What is Taxpayer Identification Number (TIN)?
A taxpayer identification number (TIN) is a unique identification number used by the government to track individuals and businesses for tax purposes.
In the United States, the most common types of TINs are:
- Social Security Number (SSN): Used for individuals
- Employer Identification Number (EIN): Used for businesses, nonprofit organizations, and other entities
- Individual Taxpayer Identification Number (ITIN): Used for individuals who are not eligible for an SSN but need to file taxes, such as nonresident aliens or dependents of foreign nationals.
TINs are important for tax reporting, and individuals and businesses must provide their TIN when filing tax returns or conducting other financial transactions.

Is My Taxpayer Identification Number My Social Security Number?
For individuals in the United States, their TIN is often their Social Security number (SSN). When you apply for an SSN, you are automatically assigned a unique nine-digit number by the Social Security Administration (SSA). The Internal Revenue Service (IRS) uses this number as your TIN for tax purposes. It is typically printed on your tax forms and other financial documents.
However, there are some cases where an individual may have a different taxpayer identification number, such as if they are not eligible for an SSN or have applied for an Individual Taxpayer Identification Number (ITIN) from the IRS.
