If your certified letter has been accepted and is being tracked by the postal service, you might want to give it some extra time. If all goes well, your letter will be delivered within 10 days. If the recipient is not home, the letter will get returned to the local post office. The Post Office is not required to make delivery on Certified Mail letters; their obligation is to try and make delivery. If no one answers the door, they place a sticker (ps form xxx) on the door or in the mail box letting the recipient know that a certified letter is at the post office for them to pick up.
