You need ID information after joining the company. In order to avoid trouble, the ID card shall prevail. For example, the company's birthday activities are based on the age of employees' ID cards.

If the age of the ID card does not match the actual age, you can apply to the local police station where the permanent residence is located to change the age of the ID card. However, because changing age involves many interests, there must be authoritative original evidence, such as birth certificate or original household registration information. The applicant or guardian shall submit an application to the local police station with relevant materials, and the police station shall report it for approval step by step.
