About Hong Kong Calling Code
Hong Kong's international dialing code is +852. This code is assigned by the International Telecommunication Union (ITU) and must be dialed before the local phone number when calling Hong Kong from another country. Hong Kong is located in Asia.
Hong Kong is known locally as ้ฆๆธฏ โ Hong Kong is the capital. When saving an international contact, write the number in full international format with +852 so it works from any country.
Country calling codes (also known as ISD codes or dialing codes) are telephone numbering plan prefixes defined by ITU-T standards E.123 and E.164. Each country is assigned one or more unique prefixes to facilitate international direct dialing.
Where the +852 Calling Code Is Used
The country code +852 is assigned to Hong Kong, located in Eastern Asia, with the capital Hong Kong. This code is part of the international telephony numbering plan and is used for all calls made to Hong Kong from outside the country.
When you see a phone number written as +852 ..., the +852 prefix tells your telephone network to route the call to Hong Kong's national telephone network. After the country code, you dial the local area code (dropping any leading 0) and the subscriber number. The same format applies whether you are calling a landline or a mobile phone.
Country codes are allocated by the International Telecommunication Union (ITU-T Recommendation E.164) and are grouped by geographic region. Calling codes starting with 8 are generally assigned to the region around Hong Kong, in Eastern Asia. When a phone number is stored internationally, the leading zeros of the domestic area code are omitted after the country code โ this is why you will often see numbers written as +852 followed directly by the area code and number.
Hong Kong Phone Number Formats
Phone numbers in Hong Kong follow the ITU E.164 international format: country code + area code + subscriber number. Below is the general structure used for both landlines and mobile numbers.
๐ฑ Number Structure
- International format: +852 [area code] [subscriber number]
- From abroad: exit code + +852 + local number (drop the trunk prefix 0)
- Within Hong Kong: dial the local number directly
Most countries use a closed or open telephone numbering plan. In an open plan, the length of local numbers varies and the trunk prefix (usually 0) is dropped when dialing internationally. In a closed plan, all national numbers have a fixed length regardless of area. When dialing Hong Kong from abroad, always replace the leading trunk zero with the country code +852.
Time Zone in Hong Kong
Hong Kong is in the Asia/Hong_Kong time zone, which is UTC+08:00 relative to Coordinated Universal Time (UTC). If you are calling from a different time zone, remember to account for the time difference when scheduling your international call.
When planning a call to Hong Kong, the time difference matters: a good time to reach businesses in Hong Kong, the capital, during their working hours may be early morning or late evening in your own time zone. Many international callers use the UTC offset as a quick reference to avoid calling in the middle of the night.
Some countries observe daylight saving time (DST), which shifts the local clock by one hour during summer months. If Hong Kong uses DST, the effective offset changes twice a year โ check the current UTC offset before dialing if your call is time-sensitive. For most purposes, however, the standard offset shown above is sufficient.
