Telephone Numbers in Hong Kong - 1970s

1970s

In the 1970s, area codes were assigned with the following pattern:

• 3 Kowloon, New Kowloon and Sai Kung
• 5 Hong Kong Island and Outlying Islands
• 12 New Territories

There was no standard trunk prefix like '0' – only the area code and phone number were dialed when calling from one area code to another. Thus the Kowloon number xxx-xxx would have been dialed as follows:

• xxx-xxx – from within Kowloon
• 3 xxx-xxx – from Hong Kong Island or New Territories
• +852 3 xxx-xxx – from overseas
