Why is the annual inspection passed but cannot be queried on 12123?

First, check whether there is any problem with your app installation or the input of registration information. If there is no problem, you can go to the traffic police department for help with the query. Documents required for annual inspection: Original ID card and front and back copies of the ID card; the front and back pages of the vehicle's driving license; the copy of compulsory traffic insurance, vehicle and vessel tax payment certificate; the motor vehicle for annual inspection. The role of annual inspection: The annual inspection of a car is to test the performance of the car to see if its performance is still sufficient for safe driving on the road. For example, some cars, although not old, cannot be driven on the road due to poor performance caused by the owner's lack of care or major unrepaired accidents.
