Individual Taxpayer Identification Number (ITIN) ITIN Apply Now

Line Instructions for ITIN

Enter N/A (not applicable) on all lines that do not apply to you. Do not leave any lines blank.

Line 1a.

Enter your legal name on line 1a as it appears on your documents. This entry should reflect your name as it will appear on a U.S. tax return.

Note.Your ITIN will be established using this name. If you do not use this name on the U.S. tax return, the processing of the U.S. tax return may be delayed.

Line 1b.

Enter your name as it appears on your birth certificate if it is different from your entry on line 1a.

Line 2.

Enter your complete mailing address on line 2. This is the address the IRS will use to return your original documents and send written notification of your ITIN.

Note. If the U.S. Postal Service will not deliver mail to your physical location, enter the U.S. Postal Service�s post office box number for your mailing address. Contact your local U.S. Post Office for more information. Do not use a post office box owned and operated by a private firm or company.

Line 3.

Enter your complete foreign (non U.S.) address in the country where you permanently or normally reside if it is different from the address on line 2. If you no longer have a permanent residence, due to your relocation to the United States, enter only the foreign country where you last resided on line 3. If you are claiming a benefit under an income tax treaty with the United States, line 3 must show the treaty country.

Note.Do not use a post office box or an �in care of� (c/o) address instead of a street address on line 2 if you are entering just a �country� name on line 3. If you do, your application will be rejected.

Line 4.

To be eligible for an ITIN, your birth country must be recognized as a foreign country by the U.S. Department of State.

Line 6a.

Enter the country or countries (in the case of dual citizenship) in which you are a citizen. Enter the complete country name; do not abbreviate.


If your country of residence for tax purposes has issued you a tax identification number, enter that number on line 6b. For example, if you are a resident of Canada, enter your Canadian Social Insurance Number.

Line 6c.

Enter only U.S. nonimmigrant visa information. Include the USCIS classification, number of the U.S. visa, and the expiration date in month/day/year format. For example, if you have an F-1/F-2 visa with the number 123456 that has an expiration date of December 31, 2012, enter �F-1/F-2,� �123456,� and �12/31/2012� in the entry space.

Note.If the visa has been issued under a �duration of stay� label by USCIS, enter �D/S� as the expiration date.

Line 6d.

Check the box indicating the type of document(s) you are submitting for identification. You must submit documents as explained in item (3) under How to Apply. Enter the name of the state or country or other issuer, the identification number (if any) appearing on the document(s), the expiration date, and the date on which you entered the United States. Dates must be entered in the month/day/year format. Also, you may subsequently be required to provide a certified translation of foreign language documents.

Note.Any visa information shown on a passport must be entered on line 6c.

Line 6e.

If you ever received a temporary taxpayer identification number (TIN) or an employer identification number (EIN), check the �Yes� box and complete line 6f. If you never had a temporary TIN or an EIN, or you do not know your temporary TIN, check the �No/Do not know� box. A temporary TIN is a nine-digit number issued by the IRS to persons who file a return or make a payment without providing a TIN. You would have been issued this number if you filed a U.S. tax return and did not have a social security number. This temporary TIN will appear on any correspondence the IRS sent you concerning that return. An EIN is a nine-digit number (for example, 12-3456789) assigned by the IRS to businesses, such as sole proprietorships.

Line 6f.

If you have both a temporary TIN and an EIN, attach a separate sheet listing both. If you were issued more than one temporary TIN, attach a separate sheet listing all the temporary TINs you received.

Line 6g.

If you checked reason f, you must enter the name of the educational institution and the city and state in which it is located. You must also enter your length of stay in the United States. If you are temporarily in the United States for business purposes, you must enter the name of the company with whom you are conducting your business and the city and state in which it is located. You must also enter your length of stay in the United States.


You must sign Form W-7. However, if the applicant is a minor under 14 years of age, a delegate (parent or court-appointed guardian) can sign for him or her. Type or print the delegate�s name in the space provided and check the appropriate box that indicates his or her relationship to the applicant. If the delegate is signing as a court-appointed guardian, attach a copy of the court-appointment papers showing the legal guardianship.
If the applicant is 14 years of age or over, the applicant can sign or appoint an authorized agent to sign. The authorized agent could be the applicant�s parent or another person designated by the applicant. The authorized agent must print his or her name in the space provided for the name of the delegate and attach Form 2848.
Note. All Powers of Attorney (POAs) submitted to the IRS must be in English. Any POAs received in a foreign language will be considered invalid unless accompanied by a certified English translation.
