Document Requirements Overview
The IRS requires specific documentation to verify your identity and foreign status for ITIN applications. All documents must be original or certified copies from authorized officials.
Two-Document Rule
You must provide either ONE primary document OR a combination of TWO secondary documents that together establish your identity and foreign status.
Document Categories
- Primary Documents: Stand-alone documents that prove identity and foreign status
- Secondary Documents: Must be used in combination to meet requirements
- Supporting Documents: Additional proof of tax purpose or relationship
- Certified Copies: Professionally authenticated copies of original documents
Primary Documents (Choose ONE)

Secondary Documents (Choose TWO)
If you cannot provide a primary document, you must submit a combination of two secondary documents.
