Write a name change application to the police station where the household registration is located, stamp it and register with the household registration unit of the local public security bureau, and of course bring the household registration book. It can be formally changed in about 15 or 7 working days after submission of documents. What was your name before, and what is your name now will be written in the household registration book. When you need a diploma or something to prove your identity, you must bring your household registration book. The specific procedure is: the person who wants to change his name goes to the household registration window of the public security bureau where the household registration is located, receives the application form, provides the required information, and can change his name after approval. In addition, the landlord should be reminded that the name change must be cautious, because the name change will involve a series of problems such as his bank card, social security, medical insurance and property right certificate. If it is not handled well, it will also cause a lot of trouble.
