How many days should the driver's license be changed after changes occur?

[OManuel]

You should report to the vehicle management office at the place where the driver's license was issued within 30 days after the information changes. The materials required for changing the driver's license information include: 1. Original application form: original "Motor Vehicle Driver's License Change Application Form". 2. Original identity proof: original identity proof of the motor vehicle driver (a valid residence permit and its copy are required if not in the registered residence). 3. Driver's license: original motor vehicle driver's license. 4. Household register: if the driver's name or "Resident ID Card" number changes, the resident household register and relevant proof issued by the public security organ of the registered residence are also required. 5. Photos: 3 recent front-facing, bareheaded, white-background color ID photos.
