Business Refunds: Cincinnati and Ogden
Many people search for the "Cincinnati Refund Inquiry Unit" or the "Ogden Refund Inquiry Unit". Those two are for business entities, not individuals. A business east of the Mississippi, or in Arkansas or Louisiana, faxes Cincinnati at 855-307-3124. A business west of the Mississippi, or in Wisconsin, faxes Ogden at 855-578-2550. If you are tracing a personal refund, use the unit for your state in the table above.

Filers Abroad, Territories and APO/FPO
If your return has a foreign country address, a US possession or territory address or an APO/FPO address, or you filed Form 2555 or Form 4563, or you are a dual-status alien, fax Austin at 855-203-7538. It is the same number Austin uses for Florida, Louisiana, Mississippi, Oklahoma and Texas. OverseasFax works from any country in a browser, so a refund check that went missing in Lisbon or Lahore can be traced the same day. For other account questions from abroad, see our page on the IRS international fax line.
Only Form 3911 to These Numbers
The IRS is direct about this on its own page: do not send anything other than a Form 3911 to these fax numbers. Letters, other forms and replies to notices each have their own destination. Our guide to how to fax the IRS lists the right number for each one, and a CP2000 reply has its own page on faxing a CP2000 response.
The rule: one signed Form 3911 per fax, to the unit for your state or group, and nothing else in the fax. Send a separate form for each refund you are tracing.
Fax Form 3911 to the IRS, $2.99
Every Refund Inquiry Unit number is a US number. Select United States and type the 10 digits with no leading 1 and no spaces: Austin is entered as 8552037538, Fresno as 8553323068. See faxing a US number if you want more on the format.
Fill in the form with your details exactly as they appear on the return, including the tax year and the type of refund. If the refund came from a joint return, sign where the form asks for both spouses' signatures. Scan the signed form clearly. A cover page is optional; if you use one, keep it to one page with your name, "Form 3911" and the page count.
Mailing Form 3911 Instead
You can mail Form 3911 instead of faxing it. The mailing addresses are on the IRS About Form 3911 page; we list only the fax numbers here so nothing goes out of date in two places. Fax usually reaches the unit within a few minutes and gives you a confirmation email with the time it went through, which mail does not.

Cost, Confirmation and What Happens Next
A US number is in our first price tier: $2.99 for up to 3 pages, then $0.99 per extra page. Form 3911 usually fits in the base price. Tracing two refund years means two forms and two faxes, $5.98 in total. You see the price before you pay, and if a fax cannot be delivered the money goes back to your card automatically.
Your confirmation email records the destination number, the page count and the time in US Eastern Time. Keep it as your dated record of the day you started the trace. Before you send, check your refund status on IRS.gov so you know the refund was actually issued. We do not quote a response time, because it is set by the IRS. Its reply tells you what happens next, whether the check was cashed or not.
Why send it here
One price for the whole fax, shown before you pay, and nothing added at checkout.
Nothing is printed on your document. It arrives exactly as you uploaded it.
If it cannot be delivered, the money goes back to your card without you asking.
It works from anywhere. Send from any country, in any browser, with no account.

OverseasFax charges $2.99 for up to 3 pages and $0.99 for each extra page, from the US or any other country, with no account, no subscription and nothing added at checkout. Free fax services do exist, but they usually cap the number of pages and print their own advertising on the cover page, which you do not want on an IRS form.
Sending a fax
Can I fax Form 3911 to the IRS?
Yes. The IRS lists a fax number for every Refund Inquiry Unit on its About Form 3911 page. Use the unit for your state, or Austin at 855-203-7538 if you have a foreign address, a US territory or an APO/FPO address.
My refund check never arrived at my foreign address, what do I do?
Fax Form 3911 to the Austin Refund Inquiry Unit at 855-203-7538, the number for filers with a foreign address. First check your refund status on IRS.gov to make sure the refund was issued. Keep the confirmation email as your record of the date you started the trace.
Should I fax Form 3911 or mail it from abroad?
Fax it if you can. A fax usually arrives within a few minutes and you get a confirmation email with the time, while international mail can take weeks and gives you no record of arrival. Mailing addresses are on the IRS About Form 3911 page if you prefer mail.
What should I include with the faxed form?
The signed Form 3911 and nothing else. The IRS says not to send anything other than a Form 3911 to these fax numbers. If you add a cover page, keep it to one page with your name, the form number and the page count.
Do both spouses have to sign Form 3911 on a joint return?
If the refund was from a joint return, sign where the form asks for both spouses' signatures. A form missing a signature it asks for can be sent back, which delays the trace. Scan the signed page clearly so both signatures are readable.
Can I trace two missing refund years with one form?
Send one Form 3911 for each refund. Two missing years means two forms and two faxes to the same unit, $2.99 each, $5.98 in total.
Can I fax Form 3911 from my phone abroad?
Yes. Scan the signed form with your phone's scanner app, upload it at overseasfax.com in your browser, select United States, type the 10-digit number and pay $2.99. No app from us, no account and no fax machine.
Can I fax it on a weekend or at 3am my time?
Yes, you can send at any hour from any time zone. The fax usually arrives within minutes and the IRS handles it on its own working schedule. Your confirmation email records the exact time it went through, in US Eastern Time.
Can my US accountant or family member handle the trace for me?
A family member can send the fax for you once you have signed the form, but they should not sign it for you. For a tax professional to deal with the IRS on your behalf, authorize them with Form 2848 first; our Form 2848 guide covers where to fax it.
I moved countries after filing, which address controls?
If you now live abroad, or the return had a foreign address, fax Austin at 855-203-7538. Write your current address on the form so the reply reaches you, and update your address with the IRS separately.

