How does the Social Security Bureau check personal files?

When I just graduated from graduate school, my personal file was sent directly to the city talent center where my account was located through confidential channels because the unit could not receive my personal file. This time, due to the need of job title application, I submitted my file to the city talent center where my account is located through the transfer letter issued by the talent market management office of my work unit, and the other party sent my file to the talent market management office of my work unit through confidential channels.

So I didn't hear that the file was in the Social Security Bureau, and I didn't look for a window to check the file from the website of the Social Security Bureau.
