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.
The purpose of sending a letter by certified mail is to have proof the letter was sent and received.
article 7073
There are several reasons why a person could receive a certified letter. The letter could be a bill, official paperwork such as divorce papers, etc.
For clarification, you don't type a certified letter. A letter becomes certified when you send it by USPS certified mail. This is a great way to send important documents, legal paperwork and so on, as it provides a paper trail showing when a letter was sent and when it was received.
From where it was sent
It don't always show the name of the sender.
I did not recieve a letter stating they were going to repo my jeep they said it was sent more than once but it was not sent certified
A letter should be sent "certified" to record that you actually made an attempt to contact someone at that listed address. It also guarantees someone received the letter sent. In the Medical field, where liability is of great concern, sending a certified letter shows as proof, that you made an attempt on X date, to contact X person specified, and that X person received the letter. This way, if anyone asks HOW you can prove you contacted the person, you have a receipt showing the proof.
"Certified" letter, not, necessarily.You can request a "return receipt" which will show that it was delivered to the address but not necessarily to whom.But, a "registered" letter can be sent with a "return receipt" stipulating "deliver to addressee only." Of course it will cost more for this additional service.
Certified mail requires you to sign for the mail. To know who sent the certified mail, you usually need to sign for it but the sender's name is typically listed on the green card attached to the mail. You can ask to look at the card before signing and if you miss the delivery, you can look at the slip the mail carrier leaves for you that lets you know you had a certified letter or package.
Certified notation on a business letter typically indicates that the letter has been sent via a certified mail service, providing proof of mailing and delivery. This notation often includes details such as a tracking number and the date of mailing. It assures the recipient that the correspondence is legitimate and can be tracked. Including certified notation can be important for legal, contractual, or sensitive communications.
