ITIN Mailing Address: What to Do if USPS Shows Delivery Issues

The process of submitting an Individual Taxpayer Identification Number (ITIN) application can be challenging, particularly when dealing with postal delivery issues. These problems can delay the processing of tax identification documents, potentially affecting compliance with U.S. tax obligations.

Locating the Official Address for Submission

Submitting an ITIN application requires accuracy, especially in identifying the correct mailing address. The Internal Revenue Service (IRS) has designated specific addresses for ITIN applications. Form W-7 and accompanying documentation should be sent to the IRS Austin Service Center. Incorrectly addressing your application can lead to misrouting or returns.

For USPS submissions, the address is:
Internal Revenue Service, ITIN Operation, P.O. Box 149342, Austin, TX 78714-9342.

For private delivery services like FedEx or UPS, use:
Internal Revenue Service, ITIN Operation, Mail Stop 6090-AUSC, 3651 S. Interregional Hwy 35, Austin, TX 78741-0000.

Required Supporting Documents

Accurate supporting documents are critical for an ITIN application. These establish both identity and foreign status. A passport is the preferred document, as it satisfies both requirements. If unavailable, a combination of documents such as a national ID card, birth certificate, or foreign voter registration card, along with proof of foreign status (e.g., a visa), is acceptable.

Documents must be original or certified by the issuing agency; notarized copies are not accepted. Obtaining certified copies can take time, so planning ahead is essential to avoid delays. All documents must be current at the time of submission.

Additional documentation may be required for dependents. For example, a dependent child may need school or medical records, which must include the child’s name, date of birth, and address.

Confirming Delivery

Ensuring your ITIN application reaches the IRS is essential. The United States Postal Service (USPS) offers Certified Mail, providing a receipt and tracking number to verify delivery status online. Upon delivery, USPS confirms receipt.

Private courier services like FedEx or UPS provide advanced tracking and delivery confirmation, which are particularly useful for sensitive documents or expedited submissions. Retaining tracking numbers, receipts, and mailing dates is advisable for documentation and in case of delays or lost applications.

Address Discrepancies and Corrections

Errors such as misspelled names or incorrect birthdates can hinder the ITIN process. The IRS provides guidance for resolving these issues, typically requiring a corrected Form W-7 and supporting evidence.

Discrepancies can affect tax compliance, potentially delaying returns or resulting in penalties. Applicants should double-check all information before submission and act promptly to correct any errors. Keeping detailed records minimizes the risk of complications.

Alternative Submission Methods

While mailing is the most common submission method, alternatives exist for added convenience or security. These options can reduce risks associated with postal delays or lost documents.

Applicants may apply in person through an IRS-authorized Certifying Acceptance Agent (CAA) or at an IRS Taxpayer Assistance Center (TAC). CAAs can verify original documents, eliminating the need to mail sensitive papers. TACs allow direct submission to the IRS, but appointments are usually required.

For those living abroad, U.S. Embassies or Consulates can certify documents and forward applications to the IRS. This option is useful for navigating international mailing systems. Regardless of the submission method, applicants should retain copies of all forms and documents. Careful preparation and adherence to IRS requirements are key to a smooth application process.
