Will sending express messages enter the public security system?

The information sent by express delivery may enter the public security system, but it depends on the specific situation.

In some cases, the information sent by express delivery may involve national security and criminal investigation, such as illegal activities, drug trafficking and smuggling. In these cases, the information sent by express delivery may be discovered by the public security system and may be investigated and tracked.

In addition, some courier companies will also provide courier information inquiry services, such as courier number and telephone number, which may involve personal privacy and safety. If this information is leaked or abused, it may cause losses and troubles to individuals.

Therefore, when sending express delivery, it is recommended to choose a regular express delivery company, keep relevant vouchers and protect your legitimate rights and interests. At the same time, we should also pay attention to protecting our personal information and privacy to avoid disclosure or abuse.
