How long an EIN takes depends entirely on how you apply. The IRS issues it immediately online, but that instant route requires the responsible party to have a US Social Security Number or ITIN, so most non-resident founders cannot use it. For them the realistic options are fax, which the IRS says takes about four business days, the international phone line, which issues the number during the call, or mail, which takes about four weeks.
The IRS online tool requires a US SSN or ITIN. A foreign founder who has neither applies by fax, phone, or mail instead.
The IRS faxes the EIN back in about four business days. Mail is the slow fallback at about four weeks, and the international phone line issues the number on the call.
No one jumps the IRS queue, but fax comes back in about four business days where mail takes about four weeks. CORPBOLT's rush service files by fax, targeting about five business days.
How long it takes to get an EIN has one honest answer: it depends on how you apply, and for a founder outside the US the fastest option is usually off the table. The instant online route that gets a US-based applicant a number in minutes needs a US tax ID that most non-residents do not have. This page lays out the real timing for each method, with the routes a non-resident actually uses front and center. It is about timing only; the step-by-step of applying without an SSN is in getting an EIN without an SSN, and what the number itself is in what an EIN is.
How long an EIN takes, by method
The IRS offers four ways to get an EIN, and each has its own timing. The table below is the IRS's own guidance. The catch, covered right after it, is that the fastest one is closed to most non-resident founders.
Method | How long the IRS takes |
|---|---|
Online | Immediately, on screen |
Fax | About 4 business days |
Phone (international applicants) | Issued during the call |
About 4 weeks |
These are the IRS's stated timings, and it hedges every one with "about," "approximately," or "generally." They are estimates, not guarantees, and which row applies to you depends on one thing: whether you can use the online tool at all.
Why the instant online route is closed to most non-residents
The online EIN Assistant is the reason a US-based founder can get a number in one sitting. Its requirement is the reason you probably cannot. The IRS online tool needs the responsible party, the real person who owns or controls the LLC, to already hold a US Social Security Number, ITIN, or existing EIN. A founder abroad who has none of these is not eligible for the online tool. Instead, Form SS-4 lets a foreign responsible party enter "Foreign" on line 7b, and the application goes through by fax, phone, or mail. So the instant timeline simply does not apply to most non-resident founders, and the honest planning number is days to weeks, not minutes. The full mechanics of applying this way are in how to get an EIN without an SSN.
If you do qualify for the online tool
A minority of non-resident founders do hold a US Social Security Number or ITIN. If that is you, the online EIN Assistant is open to you and issues the number on screen. It comes with a few constraints worth knowing before you start. You have to finish in a single session, because the tool cannot be saved and resumed, and it times out after about fifteen minutes of inactivity, which sends you back to the beginning. The IRS also limits you to one EIN per responsible party per day. The tool runs only within a daily window in US Eastern Time, currently opening in the early morning on weekdays with shorter weekend hours, so check the current window on the IRS application page. When the number is issued, save or print the confirmation right away, since it is shown once and not emailed.
The realistic timeline for a non-resident founder
With the online tool out, three routes remain, and they differ a lot in speed.
Fax is the practical fast lane. The IRS says that if you apply by fax and give a return fax number, it faxes the EIN back in about four business days.
The international phone line is the fastest. The IRS lets applicants whose principal place of business is outside the US call 267-941-1099, a line open 6 a.m. to 11 p.m. Eastern time, Monday through Friday, and it is not toll-free. The number is issued during the call.
Mail is the slow fallback. A mailed application takes about four weeks to come back.
What you need before you apply
Whichever route you use, a little preparation keeps the application from stalling. Three things matter most for a foreign-owned LLC:
Form the LLC first. The IRS expects the legal entity to exist before you apply, and applying before your Wyoming formation is complete can delay or bounce the EIN. Get the state filing done, then apply.
Know your responsible party. The application names a responsible party, the real person who owns or controls the LLC, along with their tax ID if they have one. A foreign owner with no SSN or ITIN enters "Foreign" in that field on Form SS-4 rather than leaving it blank.
Authorize anyone filing for you. If a formation service submits the application on your behalf, it acts as a third-party designee, which you authorize in the designee section of the SS-4. Without that authorization the IRS will not deal with the filer.
Getting the number is not the same as being able to use it
There is a second timeline worth knowing. Once the IRS issues your EIN, you can use it immediately for most business needs, such as giving it to a bank or a payment processor. But the IRS says some of its own systems take up to about two weeks to recognize a brand-new EIN. Until then, you may not be able to use it to pass the IRS's Taxpayer ID Number matching, e-file a return, or make electronic tax deposits. For a founder whose next step is opening an account, the number is usable right away. If your next step is an electronic federal tax action, build in that short lag.
Why your wait can run longer than the IRS estimate
The four-business-days and four-weeks figures are the IRS's normal-conditions estimates, and it says so plainly: "High inventory levels may result in processing delays." In busy periods a faxed or mailed application can take longer than the headline number. This part no service controls. The queue is the IRS's, so even a faxed application can run past its estimate when volumes are high. A service can file by the fastest route and submit a clean application that avoids error delays, but no one can move you up the IRS queue or promise an exact date.
