Hong Kong has no postal code at all, so delivery leans entirely on the region, district, building, and floor. Forms that require a postcode field, or that omit the floor and flat, are the usual cause of failed delivery. Here is the format and how to validate it.
A Hong Kong label is recipient, the flat, floor, building and street, the district, then the region, then the country. There is no postal code.

Routing depends on the region (Hong Kong Island, Kowloon, or the New Territories), the district, and the precise building, floor, and flat.
The country-specific rules that generic autocomplete and single-line address fields tend to get wrong.
Unlike almost every other market, Hong Kong uses no postal code. A checkout that makes the postcode field mandatory will block or corrupt Hong Kong addresses, so it should be optional or hidden.
Addresses are vertical: the floor (12/F) and flat (Flat 5) are as important as the street. In dense high-rises, a missing floor or flat means the parcel cannot be delivered.
Hong Kong splits into Hong Kong Island, Kowloon, and the New Territories. Naming the region, then the district (Central, Mong Kok), keeps the address unambiguous.
Addresses are commonly written in English or Chinese. Keep one language consistent on a label rather than mixing partial translations.
Each of these passes a basic "is this field filled in" check but fails at the carrier, turning into a redelivery, a return, or an address correction fee.
How the major carriers handle Hong Kong addresses, and what your label needs to satisfy each one.
The public postal operator. With no postal code, it routes on the region, district, building, floor, and flat, so those must all be present.
Major private carriers for Hong Kong ecommerce. They rely on precise building, floor, and flat details for vertical last-mile delivery.
International carriers for inbound shipments. Include the destination line; a complete building, floor, and flat avoid redelivery.
