Ordered a package on april 18th to be shipped to US, was sent tracking info in a timely manner, it says its been received at my local post office as of yesterday evening. I called the post office branch to see when it'd be delivered because it's not showing up on my dashboard for usps registered mail but another package I'm expecting is. How do we find my package as they say it's not there & they cant even find it with the China Post tracking information I was sent???? Tracking # is AS014830877CN.
Thanks!

I was expecting the package from China to US with the tracking number provided as UF529387457YP. The sender happens to write the wrong address, and I would need to contact the US post office to set up new delivery address. However, when I provided this tracking number to US post office, they could not locate anything. It seems that it is a tracking number in China post system, but not the US one. Would you please advise what is the corresponding USPS tracking number for UF529387457YP? Thank you!

Seller claims to have shipped my package (tracking #LW239379810CN), but tracking status remained as "A tracking number was provided" for several days now on the selling platform. I contacted seller, and he claims that he has contacted the logistics company (China Post) and that they told him it arrived at the airport and will update soon. It's strange, since I've tried tracking this package on the actual China post website, and there's no update, yet the seller is able to find out "where" it is. I think the seller is lying. Someone help.
