You generally cannot find your full Social Security number online through a public website
Check your Social Security card, tax returns, W-2s, pay stubs, or other official records
Log in to your my Social Security account at ssa.gov if you need SSA-related records
Contact the Social Security Administration directly if you need a replacement card or help verifying your number
If you lost your card, request a replacement through your my Social Security account or by visiting a local SSA office
Do not use websites that claim they can reveal your SSN online
If you suspect identity theft, place a fraud alert or credit freeze and contact the SSA and the FTC
