If you are an immigrant living in the United States, you have likely come across the terms ITIN and SSN.It is important to understand the distinction between these two numbers because they play a key role in financial management, tax filing, and building credit in the country.

What is a Social Security Number (SSN)?

A Social Security Number is a nine-digit number that the Social Security Administration issues to U.S.
citizens, permanent residents, and some immigrants who are allowed to work in the U.S.It is the main identification number used for employment, tax purposes, and accessing most financial services.

To be eligible for an SSN, you must be a U.S.
citizen, a permanent resident (holder of a green card), or have an immigration status that allows you to work in the United States, such as an H1B, L1, or F1 visa with work authorization.

What is an ITIN?

An Individual Taxpayer Identification Number is a nine-digit number issued by the Internal Revenue Service (IRS) to people who need to file U.S.
taxes but are not eligible for an SSN.All ITINs start with the number 9 and follow the format 9XX-XX-XXXX.

The IRS issues ITINs solely for tax-related purposes.
It does not allow you to work in the U.S.or change your immigration status.
