Because Hong Kong is a small city with a dense population, it does not use postal codes.
This means that the vast majority of people can identify their own area and street without the use of a postal code.
Hong Kong's postal system began in 1841, with the establishment of the first Post Office.
Initially, just letters and parcels delivered to and from China were processed, but the service was quickly expanded to include the entire British Empire.The first postal codes were created in London in 1864.
These, however, were not utilised in Hong Kong.
In Hong Kong, the first experimental postal code system was created in 1983, but it was not effective and was quickly abandoned.There are currently no plans to implement postal codes in Hong Kong.
