Calling Hong Kong from United States
Dial 011 (the United States exit code), then 852 (Hong Kong’s country code), then the local number exactly as written. So +852 2123 4567 is dialled as 011 852 2123 4567. From a mobile you can dial +852 directly instead of 011.

Step by step
Dialing Hong Kong from United States
Four steps, and the third one is where almost every failed call goes wrong.
- 1
Dial 011: the exit code for United States
011 tells the United States network that the call is leaving the country. On a mobile you can press and hold 0 to type a + instead, which works from any country and any SIM; it is the more reliable option when you travel. - 2
Dial 852: the country code for Hong Kong
852 is Hong Kong's country calling code. It never changes and is the same no matter where you are calling from. - 3
Dial the local number exactly as written
Hong Kong has no national trunk prefix, so there is nothing to remove. The number you would dial locally is the number you dial after 852. - 4
Check the local time before you dial
Hong Kong is on HKT (UTC+8, no DST) and United States is on ET (UTC−5/−4). Work out the overlap before calling; the most common cause of an unanswered international business call is simply the hour.

What is the time difference between United States and Hong Kong?
United States is on ET (UTC−5/−4) and Hong Kong is on HKT (UTC+8, no DST). Because several of these zones observe daylight saving on different dates, check the current offset rather than assuming a fixed gap.
Is it cheaper to call Hong Kong over the internet?
Usually, yes. Carrier international rates are typically far above VoIP per-minute rates, and calling from an owned local number also means the person you are calling sees a number they can ring back.
