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

[JulianLee]

You should file a record with the vehicle management office at the place where the driver's license was issued within thirty days after the information changes. The materials required for driver's license information changes include: 1. Original application form: Original "Motor Vehicle Driver's License Change Application Form". 2. Original identity proof: Original and photocopy of the motor vehicle driver's identity proof (non-local residents need a valid residence permit and photocopy). 3. Driver's license: Original motor vehicle driver's license. 4. Household register: If the driver's name or "Resident ID Card" number changes, a household register and relevant proof issued by the local public security authority are also required. 5. Photos: Three recent front-facing, bareheaded, white-background color ID photos.
