I replaced my license plate on the 12123 platform, and the entire process took about 10 to 15 days. The review was approved the next day at the earliest, but the plate production took the longest, usually 3-5 working days. I chose to have it mailed to my home, and waiting for the delivery took another 5 days. I recommend taking multiple photos of the vehicle identification code when submitting, as last time my application was returned for re-review due to blurry photos, wasting two days. A temporary license plate will be generated simultaneously, valid for 15 days, and must be affixed to the lower left corner of the front windshield before driving, or you'll definitely be fined if stopped by traffic police. It takes longer during holidays, so it's best to apply in advance. The fee is over 100 yuan paid online, and there's an additional 12 yuan for COD delivery.

The time for license plate replacement varies, based on my experience, it could take anywhere from 7 to 20 days. The review process usually takes just one or two days, but the key factor is how busy the license plate factory is. It's not uncommon for the production cycle to exceed 5 days, especially during the peak period at the end of the month. For mailing, EMS is recommended as regular couriers may not be allowed to enter residential areas. Remember to print the temporary license plate on hard paper—I once used flimsy A4 paper and got a warning from the traffic police. With the recent rainy season, if you're worried about slow delivery, you can opt for self-pickup at the DMV to save about 3 days. After applying, the 12123 app will push daily updates on the progress, so checking the app occasionally is better than just waiting. If your temporary license plate expires, you can apply for a second one at the DMV as an emergency measure.

It took a full 14 days from application to receiving the replacement license plate last time, so annoying! The review was supposed to be completed in two days, but it dragged on until the fourth day. The production stage was the worst - the system showed 'pending production' for a whole week. The delivery was pretty fast though, arriving at the doorstep in three days. Important tips: When submitting, make sure the vehicle identification number photo isn't reflective - I had to retake it the first time due to glare. Temporary plates must be used with the same vehicle as on the registration certificate; driving another car counts as unlicensed driving. Remember to check the app status daily - it's frustrating if it suddenly changes to 'application withdrawn'. System maintenance is even more troublesome - last time an upgrade made me wait three extra days. Install the plates immediately upon receipt and tighten all four screws properly to avoid rework.
