What is a TIN?
A Taxpayer Identification Number (TIN) is required to file taxes, receive government services, or operate a business. The TIN helps the IRS identify taxpayers and ensure correct tax payments. Different types of TINs exist based on the applicant. Common TINs include Social Security Numbers (SSNs) for individuals, Employer Identification Numbers (EINs) for businesses, and Individual Taxpayer Identification Numbers (ITINs) for noncitizens.

SSN vs TIN
Social Security Number
SSNs have 9 digits in an XXX-XX-XXXX format.
Employer Identification Number and ITIN
- The IRS assigns EINs to businesses and ITINs to noncitizens, both also have 9 digits.
- SSNs follow a different numbering pattern than ITINs. An SSN may be 123-45-6789.
- An ITIN always starts with 9, like 912-34-5678.
An individual may use an SSN. If ineligible for an SSN, they should apply for an ITIN with Form W-7. The payee’s TIN is required on tax documents, and one can check if a TIN is legitimate by searching the IRS database.
