How does Redelivery Handle Priority Mail Express?
If the letter carrier cannot deliver the item (for example, if no one is available to sign for the mailpiece or the sender either requested a signature or did not request “Waiver of Signature”), they will leave a PS Form 3849, We ReDeliver for You! (there are no automatic redelivery attempts made after the first attempt for Priority Mail Express®). If the customer does not schedule a Redelivery of any type, a second PS Form 3849 will be left on the 3rd calendar day after the initial attempt.
Note: If you do not schedule a Redelivery by the close of business 5 calendar days from the first attempted delivery, the Priority Mail Express® item will be returned to the sender.

How does Redelivery Handle an Ordinary Mailpiece (Item with No Extra Services)?
When someone is normally available to receive parcels, but an ordinary parcel (i.e., a parcel without any extra services) cannot be delivered on the carrier's first attempt, a second delivery attempt is made the next working day and no PS Form 3849 is left on the initial attempt. If the parcel cannot be delivered on the second attempt, PS Form 3849 is left at the address showing that the parcel is being held.
If no one is available to receive the parcel and the carrier knows that someone at the address is not usually available to receive any parcels; PS Form 3849 is completed and left after the first attempt. When it is not known if someone is usually available to receive parcels, PS Form 3849 is left after the first attempt. Additional attempts are made only at the customer's request.
