Technical info on H.K. phone numbers

  • Hong Kong phone numbers are regulated by the Office of the Communications Authority (OFCA) and follow a specific structure and format. Due to its small size and high population density, Hong Kong doesn't use area codes like many other countries.
  • Country code: The country code for Hong Kong is +852. When dialing a Hong Kong phone number from abroad, you need to use this code followed by the local number.
  • Number format: Hong Kong phone numbers generally have 8 digits. The format can be written as XXXX YYYY, where X and Y represent digits. As mentioned earlier, there are no area codes in Hong Kong, as the numbers are allocated directly to subscribers.
  • Number types:
  • Landline: Hong Kong landline numbers usually begin with the digits 2 or 3, followed by seven more digits.
  • Mobile: Mobile phone numbers in Hong Kong generally start with the digits 4, 5, 6, 7, 8, or 9, followed by seven more digits.
  • Non-geographic numbers: These numbers are not tied to a specific location and can be used for various services like toll-free, premium rate, and VoIP services. Non-geographic numbers usually start with 70 or 80.
  • Special numbers:
  • Emergency services: The emergency phone number for police, fire, and ambulance services in Hong Kong is 999.
  • Directory inquiries: To access local directory assistance, you can dial 1081.
  • Dialing within Hong Kong: When dialing a local number within Hong Kong, you simply dial the 8-digit number without the country code. For example, if you want to call a landline number 2123 4567, you would just dial 2123 4567.
  • Dialing from abroad: To call a Hong Kong number from outside Hong Kong, you need to dial your country's international exit code, followed by the Hong Kong country code (+852), and then the 8-digit local number. For example, if you are calling from the United States, you would dial 011 852 2123 4567.
  • Dialing to another country: To call a foreign number from Hong Kong, dial the international access code (001), followed by the destination country code, area code (if applicable), and local number.

The history behind Hong Kong phone numbers

  • Early beginnings (1920s-1960s): The first telephone exchange in Hong Kong was established in 1925, with the introduction of manual switchboard systems. Telephone numbers during this period were relatively short, consisting of 4 or 5 digits.
  • Introduction of automatic exchanges (1960s-1980s): As the city's population grew and the demand for telephone services increased, Hong Kong started to adopt automatic exchanges. This led to the gradual phasing out of manual switchboards. During this period, the length of phone numbers increased to 6 digits.
  • Area codes and further expansion (1980s-1990s): To accommodate the growing demand for phone numbers, Hong Kong introduced area codes in the 1980s. The area codes were added as a prefix to the existing 6-digit numbers, creating 7-digit numbers. The most common area code was "2" for Hong Kong Island, "3" for Kowloon, and "4" for the New Territories.
  • Transition to 8-digit numbers (1995 onwards): In 1995, Hong Kong transitioned to an 8-digit numbering plan. This was done by adding a digit in front of the existing 7-digit numbers. For example, numbers in Hong Kong Island with the area code "2" became "28X-XXXX", while those in Kowloon with the area code "3" became "23X-XXXX". The change was implemented to accommodate the rapid growth of the city and the increasing demand for phone numbers, especially with the proliferation of mobile phones and fax lines.
  • Introduction of mobile phone numbers (1990s onwards): With the advent of mobile phones, a new set of prefixes was introduced to differentiate between landline and mobile numbers. Mobile phone numbers in Hong Kong typically start with "5", "6", "9", or more recently "4" and "7".
  • Number portability and VoIP services (2000s onwards): Number portability was introduced in Hong Kong in the early 2000s, allowing users to keep their phone numbers when switching between service providers. This facilitated competition in the telecommunications market. Additionally, the rise of Voice over Internet Protocol (VoIP) services led to the introduction of new number ranges, such as those starting with "3".
