Frequently asked questions
What does a Hong Kong postal tracking number look like?
International postal items use the 13-character UPU S10 format: two letters for the service, eight digits, a check digit and the country code of the sending post: HK for Hong Kong. Example: RR123456785HK.
My parcel was sent from abroad. Which post should I use?
Use the post of the country at the end of the number first. Once the item reaches Hong Kong, the destination post usually shows the same number, so you can also check it there.
Why is there no update for several days?
International mail is scanned when it leaves the origin post, at the international exchange office and again after customs in the destination country. Long gaps between these scans are normal, especially for economy mail.
Is this the official postal website?
No. TrackandTrace.com is an independent tracking directory; the tracking result comes from webapp.hongkongpost.hk.
