Shenzhen traffic police didn't get the mailing address.

If the Shenzhen traffic police didn't get your mailing address, there may be the following reasons:

1. The address information you provided is incomplete or incorrect, such as postal code, address and contact person, which makes it impossible to match your mailing address correctly.

2. The address information you provided is too vague or broad. For example, you only provided a large range of information such as city or province, and you can't accurately match the specific mailing address.

Your address information is not recorded in the system of the traffic police department, so you may need to provide more information for inquiry.

If you need to let Shenzhen traffic police get your mailing address, you can provide complete and accurate mailing address information, including zip code, address, contact person, etc. If your address information is too vague or broad, you can try to provide more specific information to improve the matching degree. If you are not sure how to provide the correct mailing address information, you can consult the local traffic police department or relevant departments.
