If you are a non-US resident trying to start a business in the United States, one of the first hurdles you will face is obtaining an Employer Identification Number — commonly known as an EIN — without a Social Security Number. The good news is that the IRS explicitly allows foreign nationals to apply for an EIN without SSN. In this 2026 guide, I will walk you through the exact process, share my own real experience as a Japanese-based business owner with cross-border operations, and help you avoid the costly mistakes I have seen firsthand.
The Bottom Line: You Can Get an EIN Without SSN in 2026
In One Sentence
Non-US residents can legally obtain an EIN without an SSN by filing IRS Form SS-4 and providing a foreign passport number or ITIN as an alternative identifier. The IRS does not require you to be a US citizen or permanent resident to receive an EIN — period.
This is not a loophole or a gray area. The Internal Revenue Service has published clear instructions stating that foreign persons who need an EIN for US business purposes are eligible applicants. Whether you are forming a Wyoming LLC, opening a US bank account, or launching an e-commerce store that serves American customers, the EIN without SSN pathway is fully legitimate.
Why This Is the Definitive Answer (3 Key Reasons)
- IRS Form SS-4 explicitly accommodates foreign applicants. Line 7b of the form allows you to enter a foreign country name instead of a US state. The instructions also note that applicants without an SSN or ITIN can leave those fields blank and still receive an EIN by fax or mail.
- Federal law does not restrict EIN issuance by nationality. The Internal Revenue Code treats the EIN as a taxpayer identification number for entities, not individuals. A single-member LLC owned by a non-resident alien or a multi-member LLC with all foreign members can obtain one without any US-based social security documentation.
- Thousands of foreign entrepreneurs do this every year. As someone who has incorporated a Japanese kabushiki kaisha (stock corporation) and also holds real estate assets in the Philippines and Hawaii, I can confirm from direct experience that the process works. I obtained my first EIN for a US entity in 2019 without having an SSN, and it took less than two weeks from submission to confirmation letter.
My Real Experience: Getting an EIN Without SSN as a Foreign Business Owner
How I Applied for My EIN from Tokyo in 2019
Let me take you back to early 2019. I was sitting in my office in Tokyo, staring at a blank IRS Form SS-4, feeling genuinely confused. As an AFP (Accredited Financial Planner certified by the Japan FP Association) and a licensed takkenshi (宅地建物取引士), I was no stranger to financial paperwork. But US tax forms operate on a completely different logic, and the instructions felt circular.
At the time, I was setting up a US-based LLC to manage income from my Hawaii property investment. I had purchased a condominium unit in Honolulu in 2018, and my accountant in Japan told me that having a US entity with its own EIN would simplify tax reporting under the US-Japan tax treaty. The problem was obvious: I did not have an SSN, and the online EIN application on the IRS website required one.
So I went the fax route. I completed Form SS-4 by hand, left the SSN/ITIN field blank, entered my Japanese passport number in the “other” identifier section, and faxed it to the IRS’s dedicated international fax line at (855) 215-1627. Then I waited. And waited. After about 11 business days, I received a fax back with my EIN assignment notice. The relief I felt that day was enormous — I had been worried the IRS would reject a form with no SSN, but they processed it without any pushback.
What the Numbers Taught Me
Here is what I learned from that experience and from helping several fellow foreign entrepreneurs go through the same process:
Processing time varies significantly by method. When I filed by fax in 2019, it took 11 business days. A colleague of mine who called the IRS international line at (267) 941-1099 in 2023 received his EIN verbally in a single phone call lasting 28 minutes. Another associate who mailed Form SS-4 to the IRS campus in Austin, Texas waited 9 weeks for a response. The method you choose dramatically impacts your timeline.
Cost should be zero if you do it yourself. The IRS charges nothing for EIN issuance. Yet I have seen third-party services charge anywhere from $50 to $500 for what is essentially filling out a one-page form. When I factored in my own time versus the quoted fees, I concluded that paying a reputable registered agent to handle both LLC formation and EIN acquisition as a bundled service was the most efficient path. The standalone EIN filing, however, costs $0 at the IRS.
