Legal analysis: it can still be used within the validity period, and the old ID card will not be covered after the new ID card is reissued. Because the current second-generation ID card has no password function, you can't stop using the card by changing the password. So the lost ID card can still be used within the validity period. The Ministry of Public Security has started the registration of fingerprint information of resident identity cards and taken various measures to ensure the safety and reliability of resident identity cards. To prevent identity cards from being stolen after being lost to the maximum extent. When residents reissue their ID cards, the ID number remains unchanged, and the information such as the address inside is generally unchanged. The only change is the date of issuance of the document. When conducting inspection, the public security organ may determine that the old certificate is invalid and the new certificate is valid. However, this identification is limited to the system of public security organs. When banks handle business, stay in hotels and surf the Internet in Internet cafes, the system still judges the old card as "true and valid".
Legal basis: Article 5 of the Law of the People's Republic of China on Resident Identity Cards. The validity period of the resident identity card of citizens over the age of 16 is divided into ten years, twenty years and long term. Sixteen to twenty-five years old, issued a resident identity card valid for ten years; Twenty-six to forty-five years old, issued a valid identity card for twenty years; People over 46 will be issued with long-term valid identity cards. Citizens under the age of sixteen who voluntarily apply for a resident identity card shall be issued a resident identity card valid for five years.
