I have been expecting a package tracking number UI029812836CN. The last thing I see is that it made to Level Two processing. My question is, why is it no longer trackable. If you sent it through one carrier and another carrier takes over it. Why didn't the customer get that tracking number.

I wonder if someone could please tell me if the parcel ZA00134444401 has been handed over to a different carrier yet? if not, which carrier is going to deliver my parcel to me?
I've tried to track multiple carrier websites but no luck with this tracking number.
It's a parcel going to the Netherlands :)

My tracking status says

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.

Does this mean my package is lost?
