About the US ITIN
The ITIN (Individual Taxpayer Identification Number) is a 9-digit tax processing number issued by the IRS for individuals required to have a US taxpayer identification number who are not eligible for an SSN.
It always begins with the number '9' and has specific 4th and 5th digit ranges (50–65, 70–88, 90–92, 94–99) defined by the IRS.
