Social Security Number (SSN)

A Social Security Number (SSN) is a unique nine-digit identifier issued by the U.S. government to individuals primarily for tracking earnings and administering social security benefits. It also serves as a key form of identification for employment, tax purposes, and accessing certain financial and government services. The SSN is private and should be protected to prevent identity theft. While it doesn't indicate a person's citizenship status, it is essential for establishing legal employment and financial history in the U.S.
