comes back.
Where Peak Claims Go Missing
Plenty of peak losses never become claims at all, often because of a well-meant fix.
A customer emails to say her package never arrived. Customer service ships a replacement the same day, as it should. She's happy, the ticket closes, and nobody files a claim on the first box. You’ve now paid for two shipments and two sets of goods, and the carrier still owes you for the first.
Damage is harder, because the evidence often ends up in your customer's recycling bin. Carriers want photos of the damaged item and its packaging to back up a claim, but customer service teams often issue a refund or replacement without asking for them.
In December, a crushed box sits beside the wrapping paper and is often on the curb by the 26th. Without the box, photos, or proof of value, a claim filed weeks later is hard to support.
No single team owns the claim, either. Customer service owns the angry email, logistics owns the carrier relationship, and finance owns the money. Each team does its job, and the claim falls between them.
What to Fix Before Thanksgiving
Thanksgiving is November 26, so there’s still time to close the gaps that cost nothing to fix.
Build the claims calendar now. Map your expected peak ship dates to each carrier's deadline and put the last filing days on a named person’s calendar.
Rewrite the reship rule. Keep reshipping right away, but open the carrier claim on the original ticket before anyone closes it.
Get photos before you refund. Have agents ask for a photo of the box and one of the item before they issue a replacement or refund, and attach both to the ticket. Keep invoices or other proof of value on file.
Find out when your return labels start the clock. If you use prepaid UPS return labels, ask your account rep, in writing, which date starts the claim window. Get the answer before you print 50,000 of them.
Give claims one owner through February. Pick one person, not a shared inbox, and put a peak recovery number in their January goals.
Where Automation Fits
The steps above cost nothing, but they depend on people tracking deadlines during the busiest weeks of the year. For enterprise shippers, the bigger limit is volume. Carriers don’t offer APIs for filing claims, so every claim goes through a portal or an inbox, one at a time, with different documentation for each carrier.
Automation is built for that scale. A claims tool checks every shipment against its carrier’s window, catches lost packages even after support has sent a replacement, and files with the supporting documents before time runs out. For most high-volume shippers, eligible loss and damage claims add up to about 2 to 3 percent of parcel spend, or $400,000 to $600,000 a year on a $20 million budget. That’s enough to pay for another hire, fund a warehouse project, or offset part of the next carrier rate increase.
Claims automation often gets lumped in with parcel audit, but the two recover different money. Audit checks what you were charged and chases refunds for late deliveries and billing errors. Claims recover the value of the goods you lost. If an audit provider already handles your claims, ask them four questions:
●How many claims did you file for us last quarter?
●Can we see claims reported separately from late-delivery refunds?
●How many eligible lost or damaged shipments went unfiled, and why?
●What is our approval rate, and what happens after a denial?
A strong program answers each one with numbers. If yours can't, find out what your peak claims are worth before January 29.
