What Is Certified Mail? - US Global Mail
www.usglobalmail.com › what-is-certified-mailSep 19, 2020 · What Happens to Certified Mail That Is Not Delivered? The first delivery attempt of your Certified Mail will happen within three to five days. At this point, if there isn’t anyone to sign for the package, parcel, or letter, the United States Postal Service carrier will pop a notice (PS Form 3859) through your door. This states that you have a Certified Mail item waiting to be received at your nearest Post Office.
