EIN Number for Non-Residents -

Starting a US company from abroad has never been easier. A few clicks and a filing fee later, you can have a Wyoming or Delaware LLC on paper. Then comes the step that trips up almost every foreign founder: the EIN. You open the IRS website, start the application, and hit a wall because it asks for a Social Security Number you do not have.

If that sounds familiar, take a breath. Getting an EIN number as a non-resident is entirely possible, it is free, and thousands of international entrepreneurs do it every year. The process is simply different from the one Americans follow. This guide explains what an EIN is, why you need one, the three ways to apply from outside the United States, how to complete Form SS-4 correctly, and what to do once your number arrives.

With AccurixBooks, you can enjoy a stress-free EIN application process and stay focused on growing your business while we handle the process for you. Whether you’re a non-US resident starting a new LLC or need an EIN for your existing US business, we’re here to guide you every step of the way. Let AccurixBooks simplify the process so you can focus on what matters most: growing your business.

What Is an EIN, and Why Do Non-Residents Need One?

An Employer Identification Number (EIN) is a nine-digit number, written like 12-3456789, that the IRS assigns to businesses. The easiest way to think about it is as a Social Security Number for your company. It identifies your business to the IRS and to almost every institution that deals with it.

Even if your company has no employees and a modest turnover, you will most likely need an EIN to:

Open a US business bank account or an online business banking account
Receive payments through US processors such as Stripe or PayPal
Sell on marketplaces like Amazon, which collect tax information from sellers
File the tax forms your company is required to file with the IRS
Hire employees or pay US-based contractors
Build credibility with American clients, vendors, and partners who expect a proper tax ID

For non-residents there is one more reason. A foreign-owned US LLC has annual reporting obligations, and those filings are tied to the company’s EIN. Without one, you cannot file them, and you cannot run a compliant business.

Can a Non-Resident Really Get an EIN?

Yes. The IRS does not require US citizenship, US residency, a Social Security Number, or an ITIN to issue an EIN. What it does require is a genuine reason for the number, usually a US entity such as an LLC or a corporation, and a “responsible party” who can be named on the application.

The responsible party is the individual who ultimately owns, controls, or manages the entity and decides what happens to its funds and assets. For a single-member LLC, that is you. For an LLC with several members, it is typically the principal owner or the manager.

When the responsible party has no SSN or ITIN, you simply write “Foreign” on the line that asks for it. That small detail is the key that unlocks the whole process, and we will come back to it in the Form SS-4 section.

EIN vs. SSN vs. ITIN: Clearing Up the Confusion

Many first-time founders mix these three numbers up, and the confusion leads to wasted time and money. Here is the short version.

Number	Who it is for	What it is used for
SSN (Social Security Number)	Individuals authorized to live or work in the US	Employment, personal taxes, benefits
ITIN (Individual Taxpayer Identification Number)	Individuals who must file a US tax return but cannot get an SSN	Personal US tax filing only
EIN (Employer Identification Number)	Businesses and other entities	Business banking, business tax filings, hiring, payment accounts

Two points are worth remembering. First, you do not need an ITIN to get an EIN. Second, an EIN is not a substitute for an ITIN. If you only own a US LLC and have no personal US tax return to file, you probably never need an ITIN at all. Do not pay for one just because a website suggested it.

What You Need Before You Apply

Preparation is what separates a ten-minute phone call from a rejected application. Gather the following before you start.

A legally formed entity. The IRS expects the company to exist. Wait until the state has confirmed your LLC’s formation and you hold your Articles of Organization or equivalent certificate.
The exact legal name. It must match the state record letter for letter, including “LLC” or “Inc.” Name mismatches are one of the most common causes of problems later with banks.
An address. The IRS accepts foreign mailing addresses. Some founders also list a US address provided by their registered agent or a virtual mailbox service, which can make receiving IRS mail simpler.
Details about the responsible party. Full legal name and role in the company. If you have no SSN or ITIN, you will enter “Foreign”.
Basic business information. The state where the entity was formed, the date it was formed, the number of members, the type of activity, and the month your accounting year closes (December for most small businesses).
A signature. The form must be signed by an authorized person, usually the owner, member, or manager.

