Received a message from our post office here in the U.S. saying "USPS CP333771623CN, Processed thru Facility 03/16/2017 2:36pm SHANGHAI CHINA USPS Tracking Number Invalid - YES
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.
There is no tracking information for it at present. Possible reason is the sender just gave you a tracking number but hasn't shipped it.
You'd better contact the seller to confirm for the reason.
