What is the maximum validity period of a temporary license plate?

[StevenAnn]

Temporary license plates have a maximum validity period of 90 days. A temporary license plate is a provisional vehicle travel certificate issued by the vehicle management department of public security authorities when a car has not yet been officially registered due to certain procedures being processed. Temporary license plates are divided into: 1. Temporary license plates for administrative jurisdictions; 2. Temporary license plates for cross-administrative jurisdictions; 3. Temporary license plates for testing purposes; 4. Temporary license plates for special-type motor vehicles. The materials required to apply for a temporary license plate include: 1. Identity documents of the vehicle owner and the agent; 2. Proof of the vehicle's origin; 3. The whole vehicle factory qualification certificate for domestically produced motor vehicles, or the import certificate for imported motor vehicles; 4. The vehicle identification code and engine number rubbing. There are two temporary license plates in total, one to be affixed to the lower left or right corner of the front windshield, and the other to the lower left corner of the rear windshield.
