How to call Hong Kong from abroad
The first digit tells you what the number is: 2 and 3 are mostly landlines, while 5, 6 and 9 are mostly mobiles. Hong Kong shares its code with no other place, so +852 always means Hong Kong.
Mobile numbers: Mobiles have 8 digits with no 0 or area code in front, and sit mostly in the 5, 6 and 9 ranges, so a mobile looks like +852 9xxx xxxx. An example in international format: +852 9xxx xxxx.
Calling out of Hong Kong. From a landline there, start with 001, then the other country's code and number. From a mobile, + works everywhere.
Time in Hong Kong. Hong Kong is on GMT+8 all year. Check the time before you call, especially for business numbers.
Numbers starting 800 are freephone with 9 digits, and 900 information lines can be up to 11 digits.
Hong Kong's main international exit code is 001, but carriers also run their own, from 0030 to 009, so dialling out is not always 00.
The official plan reserves every 74x to 79x block for a future move to longer numbers.
Missed call from +852?
Hong Kong's Office of the Communications Authority (OFCA) announced in April 2023 that mobile networks would warn customers when a call shows a +852 prefix, with the alert "Call is from outside Hong Kong. Beware of deception." This is aimed at people in Hong Kong who receive fake local-looking calls.
