Lock Your Social Security Number at e-verify | Prevent Identity and Employment Social Security Theft
Article Excerpt: "...Why Use Self Lock? Employment-related identity fraud could mean that someone else is working under your identity and using your SSN. If this happens, someone else’s wages could be reported in your name to the Internal Revenue Service, the Social Security Administration, and other authorities. By using Self Lock, you can block someone from committing this fraud if they start working for an E-Verify employer. Even if you are not currently working, you may want to protect your SSN and identity with Self Lock. How to Use Self Lock
To access Self Lock, you must be logged in to your myE-Verify account.
To lock your SSN, you must select and answer three challenge questions. Select questions you can easily answer, because you will need to answer them again to verify your identity if you receive an E-Verify Tentative Nonconfirmation (mismatch) due to Self Lock.
If you are about to start a new job with an E-Verify employer, you should log into your account and unlock your SSN."
