For USPS contact and claim options, start with the latest official tracking event and the shipment service. Domestic Missing Mail searches and insured indemnity claims are separate processes. For lost domestic insured articles, the addressee may need the original mailing receipt or relevant online record. International inquiry starts with the U.S. sender.
Before you act
Check the exact carrier, service, role, and date in the official order or tracking page. A support inquiry, carrier claim, and seller refund are separate paths.
What to do next
Work through these steps in order. Keep the carrier inquiry separate from any request for a seller refund or an insured claim.
- Read the written denial and exact reason.
- Choose Missing Mail Search or insured domestic claim; never imply those are identical.
- For international mail sent from US, only US sender may begin inquiry.
- Keep inquiry number and proof; ask the merchant for order-level relief if a carrier claim does not pay you directly.
Who can act and who may be paid
The roles recorded for this carrier are: sender, recipient if eligible. An online inquiry may be open to a recipient even when the shipper controls a money claim or receives an approved payment. Check your shipping agreement and ask the merchant to take the carrier step if access is restricted.

A filing window is not a finding of eligibility or a promise of payment. Calendar days, business days, and calendar months are different.
Use the named service on the label or order, not the carrier logo alone. A last-mile handoff can also change which company has the parcel.
What to save
- Written claim denial reason
- Additional appeal evidence
- Purchase-value proof
Save the full tracking timeline, order receipt, and any case number on your own device. Submit private records only through the official carrier or seller account.
