You can check your ITIN number by obtaining a notice from the IRS that contains it. The IRS issues your ITIN on a formal notice, specifically Form CP-565, Notice of ITIN Assignment. This is the primary document that confirms your ITIN. If you have misplaced this notice, or if you have never received it, you must take specific steps to retrieve your ITIN. It is not possible to look up your ITIN online or through a simple phone call to the IRS without proper verification, due to strict privacy and security protocols.
This guide will walk you through the process of verifying your ITIN, what to do if you've lost your documentation, and alternative methods for obtaining your number. Understanding how to check your ITIN number is essential for filing U.S. tax returns and other financial obligations in the United States.
Confirming Your ITIN Assignment
The IRS assigns an ITIN only when you file a federal tax return or are required to have a U.S. taxpayer identification number for other tax purposes. The assignment is communicated via Form CP-565, Notice of ITIN Assignment. This notice is mailed to the address you provided on your tax return or ITIN application. It contains your unique nine-digit ITIN, which is formatted like a Social Security Number (SSN) but begins with the digits 9, and has a range of 70-88, 89, 90-92, or 94-99 in the fourth and fifth positions. For example, 9XX-70-XXXX.
If you successfully filed your taxes using an ITIN and received your Form CP-565, this document serves as your official confirmation. Keep this notice in a safe place along with your other important tax documents. If you have received this notice, you have confirmed your ITIN.
What to Do If You Lost Your CP-565 Notice
If you have lost your Form CP-565 notice, you cannot simply request a duplicate of the notice itself. Instead, you must request a letter from the IRS that contains your ITIN. This process involves contacting the IRS directly and undergoing a rigorous identity verification procedure.
Requesting an ITIN Verification Letter
To obtain a letter with your ITIN, you generally need to:
Call the IRS: You can call the IRS toll-free at 800-829-1040. Be prepared for potentially long wait times. When you reach an IRS representative, you will need to provide specific information to verify your identity. This typically includes:
- Your full name
- Your current mailing address
- Your previous addresses (if you have moved recently)
- Your date of birth
- Information from a previously filed tax return (e.g., the tax year, the type of tax return filed, and amounts from specific lines on that return if you have a copy).
- Other personally identifiable information to confirm you are the ITIN holder.
Write to the IRS: If you cannot verify your identity by phone, you can send a written request to the IRS. This request should include your full name, current mailing address, date of birth, and any other information that might help the IRS locate your tax records. You should mail this request to the address where you filed your most recent tax return. The IRS will then mail a letter containing your ITIN to the address they have on file. This process can take significantly longer than a phone call.
In-Person Assistance: In some cases, you may be able to visit an IRS Taxpayer Assistance Center (TAC) for help. However, you will still need to prove your identity and provide sufficient information for them to retrieve your ITIN. You must schedule an appointment in advance, and not all TACs offer this service. You can find your local TAC by using the IRS website's locator tool.
Be aware that the IRS will only send this information to the address they have on file for you. If you have moved and not updated your address with the IRS, you may not receive the letter. It is critical to ensure the IRS has your current mailing address on file, especially if you are expecting important tax-related correspondence.
What If You Never Received Your ITIN?
If you applied for an ITIN using Form W-7, Application for IRS Individual Taxpayer Identification Number, and have not received it, there are several reasons why this might occur. Processing times can vary significantly, especially during peak tax seasons. The IRS typically processes ITIN applications within 7 to 11 weeks. However, this can be longer if there are issues with the application, such as missing documentation or an incomplete tax return.
Checking Application Status
If you have submitted a Form W-7 application and are waiting for your ITIN, you can check the status of your application. The IRS allows you to do this by calling their dedicated ITIN line at 800-908-9982. Similar to checking for a lost ITIN, you will need to verify your identity. This typically involves providing information such as your name, date of birth, and an address from your submitted application. You can also inquire about the status of your application if you applied through a Certified Acceptance Agent (CAA). CAAs can often provide updates on the application's progress, as they are authorized by the IRS to help individuals with the application process. itin.net provides assistance through this Certified Acceptance Agent channel, streamlining the process for applicants.
If the IRS has completed processing your application, they will mail you Form CP-565, Notice of ITIN Assignment. If you have not received this notice after the expected processing time has passed, and your application status check does not indicate it has been mailed, you should contact the IRS immediately to investigate.
ITIN Renewal and Validity
It is important to understand that ITINs do not expire unless they have not been used on a federal tax return for three consecutive tax years. If your ITIN has expired due to non-use, you will need to renew it by filing a federal tax return with your ITIN. The IRS will automatically process your renewal when you file. If your ITIN has been invalidated or you have lost your documentation, the process to check your ITIN number remains the same: request a verification letter from the IRS.
When an ITIN is renewed, the IRS does not issue a new notice like Form CP-565. Instead, the renewal is processed as part of your tax filing. If you need to confirm your ITIN for a renewal year, and you have lost your original CP-565 notice, you will still need to follow the steps outlined above to request a verification letter from the IRS. This letter is the only official confirmation the IRS provides for a lost or unremembered ITIN.
