The car is going to be licensed. Why doesn't the traffic control department send a message to the owner?

Because the database of traffic control 12 123 has not been updated.

Because the database of traffic control 12 123 has not been updated, the data after licensing is still in the vehicle management office, and it is not synchronized to the database of traffic control 12 123, so the information of licensing cannot be seen in the system.

Documents required for licensing: ID card, automobile certificate, automobile parameter list, automobile invoices 2 and 4, automobile purchase tax, automobile insurance policy, etc. : car purchase invoice, vehicle certificate, invoice ID card or organization code certificate and its copy, compulsory insurance policy, tax payment certificate and temporary residence permit for foreigners.
