When using the special classes of mail always consider that they will probably be slowed down as they are logged in at each U. S. Post Office and kept track of by hand. They also require someone to be there to accept them for delivery. The registered mail system is designed to provide added protection for valuable mail.
Registered mail is the most secure mail the postal service offers.
It incorporates a system of receipts to monitor registered articles from the point of acceptance to delivery. Return receipt and restricted delivery services are available for additional fees. Registered mail should only be used when you want to insure your mail and send it first class. To use registered mail it must be brought to the Mail Center to be posted and taped up. Registered mail requires every seam be covered with paper tape and daubbed by the U. S. Post Office.
