Quick answer
The IRS does not offer an online ITIN tracker.
To check status you either wait for an official notice in the mail (CP565, CP566, or CP567), call the IRS at 1-800-829-1040 (U.S.) or +1-267-941-1000 (international), or ask the Certified Acceptance Agent who submitted your application.
IRS ITIN processing timeline
Most ITIN applications take 7 to 11 weeks from the day the IRS receives your complete package. Peak tax season (January–April) and international mail add time.
IRS receives your W-7 package
The clock starts when the IRS ITIN Operation in Austin, TX physically opens your envelope — not the day you dropped it in the mail.
Document review
An examiner verifies your Form W-7, your identity document (passport or supporting docs), and your attached federal tax return or exception documentation.
Decision & notice mailed
The IRS mails either a CP565 (ITIN assigned), a CP566 (more info needed), or a CP567 (application rejected). International mail can add 2–4 weeks.
How to call the IRS about your ITIN
The IRS will only give a status update after your application has been on file for at least 7 weeks (or 9–11 weeks during peak season). Calling earlier isn't useful — the examiner hasn't touched it yet.

IRS notices to watch for in the mail
Every ITIN application ends with an official IRS letter. Which one you receive tells you exactly where you stand.
ITIN assigned
Your ITIN was issued. The number is printed on the notice — keep it for your tax records.
More information needed
The IRS needs additional or corrected documentation. Respond within 45 days with exactly what the notice asks for, or the application is closed.
Application rejected
Your ITIN application was denied. The notice lists the reason — the most common causes are unsigned W-7 forms, missing tax returns, or documents that don't meet IRS certification rules.
When to actually worry
Under 7 weeks: normal — do nothing yet.
7–11 weeks: if nothing has arrived, call the IRS at the number above.
Over 14 weeks and no letter: ask the IRS examiner to open a trace. It's usually a mail issue, not a rejection.
CP566 in your mailbox: respond fast. You have 45 days before the file is closed and you have to reapply from scratch.
