You can't find the sender by using the tracking number. At best you may be able to find out the city it was sent from. Your best bet is to contact the post office and ask who sent it.

Not always. It can be though. ------------------ certified mail has nothing to do with the contents. It means the sender wants the delivery and receipt of the mail verified b the the U.S. Post Office. Sometimes certified mail is good news sometimes it is bad news.

Just ask the Letter Carrier or Sales Associate, there is no rule that says they can't. Remember the Postal Service is all about Customer Service.
Certified mail is mail that is designed to ensure it gets to its proper recipient. Generally when someone sends a certified letter, he wants to ensure that it gets to the recipient and a receipt signed by the recipient at the time the letter was delivered is sent back to the sender, giving the sender a record that such mail has been delivered.

If a person is not home to sign for a certified letter, a notice will be lift at their home. A person has 7 days to pick up the letter, before the post office will try again. Two more attempts will be made, before it will be returned to the sender.
Certified mail is a way to mail a letter and receive a tracking number that allows you to know when it was delivered. For an additional fee you may also request a signed delivery slip from the recipient which allows you to prove that they got the letter. This is very helpful when the person is trying to avoid you. The post office makes two attempts and documents notification to that person that they have this letter for them. The third time the post man can't deliver they get a notice that the letter is at the post office waiting for them to pick it up. If the person has a post office box they still get this notice and have to sign for it. You can even request that the person show id to get it. If the post office is unable to deliver certified mail, it is returned unopened to the original sender, as further proof and record of the attempts to send it. In many court cases, the mere fact that a person has been sent a certified letter to their last known address is sufficient proof that they have been "officially notified" of whatever was in the letter.
