The Postal Service encourages mailers to use return addresses because if the piece is undeliverable we can return it. The return address has the same elements as the Delivery Address and must be placed in the upper left corner of the address side or in the upper left of the addressing area.
Secondly, do you have to write your address on an envelope? The senders address isnt necessary, but it is recommended. If there are any mistakes that prevent the delivery of the letter, the lack of a return address means the post office will be unable to send it back in order to fix any problems.
Thereof, what happens if you put the same address for the return and sender on an envelope?
Most of the time the post-office will stamp a Postage Required stamp and send it to the return address. The rest of the time, they wont mind and send it to the sending address.
Where does the address go on a letter?
Your Address Place this in the upper right-hand corner of the letter in the form of: Street number and street name.
