This may not be related to China Post, but I'm not sure where to find more information so I'm asking here in case someone knows.

I ordered something from Gearbest (I think they are based somewhere in GuangDong province or have office in Hong Kong too). I used expedited shipping "DHL(AT)".

A few days later, Gearbest gives me this kind of temporary tracking number for my shipping info:

"AT15284524278714"

In my prior experience, that temporary number will later change to a real DHL tracking number (and usually it will originate from Hong Kong, though a few times from GuangDong).

However, just recently, I notice a tracking website is actually able to provide a bit of information for the above tracking number.

I have tried many other tracking websites for the "AT15284524278714" -- but the above website seems to be the only one that provides a little bit of information.

question: Anybody have more information or guess as to what courier is actually used?

(I recall Gearbest also uses Sky56.cn to ship packages)
