Received SMS notification from Social Security 12333. What does this SMS notification mean? I don't understand.

There are three ways to query social security:

Social security center, if you don't know your social security account number, you can bring your ID card to the business hall of social insurance agencies in various districts to inquire;

Inquire online, log in to the city's labor security network or social insurance business website, click the "Personal Social Security Information Inquiry" window, enter my ID card and password (the password is your social security number or the date of birth of the ID card), and inquire about my insurance information;

Telephone consultation, call the labor and social security comprehensive service telephone "12333" for policy consultation and information inquiry.
