A Taxpayer Identification Number (TIN) is an identifying number used for tax purposes in the United States and in other countries under the Common Reporting Standard.

A TIN may be assigned by the Social Security Administration (SSA) or by the Internal Revenue Service (IRS).

Types

Any government-provided number that can be used in the US as a unique identifier when interacting with the IRS is a TIN, though none of them are referred to exclusively as a Taxpayer Identification Number. A TIN may be:

a Social Security number (SSN)
an Individual Taxpayer Identification Number (ITIN)
an Employer Identification Number (EIN), also known as a FEIN (Federal Employer Identification Number)
an Adoption Taxpayer Identification Number (ATIN), used as a temporary number for a child for whom the adopting parents cannot obtain an SSN^[1]
a Preparer Tax Identification Number (PTIN), used by paid preparers of US tax returns^[2]

SSNs

SSNs are used by people who have or had the right to work in the United States.

ITINs

ITINs are used by aliens who may or may not have the right to work in the US, such as aliens on temporary visas and non-resident aliens with US income.

EINs

EINs are used by employers, sole proprietors, corporations, LLCs, partnerships, non-profit associations, trusts, estates of decedents, government agencies, certain individuals, and other business entities.

Relevant Internal Revenue Code sections
