Types of Tax Identification Numbers (TIN)
- Social Security number (SSN): The primary TIN issued to U.S. citizens, permanent residents, and certain temporary residents by the Social Security Administration. SSNs, formatted as XXX-XX-XXXX, are essential for legal employment and accessing social security benefits and government services.
- Individual Taxpayer Identification Number (ITIN): This TIN is granted by the IRS to nonresident and resident aliens, their spouses, and dependents ineligible for SSNs, following a format similar to SSNs (XXX-XX-XXXX). Applicants must complete Form W-7 and provide proof of residency to secure an ITIN.
- Employer Identification Number (EIN): Utilized by the IRS to identify corporations, trusts, and estates liable for taxation purposes. EINs consist of nine digits in the format XX-XXXXXXX and are crucial for reporting income and capital gains to tax authorities.
- Adoption Tax Identification Number: Applicable in domestic adoptions when adoptive parents lack the child’s SSN for tax purposes. The child must be a U.S. citizen or permanent resident with a pending adoption.
- Preparer Tax Identification Number: Mandatory for tax preparers filing tax returns for clients in adherence to IRS regulations.
Parents must secure an SSN for their child before claiming them as dependents for tax purposes.
When Is a TIN Required?
A Taxpayer Identification Number (TIN) is essential for individuals, businesses, and organizations for tax-related activities and compliance monitoring by the IRS. The requirement for a TIN arises in various scenarios:
- Credit: Banks and lenders seek Social Security numbers on credit applications to verify identity and report credit activities to bureaus.
- Employment: Employers mandate SSNs to confirm work authorization in the United States.

The abbreviation TIN signifies “tax identification number” or “taxpayer identification number.”
