The Oregon Certificate of Mailing Report is a form used to certify that a document has been sent by mail. It is used to prove to a court or other authority that a document was sent on a certain date. There are two types of Oregon Certificate of Mailing Report: the regular and the certified. The regular Certificate of Mailing Report is used when the sender wants to certify that a document was sent by mail but does not need to provide proof of delivery. The certified Certificate of Mailing Report is used when the sender wishes to provide proof that the document was delivered to the intended recipient. This type of certificate requires that the sender pay an extra fee to the postal service in order to receive a return receipt. Both types of certificates must be completed correctly and signed by the sender, and include the name and address of the recipient, the date of mailing, and the types of documents being sent.
