After the license plate is issued, you can directly proceed with the registration. Complete the registration and binding of the vehicle information on the owner's I23 APP. Generally, the 12123 registration review takes 7 working days, depending on the number of applicants. There is no specific time limit for licensing a new car. The temporary mobile permit is valid for 30 days. The maximum cycle from purchasing a new car to its official launch is generally 3 months.

I just completed the new car registration process, and the staff at the vehicle management office told me that as long as I have the vehicle license and registration certificate, I can go through the modification filing procedure anytime. For example, changing the body color or replacing the engine doesn’t require waiting for any time limit. Last week, my neighbor went to file for a color change the day after picking up the car. With all the required documents—ID card, vehicle registration certificate (big green book), and vehicle license—it only took half an hour to complete. However, it’s best to check local regulations before making modifications, as some areas prohibit changes like exhaust system modifications, which won’t pass the filing process. Also, remember to clear any traffic violation records beforehand, or the vehicle management office won’t accept the application.

As someone who frequently helps friends with vehicle-related matters, there's actually no fixed time limit for new car registration. Last month when I helped my cousin with the transfer process, I specifically asked at the counter and they clearly stated that as long as all registration documents are complete, you can even register and file for record on the same day. The key is to prepare materials like vehicle photos and modification certificates in advance, while ensuring all modifications are within legal limits. Once I saw a car owner who applied full-body reflective film, only to be told it couldn't be registered, making the trip pointless. I recommend checking the official DMV website for the required document checklist beforehand to avoid unnecessary back-and-forth trips.

We just discussed this in our car club group chat. A seasoned modder shared his experience: he went to file the modification for his audio system on the same day it was installed. The DMV mainly checks two things: first, whether all required documents are complete, and second, whether the modifications comply with national standards. There's no need to wait—the sooner you file, the better, otherwise you might run into issues during the annual inspection. Last time I modified my wheel size, I went to file it the following week, and the officer just flipped through the registration certificate before processing it. But remember to take photos as proof before making any modifications, as the DMV will compare them to the original factory condition.

The other day, I went to the DMV to renew my driver's license and specifically inquired about the new vehicle modification registration window. The staff explained that there's no legal requirement to wait several days before registering modifications—you can apply for changes as soon as the initial registration is completed. However, they reminded me of three key points: Engine modifications require providing qualification certificates; body color changes exceeding 30% must be registered; illegal modifications will be required to be reverted. Registering modifications immediately after getting license plates is perfectly fine—my colleague did this when modifying his grille, just bring basic materials like the vehicle purchase invoice.
