Social Security Administration (SSA)
If you detect fraudulent use of your social security number, report it to the SSA. The SSA does not generally take action unless there is a high dollar amount, workplace impersonation or crimes committed in your name. They will only change your SSN if you fit their fraud victim criteria.
