Individual Taxpayer Identification Numbers

Taxonomy Code: DF-7000.3400

Tax processing numbers issued in the United States by the Internal Revenue Service to certain nonresident and resident aliens, their spouses, and dependents who are unable to get a Social Security Number (SSN). Applicants must complete and submit a Form W-7 with required documentation substantiating foreign/alien status and the individual's true identity. Applicants may either mail the documentation, along with the Form W-7, to the closest IRS Service Center, present it at an IRS walk-in office, or process the application through an Acceptance Agent authorized by the IRS. Applicants not currently in the U.S. can apply from abroad.
