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 the rest of the world 1980s In the mid-1980s, 6 - digit numbers starting with ' 0 ' became 7 - digit numbers starting with ' 71 ', making way for subsequent change of the New Territories prefix from ' 12 ' to ' 0 '. 0xxxxx became 71xxxxx Fixed - line phone numbers were either six - or seven - digit in the 1980s. Area codes were assigned with the following patterns. 3 Kowloon, New Kowloon, Ha Kwai Chung and Sai Kung 5 Hong Kong Island and Outlying Islands 0 New Territories Cellular phone numbers are all eight - digit starting with ' 9 '. Easy dialling day On 30 December 1989, area codes were abolished. Area codes for six - digit numbers became part of subscriber 's numbers. Area codes for seven - digit numbers were simply removed. Some six - digit numbers had the first digit changed to two digits to make a seven - digit number. ( 3 ) xxx xxx became 3xx xxxx ( 3 ) 7xx xxxx became 7xx xxxx ( 5 ) xxx xxx became 5xx xxxx ( 5 ) Nxx xxxx became Nxx xxxx ( N = 8 or 9 ) ( 0 ) 8xx xxx became 46x xxxx ( 0 ) Nxx xxxx became Nxx xxxx ( N = 4 or 6 ) 1990s In the mid-1990s, a ' 2 ' was prefixed to all fixed line ( land line ) numbers which are now eight - digit. A ' 7 ' was prefixed to existing pager service numbers. xxx xxxx became 2xxx xxxx 11xx xxx became 711xx xxx 11xx xxxxx became 7xx xxxxx 9xxx xxxx remain unchanged Since 2000s Before the introduction of portable fixed line numbers, numbers were assigned in a pattern akin to districts. For example, in addition to the existing 3, 5 and 0 prefixes, a 4 prefix was used for Tuen Mun and Yuen Long, 6 for Tai Po and Sha Tin, and 8 for Island East. Numbers starting with ' 3 ' were introduced when ' 2 ' for fixed lines started running out. Cell phone numbers remain eight - digit. The number ' 6 ' started to be used when numbers started with ' 9 ' were running out. In May 2008, cellular phone numbers with ' 5 ' as the beginning were also introduced.
