Do New California Residents Need an SSN or ITIN?
By JC Pacific Corp Published 2026-09-01 Last professionally reviewed: September 2026
An SSN, ITIN, driver's license, state ID, and immigration document serve different purposes. One does not automatically replace or provide the rights associated with another.
What is an SSN?
A Social Security number is issued under federal eligibility rules and is used for employment, benefits, tax, and identification purposes.
What is an ITIN?
An Individual Taxpayer Identification Number is issued by the IRS to certain people who need a federal tax number but are not eligible for an SSN.
An ITIN does not:
- Authorize employment
- Provide immigration status
- Replace a driver's license
- Guarantee banking or credit
- Create Social Security benefit eligibility
