Social Security Number Information
All U.S. employers require employees to have a Social Security Number (SSN). This unique nine digit identification number is issued by the U.S. government and is necessary for getting paid, paying taxes, getting a driver's license, obtaining credit cards and much more.
Once you obtain your SSN, you must guard it carefully. The Social Security Number is a permanent ID number. Only share your SSN with individuals or organizations whom you believe are trustworthy and have a valid reason for needing your social security number.
You can find more information about SSNs on the Social Security Administration (SSA) website.
