I found someone else's package. What do I do?

If it is a private-carrier package (UPS, FedEx, Amazon and similar), open Handback and take photos of the shipping label and the package. You do not need an account to help return it.

Handback reads the delivery details from the label and checks whether a matching recipient exists. If one does, they are asked to verify and claim it, and you can then offer a porch pickup or a public meeting spot.

Handback does not accept U.S. Mail, letters, government correspondence or anything handled by USPS. For those, the app points you to return-to-sender and USPS pickup options instead.
