Social Security Number (SSN) & ITIN Guide
Step-by-step instructions for applying for an SSN at the SF Social Security Administration office (90 7th St) and ITIN setup.
Table of contents
A Social Security Number (SSN) is a 9-digit numerical identifier issued by the US Social Security Administration (SSA). It serves as your primary tax identification number for US payroll, credit reporting, background checks, and income verification.
What is an SSN and Why Do You Need It?
In San Francisco, while you can open a checking account or sign a lease without an SSN using passport verification, having an SSN is essential to:
- Be added to US corporate payroll and receive proper tax withholding.
- Establish a FICO credit score reported to Experian, Equifax, and TransUnion via credit building pathways.
- Avoid manual offline background verification delays when applying for apartments.
Eligibility by Visa Category
Not all visa holders can apply for an SSN immediately upon arrival. You must possess work authorization tied to your specific visa class.
| Visa Category | Required Original Documents | Work Authorization Proof | Expected Processing Window |
|---|---|---|---|
| H-1B / L-1 / O-1 / TN / E-3 | Passport, Visa, I-94 Arrival Record, Form I-797 Approval Notice | Employment verification letter + Form I-797 | 7 – 14 Business Days after appointment |
| F-1 OPT / STEM OPT | Passport, Visa, I-94, Form I-20 with OPT endorsement | Employment Authorization Document (EAD Card) | 7 – 14 Business Days |
| J-1 Scholar / Intern | Passport, Visa, I-94, Form DS-2019 | Sponsor employment authorization letter | 7 – 14 Business Days |
| H-4 / L-2 Spouse (No EAD) | Passport, Visa, I-94, Marriage Certificate | Apply for ITIN via Form W-7 during tax filing | 6 – 9 Weeks (IRS processing) |
The 10-Day Post-Arrival SAVE Database Rule
⚠️
Wait 10 Days After Entering the US
Do not visit the SSA office immediately after flying into the US. You must wait 10 business days after your physical entry for US Customs and Border Protection (CBP) to synchronize your arrival record with the Department of Homeland Security SAVE (Systematic Alien Verification for Entitlements) database. Applying before SAVE updates will trigger a manual verification review, delaying your SSN card by 4 to 8 weeks.

ITIN (Individual Taxpayer Identification Number) for Dependents
