Kuwaiti identity card
The Kuwaiti identity card is issued to Kuwaiti citizens and residents. It can be used as a travel document when visiting countries in the Gulf Cooperation Council.
The Kuwaiti identity card (K-1) is an identity document issued by the Government of Kuwait. It is an official identification card issued by the central authority body and contains personal information, such as name, gender, place of domicile, security issues, and other details which are related to a citizen in his/her natural life. People who are over 18 years of age are eligible to apply for their own K-1 cards.
As of 2019, expats have to use their civil ID instead of residency sticker at airports or borders. You can check Civil ID status in Kuwait
