Some websites outsides Hong Kong will ask the code for postal to Hong Kong and address of their new users registering from Hong Kong. Usually Hong Kong citizens will just leave the ‘postal code’ (aka ZIP code) field empty, or type ‘000000’ when it is a required field.
Even Hong Kong citizens provides feedback to affected websites, but webmasters ignores. Today, I heard a case that a webmaster replying a friend with a google result page about Hong Kong postal code.
Let me repeat: “It’s no such thing (Postal Code) in Hong Kong.”
According to General Addressing Issues document published by Universal Postal Union, “Hong Kong” is listed at the table of “List of countries which do **NOT** require postal codes or use a single postal code for the whole country”.
On the other hand, to be a smart international postal sender, please write “HONG KONG” only on the last line (aka country line) of your postal. Otherwise, your packages sending to buyers or receivers in Hong Kong are in risk to lost during international postal delivery.
