How to Get a Tax ID Number Without a US Address

If you're forming a US LLC from Pakistan, India, the UAE, or anywhere outside the United States, you'll hit this question almost immediately: how do you get a US tax ID number if you don't have a US address? It feels like a chicken-and-egg problem — you need the tax ID to run your business, but every form seems to assume you're already sitting in an American office.

You don't need a physical US address to get a tax ID number. The IRS allows non-residents to apply for an Employer Identification Number (EIN) using a foreign address, a registered agent's address, or a compliant virtual business address, and you can apply by fax, mail, or through the IRS International Applicant phone line — no Social Security Number required. This guide walks through exactly how the process works, what address options actually satisfy the IRS, and the mistakes that slow non-resident applicants down the most.

What Is a Tax ID Number (And Which One Do You Actually Need)

"Tax ID number" is one of those umbrella terms that trips people up because it can mean several different things depending on context. For a non-resident forming a US LLC, the tax ID you're almost always after is the EIN (Employer Identification Number) — a nine-digit number issued by the IRS that identifies your business for tax, banking, and payment processing purposes.

It's easy to confuse EIN with a few other IDs:

• EIN — for your business entity (your LLC). This is what banks, Stripe, Wise, and Payoneer will ask for.
• ITIN (Individual Taxpayer Identification Number) — for you personally, if you ever need to file a US individual tax return and don't qualify for an SSN.
• SSN (Social Security Number) — issued only to US citizens and certain residents. Non-residents don't need one to run a US LLC.

If you're still unsure which of these applies to your situation, our detailed comparison of EIN vs ITIN for a US LLC breaks down exactly when you need one, the other, or both. For most non-resident LLC owners simply trying to open a business bank account or a payment gateway, the EIN is the one that unlocks almost everything.

Do You Really Need a US Address to Get an EIN?

No — and this is the single biggest misconception that stops non-resident founders before they even start. The IRS's own Form SS-4 (the EIN application form) has a field for a foreign address, and international applicants are explicitly supported through a dedicated phone line for exactly this reason.

What the IRS does need is a valid mailing address where your EIN confirmation documents can be sent, and in most cases, a designated responsible party — the person legally responsible for the LLC. That mailing address does not have to be a US residential address. It can be:

1. Your home address in your own country
2. A registered agent's address in the US
3. A compliant virtual business address service

Each of these has trade-offs, which we'll cover next.

Address Options for Getting an EIN Without Living in the US

Option 1: Use Your Foreign Home Address

This is technically the simplest option. The IRS will accept a foreign address on Form SS-4, and many non-residents successfully get their EIN this way. The downside is that your confirmation letter and any future IRS correspondence will be mailed internationally, which can mean longer delivery times and a higher chance of something going missing in transit.

Option 2: Use a Registered Agent's Address

Every US LLC is legally required to have a registered agent with a physical address in the state of formation, so this address is already part of your business infrastructure. Many non-resident owners use their registered agent's address as the mailing address on their EIN application, since it's a stable, professionally maintained US address that's less likely to trigger delivery issues. If you haven't set this up yet, our guide on choosing a registered agent for your LLC explains what to look for and how this piece fits into your overall compliance.

Option 3: Use a Virtual US Business Address

A virtual business address service gives you a real US street address (not a PO Box, which the IRS and most banks reject) that can receive and forward mail on your behalf. This is often the most practical middle ground for non-residents — professional, permanent, and not tied to a physical office you don't have. We cover exactly what qualifies and what doesn't in our breakdown of US virtual business addresses for LLCs.

Whichever option you choose, consistency matters more than which one you pick. Use the same address across your EIN application, your LLC formation documents, and your bank or payment gateway applications. Mismatched addresses are one of the most common triggers for delays and rejections down the line — something we've seen repeatedly in the common reasons EIN applications get rejected.

Step-by-Step: How to Apply for an EIN Without a US Address

Here's the practical process, in order.

Step 1: Form your LLC first. You cannot apply for an EIN before your LLC is officially registered with the state. Have your Articles of Organization or Certificate of Formation ready, since the IRS will ask for your legal business name and formation state.

Step 2: Decide on your responsible party. This is the individual — usually the LLC owner — whose name and information go on the application. Non-residents don't need an SSN or ITIN to be listed as the responsible party.

Step 3: Choose your mailing address. Pick from the three options above. Whatever you choose, make sure it's an address you'll have reliable access to for at least the next several months, since this is where your EIN confirmation letter (CP 575) will be sent if you apply by mail or fax.

Step 4: Complete Form SS-4. The form asks for your LLC's legal name, formation state, responsible party details, business address, and the reason you're applying (typically "started a new business"). Since non-residents can't use the IRS's online EIN application, you'll need to apply through one of the alternate channels below.

Step 5: Submit your application.

• By phone: Non-US applicants can call the IRS International Applicant line directly. This is often the fastest method, and in many cases you receive your EIN on the same call.
• By fax: Fax your completed SS-4 to the IRS's international fax number. Processing typically takes about a week if a return fax number is included.
• By mail: Slowest option, often taking several weeks, but useful if phone or fax access is difficult.

Step 6: Save your confirmation documents. Once approved, you'll receive your EIN confirmation letter. Keep both a digital and physical copy — banks and payment platforms will ask for this repeatedly.

