My tracking status hasn't changed since about a month and 2-3 days after the last update (in Transit) there was a notification saying

Not Found
This number can't be found at this moment. It's not available in the carrier's system yet. Please check back later. This may due to several reasons:
The item has not yet been accepted by the carrier.
The item has not yet been entered in the carrier's system.
Your tracking number is incorrect or invalid.
The item was posted a long time ago, info not available anymore.
Generally, after the item has been sent, it will be processed and enter tracking information by the carrier. There might be a delay between these scanning events and tracking availability the carrier's system. Usually it takes a few days for processing, therefore the tracking information may not appear online immediately, please try to track again later.

Will I ever actually receive the parcel or is it lost and gone forever?

Hello I have a package that’s over a year old at this point. I know I have been told it’s lost. I was just curious if a lost package can ever be found or is it lost forever? Like is there any chance it could be found and continue its trip in the mail system to the US or since the tracking number is so old of it was ever found it would not scan? Does this question make sense? Thank you for the help. The tracking number I was given is LS330562095CN
