From the perspective of law and privacy protection, directly using the personal information displayed on the package to actively contact neighbors may involve the protection of other people's privacy, so it needs to be handled with caution. The following suggestions are for your reference: 1. Privacy protection principle: The personal information attached to the package is usually only used for delivery purposes. Using this information for other purposes (such as directly contacting the recipient of the package) may not be consistent with the provisions of the "Personal Information Protection Law" and other relevant laws and regulations, and may even constitute a privacy violation. 2. Legitimate purpose and reasonable scope: If you just need to contact the recipient to return the wrongly delivered express, the purpose is legitimate and obvious, but the use of other people's information should still be kept to a minimum and the privacy of both parties should be protected. If the problem can be solved through other means (such as contacting the courier company or property), it is recommended to give priority to this method. 3. Recommended handling methods: ① Contact the courier company: You can report the situation to the courier company, and they will contact the real recipient based on the shipping information or other verification methods. This can not only ensure the return of the items, but also avoid the risk of you using other people's information privately. ② Leave a message or notify the property management: If you are familiar with your neighbors, or your community has relevant management departments, you can consider explaining the situation to your neighbors and informing them of the problem of the wrong delivery without disclosing detailed personal information. 4. Respect the privacy of others: During the handling process, try not to disclose or spread sensitive information on the package. At all times, respect and protect the legitimate privacy of others should be the premise. In short, although you have good intentions to solve the problem of wrong delivery, it is recommended to use official channels (such as express companies) to contact the real recipient during the operation to ensure that your own behavior complies with legal provisions while also protecting the personal information of others.
