Individual Taxpayer Identification Number (ITIN) – Form W-7


An Individual Taxpayer Identification Number (ITIN) is assigned by the Internal Revenue Service to individuals involved in a transaction which may be a taxable event in the United States, who are ineligible to receive a a U.S. Social Security Number. It is not valid for personal identification, does not entitle the individual to work in the U.S. or to receive U.S. Social Security benefits.

Important Information

U.S. Embassies and Consulates are able to certify copies of foreign passports in relation to ITIN applications, but only for non-resident aliens applying for ITINs for the purpose of claiming tax treaty benefits (i.e. those applicants who are ticking “a” and “h” on the W-7 form). If you are applying for an ITIN for any other purpose, you will need to submit original documents, or apply from within the United States using an IRS ITIN Acceptance Agent. For further clarification, refer to the information on the IRS’s website.
