Generally speaking, there is no process to report the loss of identity cards, and the public security organs have not requested to report the loss of identity cards. The public security organs have no mandatory requirements for reporting the loss of resident identity cards, and all of them are voluntary. After losing your ID card, you should go to the police station to reissue it in time, and if necessary, you can report the loss in the local newspaper, which can minimize criminals from using the lost ID card to commit crimes and even cause harm to society, and also reduce the legal responsibility of the ID card.

If you find that your ID card is lost at the airport when you travel, and it is too late to apply for a valid certificate, you can bring your household registration book, work permit, driver's license, passport and other valid documents that can prove your identity to the airport terminal police station to apply for a temporary boarding certificate.