Having a US registered agent address matters. My first attempt at opening a US business bank account after receiving the EIN was rejected because my LLC’s formation documents listed only a registered agent address that the bank flagged as a “virtual office.” I learned the hard way that banks like Chase and Bank of America scrutinize the physical presence of foreign-owned LLCs. This is a detail that most EIN guides skip entirely, but it cost me about three weeks of delay and a significant amount of frustration.
Step-by-Step: How to Get an EIN Without SSN in 2026
The Complete Process in 6 Steps
Below is the exact step-by-step process that works as of 2026. I have updated this based on the latest IRS procedures and my ongoing experience managing US entities as a non-resident.
Step 1: Form your US LLC first. You need a legal entity before you can apply for an EIN. Most non-US residents choose Wyoming or Delaware for their LLC formation due to favorable privacy laws and low annual fees. Wyoming charges a $100 annual report fee, while Delaware charges a $300 annual franchise tax for LLCs. Choose the state that aligns with your business needs.
Step 2: Appoint a US registered agent. Every LLC must have a registered agent with a physical address in the state of formation. This is a legal requirement, not optional. A registered agent receives legal and tax documents on your behalf.
Step 3: Download IRS Form SS-4. Go to irs.gov and download the latest version of Form SS-4 (Application for Employer Identification Number). Do not use the online EIN assistant — it requires an SSN or ITIN and will not work for most non-US residents without one of these numbers.
Step 4: Complete Form SS-4 carefully. Fill in your LLC name, the registered agent’s US address, your name as the responsible party, and your foreign passport number. On Line 7b, write your country of residence. Leave the SSN/ITIN field blank or write “Foreign” in the margin. On Line 10 for the reason for applying, check “Started new business” and describe your activity.
Step 5: Submit by fax or mail. Fax the completed form to (855) 215-1627 for a response in approximately 4 to 10 business days. Alternatively, mail it to: Internal Revenue Service, Attn: EIN International Operation, Cincinnati, OH 45999. Mail processing takes 6 to 10 weeks. You can also call the IRS Business & Specialty Tax Line at (267) 941-1099, Monday through Friday, 6:00 AM to 11:00 PM Eastern Time, but wait times can exceed one hour.
Step 6: Receive and store your EIN confirmation. The IRS will send you an EIN assignment notice (CP 575). Keep this document in a safe place — you will need it for banking, tax filing, and ongoing compliance.
What Beginners Should Do First
If this is your first time navigating US business formation, do not start with the EIN application. Start with understanding which state to form your LLC in and whether you need a single-member or multi-member structure. Your entity type affects your US tax obligations significantly. [INTERNAL_LINK_1]
As someone who holds the AFP certification and has worked in financial advisory, I always tell first-time foreign founders: get your entity structure right before worrying about the EIN. The EIN application itself is the easy part. The strategic decision — which state, which entity type, which registered agent — is where most people either save or lose thousands of dollars over the life of their business.
For most non-US residents with a straightforward online business or investment holding company, a Wyoming single-member LLC is the simplest and most cost-effective option. Wyoming has no state income tax, no franchise tax for LLCs, and strong asset protection statutes. Your total formation cost, including registered agent fees, should be between $150 and $350 per year depending on which service you use.
Common Mistakes and Pitfalls When Applying for an EIN Without SSN
The 3 Most Frequent Failures I Have Seen
- Trying to use the IRS online EIN application. This is by far the most common mistake. The IRS online assistant at irs.gov/businesses/small-businesses-self-employed/apply-for-an-employer-identification-number-ein-online requires an SSN or ITIN. Non-US residents without these numbers cannot complete the online form. If you try to enter a foreign passport number, the system will reject it. You must use the fax, mail, or phone method instead.
