Lost package documentation for resellers: searches, claims and cases

The buyer says it never came

Every reseller who ships enough parcels eventually gets the message: tracking stopped moving, or tracking says delivered and the buyer says it isn't there. What happens next depends on what you can show. A seller with a label receipt, packing photos, the tracking history and proof of what the item cost can work through a marketplace case and a carrier claim calmly. A seller with none of that is guessing.

This guide covers lost package documentation for resellers, using the USPS missing mail and domestic claims pages, the USPS Ground Advantage page, and eBay's help page for buyers whose items haven't arrived, all checked November 8, 2026. Marketplaces have their own protection programs, so read your platform's rules for the case itself.

The evidence file to build for every parcel

You don't know which parcel will go missing, so the documentation has to happen for all of them. Keep it light:

The photo file system guide shows a simple way to keep these photos findable by SKU.

Step 1: Read the tracking carefully

Before contacting anyone, open the tracking history. Note the last scan, its location and date. A parcel that has stopped scanning is different from one marked delivered. The USPS missing mail page says to check USPS Tracking first.

Step 2: Reply to the buyer with facts

Answer promptly, share the tracking status, and say what you will do next. For a "delivered but not received" message, eBay's buyer help page suggests the buyer check around the property, ask neighbors, contact the carrier, check a building's front desk and look at any delivery photo. You can politely suggest the same checks without implying the buyer is wrong.

Step 3: Start a USPS Missing Mail search when eligible

USPS says Missing Mail search requests can be submitted starting 7 days from mailing. The request asks for:

• Sender and recipient mailing addresses.
• Size and type of container.
• Tracking numbers, mailing date or Click-N-Ship label receipt.
• A description of the contents, such as brand, model, color or size.
• Pictures that could help USPS recognize the item.

Your packing photos are exactly what this asks for. USPS also says that sometimes missing mail can't be found.

Step 4: File an insurance claim when the parcel was insured

The USPS claims page says either the sender or the recipient may file a claim for insured mail that is lost, damaged or missing contents. The USPS Ground Advantage page says $100 insurance is included with that service, and more coverage can be bought.

For damaged items or missing contents, USPS says you may file immediately but no later than 60 days after the mailing date. It says to keep the packaging and everything in the package until the claim is settled, not to throw out damaged items, and that you may be asked to bring the package to a Post Office. USPS usually sends decisions within 5 to 10 days, does not pay more than an item's actual value, and allows an appeal within 30 days of a decision.

Worked example: one parcel, two timelines

In this chosen example, a seller mails a $60 jacket by Ground Advantage on November 2. Tracking stops on November 4.

Meanwhile, the buyer may have opened a marketplace case. eBay's help page tells buyers that sellers have up to 3 business days to respond before the buyer can ask eBay to step in. Respond inside that window with tracking and what you've filed.

Keep the marketplace and carrier sides separate

The marketplace case decides what happens with the buyer. The carrier claim decides whether you recover anything for an insured parcel. They run in parallel and don't replace each other. Keep notes of every case number and date in your inventory record.

Records note: If you refund a buyer and later receive a claim payment, record both. The refund records guide covers keeping refunds and reimbursements straight.

Reduce the chance next time

• Use a service with tracking and included insurance for anything valuable.
• Photograph every parcel before it's sealed.
• Write the SKU on the packing slip, not on the outside.
• Use the weighing guide so labels match the parcel.

Common mistakes

• Filing a claim before the waiting period has passed.
• Throwing away a damaged item or box before a claim is settled.
• Missing a marketplace response deadline.
• Having no proof of value.
• Arguing with the buyer instead of documenting.

Paper beats memory

A lost package is a records problem first and a shipping problem second. Save the label, photos and proof of value for every parcel, and the search, the claim and the buyer case each take minutes instead of days.
