How Long Does EIN Approval Take for Non-US Residents? (2026)

If you're building a U.S. business from outside the country, one question comes up almost immediately: how long will it actually take to get your EIN? Unlike U.S. citizens who can often get an Employer Identification Number online in minutes, non-residents face a different process entirely — and the timeline depends heavily on which method you use.

This guide breaks down exactly how long EIN approval takes for non-US residents in 2026, why the process differs from the domestic one, and how to avoid the delays that trip up most international founders. Whether you're forming an LLC from Pakistan, the UK, the UAE, or anywhere else, this article walks you through the real timeline — not just the IRS's official estimate.

What Is an EIN and Why Non-Residents Need One

An Employer Identification Number (EIN) is a nine-digit number issued by the IRS to identify a business for tax purposes. Think of it as a Social Security Number, but for your company instead of you personally.

You'll need an EIN if you're:

• Forming a U.S. LLC or corporation as a non-resident
• Opening a U.S. business bank account
• Hiring employees or contractors in the U.S.
• Setting up payment processing for an Amazon, Shopify, or Stripe account
• Filing federal or state business tax returns

The catch for non-residents is simple: the IRS's fastest EIN method — the online application — is only available to applicants who already have a Social Security Number or ITIN. If you don't have either, you're automatically routed into a slower, manual process. This is one of the most misunderstood parts of U.S. business formation, and it's exactly why timelines vary so much between residents and non-residents.

If you're weighing whether you need an EIN, an ITIN, or both for your business setup, our comparison of ITIN vs EIN for U.S. LLCs clears up the difference before you start the application.

Why EIN Processing Takes Longer for Non-US Residents

Here's the core issue: the IRS's EIN online application system checks for a valid SSN or ITIN as the "responsible party" on the application. If you don't have one, the online portal simply won't let you proceed.

That means non-residents are pushed toward three alternative methods — phone, fax, or mail — each with very different processing speeds. According to the IRS's official guidance on EIN applications, foreign entities without a U.S.-based responsible party must apply using Form SS-4 through one of these non-digital channels.

This isn't a workaround or a loophole — it's simply how the system is built. Understanding this upfront helps set realistic expectations instead of assuming you'll get same-day approval like a U.S.-based applicant might.

EIN Approval Time by Application Method

Let's break down the actual timelines for each method available to non-residents.

1. EIN by Phone (Fastest for Non-Residents)

International applicants can call the IRS's dedicated international EIN line directly. If your Form SS-4 is filled out correctly and you can answer the IRS representative's questions about your business, you can often receive your EIN on the same call.

• Typical timeline: Same day, sometimes within 30–45 minutes on the call
• Best for: Applicants comfortable speaking directly with the IRS and who have all business details ready (business name, structure, responsible party details, reason for applying)
• Limitation: International phone lines have limited hours and can involve long hold times, especially during tax season

This is generally the fastest legitimate route for someone without an SSN or ITIN.

2. EIN by Fax

Faxing Form SS-4 to the IRS is the second-fastest option and is popular because it doesn't require a phone call.

• Typical timeline: About 4 business days if you include a return fax number
• Best for: Applicants who prefer written communication or can't easily get through on the international phone line
• Limitation: You need access to a fax service (many online fax services work fine), and the EIN confirmation letter (CP 575) is sent to the fax number you provide

3. EIN by Mail

Mailing Form SS-4 is the slowest option, but it's still used by applicants who don't have fax access or prefer a paper trail.

• Typical timeline: Around 4 to 6 weeks, sometimes longer during peak periods
• Best for: Applicants with no urgency and no access to fax or phone options
• Limitation: International mail delays can stretch this timeline even further

Quick Comparison Table

If speed matters to you — and for most founders trying to open a bank account or start selling, it does — phone or fax are almost always the better choice over mail.

Step-by-Step: How Non-US Residents Apply for an EIN

Here's the full process, from start to finish.

Step 1: Form Your U.S. Business Entity First

Before applying for an EIN, your LLC or corporation needs to be legally registered with a U.S. state. If you haven't done this yet, our guide on how to register a US LLC from Pakistan walks through entity formation in detail, and the same core principles apply regardless of which country you're applying from. It's also worth understanding the total cost of forming a US LLC from Pakistan before you begin, since EIN applications are just one part of the setup budget.

