For non-US companies looking to do business in the United States, opening a US bank account, hiring employees, or complying with IRS requirements, obtaining an Employer Identification Number (EIN) is essential.
In this guide, we’ll walk you through the EIN application process step-by-step, specifically for foreign businesses.
1. What is an EIN Number?
An EIN Number (Employer Identification Number) is a 9-digit tax identification number issued by the Internal Revenue Service (IRS).
It works like a “business Social Security Number” for your company, and it is used for:
- Filing US tax returns
- Opening a US business bank account
- Hiring employees in the US
- Establishing credit for your business
Even if your company is based outside the United States, you may still need an EIN.
2. Why Non-US Companies Need an EIN
Non-US companies often need an EIN for these situations:
- Selling on Amazon, Shopify, or eBay US
- Working with US payment processors like Stripe or PayPal
- Investing in US property or partnerships
- Complying with IRS reporting requirements
Without an EIN, many US financial institutions won’t allow you to open accounts or process transactions.
3. Step-by-Step EIN Application Process for Non-US Companies
Step 1: Determine if You Need an EIN
If your company is engaging in any US-based business activity, you likely need an EIN.
Step 2: Prepare Required Information
You will need:
- Legal company name (exact as registered in your country)
- Company address (can be outside the US)
- Responsible party’s name and identification (passport is fine for non-US persons)
- Type of entity (LLC, Corporation, Partnership, etc.)
- Reason for applying (“Comply with IRS requirements” or “Banking purposes”)
Step 3: Complete Form SS-4
The IRS Form SS-4 is the application form for an EIN.
Key points for non-US companies:
- On line 7b, enter “Foreign” if you do not have a US Social Security Number (SSN) or ITIN.
- Use your foreign business address in the relevant fields.
Step 4: Submit the Application
Non-US companies cannot apply for an EIN online. You must apply by:
- Fax: Send the completed SS-4 to +1 855-215-1627 (if you have a US fax number) or +1 304-707-9471 (international fax)
- Mail: Send to Internal Revenue Service, Attn: EIN Operation, Cincinnati, OH 45999
- Phone (International): Call +1-267-941-1099 (Monday–Friday, 6 a.m. to 11 p.m. US Eastern Time)
Step 5: Receive Your EIN
- By fax: Usually within 4 business days
- By mail: May take up to 4–6 weeks
- By phone: You may receive the EIN immediately after the interview
4. Common Mistakes to Avoid
- Leaving fields blank on Form SS-4
- Using a US address without authority
- Applying online as a foreign entity (foreign companies must use fax, mail, or phone)
- Not keeping a copy of your EIN Confirmation Letter (CP 575)
5. Final Tips for EIN Application
- Keep a digital and printed copy of your EIN confirmation letter
- Use the EIN on all IRS-related forms
- If you change your business structure, you may need a new EIN
- Consider using a professional EIN application service if you want to avoid mistakes
