YF Express tracking numbers have no shape of their own, so always pass ?carrier=yfexpress.

Notes

  • Scan wording: Chinese for the Chinese leg, the destination post's wording for the rest.
  • Time zone: scan times come with no zone, so localTime is each scan's own clock time and timestamp and deliveredAt are null.
  • Batches: up to 20 numbers go to YF Express in one request.
  • Platform: YF Express runs the Hualei (华磊) tracker, shared with JYExpress and other Chinese forwarders.
