Social Security Number Information

A social security number (SSN) is a life long nine digit number that the U.S. government issues to eligible individuals to keep track of their earnings and number or years worked. U.S. employers require their employees to have a social security number to receive payment and to withhold taxes.

Students and scholars who have secured on-campus employment, have PhD fellowships, or have been authorized for off-campus employment may be eligible to apply for a Social Security Number (SSN).

If you are not eligible for a social security number but you are seeking a Denial Letter from the Social Security Administration (SSA) to apply for a Massachusetts Learner's Permit/Driver's License/State ID, you must go to a SSA office with your immigration documents to request a Denial Letter.
