How to Track Your ITIN Application Status Step by Step
Posted: Mon Feb 02, 2026 11:21 am
Applying for an Individual Taxpayer Identification Number (ITIN) is an essential requirement for many individuals who must file U.S. taxes but are not eligible for a Social Security Number. After submitting Form W-7 and the necessary supporting documents, most applicants enter a waiting phase filled with uncertainty. Since the IRS does not provide an online tracking system for ITIN applications, knowing how to check your application status correctly becomes extremely important.
This guide explains how ITIN processing works, how long it usually takes, the correct ways to follow up with the IRS, and what actions to take if your application is delayed.
What Is an ITIN and Why Tracking Matters
An ITIN is a tax identification number issued by the Internal Revenue Service to individuals who are required to file U.S. tax returns but do not qualify for a Social Security Number. This includes nonresident aliens, resident aliens, foreign investors, dependents, and spouses of U.S. taxpayers.
Because ITIN applications involve identity verification and manual review, processing can take time. Tracking your application helps ensure you don’t miss important IRS notices or requests. Knowing when and how to perform an itin application status check
allows you to stay informed and take action if needed.
ITIN Application Processing Timeframes
Before contacting the IRS, it’s important to allow sufficient processing time. Typical ITIN processing timelines include:
Approximately 7 weeks during non-peak periods
9 to 11 weeks during tax season (January through April)
Additional delays for applications mailed from outside the U.S.
If you try to check your status too soon, the IRS may not yet have entered your application into their system.
How to Check Your ITIN Application Status
While there is no online portal for ITIN tracking, there are several reliable methods available.
1. Call the IRS for a Status Update
Calling the IRS is the most common way to check your ITIN application status.
U.S. callers: 1-800-829-1040
International callers: +1-267-941-1000
When calling, have the following information ready:
Full name as listed on Form W-7
Date of birth
Mailing address used on the application
Approximate date the application was submitted
Calling early in the day often results in shorter wait times, especially during peak tax months.
2. Follow Up Through a Certified Acceptance Agent
If you applied using a Certified Acceptance Agent (CAA), they may be able to contact the IRS on your behalf. CAAs are authorized by the IRS to assist with ITIN applications and can often help clarify delays or documentation issues.
This option is especially helpful for international applicants or those who prefer professional assistance.
3. Visit an IRS Taxpayer Assistance Center
You may also schedule an appointment at an IRS Taxpayer Assistance Center. Not all locations provide ITIN services, so it’s important to confirm availability beforehand. In-person assistance can be useful if phone access is limited or if your situation requires additional explanation.
IRS Notices You Should Expect
Once your application has been reviewed, the IRS sends a notice by mail. The IRS does not send ITIN decisions via email or online accounts, so checking your mailbox regularly is critical.
Common IRS notices include:
CP565 Notice: Confirms your ITIN has been approved and issued
CP566 Notice: Requests additional information or documentation
CP567 Notice: Indicates your application was rejected and explains the reason
Responding promptly to any notice helps avoid further delays.
What to Do While Waiting for Your ITIN
The waiting period can feel frustrating, but following these best practices can prevent problems:
Avoid submitting duplicate applications, as this may delay processing
Keep copies of Form W-7 and all supporting documents
Track your submission date so you know when to follow up
Update your address with the IRS if you move before receiving a response
Staying organized makes it easier to resolve issues if the IRS contacts you.
Common ITIN Application Issues and Solutions
Delays or complications sometimes occur. Here’s how to handle common situations:
No response after 14 weeks: Contact the IRS for a follow-up
IRS cannot locate your application: This may occur early in processing; wait a few more weeks and try again
Original documents not returned: Originals are typically returned within 60 days; contact the IRS if this timeframe has passed
Acting quickly can prevent minor issues from becoming major delays.
Final Thoughts
Tracking your ITIN application doesn’t need to be overwhelming. By understanding IRS processing timelines, using the correct follow-up methods, and monitoring mailed notices, you can stay informed throughout the process. Patience, preparation, and accurate record-keeping are key to a successful outcome.
