I ordered a package through Amazon on April 9th, 2017 and was given the tracking number:
89195421321
When I check the status, it says that it is "invalid and cannot be tracked". I am leaving on a business trip in a few days and would like to know when I will receive my package. Thank you.

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?
