Well, it really depends. It's also possible that the tracking info hasn't been updated by the courier. You can try to contact your local postal service courier or the sender and ask for help!

Same problem with mine UR449698504CN
I think the UR series tracking of early May 2019 has been either affected or something gone wrong
Tracking results ends at "Arrived at sorting centre"
Mine has been at Ningbo for the last 1 month. Seller claims it left china but there is no indication that it even reached Beijing in the first place. Tracking information not available in the UPU global track trace. Still waiting
