Fillable Form W-7
The W-7 form is used to apply for an individual taxpayer identification number, also known as ITIN. This form is used by non-citizens who aren't eligible to receive a Social Security number.

What is Form W-7?
Official Application for Internal Revenue Service (IRS) Individual Taxpayer Identification Number (ITIN), Form W-7 is a tax form used to apply for an ITIN in the United States. In the U.S., only citizens and non-citizens who are authorized to work are eligible to have a Social Security Number (SSN). An SSN is used to identify an individual when filing taxes to the federal tax agency. Even non-citizens without work authorization also need to file U.S. tax returns if they have income from U.S. sources. Hence, individuals who are unqualified to obtain an SSN from the Social Security Administration (SSA) may apply for an ITIN using the legal form.
An ITIN is a nine-digit unique number combination issued by the IRS. Aside from Form W-7 used to get an ITIN, it is also used to renew an expiring or has already expired identification number. According to the latest update from the IRS, an ITIN that has not been included on a U.S. federal tax return at least once in the last five consecutive years will expire.
If you are applying for an ITIN, to validate your application, you need to submit documents that confirm your identity and foreign status together with a completed Form W-7. You may submit the following:
Take note that you can only submit original documents and certified copies from the issuing agency. Original documents will be returned at the mailing address you have provided on your Form W-7.