Step 2: Complete Form SS-4 Accurately

Form SS-4 asks for details like your business name, entity type, state of formation, reason for applying, and responsible party information. As a non-resident without an SSN or ITIN, you'll write "Foreign" in the SSN/ITIN field for the responsible party — this is standard and expected by the IRS.

Step 3: Choose Your Submission Method

Based on the comparison above, decide whether phone, fax, or mail fits your timeline and comfort level.

Step 4: Submit and Wait for Confirmation

Once submitted, you'll receive your EIN Confirmation Letter (CP 575) — by phone readout, fax, or mail depending on your chosen method. Keep this document safe, since banks and payment processors will ask for it when you open accounts.

Step 5: Use Your EIN to Open a Business Bank Account

Once you have your EIN, you can move forward with U.S. banking. If you're also exploring international banking options alongside your U.S. setup, our guide on opening a UAE bank account as a non-resident covers a parallel process many international founders go through.

Common Reasons EIN Applications Get Delayed or Rejected

Even with the right method, plenty of non-resident applications get stuck. The most frequent causes are:

1. Incomplete or inconsistent business details on Form SS-4 that don't match your LLC's state filing
2. Missing responsible party information, especially if the business structure has multiple owners
3. Using an online application by mistake, which gets rejected instantly without SSN/ITIN
4. Fax number errors — a wrong or unreachable fax number means you never receive your confirmation
5. Choosing the wrong entity type on the form, which doesn't match your actual LLC or corporation structure

For a full breakdown of what typically goes wrong and how to fix it, our detailed guide on common reasons EIN applications get rejected is worth reading before you submit.

Can You Get an EIN Without a US Address?

Yes. This is one of the most common concerns among non-resident founders, and the good news is that a U.S. address is not required to obtain an EIN. The IRS allows foreign applicants to list their home country address on Form SS-4.

That said, having a U.S. mailing address (through a registered agent or virtual mailbox service) can make ongoing correspondence with the IRS, banks, and state agencies smoother. If this is something you're considering, our dedicated guide on getting an EIN without a US address covers exactly how that works and what your options are.

EIN vs ITIN: Which Do You Actually Need First?

This trips up a lot of first-time founders, so let's clear it up:

• EIN identifies your business for tax purposes. You need this to open a business bank account, file business taxes, and legally operate your LLC.
• ITIN identifies you as an individual for tax purposes, especially if you're not eligible for an SSN. You need this if you personally have U.S. tax filing obligations tied to your business income.

The important part: you do not need an ITIN to get an EIN. Many non-residents mistakenly believe they must get an ITIN first, which delays their entire business setup unnecessarily. You can get your EIN through the phone, fax, or mail process described above without ever having applied for an ITIN.

If you do eventually need an ITIN — for example, to file a personal tax return tied to your LLC's income — our guide on the ITIN application process for non-US residents explains that process separately.

EIN Approval for Different Business Types

The EIN application process is largely the same across entity types, but a few details shift depending on your structure.

Single-Member LLC (Foreign-Owned)

Foreign-owned single-member LLCs are treated as disregarded entities by default for tax purposes, but they still need an EIN — especially for banking and to comply with Form 5472 reporting requirements. If you're operating this type of structure, it's worth reviewing our guide on LLC compliance and Form 5472 filing so you understand your obligations after the EIN is issued.

Multi-Member LLC or Corporation

These structures may need to designate one responsible party clearly on Form SS-4, even if ownership is split. If you're deciding between an S-Corp and C-Corp structure as part of your formation, our comparison of S-Corp vs C-Corp tax deadlines can help you understand how entity choice affects your broader tax timeline, not just your EIN application.

E-Commerce Sellers (Amazon, Shopify)

If your main goal is setting up a seller account, your EIN timeline directly affects how fast you can start selling. Our guide on setting up Amazon seller accounts in the USA, UK, and UAE explains how EIN approval fits into the broader account setup timeline across marketplaces.
