The Hong Kong identity card (HKID) is an official identity document issued by the Immigration Department of Hong Kong. According to the Registration of Persons Ordinance (Cap. 177), all residents of age 11 or above who are living in Hong Kong for longer than 180 days must, within 30 days of either reaching the age of 11 or arriving in Hong Kong, register for an HKID. HKIDs contain amongst others the name of the bearer in English, and if applicable in Chinese. The HKID does not expire for the duration of residency in Hong Kong.