- Submitting Form SS-4 before the LLC is officially formed. The IRS needs to see that your entity already exists in a US state. If you send in your SS-4 before your Articles of Organization have been filed and approved by the state, the IRS may reject your application or assign the EIN incorrectly. Always confirm that your LLC formation is complete — including receiving your filed Articles back from the Secretary of State — before applying.
- Using incorrect information for the “responsible party.” The IRS requires one individual to be listed as the responsible party on Form SS-4. For a foreign-owned single-member LLC, this is you — the member. Do not list your registered agent as the responsible party unless they are actually a member or officer of the LLC. I have seen applications delayed by weeks because of this mismatch.
Real Failures I Have Witnessed (Including My Own)
Beyond my own fax-and-wait experience in 2019, the most painful mistake I witnessed happened to a business acquaintance in 2022. He was a Japanese national who had formed a Delaware LLC for an Amazon FBA business. He paid a third-party “EIN service” $399 to obtain his number. The service took his money, submitted a sloppy Form SS-4 with his name misspelled, and listed a PO Box as the principal business address — which the IRS does not accept for a responsible party’s address. The application was rejected. He then had to re-file himself, wait another 6 weeks, and lost nearly two months of selling time on Amazon. The $399 was non-refundable.
My advice from that experience: if you are going to pay someone to handle the EIN process, bundle it with your LLC formation through a reputable registered agent service. Standalone “EIN filing services” that charge hundreds of dollars for a free IRS form are, in my professional opinion as a licensed AFP, almost never worth the fee. [INTERNAL_LINK_2]
Another mistake I personally made was underestimating how important the EIN confirmation letter (CP 575) is for banking. When I tried to open a business checking account at a US bank in 2020, the bank required the original CP 575 notice — not a copy, not the online verification printout. I had misplaced my original fax and had to request a replacement (Form 147C) from the IRS, which added another 10 days to the process. Now I scan and digitally store every IRS document the day I receive it.
One more cautionary note from my experience operating a minpaku (民泊) in Asakusa, Tokyo: cross-border business structures create complex tax obligations. Having a US EIN does not mean you can ignore Japanese tax reporting if you are a Japanese tax resident. I had to coordinate with both a US CPA and a Japanese tax accountant (税理士) to ensure proper reporting. This is an area where many foreign LLC owners get into trouble — they focus entirely on the US side and forget their home country obligations.
Summary: Your EIN Without SSN Action Plan for 2026
3 Key Takeaways from This Guide
- Getting an EIN without SSN is 100% legal and straightforward. The IRS allows non-US residents to apply via fax, mail, or phone using Form SS-4 and a foreign passport number. The process costs $0 at the IRS level.
- The fastest method is calling (267) 941-1099 during business hours or faxing Form SS-4 to (855) 215-1627. Expect 4 to 10 business days by fax, or same-day by phone if you can get through. Mail takes 6 to 10 weeks and should be your last resort.
- Form your LLC and appoint a registered agent before applying for the EIN. Doing things in the wrong order is the number one cause of delays and rejections that I have seen across dozens of cases since I first went through this process in 2019.
Your Next Step: Get Started Today
If you are ready to form your US LLC and obtain your EIN without SSN, the most efficient approach is to use a registered agent service that handles both formation and EIN acquisition in one package. This eliminates the paperwork headaches, ensures your documents are filed correctly, and gives you a compliant US address from day one.
Based on my experience forming and managing US entities as a non-resident — and having made enough mistakes along the way to know what actually matters — I recommend starting with a service that has a strong track record with foreign clients, transparent pricing, and genuine human support when you need it.

Northwest Registered Agent includes a full year of registered agent service with LLC formation, provides a US business address, and has dedicated support for non-US residents navigating the EIN application process. Their formation package starts at $39 plus state fees, which is significantly more cost-effective than the fragmented approach of hiring separate services for formation, registered agent, and EIN filing.
Do not let the lack of an SSN stop you from building your US business. The process is clear, the IRS supports it, and thousands of non-US residents successfully obtain their EIN every year. Take the first step today.