What if your EIN is taking too long?
If a reasonable time has passed and your EIN has not arrived, the fix is not to apply again. A second application can create a duplicate EIN that is a nuisance to untangle later. Instead, you confirm the number the IRS has already assigned. If the company was issued an EIN and you simply have not received the notice, a 147C verification letter retrieves it, and that process, including who to contact, is covered on its own page.
Rush and standard: how CORPBOLT files it
Because the gap between fax and mail is measured in weeks, CORPBOLT offers two handling speeds for your EIN, and the only difference is the route we file. Rush service submits your SS-4 application by fax, the fastest channel the IRS opens to a non-resident applicant, and in normal conditions the number comes back in about five business days. Standard service files by mail and runs about four to six weeks. Both send the same correctly prepared application, so what you are choosing is the filing method and, with it, the wait. Neither overrides the IRS's own schedule, and in busy periods the IRS itself flags that even a faxed application can run longer. But for most founders, rush is the difference between roughly a week and more than a month.
After you get your EIN
The EIN is the start of your obligations, not the end of them. Having the number does not, by itself, create a tax bill, but it does put the company on the IRS's radar for the filings its structure requires. For a foreign-owned single-member LLC, the main one is an annual Form 5472 filed with a pro forma Form 1120, due each year even in a year with little or no activity. It is worth knowing that obligation exists the moment you have the EIN, so it does not surprise you at tax time. Separately, check whether beneficial-ownership (BOI) reporting applies. A Wyoming LLC is a US-created company and is currently exempt under the prevailing rules, but because those rules have shifted before, confirm your status in do LLCs need to file a BOI report.
Frequently asked questions
How long does it take to get an EIN?
It depends on the method. Online is immediate but requires a US SSN or ITIN; by fax the IRS returns it in about four business days; by the international phone line it is issued during the call; by mail it takes about four weeks.
Can a non-resident get an EIN instantly online?
Usually no. The online tool requires the responsible party to have a US SSN, ITIN, or existing EIN. A foreign founder who has none of these applies by fax, phone, or mail instead, so the instant timeline does not apply.
How long does the EIN fax method take?
The IRS says about four business days, as long as you include a return fax number. It is the fastest practical route for most foreign-owned LLCs.
Can I get an EIN by phone?
Yes, if your principal place of business is outside the US. The IRS issues the EIN during a call to 267-941-1099, which is not toll-free and is open 6 a.m. to 11 p.m. Eastern time, Monday through Friday.
How soon can I use my EIN after I get it?
Right away for most business needs, such as opening a bank account. Some IRS electronic systems can take up to about two weeks to recognize a new EIN, which affects e-filing and electronic tax deposits.
Why is my EIN taking longer than four weeks?
The IRS notes that high inventory levels can cause processing delays, so busy periods run longer than the estimate. If it is well past the normal window, confirm the number with a 147C rather than reapplying.
Can CORPBOLT get my EIN faster?
Yes, by filing the faster way. No one can jump the IRS queue, but the IRS offers fax and mail routes with very different speeds: a faxed application comes back in about four business days, mail in about four weeks. CORPBOLT's rush service files by fax and targets about five business days end to end, while standard service files by mail at about four to six weeks. Peak-season IRS delays still apply to both, but the filing method is a real difference.
What do I need before I apply for an EIN?
Form the LLC first, since applying before your state formation is complete can delay the EIN. Have your responsible party and their tax ID ready, or enter "Foreign" if the owner has no SSN or ITIN, and authorize any service filing for you as a third-party designee on Form SS-4.
Can I pause the online EIN application and finish it later?
No. The IRS online tool must be completed in one session, cannot be saved, and times out after about fifteen minutes of inactivity. It also allows one EIN per responsible party per day, and it is only open to applicants who have a US SSN or ITIN.
Do I need to do anything after I get my EIN?
Yes. For a foreign-owned single-member LLC the EIN brings an annual Form 5472 filing with a pro forma Form 1120, due even in a quiet year. Also check your beneficial-ownership (BOI) status, which is currently exempt for a Wyoming LLC but worth confirming.
How this article was prepared
This timing guide was written by Edgar Loui Francisco of CORPBOLT for non-US founders applying for an EIN. The by-method timings (online immediate, fax about four business days, mail about four weeks), the international phone line and its hours, the online tool's US-tax-ID requirement and its one-session, fifteen-minute-timeout and one-per-responsible-party-per-day limits, the responsible-party and third-party-designee requirements, the "high inventory levels may result in processing delays" caveat, and the up-to-two-week gap before a new EIN clears all IRS systems are taken from the IRS Employer Identification Number pages and the Instructions for Form SS-4, with the Taxpayer Advocate Service confirming the same figures, all linked below. Processing time is controlled by the IRS, and every timing figure here is the IRS's own hedged estimate; the difference between the fax and mail speeds is the IRS's own, and we do not promise an exact IRS date. This is general information, not legal or tax advice, and we update it when the IRS changes the process. Last reviewed July 2026.
