Calling Hong Kong from United States: what to know

Hong Kong answers on the country code +852, with the capital in Hong Kong (special administrative region) and most business concentrated around Landline and Mobile. The working language for business is Cantonese and English, and local offices generally keep hours of 09:00 to 18:00, Monday to Friday, with Saturday mornings still common.

From United States the outbound access code is 011, so a manual dial reads 011 then +852 then the local number. StartACall removes that step: the call goes through your browser, so there is nothing to install and no SIM card to swap when you travel between United States and Hong Kong.

Most mobiles in Hong Kong sit on operators such as CSL, SmarTone, China Mobile Hong Kong. Hong Kong uses a flat 8 digit plan with no area codes; landlines start 2 or 3 and mobiles start 5, 6 or 9.

Hong Kong runs on UTC plus 8, and it does not observe daylight saving, so the time difference stays constant through the year.
