What an SSN is, who needs one, and where to apply near Irvine.
Updated: Jun 26, 2026
A Social Security Number (SSN) is a nine-digit number used to report your wages and to identify you for taxes, banking, and many services. It is one of the most important numbers you will have in the US.
Who needs one
- Anyone authorized to work in the US should get an SSN.
- You generally need it to be paid legally, to open some bank accounts, and to build credit.
- If you are not eligible for an SSN but must file taxes, you may instead need an ITIN (Individual Taxpayer Identification Number).