I actually used a US state address on my return, does this page apply to me?
Yes. This page lists every Refund Inquiry Unit: find your state in the table and fax that unit, for example Fresno at 855-332-3068 for California or Brookhaven at 855-297-7736 for New York.
Can I fax anything else to 855-203-7538?

Do these IRS fax numbers change, and how do I verify before sending?
They can. The IRS keeps the list on its About Form 3911 page, which it last reviewed on October 14, 2026. Open that page the day you fax and match the number for your state or group.
What is the Austin Refund Inquiry Unit address or phone number?
This page lists only the fax numbers; the mailing addresses are on the IRS About Form 3911 page, and we do not publish a phone number for the unit. Faxing Form 3911 to 855-203-7538 reaches it within minutes.
Where do I mail Form 3911?
To the mailing address on the IRS About Form 3911 page for your state or group. Fax is faster and gives you a confirmation email with the time it went through.
Receiving a reply
Will the IRS fax me back about my refund trace?
Do not expect a reply by fax. If an IRS office does ask to fax you something, our sister service GetAFax.com gives you a US fax number for 24 hours for $5, and anything received arrives in your email.
Delivery, proof and safety
Does the IRS confirm receiving my faxed Form 3911?
Do not expect a receipt from the IRS when you send it. Your OverseasFax confirmation email, with the destination number, page count and time, is your dated record that the fax went through. Keep it for any call about your trace.
What if my fax to the Austin unit fails?
You are refunded the $2.99 automatically and can send again. Check that you typed 10 digits with no leading 1, 8552037538, and try again a little later if the line was busy.
How long does an international refund trace take?
We do not quote a time, because it is set by the IRS and we cannot verify it. The fax itself usually arrives within a few minutes, which saves the weeks international mail can take. Check your refund status on IRS.gov while you wait.
Is it safe to fax a form with my SSN from another country?
The fax goes point to point to the IRS number you enter and the file is deleted from our servers once it has gone. Nothing is printed on your document and there is no account. The main risk is a wrong number, so match it to the About Form 3911 page.
More questions
What is Form 3911?
Form 3911, Taxpayer Statement Regarding Refund, is the form you use to ask the IRS to trace a refund you did not receive. You fax or mail it to the Refund Inquiry Unit for your state or group.
Is there a filled-out sample of Form 3911 with the fax number?
We do not publish a sample; the form's own instructions are the safest guide. The fax number is not written on the form: it is where you send it, so pick it from the table on this page.
Why won't the IRS direct-deposit my refund to my foreign bank account?
We cannot confirm the IRS's current direct deposit rules here, so check the refund section of your return's instructions on IRS.gov. If your refund went out as a paper check to a foreign address and never arrived, the trace is Form 3911 faxed to Austin at 855-203-7538.
Can I check my refund status from abroad before filing a trace?
Yes. The refund status tool on IRS.gov works from any country. Check it first: a trace makes sense only once the refund shows as issued.
What happens if my refund check was never cashed?
The IRS reply to your trace tells you the next step. Make sure the address on your form is one where mail reliably reaches you, so the reply and anything that follows do not go missing too.
What happens if someone cashed my refund check?
The IRS reply to your trace tells you what happens next, and it may ask you for more information. Answer it by the method and deadline it gives, and keep a copy of everything you send.
What is the deadline for filing a refund trace?
No deadline is listed on the IRS About Form 3911 page. Trace as soon as the refund shows as issued and has not arrived, while the details are fresh.
What if I find the original check after the trace?
Do not cash it until you have checked with the IRS. If the trace already led to a replacement, the original may be canceled. Call the IRS, say the check turned up, and follow its instructions.
How do I stop next year's refund from going missing too?
Use direct deposit to a US bank account if you can, or a mailing address where mail reliably reaches you. Check the refund options in your return's instructions on IRS.gov. The trace fixes this refund; a better delivery method protects the next one.
