Do Not Open Mail if Your Name Is Not on the Address

Please ensure that the mail seal is undamaged. If the package is opened, its content can no longer be considered private. You may have to pay for the postage if the mail is damaged or requires repackaging.

Don’t Forget to Highlight the Reason

Place “Return to Address—Unknown to sender, or Misdelivered, or Refused” on the package’s envelope. This will help the postal worker better understand why the mail was not accepted. By doing this, you can prevent re-attempts to your address and ensure the message is delivered to the right place.

Reasons to Return to Sender Auspost

There are several reasons for customers to send back mail items, including:

Misdelivery by the Post Office to an Incorrect Address

Sometimes, you may get an envelope or package in your mailbox that belongs to a different address. It is known as misdelivery and is a manual mistake by the postal carrier. In such cases, it is helpful to know how to return mail to the sender via Australia Post.

The reason could be a misinterpretation of the address, which is why the Post Office always asks customers to mention their addresses in the correct format. Nevertheless, misdelivered mail is not your fault, and you can return to the sender, Auspost effortlessly. Just place the item back in the mailbox or hand it to the carrier the next time they comes to your doorstep.

In this case, you need not go anywhere or repack anything to return to the sender, Auspost. The delivery person will take the mail piece back and do the needful.

Mail Addressed to Old Residents

It happens more often than we would like because many people forget to update their new address with the mail carrier. Moreover, they also skip informing senders that their address has changed. Therefore, you may need to return to sender Aupost for a while.

Understanding how to return to sender Australia can help you prevent this situation. All you need to do is mark the item as ‘Return to Sender – Unknown At This Address’ and place it back in the mailbox. Please don’t forget to erect the red flag to tell the delivery person that an outgoing mail piece is waiting for them.

Spam Mail

Another reason you may want to return to sender Aupost is junk mail. Here, the address and addressee are both correct, but you wish to stop getting mail from a specific sender completely.

The best thing to do is to place an ‘Addressed Mail Only’ or ‘No Junk Mail’ sign on your mailbox. It helps the delivery person know that you don’t want advertising mail.

Yet, you must know how to return mail to the sender, Australia Post, using their return address. If you still get spam mail and want to return it, write down ‘Refused’ and place it back in the mailbox.

However, you cannot return to the sender, Auspost, if you have already opened the item. If you tamper with the pieces, you need to repackage them and pay the return postage.
