Rule 50
Address Of The Sender Or Addressee Is Not Written
A postal article in which the address of the sender or addressee is not written clearly, or for some reason, the sender or addressee cannot be traced should be sent to the returned letter section. In case someone suspects that some postal article meant for delivery to oneself has not been able to be delivered on account of an incomplete address, enquiry may be made in writing to the Returned Letter Section.
