EIN Wait Time: The Tax ID Is the Real Bottleneck for Your US Business Account
You form the LLC in a few days, and the thing that stalls your US business account is not the bank: it is the EIN wait time. The IRS assigns that nine-digit number on its own clock, and until it arrives, the account application cannot move.
The EIN wait time, not bank approval, is what actually blocks a US business account for a non-resident founder. The IRS says you can use your EIN immediately to open a bank account, so the bank only becomes the constraint once the number is in your hands. And the EIN is instant only through the online tool, which requires a US principal place of business and a responsible party with an SSN or ITIN. Everyone else is on fax, mail, or the international phone line: about 4 business days, about 4 weeks, or a call.
For a non-resident, the wait is front-loaded on the IRS, not the bank. Pick the EIN lane you can actually use, and the bank account is the fast part.
The order is fixed: entity, EIN, then bank
The IRS is explicit about the sequence. Before you apply for an EIN, “Form your entity first: If you’re creating a legal entity (LLC, partnership, corporation), register it with your state before you apply for an EIN.” State formation is the part that clears first, and it is where our guide to structuring an online business starts. The EIN comes next, and it is the step with the published, non-negotiable wait times. Only after the EIN does the bank become relevant, because the IRS lists “Open a bank account” as the first thing you can use your EIN for.
Why non-residents get the slow EIN lanes
The online EIN tool is the fast lane, but it has two gates. The Taxpayer Advocate Service states the conditions plainly: to use the online application, “Your principal business, office, or legal residence is in the U.S. or a U.S. Territory; and the responsible party… must have a valid Social Security number, Individual Taxpayer Identification number (ITIN), or EIN.” A founder who runs the business from abroad fails the first condition. That is why the same page closes the point with a single sentence: “International applicants can get an EIN by phone, mail, or fax, but not online.”
There is a second gate inside the application: the responsible party. The IRS requires the person “in charge of the entity and its assets” to be named with a Social Security number, an ITIN, or an EIN, plus a signature. For a solo non-resident founder, that responsible party is you, and if you do not yet have an ITIN, the only lanes open to you are the ones you can use from abroad.
The EIN wait time depends on which lane you can use
The wait is set by the lane, not by how good your documents are. These are the wait times the IRS itself publishes (read 2026-09-13):
| Lane | Who can use it | Wait time |
|---|---|---|
| Online | US principal place of business, plus a responsible party with an SSN or ITIN | Issued immediately |
| Fax (Form SS-4) | Anyone | About 4 business days |
| Mail (Form SS-4) | Anyone | Approximately 4 weeks |
| Phone | International applicants only | Issued during the call |
Two of those numbers are worth reading literally. The IRS writes that faxing the SS-4 returns the EIN “in about 4 business days” and that a mailed application returns “in approximately 4 weeks”. It also warns that “High inventory levels may result in processing delays”, the caveat that has caught founders during filing-season backlogs.
For international applicants the routing differs from the domestic one. Fax the SS-4 to 304-707-9471 (or 855-215-1627 from within the US), and mail it to the EIN International Operation in Cincinnati. The domestic US fax number is 855-641-6935. The phone lane is 267-941-1099, Monday to Friday from 6 a.m. to 11 p.m. Eastern time, and it is not toll-free.
The two-week catch after the number lands
The EIN unlocks the bank account immediately: “You can use your EIN immediately for most business needs. For example, when you: Open a bank account.” But the IRS publishes a second, quieter wait on the same page: “Wait up to 2 weeks to: Pass an IRS Taxpayer ID Number (TIN) Matching Program, E-file a tax return, Make tax deposits and pay electronically.” A brand-new EIN can take up to two weeks to validate in the TIN Matching Program, the system payers use to verify a tax ID against IRS records. So even after the number arrives, a TIN match can add a short second lag, and that lag tends to get blamed on the bank when it is the IRS again.
How to shorten the EIN wait time as a non-resident
The wait is mostly a function of the lane you pick, and a few choices move you to a faster one:
- ✓
Form the entity first, and use the exact legal name. The IRS says to register with your state before applying, and its systems accept only letters, numbers, hyphens and ampersands in the business name: enter it exactly as it appears on your formation documents.
- ✓
Fill out Form SS-4 before you call. The phone lane issues the EIN during the call, but the assistor works from the SS-4, so a completed form means you answer instead of stalling.
- ✓
Use the phone lane if you are international. 267-941-1099 runs Monday to Friday from 6 a.m. to 11 p.m. Eastern time and is the only immediate route for a founder without a US principal place of business. Budget for the time zone and the one-EIN-per-responsible-party-per-day limit.
- ✓
If you fax, provide a return fax number. The IRS sends the EIN back by fax in about 4 business days only when you give it a number to reply to; without one you fall back to the mail timeline.
Two habits drag the process out for no reason. The first is requesting a new EIN when the entity does not need one: the IRS requires a new EIN only on an ownership or structure change, and you do not need one just to change your business name, address or responsible party. The second is starting the application before the state registration is done: the IRS tells founders to register with their state first, before applying for an EIN.
Once the number lands, the bank is genuinely the easy part, and the failures there have a different cause. The US LLC setup guide walks through formation and paying yourself, and if the account still comes back rejected, here is why Mercury rejects applications and what actually fixes it.
FAQ
How long does it take to get an EIN?+–
It depends on the lane. Online the EIN is issued immediately, but only if your principal place of business is in the US and the responsible party has an SSN or ITIN. By fax it is about 4 business days, by mail approximately 4 weeks, and by phone an international applicant can receive it during the call.
Can I get an EIN online if I live outside the US?+–
Not through the online tool. The Taxpayer Advocate Service says international applicants get an EIN by phone, mail, or fax, but not online, because the online application requires a US principal place of business, office, or legal residence.
Do I need an EIN before I can open a US business bank account?+–
Yes. The IRS lists opening a bank account as one of the first things you can use your EIN for, and you can use the number immediately for that purpose once it is issued.
What is the fastest way for a non-resident to get an EIN?+–
The international phone line, because it issues the EIN during the call, Monday to Friday from 6 a.m. to 11 p.m. Eastern time. Fill out Form SS-4 first so you can answer the assistor’s questions, and remember the IRS issues only one EIN per responsible party per day.