Take ten minutes to write these items down. Having them in front of you makes every application method faster.

Why You Cannot Simply Apply Online

The IRS offers a free online EIN application, and for US residents it is the fastest route, often finishing in minutes. Unfortunately, that tool requires the responsible party to have a valid SSN, ITIN, or existing EIN. Most non-residents have none of these, so the online route is closed to them.

That leaves three options: phone, fax, and mail. Each has its place.

Three Ways to Apply for an EIN From Outside the US

Option 1: Apply by Phone

Phone is the fastest method for most international applicants. The IRS operates a dedicated international line, +1 267-941-1099. It is not toll-free, so check your provider’s rates before calling. At the time of writing, it is staffed Monday to Friday, roughly 6 a.m. to 11 p.m. Eastern Time.

Have a completed Form SS-4 in front of you and read from it. The representative will ask the questions on the form, and if everything is in order, they can issue your EIN during the call. Write the number down immediately and double-check each digit with the agent.

A few practical tips make the call smoother:

Call at the start of the US business day, when lines tend to be quieter.
Be patient. Hold times can be long and calls sometimes drop, so keep your documents handy.
The person calling must be authorized to receive the EIN and to answer questions about the entity.
If the agent asks you to fax or mail the signed form instead, follow their instructions.

Option 2: Apply by Fax

If you prefer a paper trail or dislike phone calls, fax is a solid choice. Complete and sign Form SS-4, then send it to the IRS international fax number, 304-707-9471. Include a return fax number or a way to reach you so that the IRS can send the confirmation back.

Processing typically takes around four business days, though it can be longer in busy periods. Many founders use an online fax service, which works well as long as the transmission is clear and every page is legible.

Option 3: Apply by Mail

Mailing is the slowest route but works when nothing else does. Send your signed Form SS-4 to:

Internal Revenue Service Attn: EIN International Operation Cincinnati, OH 45999 USA

Allow roughly four to six weeks for processing, plus transit time in both directions. Because international postal delays are unpredictable, mail is best treated as a last resort.

Quick Comparison

Method	Typical speed	Best for
Phone	Same day, often during the call	Founders who want the number fast
Fax	About 4 business days	Applicants who want a written record
Mail	About 4 to 6 weeks	Situations where phone and fax are not possible

Phone numbers, fax numbers, and timelines are the kind of details the IRS updates from time to time, so confirm them on the official IRS page for international EIN applicants before you apply.

How to Fill Out Form SS-4 for a Non-Resident

Form SS-4, the Application for Employer Identification Number, looks intimidating but is only one page. Here is how foreign applicants typically approach the main lines.

Line 1, legal name. Enter the company name exactly as it appears on your formation documents.
Line 2, trade name. Fill this in only if the business operates under a different name (a DBA). Otherwise leave it blank.
Lines 4a and 4b, mailing address. Provide the address where you want IRS correspondence sent. Foreign addresses are accepted.
Lines 5a and 5b, street address. Complete this only if it differs from your mailing address. The IRS does not accept a PO box here.
Line 6, county and state of principal business. Use the state of your US entity, or follow the form instructions for foreign locations.
Lines 7a and 7b, responsible party. Enter your full name on line 7a. On line 7b, where the form asks for an SSN, ITIN, or EIN, write “Foreign” if you have none.
Lines 8a to 8c, LLC details. Confirm that the entity is an LLC, enter the number of members, and answer whether it was organized in the United States (yes, if it was formed in a US state).
Line 9a, type of entity. Classification depends on your structure. A multi-member LLC taxed as a partnership generally checks Partnership, while single-member LLCs are treated differently. Read the IRS instructions for this line carefully, or ask a professional, because a wrong classification can create headaches later.
Line 10, reason for applying. Most applicants select “Started new business” and describe the type, for example “Single-member LLC providing consulting services.”
Line 11, date business started. Use the formation date of the LLC.
Line 12, closing month of accounting year. December is the usual answer.
Line 13, number of employees. Enter 0 if you do not expect to hire in the next twelve months.
Lines 14 and 15. Leave these blank unless you expect to owe employment taxes.
Line 16, principal activity. Pick the category closest to what you do. “Other” is acceptable when nothing fits well.
Line 17, description of services or products. Keep it short and honest, for example “bookkeeping services” or “online sale of consumer goods.”
Line 18, previous EIN. Answer “No” unless the entity already has one.
Third Party Designee. If a lawyer, formation agent, or accountant is applying on your behalf, complete this section so the IRS can speak with them.
Signature. Sign, print your name, and add your title such as Owner, Member, or Manager. An unsigned form will be rejected.

