Do I have to return an Amazon package that isn't mine?
No. The FTC's rule on unordered merchandise says you never have to pay for, or return, something you received but did not order (per consumer.ftc.gov, checked 2026-08-30). A misdirected Amazon box lands under the same principle: you did not order it, so nothing is owed by you, whatever you decide to do with it next.
Can I use USPS Package Intercept or a carrier misdelivery case for an Amazon package?
Only if the tracking number actually belongs to USPS, UPS or FedEx. Most Amazon boxes move on Amazon's own delivery network, and neither a public carrier account nor a carrier's misdelivery case reaches that network. If your tracking number reads like an ordinary carrier number, our package delivered to the wrong address guide covers what to do next.
My own Amazon order went to the wrong address. What do I do?
Report it from Your Orders rather than a carrier. Amazon's own tools sit inside the order record, and a refund or a replacement comes from there. When a third-party Marketplace seller shipped the order and will not fix it directly, Amazon's A-to-z Guarantee is the backstop. There is no separate carrier claim running alongside it, because the delivery never touched a public carrier account.
How do I know if a package moved through Amazon's own network or a carrier?
Look at the tracking number on the order page or the label itself. A number starting with the letters TBA belongs to Amazon's own delivery network. Anything shaped like an ordinary USPS, UPS or FedEx tracking number moved on that carrier's public network instead, with that carrier's own remedies attached to it.
What does it cost to mail a misdelivered box back voluntarily?
Nothing is owed, but for a sense of the number: a 12 x 10 x 6 in box at 3 lb from Newark, NJ to Atlanta, GA quoted $9.48 with USPS Ground Advantage through the SMKlog calculator on 2026-08-30. Your own box and lane will price differently.
