What does the social security personal code mean?

Personal social security code, also known as personal social security number and personal computer number.

Buying on behalf of personal social security is equivalent to buying in a city and giving it an identity tag. If you change cities, you will have another personal social security code. Because different cities and systems are different, a new social security number can be generated accordingly.

Where can I check the social security code? You can go to the insurance company to check the list, or you can bring your ID card to the Social Security Bureau.
