Submitting an ITIN application is only the first step in the process. After mailing Form W-7 and your supporting documents to the IRS, most applicants are left wondering how long the process will take and how they can confirm that everything is moving forward correctly. Because the IRS does not offer an online tracking system for ITIN applications, understanding the correct way to monitor your status is extremely important.
This guide explains how to track your ITIN application, expected timelines, IRS communication methods, and what actions to take if delays occur.
What Is an ITIN and Why Status Tracking Matters
An Individual Taxpayer Identification Number (ITIN) is issued by the IRS to individuals who are required to file U.S. taxes but are not eligible for a Social Security Number. ITINs are commonly used by nonresident aliens, resident aliens, foreign investors, dependents, and spouses of U.S. taxpayers.
Because ITIN applications require identity verification and document review, processing is handled manually by the IRS. This makes tracking your application status especially important. Knowing when and how to perform an itin application status check
can help you avoid unnecessary delays and missed IRS notices.How Long Does an ITIN Application Take?
Before checking your application status, it’s important to understand normal processing timeframes. The IRS generally follows these timelines:
7 weeks for applications submitted outside peak tax season
9 to 11 weeks for applications filed between January and April
Additional time for applications mailed from outside the United States
Applications sent during tax season or with incomplete documentation may take longer. Checking your status too early usually results in no update because the application may not yet be entered into the IRS system.
How to Check Your ITIN Application Status
Although the IRS does not provide an online ITIN tracker, there are several reliable ways to obtain updates.
1. Call the IRS Directly
Calling the IRS is the most common method for checking ITIN status.
Within the U.S.: 1-800-829-1040
Outside the U.S.: +1-267-941-1000
When calling, be ready to provide:
Full legal name used on Form W-7
Date of birth
Mailing address listed on the application
Approximate submission date
Calling early in the day can help reduce wait times, especially during busy tax months.
2. Contact a Certified Acceptance Agent
If your ITIN application was submitted through a Certified Acceptance Agent (CAA), they may be able to follow up with the IRS on your behalf. CAAs are authorized to assist with ITIN applications and often have experience resolving delays or documentation requests.
This option is particularly helpful for applicants outside the U.S. or those who want professional assistance throughout the process.
3. Visit an IRS Taxpayer Assistance Center
Another option is scheduling an appointment at an IRS Taxpayer Assistance Center. Not all centers handle ITIN-related services, so confirm availability in advance. Visiting in person can be helpful if phone support is unavailable or if your case requires additional explanation.
IRS Notices You May Receive
Once your application is reviewed, the IRS sends official notices by mail. The IRS does not communicate ITIN decisions through email or online accounts, so checking your mailbox regularly is essential.
Common notices include:
CP565 Notice: Confirms that your ITIN has been approved and issued
CP566 Notice: Requests additional documents or clarification
CP567 Notice: Indicates the application was denied and explains the reason
Responding quickly to any IRS notice can significantly reduce further processing delays.
Best Practices While Waiting for Your ITIN
While your application is under review, following these best practices can help avoid problems:
Do not submit multiple applications unless instructed by the IRS
Keep copies of Form W-7 and all supporting documents
Track your mailing date to know when follow-ups are appropriate
Update your address if you move before receiving a response
Being organized and patient during this period can make the process smoother.
Common ITIN Application Issues and Solutions
Delays or complications are not uncommon. Here’s how to handle the most frequent problems:
No response after 14 weeks: Contact the IRS by phone to request a status update
IRS cannot locate your application: This may happen early in processing; wait a few weeks and call again
Original documents not returned: Originals are typically returned within 60 days; contact the IRS if this time has passed
Addressing these issues promptly helps prevent further delays.
