The property requires to fill in the ID number, work unit and address. Is it legal?

Whether the property requires to fill in the ID number, work unit and address is legal or not needs to be judged according to the specific situation.

Generally speaking, property companies need to collect personal information of owners or users, including ID number, work unit, address, etc., for property management, charging and maintenance. However, when collecting and using personal information, property companies must abide by the People's Republic of China (PRC) Personal Information Protection Law and other relevant laws and regulations, and cannot collect, disclose or abuse personal information at will.

Specifically, property companies should follow the following principles when collecting personal information:

1. Principle of legality: Property companies must abide by the provisions of national laws and regulations and collect personal information under the premise of legality.

2. Principle of necessity: Property companies can only collect necessary information related to property management, and cannot excessively collect personal information.

3. Principle of informed consent: Before collecting personal information, the property management company shall inform the owners or users of the purpose, scope and methods of collecting relevant information and obtain their informed consent.

4. Principle of confidentiality: The property management company shall take necessary measures to protect the personal information of the owner or user and prevent the personal information from being leaked, lost or damaged.

Therefore, if the property management company collects the personal information of the owner or user according to the above principles and takes necessary measures to protect the personal information, it is legal. However, it is illegal for property companies to collect, disclose or abuse personal information excessively, which violates relevant laws and regulations.

In short, whether the property company fills in the ID number, work unit and address is legal or not needs to be judged according to the specific situation. If you have questions or concerns about the behavior of the property management company, I suggest you consult relevant legal professionals or lawyers for judgment and consultation.
