I handled the annual vehicle inspection at 12 123, but I don't know if I have written the postal address. What should I do?

Generally, if the application is successful, there will be an option, whether to pick up the annual inspection label yourself or express delivery. If you choose express mail, there will be a delivery address for you to fill in, and the express mail will be delivered to you within one week after submission. Now you can log in to the Traffic Management Office 12 123 to check the online operation progress at the bottom of the home page, or you can consult the local vehicle management office.
