Notes

  • Status codes: ZTO's codes are mapped (4 out for delivery, 5 and 15 delivered, 16 left with an agent or at a pickup point as exception; warehouse, flight, ship, line-haul and customs codes are in_transit). code carries ZTO's own number.
  • English wording only: descriptions are ZTO's English lines; the Chinese text is not used because it carries couriers' phone numbers.
  • Time zone: scans start abroad (Korea, Japan, US, Hong Kong...) and end in China, so there is no single zone; only localTime is set.
  • Batches: several numbers go to ZTO in one request.
  • How it is queried: the applet API behind m.ztoglobal.com, sent as that page sends it, which answers without a captcha code.
