There may be occasions when you require information showing when and to whom a piece of mail was delivered. This information is available as an additional service with Certified Mail, Registered Mail, Express Mail, and Insured Mail. Many mailers have found that Return Receipts are utilized out of habit rather than need. If you need proof that someone received a piece of Certified Mail, Registered Mail, or Insured Mail, Return Receipt is a good way to get it. Contact Campus Mail Service for more information on Return Receipt.
