What is a valid phone number for Hong Kong?

Answer 1

Hong Kong uses telephone country code +852. Most numbers have 8 further digits. Landline numbers mostly begin with 2 or 3; mobile numbers mostly begin with 5, 6, or 9; pager numbers begin with 7; and forwarding services and VoIP begin with 8.

Thus, any number beginning with +852, with the next digit 2, 3, 5, 6, 7, 8, or 9, with 7 digits after that, is a potentially valid number in Hong Kong.

(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, Japan uses 010, Australia uses 0011, and many other countries use different prefixes.)
