Additional ITIN information

How can I obtain an ITIN from abroad?

Alien taxpayers who need an Individual Taxpayer Identification Number (ITIN) may be able to secure one from outside the United States. Details can be found on the "Obtaining an ITIN from Abroad" page.

Are ITINs valid for identification?

No. ITINs are not valid identification outside the federal tax system. ITIN applicants can apply in person or by mail; however, the IRS does not further validate the authenticity of identity documents. ITINs do not prove identity outside the Federal tax system, and should not be offered or accepted as identification for non-tax purposes.

Are ITINs valid for work purposes?

No. ITINs are for federal income tax purposes only. Getting an ITIN does not change your immigration status or your right to work in the United States.

Can ITINs be used as proof of identification to obtain a state driver’s license?

No. ITINs are not valid for identification outside the Federal tax system. For more information access the DMV communication PDF provided to the state departments of motor vehicles.

What do I do when I am assigned a Social Security number (SSN)?

Once you receive a SSN, you must use that number for tax purposes and discontinue using your ITIN. It is improper to use both the ITIN and the SSN assigned to the same person to file tax returns. It is your responsibility to notify the IRS so we can combine all of your tax records under one identification number. If you do not notify the IRS when you are assigned a SSN, you may not receive credit for all wages paid and taxes withheld which could reduce the amount of any refund due. You can visit a local IRS office or write a letter explaining that you have now been assigned a SSN and want your tax records combined. Include your complete name, mailing address, and ITIN along with a copy of your social security card and a copy of the CP 565, Notice of ITIN Assignment, if available. The IRS will void the ITIN and associate all prior tax information filed under the ITIN with the SSN. Send your letter to:

What ITIN information is available for tax professionals?

Information on filing tax returns using an ITIN is available for tax professionals. Although an ITIN/SSN mismatch is created when electronically filing tax returns reporting wages for ITIN holders, programming changes allow acceptance of these returns.

What is an ITIN acceptance agent?

An ITIN Acceptance Agent is an individual, business or organization (college, financial institution, tax practitioner, non-profit etc.) authorized by IRS to assist individuals in obtaining ITINs. Certifying Acceptance Agents (CAA) review applicants' documents and submit a completed Form W-7, along with a certificate of accuracy, copies of required documents, and tax return or exception documents to the IRS for processing. CAAs can authenticate all documents for primary and secondary applicants except foreign military identification cards. CAAs can only authenticate passports and birth certificates for dependents. For all other dependent documents, the CAA must mail the original document or certified copy from the issuing agency to IRS. Some Acceptance Agents may charge a fee.
