Can't I check other people's social security?

You can't check other people's social security information at will.

Social security information belongs to personal privacy, and only I or someone authorized by me can query it. Unauthorized people, including employers, family members or friends, can't query other people's social security information. If you want to inquire about other people's social security information, you must get the explicit permission of that person and abide by the relevant privacy and data protection laws.
