About this product

An ITIN (Individual Taxpayer Identification Number) is a 9-digit tax number issued by the US Internal Revenue Service (IRS) to people who need to file US taxes but aren't eligible for a Social Security Number (SSN). It looks like an SSN but always starts with 9 (e.g. 9XX-XX-XXXX), with the middle two digits usually in ranges such as 70–88, 90–92 and 94–99. See our blog post "What is an ITIN?".

What an ITIN is for:

  • Filing US tax returns, claiming treaty benefits and some refunds.
  • Some US banks, brokers and payment platforms accept an ITIN instead of an SSN as a tax ID (requirements vary).
  • Reporting US income such as platform earnings or investment income.
⚠️ Before you buy
  • An ITIN is only a tax number — not US identity, a visa or residency, and it doesn't authorise work in the US.
  • An ITIN not used on a tax return for 3 consecutive years expires under IRS rules and must be renewed.

Steps

  1. Submit your personal information.
  2. Wait for the IRS to process it.
  3. Choose to receive a scan of the ITIN or have the original forwarded.
