If you're in the U.S., you can apply online, then go to a local Social Security office to provide your documentation. Once your application is approved, you'll receive a Social Security card with your number on it by mail within 14 days.
You can find your Social Security number by checking your card, asking your guardian if they know it, checking certain documentation, talking with a former employer or requesting a new Social Security card.
You should be able to rent an apartment without a Social Security number provided you have a student visa or Permanent Resident Card (a.k.a. Green Card).
An Individual Taxpayer Identification Number (ITIN) is a tax processing number the Internal Revenue Service (IRS) issues to individuals who do not have and are not eligible for a Social Security number (SSN).
If it doesn't let you leave the SSN / ITIN field blank, enter something starting with 9, like 999-99-9999. ITINs start with 9, so that just tells the tax software you don't have a Social Security Number.
An individual may have an IRS individual taxpayer identification number (ITIN). If the individual does not have, and is not eligible for, an SSN, he or she must apply for an ITIN by using Form W–7.
A case cannot be created in E-Verify without an SSN. If a newly hired employee has applied for, but has not yet received his or her SSN (e.g., the employee is a newly arrived immigrant), attach an explanation to the employee's Form I-9 and set it aside.
You don't need an SSN to get a driver's license, register for school, get private health insurance, or apply for school lunch programs or subsidized housing. Some organizations use SSNs to identify you in their records. Most, however, will identify you by some other means if you request it.
If you do not have a Social Security Number (SSN) enter your Individual Tax Identification Number (ITIN). If you do not have an SSN or ITIN leave the entry field blank.
