To Get A Job You Need That Security Number, Can I Get Mine Online?

No. If you have lost it, you can replace your Social Security card for free if it is lost or stolen. However, you may not need to get a replacement card. Knowing your Social Security number is what is important.
To replace a lost Social Security card:
Complete an Application For A Social Security Card (Form SS-5); and
Show us documents proving your identity.
Show us documents proving your U.S. citizenship if our records do not already contain that information.
Show us documents proving your current, lawful, work-authorized status if you are not a U.S. citizen.
In most cases, you can mail or take your application and original documents to your local Social Security office. If you live in the New York City metropolitan area, Las Vegas Nev. Orlando Fla., Sacramento County, Calif. or Phoenix Ariz., you may need to apply in person at your local Social Security Card Center. http://ssa-custhelp.ssa.gov/cgi-bin/ssa.…
If you haven’t got a social security card, and want to apply, you can find the information at the same site.
