If you mailed only a name-change letter, the IRS gives no specific deadline or promise of a new confirmation letter; if you filed Form W-7, use 7 weeks—or 9 to 11 weeks during January 15–April 30 or from overseas—as the notice window.
“I recently got married and submitted a legal name change to the IRS. How long does it usually take for the change to be processed and to receive the ITIN confirmation letter with my new name?”
Summary
The IRS recognizes a letter explaining your marriage, with documentation such as a copy of your marriage certificate, as the correct way to update an existing ITIN name. The frustrating part is that it publishes no completion time or replacement-letter promise for that letter-only route.
Your answer depends on whether you sent only a name-change letter or also filed Form W-7.
This is the route. The IRS says to send a letter explaining the marriage and include documentation such as a copy of the marriage certificate, but it states no processing time and does not promise a replacement confirmation letter (IRS ITIN page, updated October 28, 2025).
This is the application or valid renewal route. Allow 7 weeks for an IRS status notice, or 9 to 11 weeks if submitted January 15 through April 30 or from overseas; a renewal under a changed legal name needs proof such as a marriage certificate or court order (IRS ITIN page; Form W-7 Instructions, rev. December 2024).
The IRS publishes a notice window only for the Form W-7 branch, not for the letter-only branch.

Next steps
These steps help you identify the correct timeline, follow up, and protect any original documents you mailed.
First
Match your packet to the correct branch
If the packet contained only a letter explaining the marriage plus supporting proof, use the standalone branch: there is no published completion time or promised replacement letter. If it contained Form W-7 for an application or valid renewal, use the Form W-7 notice window.
Requirements
For Form W-7: after 7 or 9–11 weeks
Contact the IRS when your branch calls for it
For a Form W-7 submission, call if no notice arrives within 7 weeks, or within 9 to 11 weeks when submitted January 15 through April 30 or from overseas. Call 800-829-1040 in the United States, 7 a.m. to 7 p.m. local time; from abroad call 267-941-1000, which is not toll-free. For a letter-only update, the IRS gives no wait threshold, so use the same individual-help line to request status when you need confirmation.
Requirements
At 60 days
Follow up on original documents
If original supporting documents have not been returned within 60 days, contact the IRS at 800-829-1040 in the United States or 267-941-1000 from abroad.
Requirements
Only if TAS criteria apply
Request Taxpayer Advocate Service help if the delay becomes serious
TAS may help when a delay is more than 30 days beyond the regular processing time or when the IRS missed a specific promised response date; separate financial-difficulty or immediate-adverse-action criteria can also qualify. Submit Form 911 by email to TAS.Form.911.Request.for.Assistance@irs.gov. Because the IRS publishes no regular time for a standalone name-change letter, rely on a documented hardship or missed promised date rather than inventing a 30-day starting point.
Requirements
Legal sources
The answer comes from the IRS ITIN page, the IRS Instructions for Form W-7, and the Taxpayer Advocate Service assistance criteria.
IRS ITIN page — Name changes
This establishes the current procedure for an existing ITIN holder's marriage-related name update.
Update your information — Name changes
If you changed your name after you received your ITIN, notify us so we can update your information. Send a letter that explains the change (marriage, divorce, etc.). Include documentation, such as a copy of your marriage certificate, divorce decree or court record.
IRS ITIN page — Application status
This establishes the notice window for an ITIN application and the longer window for tax season or overseas applications—not a standalone name-change deadline.
After you apply
Allow 7 weeks for us to notify you about your ITIN application status. It can take 9-11 weeks if it's tax season (January 15 to April 30) or if you applied from overseas. If you don't receive a notice from us within this timeframe, contact us.
IRS ITIN page — Individual help
These are the IRS phone numbers for individual callers in the United States and abroad.
Contact information
Individuals (U.S.) 800-829-1040 7 a.m. to 7 p.m. local time Individuals (abroad) 267-941-1000 (not toll-free)
Instructions for Form W-7 (Rev. December 2024)
This establishes the extra evidence required when a valid ITIN renewal is filed under a changed legal name.
Line instructions, page 8
Note. If you’re renewing your ITIN and your legal name has changed since the original assignment of your ITIN, you’ll need to submit documentation to support your legal name change, such as your marriage certificate or a court order, which may include a divorce decree. Attach supporting documentation to Form W-7.
IRS ITIN page — Original documents
This gives a separate follow-up point for original supporting documents that have not been returned.
After you apply
If you mailed original supporting documents and haven't received them within 60 days, contact us.
Instructions for Form W-7 (Rev. December 2024)
This establishes that someone with, or eligible for, an SSN should not use Form W-7.
General Instructions, page 2
Don’t complete Form W-7 if you have an SSN or if you’re eligible to get an SSN. You’re eligible for an SSN if you’re a U.S. citizen or if you’ve been admitted by the United States for permanent residence or U.S. employment.
TAS request-for-assistance criteria
This establishes one delay criterion for Taxpayer Advocate Service help and the alternative missed-promised-date criterion.
Case criteria
A delay must be more than 30-days after regular processing time to resolve a tax-related problem. If the IRS was supposed to respond to you or resolve your account by a specific date and they have not, you may qualify for TAS assistance.
These are the official rules as published on the cited dates; rules can change.
