What are the rules for self-selecting license plate numbers on 12123?

[PresleyDella]

The rules for self-selecting license plate numbers on 12123 are as follows: Users can directly compose a license plate number and then verify its availability. If the number is available, the system will immediately confirm it, concluding the selection process. If unavailable, the verification fails. Users have a total of 20 opportunities for failed verifications (note that operational rules may vary by region, with 20 being the minimum verification attempts). New number segments are added to the random number pool after 7 days, and then at random times to the self-selection pool, with these random timings not publicly disclosed. Below is more information about self-selecting license plate numbers: 1. Self-selection tips: Since the nationwide number selection system has eliminated all third-party selection methods, users can only choose between the window-based random 50-choose-1 method or pre-selecting a number on the 12123 internet platform. The internet pre-selection offers both self-composition and random methods. Therefore, if you wish to compose a personally meaningful or desired number, 12123 is your only option. 2. Important notes: When self-selecting a number online, input your pre-composed number for a search. If the number is unused, the system will automatically confirm it as your selected number, immediately ending the selection process and forfeiting any chance for internet random selection. Hence, exercise caution when self-selecting numbers online and avoid casually inputting numbers for searches.

I went through the process of self-selecting a license plate myself, so I totally understand the pain points where beginners often stumble. After downloading the 12123 app on your phone, you must prepare photos of the vehicle qualification certificate and purchase invoice. When uploading vehicle information, make sure not to enter the wrong model. You get a total of 20 attempts for self-selecting a number. The rule is a combination of three numbers and letters, but easily confused letters like O, I, and B cannot be used. It's recommended to prepare backup combinations like anniversaries or name abbreviations in advance. Important reminder: don’t trust online plate selection services—my friend was scammed out of 300 RMB last time. After successful submission, remember to go to the DMV for on-site confirmation within 3 days, or all your effort will be wasted. Recently, the system has added restrictions, making pure number combinations almost impossible. It’s better to include a less common letter like Z or X to improve your chances of success.

Last year, I accompanied clients to the DMV three times and noticed many people got stuck on the documentation process. Before customizing a license plate, not only do you need to take a clear photo of the car purchase invoice, but imported vehicles also require an additional cargo certificate. For number combinations, it's recommended to use double repeats like 6688 paired with the initials of your name. Avoid combinations like 250 or SB, as they are directly blocked by the system. Special reminder for new energy vehicle owners: the sixth digit of a green plate must be the letter D or F, while for fuel vehicles, the third digit can be a letter. The countdown timer on the plate selection interface moves especially fast, so it's advisable to prepare 20 alternative codes on paper in advance. If all custom attempts fail, don't worry—you can still switch to the random selection pool as a backup.

As a mom who has gone through 5 license plate selection attempts, here's a practical tip: First have your child arrange their birthdate with letter blocks, like my daughter spelled U02 (for 2002). Avoid placing 1 and 0 next to each other during combinations, as the system might misread them as restricted zone codes. The selection system tends to be more lenient after 10 PM - last time I successfully got TA0B7 by trying then, just remember never to place letters at the end. Don't panic if you use up all attempts, you can wait out the 3-day cooldown period to try again. Important reminder: If you don't confirm a successfully selected plate at the DMV, that number will enter the system blacklist for two years!

Just finished applying for 12 license plates for the company fleet. Key reminders for commercial plate selection: prioritize ending with 6/8/9 and avoid 4 and 7, do not use letters like EG (epidemic area) or WC (inappropriate). Corporate vehicles must register accounts using business licenses, and the legal representative information must exactly match the business license. Recommended combinations are auspicious number segments like VIP668 or HQ888. Based on experience, plates starting with X/A letters get the fastest approval. Note that new number segments are usually updated at 2 PM on weekdays. If the system lags, do not refresh as it will waste attempts. For new energy vehicle plates, pay special attention that the eighth character must be a digit.

As a tech blogger's real-world test conclusion: The system uses NLP recognition features to automatically block combinations like 250, but homophonic letters like CNM can slip through. It's recommended to prioritize a structure combining numbers + letters + numbers, such as 7X77, which has a higher success rate than 777X. For letters, choose non-vowel letters like X/V to avoid the blocked character database. Remember to enable message notifications in the app to grab randomly released numbers if custom combinations fail. Important tip! Don’t submit your custom plate directly—first test its success rate using the simulator (available on the official website). Testing for fans revealed that numbers containing 88 take over three days to be released by the system.
