Hello dear ~ I'm glad to answer this question for you. Dear, change the date of birth without relevant certificates: Step 1, the person who changed the person's age submitted a written application to the local police station to change the date of birth from the original date of birth to the date of birth. The applicant's autograph, seal or handprint are also required. The second step is to find relevant evidence. This is complicated and difficult to find, but these must also be provided to the police station. General materials, such as early handwritten household registration books and census registers. If there is no basis, the police station will not accept the third step. The community (village) police will take the lead, and 5- 10 people, including community (village) cadres, the applicant's neighbors (must be non-close relatives) and the midwife at that time, will attend the hearing meeting. At the meeting, each participant needs to bring his/her ID card, and make a statement and hearing about the applicant's real birth. After the participants confirm their signatures, they can change the age of the applicants. Step 4: After the police in the jurisdiction bring the hearing materials, application materials and evidence materials to the leaders for approval, the household registration personnel will modify the date of birth of the applicant's household registration online. Step 5: After the date of birth of the online system of the police station is changed, the police station will notify the applicant by phone. Bring the household registration book and the original ID card to the household registration window of the police station to reprint the household registration page and apply for a new second-generation ID card. Step 6: After getting a new ID card, the applicant needs to change the basic information of the system in financial institutions and relevant departments such as banks, insurance and social security. Every time the company changes the information, it needs to issue a certificate to the police station that the original ID number and the current ID number are the same person, and the relevant units will change the basic information for you.