What If You Don't Have an SSN Either?

This is the other half of the puzzle for most non-resident founders, and the good news is the same: you don't need an SSN to get an EIN. The IRS application simply asks you to state that you don't have one, and the process continues normally through the phone, fax, or mail channels rather than the online portal (which does require an SSN or ITIN for the responsible party). We've written a full walkthrough of this exact scenario in how to get an EIN without an SSN, which pairs well with this guide if address and SSN concerns are both on your mind.

EIN vs ITIN: Which One Solves Your "No US Address" Problem?

It's worth pausing here because a lot of non-residents assume they need an ITIN before they can get an EIN. They're actually separate processes that don't depend on each other:

If your goal is simply to open a business bank account, get paid through a payment gateway, or file your LLC's compliance forms, the EIN alone usually gets you there. The ITIN becomes relevant only if you personally owe US tax or need to claim tax treaty benefits — something our ITIN guide for non-US residents covers in more depth, along with the difference explained further in ITIN vs SSN for LLC owners.

Why This Matters More Than It Seems

Getting your EIN right — including the address you use — has downstream effects that most first-time founders don't anticipate.

Banking depends on it. Every serious US business bank account application, from Mercury to Relay to traditional banks, asks for your EIN confirmation letter as a core document. If you're exploring banking options as a non-resident, our guide to opening a US bank account from Pakistan without an SSN shows how the EIN slots directly into that process, and our broader roundup of the best US business bank accounts compares your options once you have it.

Payment gateways depend on it. Stripe, Wise, and Payoneer all require an EIN before they'll approve a non-resident-owned LLC. If you haven't compared these yet, our breakdown of the best payment gateways for non-resident LLC owners walks through exactly what each platform expects from your EIN and business documentation.

Compliance depends on it. Foreign-owned single-member LLCs have specific IRS reporting obligations, including Form 5472 filings, which are tied directly to your EIN. Missing these can trigger significant penalties, so it's worth reviewing our guide on LLC compliance, BOI reporting, and Form 5472 once your EIN is in hand.

Common Mistakes Non-Residents Make When Applying Without a US Address

Using a PO Box. The IRS does not accept PO Boxes as a business address on Form SS-4. It has to be a street address, whether that's your home address abroad, your registered agent's address, or a virtual address service.

Applying before the LLC is fully formed. The EIN application requires your LLC's legal formation details. Applying too early, before your state paperwork is finalized, is one of the most common causes of rejection or delay — something we cover in detail in our piece on common EIN rejection reasons.

Switching addresses mid-process. If you list a foreign home address on your SS-4 but later apply for a bank account or Stripe account using a different registered agent or virtual address, the mismatch can trigger manual review. Decide on your address strategy early and stay consistent across every document.

Assuming online application works. The IRS's online EIN portal is only available to applicants with a valid SSN or ITIN. As a non-resident without either, you must use phone, fax, or mail — there's no way around this step.

Not planning for the LLC formation cost and timeline first. If you're still weighing where to register your LLC and what it will cost from your home country, our guides on the cost of forming a US LLC from Pakistan and registering a US LLC from India are useful starting points before you get to the EIN stage at all. And if you're forming from Pakistan specifically, it's worth reading about the most common mistakes Pakistani LLC owners make so you don't repeat them.

How Long Does It Take?

Processing times vary by application method and are subject to change based on current IRS workload, so always check the official IRS EIN application page for the latest guidance before applying. As a general pattern:

• Phone (International Applicant line): Often same-day, sometimes within the same call
• Fax: Roughly one week if a return fax number is provided
• Mail: Several weeks, and the slowest of the three methods

Given the difference, most non-resident founders who don't need to physically visit a fax machine choose the phone route when possible, simply because it removes weeks of uncertainty from the process.

Frequently Asked Questions

Can I get a US tax ID number without a US address? Yes. The IRS accepts a foreign address, a registered agent's address, or a compliant virtual business address on Form SS-4. A US residential address is not a requirement to obtain an EIN.

Do I need an SSN to apply for an EIN? No. Non-residents can apply for an EIN without a Social Security Number by using the phone, fax, or mail application methods instead of the SSN-restricted online portal.

What address should I use on the SS-4 form if I'm not in the US? You can use your foreign home address, your LLC's registered agent address, or a virtual US business address, as long as it's a real street address and not a PO Box.

How long does an EIN take to process for a foreign owner? It depends on the method: phone applications are often approved same-day, fax applications typically take about a week, and mailed applications can take several weeks.

Can a registered agent's address be used for my tax ID? Yes. Many non-resident LLC owners use their registered agent's address as the mailing address on their EIN application, since it's a stable and professionally maintained US address.

Is a virtual address enough for IRS approval? Yes, as long as it's a legitimate street address capable of receiving mail — not a PO Box. Virtual business address providers built for LLC formation are generally accepted.

Final Thoughts

Not having a US address is not the roadblock most non-resident founders assume it is. The IRS has clear, well-established pathways for foreign applicants, and the real work is less about the address itself and more about getting your LLC formation, responsible party details, and mailing address consistent across every document you submit — from your EIN application to your bank account to your payment gateway of choice.
