If a registrant fails to claim and exercise any right or privilege within the required time, he shall be deemed to have abandoned the right or privilege unless the Director of Selective Service, for good cause, waives the time limit.

A document other than a registration card received by an element of the Selective Service System will be considered to have been filed on the date that it is received: Provided, That a document that is received which was transmitted by the United States Postal Service (USPS) and was enclosed in a cover that bears a legible USPS postmark date will be deemed to have been received on that date.

Personnel of the Selective Service System will transmit orders or other official papers addressed to a registrant by handing them to him personally or mailing them to him to the current mailing address last reported by him in writing to the Selective Service System.
