Senders are required to provide a local mobile phone number that can receive SMS, so that if necessary they can receive messages issued by Hongkong Post on the requests by overseas customs authorities related to customs clearance of the mail items and take follow up actions. Hongkong Post will not embed hyperlinks in the related SMS requesting for any personal information. Members of the public could contact Hongkong Post enquiry hotline 2921 2222 direct if they have any doubts on the SMS received. For details, please click here.
