442 Registered Mail Found With Ordinary Mail

442.1 Disposition

Return to the registered mailstream any item found in the ordinary mail that has been accepted as registered by the Postal Service.

442.2 Complete the Registration Process

Enter for Registered Mail service any item on which the sender has fully prepaid the postage and the registry fee and that has been endorsed to show that registry is desired. Send a mailing receipt (see 334.1) to the sender, including a reminder to the sender that mail to be registered must be presented at the Post Office facility for that purpose.

442.3 Shortpaid Mail

If the item has not been fully prepaid, return it to the sender after indicating that it is shortpaid and must be presented for registry at a Post Office facility. If the shortpaid registered item bears no return address, cross out the sender’s registry endorsement and dispatch as ordinary mail.