Describe the business truthfully and consistently. The information you provide on this form follows your company into banks, marketplaces, and tax filings.

How Long Does It Take, and What Will You Receive?

By phone, you get the number during the call. By fax or mail, the IRS sends back a written confirmation. In all cases, the IRS issues a confirmation notice called CP 575, which serves as official proof that your EIN exists. Store it carefully, because banks, payment processors, and marketplaces often ask for it.

If you lose the notice, you can ask the IRS for an EIN verification letter, known as a 147C letter, which serves the same purpose for most institutions. It is a good idea to scan your confirmation as soon as you have it and keep a digital copy in a safe place.

What to Do After You Receive Your EIN

Getting the number is a milestone, but it is the start of your US compliance journey, not the end. Here is what usually comes next.

Open a business bank account. Keep company money separate from your personal funds from day one. Several online business banks serve non-resident founders, and most will ask for your EIN, your formation documents, and proof of identity.

Connect payment and sales platforms. Stripe, PayPal, Amazon, and similar services will ask for your EIN and may request tax forms. Non-US owners typically provide a Form W-8BEN or W-8BEN-E, depending on how the business is structured.

Understand your annual filings. A single-member LLC owned by a foreign person is generally treated as a disregarded entity for income tax purposes, but it is not off the hook. It must usually file Form 5472 together with a pro forma Form 1120 each year, generally by April 15 for calendar-year businesses. The penalty for missing this filing is significant, in the range of US $25,000, so do not ignore it even if your LLC had no income.

Keep up with state requirements. Many states require an annual report or franchise fee, and your registered agent service usually renews annually. Missing these can put the LLC out of good standing.

Maintain clean bookkeeping. Record every transaction, keep receipts, and reconcile your accounts monthly. Good records make tax filings straightforward and protect you if the IRS asks questions.

An EIN does not by itself make you a US tax resident, and your actual tax obligations depend on your country of residence, the type of income your LLC earns, and applicable tax treaties. A tax professional familiar with cross-border businesses can tell you exactly where you stand.

Common Mistakes Non-Residents Make When Applying

Most EIN problems are avoidable. Watch out for these.

Applying before the LLC exists. The IRS needs an entity to attach the number to. Form the company first.
Name mismatches. If the name on your SS-4 differs from the state record, banks may reject your account application later.
Inventing an SSN. Never enter a made-up or borrowed number. Write “Foreign” and move on.
Paying for something that is free. The IRS charges nothing for an EIN. Third-party services may charge a fee for their time and expertise, which is fine if you know it, but nobody should tell you the IRS requires a payment.
Submitting duplicate applications. Applying through several channels at once can create confusion and delays. Pick one method and wait for the result.
Choosing the wrong entity type. Misclassifying the LLC on line 9a can cause trouble with filings down the road.
Forgetting the signature. Fax and mail applications without a signature are returned.
Ignoring annual compliance. Getting the EIN is easy. Remembering Form 5472, state reports, and registered agent renewals is where many founders slip.

Should You Get Help With Your EIN Application?

The honest answer is that many founders can do it on their own. The form is short, the phone method is quick, and the IRS does not charge a penny. If you speak English comfortably and have your documents ready, you can often finish in a single call.

That said, there are good reasons to ask for support. English may not be your first language, and phone calls with IRS agents can feel stressful. You may be unsure how to classify your LLC. You may be managing time zones, work, and a business launch all at once. In these cases, a formation service or a professional acting as your third-party designee can handle the application and make sure the details are right the first time. If you choose that route, pick a provider that is transparent about its fees and tells you plainly what the IRS itself does and does not charge.
