Applying for an Employer Identification Number (EIN)
An Employer Identification Number (EIN), also known as a Federal Employer Identification Number (FEIN), is a unique nine-digit number assigned by the Internal Revenue Service (IRS) to business entities operating in the United States for identification purposes. It is essential for various business activities, including opening a business bank account, hiring employees, and filing tax returns. This guide will walk you through the process of obtaining an EIN, focusing on the methods available, especially for those outside the US.

What is an EIN and Why Do You Need One?
An EIN serves as the Social Security number for your business. It's crucial for distinguishing your business from others and for tax administration. You will typically need an EIN if you:
- Operate your business as a corporation or a partnership.
- File tax returns for excise, alcohol, tobacco, and firearms.
- Operate a Keogh plan.
- Are involved with trusts, estates, real estate mortgage investment conduits (REMICs), non-profit organizations, farmers' cooperatives, or other types of organisations.
- Have employees.
- Are a bank or certain other types of organisations.
For international applicants, an EIN is often required to conduct business within the United States, open US bank accounts, or comply with US tax regulations, even if you don't have a physical presence in the country.
The Application Process: The SS-4 Form
The primary method for applying for an EIN is by completing Form SS-4, Application for Employer Identification Number. This form collects essential information about your business to assign your unique identification number. While the IRS provides detailed instructions for the form, this guide offers a breakdown of key sections, especially for international applicants.
Completing Form SS-4: A Section-by-Section Breakdown
The SS-4 form is divided into several key sections. Understanding each part is crucial for a smooth application process.
Sections 1-6: Business Name and Address
- Line 1: Legal Name of Entity – Enter the full legal name of your business as it appears on official documents. This must be in English.
- Line 2: Trade Name – If your business operates under a different name (a "doing business as" or DBA), enter it here.
- Line 3: Fiduciary, Grantor, or Executor Name – This line is for specific entity types like trusts or estates. If applicable, enter the name of the trustee, executor, or agent.
- Lines 4a-b: Mailing Address – Provide the full mailing address where the IRS can send correspondence. Ensure this is accurate and complete, including street name, number, city, state/province, postal code, and country.
- Line 5: Physical Address – If your business's physical location is different from your mailing address, enter it here.
- Line 6: Principal Business Location Country – For international applicants, clearly state the country where your business is primarily located (e.g., "France").
Sections 7a-7b: Responsible Party Information
- Line 7a: Name of Responsible Party – This should be the full name of the individual who ultimately controls, manages, or directs the entity and its tax-related affairs. For most businesses, this will be the owner, president, or managing member.
- Line 7b: Social Security Number (SSN), Individual Taxpayer Identification Number (ITIN), or EIN of Responsible Party – If the responsible party has one of these US tax identification numbers, enter it. If not, this field can often be left blank for international applicants, or you may need to consult specific IRS guidance or a tax professional.
Section 8a: Limited Liability Company (LLC) Status
If your entity is an LLC, check "Yes" for Line 8a. If you check "Yes", you will need to complete Lines 8b and 8c, which ask about the LLC's tax classification (corporation or partnership).
Section 9a: Type of Entity
Check the box that best describes your business entity type (e.g., Corporation, Partnership, Sole Proprietor, LLC, Trust, Estate, etc.). Refer to the IRS instructions for precise definitions.
Section 9b: State or Foreign Country of Incorporation/Organization
If your entity is incorporated or organized in a specific state or country, enter that information here.
Section 10: Reason for Applying
This is a critical section. You must select one reason for applying for an EIN. Common reasons include "Started new business," "Hired employees," or "Banking purposes." For international entities, "Compliance with IRS withholding requirements" might be relevant if you are subject to US tax withholding. Do not leave this blank or select "N/A."
Section 11: Date Business Started or Acquired
Enter the date your business began operations or was acquired. For new businesses, this is usually the date of formation or incorporation.
Section 12: Month the Accounting Year Ends
Indicate the last month of your business's accounting or tax year (e.g., December for a calendar year).
Sections 13-15: Additional Information
These sections may require additional details depending on your business type and activities. Consult the IRS instructions for specific guidance.
Section 16: Principal Activity of Your Business
Check the box that best describes your primary business activity. You must select one.
Section 17: Business Activity Code and Description
Provide a more specific description of your business's industry or sector. This field is mandatory.
Section 18: Previous EIN
If your business has ever been assigned an EIN before, check "Yes." Otherwise, check "No." You can only have one EIN per entity.

Signature and Date
The form must be signed and dated by the responsible party. Note that a handwritten signature is required; electronic signatures are not accepted for mailed or faxed applications. You can sign in your native language and alphabet.
Methods of Application for International Applicants
While US-based applicants can apply online, international applicants have several options:
1. Telephone Application (Fastest Method)
This is the quickest way to obtain an EIN. You can call the IRS directly:
- Phone Number: +1 (267) 941-1099 (This is a toll number).
- Hours: Monday through Friday, 7:00 AM to 7:00 PM Eastern Time.
Be prepared to provide all the information from Form SS-4 over the phone. You will receive your EIN immediately upon successful application.
2. Fax Application (Faster than Mail)
If your principal business, office, or agency is not in the United States, you can fax your completed Form SS-4 to:
- Fax Number: +1 (304) 707-9471
Include your fax number on the application. Your EIN will typically be faxed back to you within 4 business days.
3. Mail Application (Slowest Method)
You can mail your completed Form SS-4 to:
- Mailing Address:
Internal Revenue Service
Attn: EIN International Operation
Philadelphia, PA 19255
USA
Mail applications generally take approximately 4 weeks to process. If you do not provide a fax number, your EIN will be mailed to the address provided on your application.
Important Considerations for International Applicants
- Accuracy is Key: Ensure all information provided is accurate and matches your business's legal documentation. Errors can lead to significant delays.
- Responsible Party: Clearly identify the responsible party. This person will be the main point of contact for the IRS regarding your business's tax matters.
- Tax Advisor: If you are unsure about any part of the SS-4 form or the application process, it is highly recommended to consult with a qualified tax advisor or professional who specialises in international business taxation.
- No Online Application for Non-US Residents: Currently, individuals without a US Taxpayer Identification Number (SSN, ITIN, or EIN) and located outside the US cannot apply for an EIN online. You must use the phone, fax, or mail methods.
What to Do After Obtaining Your EIN
Once you receive your EIN, you will need to use it for all relevant business transactions and filings. If you are using the EIN for platforms like Amazon KDP, ensure you enter it correctly into their online tax questionnaire and submit the generated form as instructed.