Why You Need Your ITIN
Your ITIN is crucial for several financial and tax-related activities in the U.S. beyond just filing your annual tax return. It is often required when:
Opening a U.S. bank account: Many U.S. banks require an ITIN for non-residents to open accounts, especially if you do not have an SSN. This is a common requirement for individuals looking to manage their finances in the U.S., whether for personal or business purposes. Some financial institutions, like Mercury, Relay, or Brex, may have specific requirements or may offer services tailored to non-residents with ITINs, facilitating access to a U.S. bank account.
Filing U.S. tax returns: As mentioned, this is the primary reason for obtaining an ITIN. Whether you are a non-resident alien earning U.S. source income, claiming tax treaty benefits, or have other U.S. tax obligations, your ITIN is essential.
Establishing a U.S. business entity: If you form a U.S. LLC, you will likely need an ITIN or an EIN (Employer Identification Number) for tax reporting purposes. For instance, if you are a foreign-owned single-member LLC, you are required to file Form 5472, Information Return of a 25% Foreign-Owned U.S. Corporation or a Foreign Corporation Engaged in a U.S. Trade or Business, along with a pro forma Form 1120. An EIN is obtained by filing Form SS-4 with the IRS and is the standard for business identification. If you are forming a U.S. LLC, you will need to consider obtaining an EIN, which can be done through services like those offered by itin.net for EIN applications.
Applying for certain financial products: Beyond bank accounts, an ITIN might be needed for credit cards, loans, or other financial instruments, though this is less common and depends heavily on the institution's policies.
Without a confirmed ITIN, you may face significant challenges in fulfilling these obligations and accessing financial services in the United States.
Common Pitfalls When Checking Your ITIN
Several common issues can arise when trying to confirm or retrieve your ITIN. Understanding these pitfalls can save you time and frustration:
Incorrect Personal Information: Providing inaccurate or incomplete personal details when contacting the IRS or filling out forms is a primary cause of delays or rejections. Ensure your name, address, and date of birth match exactly what the IRS has on file.
Outdated Address: If you have moved and have not updated your mailing address with the IRS, any correspondence, including your ITIN verification letter, will be sent to your old address and likely lost. It is crucial to keep your contact information current with the IRS.
Misunderstanding Processing Times: The IRS has specific processing windows for ITIN applications and requests for verification letters. Patience is required, as these times can extend during busy periods. Avoid re-submitting requests multiple times within a short period, as this can further complicate matters.
Identity Theft Concerns: The IRS is highly vigilant about protecting taxpayer information. They have stringent identity verification procedures. If you cannot provide sufficient information to prove your identity, they will not release your ITIN, even if you are the rightful holder.
Confusing ITIN with EIN: An ITIN is for individuals, while an EIN is for businesses. They are distinct and used for different purposes. Ensure you are requesting the correct identification number and understand its function. If you are establishing a U.S. business, obtaining an EIN via Form SS-4 is a critical step, and services are available to assist with this process.
Not Having a Tax Filing Requirement: An ITIN is generally issued to individuals who have a U.S. tax filing or reporting requirement and do not qualify for an SSN. If you do not have such a requirement, you may not be eligible for an ITIN, and therefore, cannot 'check' for one you have not been assigned.
Seeking Professional Assistance
Navigating the IRS and its procedures can be complex, especially for individuals unfamiliar with the U.S. tax system. If you are struggling to locate your ITIN, verify your application status, or understand your tax obligations, seeking professional help is often the most efficient route.
Certified Acceptance Agents (CAAs)
Certified Acceptance Agents (CAAs) are individuals or entities authorized by the IRS to assist taxpayers in applying for ITINs. They can help verify your original identification documents, reducing the need to mail them to the IRS. While they cannot directly 'check' your ITIN number on your behalf in the sense of looking it up in an IRS database without your involvement, they can guide you through the process of obtaining a replacement notice or verification letter. Using a CAA like itin.net can simplify the application process and ensure accuracy, reducing the chances of errors that could delay your ITIN assignment or verification.
Tax Professionals
Enlisting the help of a qualified tax professional, such as a CPA (Certified Public Accountant) or an Enrolled Agent (EA), can be invaluable. These professionals have extensive knowledge of U.S. tax laws and IRS procedures. They can assist you in understanding your tax obligations, correctly filing your tax returns, and liaising with the IRS on your behalf if necessary. They can also advise on related matters, such as forming a U.S. LLC or obtaining an EIN for your business ventures.

In summary, checking your ITIN number primarily involves confirming you have received Form CP-565 from the IRS. If you've lost this, you must contact the IRS directly to request a verification letter, or seek assistance from a Certified Acceptance Agent. Remember, the IRS does not offer an online lookup tool for ITINs due to security reasons. If you are planning to establish a U.S. business, you will likely need both an ITIN and an EIN, and potentially a U.S. bank account; itin.net offers resources and assistance for all these steps, accessible via links to /ein, /llc, and /bank-account.
