Waiting for your EIN? The IRS timeline is longer than the old “4-day” advice.
For non-US founders filing Form SS-4, the IRS’s current processing-status page says fax applications are being processed about 12 business days after receipt. Here’s when to wait, when to check, and how to avoid sending your form to the wrong queue.

12 business days
The IRS currently lists faxed Form SS-4 applications as processed about 12 business days after receipt. Its general EIN instructions still say fax responses are “generally” available in about 4 business days, so the live processing-status page is the better snapshot when inventory is high.

01 · Timeline
What a normal fax wait can look like now.
Your fax date and the IRS “receipt” date are not necessarily identical. Treat this as a practical checkpoint map, not a guaranteed delivery schedule.

Fax sent
Keep the transmission confirmation and a complete copy of exactly what you submitted.

Old benchmark
The standard SS-4 instructions still describe about four business days as the general fax target.

Current IRS status
As of October 2026, the IRS processing-status page reports faxed SS-4s at roughly 12 business days.

Still nothing?
Confirm status before repeatedly refaxing. Missing or inconsistent information can also delay processing.
Why Reddit looks inconsistent: founders are comparing different filing routes, different principal-place-of-business situations, different IRS workload periods, and sometimes different definitions of “sent,” “processed,” and “received back.”

EIN wait checker
Enter the date you faxed your SS-4. We’ll count weekdays as a simple proxy for business days and compare it with the IRS’s current 12-business-day processing benchmark.
Not a tracking tool. The IRS benchmark is measured after receipt, not necessarily the instant your fax service says “sent.” Federal holidays and special handling can also affect timing.
Your status will appear here.
Use your actual submission date.
03 · Routing
“Non-US resident” alone does not choose the fax number.
The IRS routes SS-4 applications based on where the applicant’s legal residence, principal place of business, or principal office/agency is located. That distinction is why founder forums contain conflicting fax-number advice.
Principal place of business outside the United States
The IRS’s current EIN page gives international applicants dedicated fax, mail and phone options.
Fax from outside U.S.304-707-9471
Fax from within U.S.855-215-1627
International phone267-941-1099

Do not choose a route just because your LLC was formed in Wyoming or Delaware.
Read the Form SS-4 instructions for your actual facts, especially the principal place of business and responsible-party sections. If the facts are unusual, professional tax advice is safer than copying a forum template.

04 · Before you chase the IRS
Check the things that commonly create uncertainty.
Recent founder discussions are less about the EIN fee—it is free—and more about whether the IRS received the fax, which number was correct, and whether the SS-4 itself was completed properly.
1
Responsible party
The responsible party generally needs to be the actual individual who owns or controls the entity, not a formation-service nominee.
2
No SSN or ITIN?
The December 2025 SS-4 instructions say a foreign responsible party who does not have and is ineligible for an SSN/ITIN can enter “foreign” or “N/A” on line 7b. An entry is still required.
3
Signature
Current IRS internal guidance clarifies that the signature element on relevant SS-4 submissions must be handwritten.
4
Return fax number
If applying by fax, include a fax number where the IRS can send the EIN response back to you.
5
One complete copy
Keep the exact SS-4 and transmission record. It makes a later status call far easier than rebuilding the application from memory.
6
Avoid duplicate applications
If the current window has not passed, repeatedly sending new SS-4s can create more uncertainty. Check status first when possible.
05 · Community pulse
What non-US founders are actually asking in 2026.
Recent Reddit threads line up closely with the official processing update: users are reporting waits beyond four days and asking whether to wait, refax, or call.
Reddit · Jul 2026
“20+ business days and no case visible”
A non-US Wyoming LLC owner described multiple fax attempts and IRS calls after the application was not yet visible—showing why “4 days” should not be treated as a guarantee.
Reddit · Aug 2026
“11 days with no answer—is that normal?”
The community discussion reflected a broad real-world range and advised checking the form and return-fax details rather than immediately sending another application.
Reddit · Sep 2026
“Which fax number is actually correct?”
Multiple new threads show founders confusing company formation state with principal place of business—the exact routing issue the IRS instructions distinguish.
