Opinions of the Ministry of Public Security on Comprehensive Answers to Relevant Issues Concerning the Replacement of Lost Resident Identity Cards: When citizens apply for replacement of their identity cards, they also inform the public security organs of the fact that they have lost their identity cards, and there is no need to apply for "reporting the loss" or making a newspaper statement, and there is no relevant law stipulating that citizens need to apply for "reporting the loss" or making a newspaper statement after losing their identity cards. Resident identity card is the legal identity document of citizens, and its main function is to prove their identity when they engage in related activities. When a citizen uses a resident identity card to prove his identity, all relevant departments have the obligation to check the consistency of the witness card, and can handle relevant business for the holder only after it is confirmed to be correct. If a resident's ID card is lost and is fraudulently used by others, the fraudulent user and the relevant departments should bear corresponding legal responsibilities, and the person who lost the ID card is not responsible for the behavior that he did not implement.
The Law on Resident Identity Cards also clearly stipulates that anyone who fraudulently uses another person's resident identity card shall be fined between 200 yuan and 1,000 yuan by the public security organ or detained for less than 10 days. If there are illegal gains, the illegal gains shall be confiscated.
