How to Check ITIN Status and Find Your Number

Quick Answer

To check your ITIN status, call the IRS at 1-800-829-1040 (inside the US) or 1-267-941-1000 (outside the US) after waiting 7 weeks, or 9-11 weeks in peak season. The IRS has no online tracker. Your ITIN itself is printed on the CP565 notice the IRS mailed you. If you lost it, find the number on a past tax return or call the IRS to request a replacement notice.

How do I check my ITIN status?

You check your ITIN application status by phone. The IRS does not publish an online ITIN status tracker, so calling is the only official method. Follow these steps.

  1. Wait the minimum time. Allow at least 7 weeks after mailing Form W-7, or 9-11 weeks if you applied between January and April.
  2. Call the IRS. Dial 1-800-829-1040 inside the US or 1-267-941-1000 from outside the US. Lines are open 7 a.m. to 7 p.m. local time, Monday to Friday.
  3. Have your documents ready. Keep a copy of your W-7 and the identity documents you submitted so the agent can verify your application.
  4. Ask for the outcome. The agent will tell you if the ITIN is approved, still processing, rejected, or missing information.

How do I find my ITIN number?

Your ITIN is a 9-digit number that always begins with 9. You can find it in these places, in order of ease:

  • CP565 notice. This is the assignment letter the IRS mailed when it issued your ITIN. The number is printed near the top.
  • Past federal tax returns. Any return you filed with the ITIN shows it in the taxpayer identification field.
  • Tax documents. Forms like a 1099 or W-2 that were issued to you may display the ITIN.
  • Call the IRS. If none of the above work, call 1-800-829-1040. The IRS verifies your identity, then confirms the number or mails a replacement CP565.

The IRS will not give your ITIN to anyone who cannot pass identity verification, so keep your CP565 notice in a safe place.

How do I contact the IRS about my ITIN number?

The IRS handles ITIN questions by phone and mail only. There is no email address or online chat for ITIN matters.

How long does it take to get an ITIN approved?

The IRS approves an ITIN in 6-11 weeks from the day it receives a complete Form W-7. During peak tax season (January to April), plan for 11 weeks or more. A rejected application adds 4-8 weeks per correction cycle, which is why accuracy matters more than speed.

  • Off-peak (May-December): 6-8 weeks typical
  • Peak season (January-April): 9-11+ weeks
  • After approval: CP565 notice arrives by mail

Check ITIN Status: Frequently Asked Questions

How do I check my ITIN status?
Call the IRS to check your ITIN application status: 1-800-829-1040 inside the United States (toll-free) or 1-267-941-1000 outside the US (not toll-free). Wait at least 7 weeks after you mailed Form W-7 before calling, or 9-11 weeks during the January-April peak season. Have a copy of your W-7 and identity documents ready. The IRS has no online ITIN status tracker, so phone is the only official way.
How do I find my ITIN number?
Your ITIN is printed on the CP565 notice, the letter the IRS mailed when it assigned your number. If you lost the CP565, look on any prior federal tax return you filed with the ITIN, or on tax documents like a 1099 or W-2 that show it. If you cannot find it anywhere, call the IRS at 1-800-829-1040 to request a copy of your CP565. The IRS will verify your identity before sharing the number.
How do I contact the IRS about my ITIN number?
Contact the IRS ITIN line by phone: 1-800-829-1040 from inside the United States or 1-267-941-1000 from outside the US. Phone hours are 7 a.m. to 7 p.m. local time, Monday to Friday. You can also write to the IRS ITIN Operation, P.O. Box 149342, Austin, TX 78714-9342, the same address where W-7 applications are processed. There is no email or online chat for ITIN questions.
How long does it take to get an ITIN approved?
The IRS approves an ITIN in 6-11 weeks from when it receives a complete Form W-7. During the January-to-April tax season the wait stretches to 11 weeks or more because of high volume. Applying through a Certifying Acceptance Agent does not speed up the IRS review itself, but it reduces rejections, which is what usually adds weeks. Once approved, the IRS mails your CP565 notice with the ITIN.
Can I check my ITIN status online?
No. The IRS does not offer an online tool to track ITIN application status, unlike the Where's My Refund tool for tax refunds. The only official way to check is by phone at 1-800-829-1040 (US) or 1-267-941-1000 (international). Be cautious of third-party websites that claim to check your ITIN status online, as the IRS shares that information only over the phone after verifying your identity.
What should I do if my ITIN application is taking too long?
If more than 11 weeks have passed since you mailed Form W-7 and you have not received your CP565 notice, call the IRS at 1-800-829-1040. Common causes of delay are missing documents, an unsigned W-7, an expired passport, or filing during peak season. The IRS will tell you whether the application is still processing, was rejected, or needs additional information you can then supply.
How do I know if my ITIN has expired?
An ITIN expires if you do not use it on a federal tax return for 3 consecutive years, or if it has middle digits that the IRS retired under its rolling expiration program. If your ITIN has expired, you must renew it before filing. Renewing uses the same Form W-7 with the renewal box checked and takes the same 6-11 weeks to process.
Is there a fee to check my ITIN status?
No. Checking your ITIN status is free. The IRS charges $0 to tell you whether your Form W-7 is approved, pending, or rejected when you call 1-800-829-1040 inside the US or 1-267-941-1000 from outside it. Be cautious of any third-party website that charges a fee to check ITIN status, because the IRS provides this information only by phone at no cost.
What is a CP565 notice?
The CP565 is the official IRS notice that assigns or confirms your ITIN. The IRS mails it 6-11 weeks after approving your Form W-7, and your 9-digit ITIN is printed near the top. Keep the CP565 in a safe place, because it is the simplest way to find your ITIN later without calling the IRS at 1-800-829-1040.
