What happen to the Social Security Number when the company visa expires?

Does the social security also expires? When checked does it say anything? Like not valid? Or does it still have the person's information?
Btw it's a people visa and SSN.
Answers:   
yes, visitor didn't obtain ssc, but if they pass the expires the cops maid probably get them back to their own country if they find out.
Someone on visitor's visa is disallowed to get SSN and If ever your friend got one, it is illegal to use those especially for employment.
Students on F1 visa are allowed to enjoy one for purpose of opening bank accts, applying for credit etc..
Years ago [20+] I had a ssn # along with a indefinite visa, the social was stamped near a big red mark of "not valid for employment" this was only dutiful for opening a bank account etc which I did involve at the time.

since leaving the country and then coming back a few years ago and going through the immigration process I enjoy a new ssn with the same number basically in my new married name.
A being on a visitor visa does not get a Social Security Number.
