An Employer Identification Number (EIN) is a fundamental requirement for operating a US business entity such as an LLC or corporation. For non-resident entrepreneurs, one of the most common questions is whether an EIN can be obtained without a Social Security Number (SSN).
The short answer is yes. The IRS allows non-US residents to apply for an EIN without an SSN or ITIN, provided the application is completed accurately and submitted through the approved process.
This guide explains how the process works, what the IRS requires, expected processing times, associated costs, and the documents commonly needed—based on practical filing experience and real-world application scenarios.
What is an EIN and Why Does It Matters for Non-Residents?
An EIN is a unique nine-digit tax identification number issued by the IRS. It is used to identify businesses operating in the United States for tax reporting and compliance purposes.
For non-resident entrepreneurs, an EIN is typically required for:
- Opening a US business bank account
- Registering payment processors (Stripe, PayPal, etc.)
- Filing US tax returns for an LLC or C-Corporation
- Hiring employees in the United States
- Establishing a business credit profile
Unlike an SSN, an EIN is not connected to personal residency or immigration status. It is issued specifically for business entities.
Expert Insight: In most non-resident business structures, the EIN becomes the primary identifier connecting your LLC to the US tax system, banking infrastructure, and compliance records.
Can You Get an EIN Without an SSN?
Yes, you can obtain an EIN without an SSN.
The IRS specifically permits foreign applicants to apply for EINs using alternative identification methods. This includes individuals who do not live in the United States and who are not eligible for an SSN or ITIN.
Instead of an SSN, applicants generally use:
- Form SS-4 (IRS application form)
- Passport details
- Foreign mailing address
- LLC or corporation formation documents
The key requirement is that the business entity must be properly formed and clearly structured.
How to Apply for an EIN Without an SSN
There are three primary methods for applying for an EIN. However, not all options are available to non-residents.
1. Online Application (Limited Eligibility)
The IRS online EIN application system is limited to applicants who have an SSN or ITIN. Most non-residents are therefore not eligible to use this method.
2. Fax Application (Most Common Method)
This is the standard method commonly used by international founders.
Step-by-step process:
- Complete IRS Form SS-4
- Leave the SSN field blank if you do not have one
- Enter your foreign address using the correct format
- Specify your LLC or corporate structure accurately
- Fax the completed form to the IRS international office
- Wait for the EIN confirmation letter
3. Mail Application (Slower Option)
- Print and complete Form SS-4
- Mail the form to the IRS
- Wait for processing and confirmation
This method is generally used only when fax access is unavailable, as processing times are significantly longer.
Key Tip for SS-4 Form Accuracy
Important Compliance Note: The IRS does not reject EIN applications because of foreign status. Most delays occur due to inconsistent entity information or incorrectly completed SS-4 fields.
EIN Online Apply vs Non-Resident Reality
While many entrepreneurs search for “EIN online apply,” it is important to understand the actual limitations for non-residents:
| Method | Available for Non-Residents | Processing Speed | Reliability |
| Online IRS system | No | Instant | Not applicable |
| Fax submission | Yes | 3–10 business days | High |
| Mail submission | Yes | 3–5 weeks | Medium |
For non-residents, fax submission remains the most practical and widely accepted option.
How Long Does It Take to Get an EIN Number?
Processing times depend on the submission method and the accuracy of the provided documentation.
Typical Processing Timeline
- Fax application: 3–10 business days
- Mail application: 3–5 weeks
- Correctly completed applications are often processed faster
Factors that may cause delays:
- Incorrect SS-4 form details
- Missing business classification
- IRS workload fluctuations
- Inconsistent LLC documentation
Expert Insight: In practical filing situations, most properly completed non-resident EIN applications submitted by fax are processed within approximately one week.
How Much Does It Cost to Apply for an EIN?
One major advantage of EIN registration is that the IRS issues EINs free of charge.
Cost Breakdown
| Item | Cost |
| EIN issued by the IRS | $0 |
| Fax submission | $0 |
| Mail submission | $0 |
| Optional service providers | $50–$300 |
The IRS does not charge any application fee.
However, some entrepreneurs choose to work with third-party service providers for:
- Form SS-4 preparation
- Filing assistance
- Application review and handling support

Step-by-Step Real Application Workflow
Below is a practical workflow commonly followed by non-resident entrepreneurs.

Step 2: Prepare the EIN Application (SS-4)
Make sure all information matches your business formation documents exactly.
Step 3: Choose a Submission Method
Fax submission is generally preferred due to speed and reliability.
Step 4: Submit to the IRS
Send the completed SS-4 form to the IRS international fax office.

Real-World Example (Non-Resident Case)

This process is commonly used by:
- Freelancers
- E-commerce sellers
- SaaS founders
- Remote agencies
Common Mistakes That Cause EIN Delays
Many applications are delayed because of avoidable administrative issues, including:
- Incorrect legal business name
- Missing LLC formation details
- Incorrect responsible party information
- Inconsistent foreign address formatting
- Incomplete SS-4 fields
Expert Insight: IRS processing is generally straightforward when documentation is consistent and complete. Most delays are administrative rather than eligibility-related.
EIN Without SSN vs With SSN (Comparison)
| Feature | With SSN | Without SSN |
| Online application | Yes | No |
| Fax application | Yes | Yes |
| Processing speed | Faster | Slightly slower |
| Eligibility | US residents | Global founders |
| Accessibility | High | Medium |
Expert CPA Perspective
From a compliance perspective, the IRS does not distinguish between US and non-US applicants when determining EIN eligibility.
The most important factors are:
- Accurate entity classification
- Proper SS-4 submission
- Consistent business documentation
In most situations, delays are caused by form completion errors rather than eligibility restrictions.
Conclusion
Obtaining an EIN without an SSN is a standard and widely accepted process for non-resident entrepreneurs. The IRS allows foreign applicants to apply directly through Form SS-4 without requiring US residency or an SSN.
Although the process is relatively straightforward, accuracy remains critical. A properly completed application is often processed within a few business days when submitted by fax.
For international founders, an EIN serves as the foundation for establishing a US business presence, opening business bank accounts, and operating within the US tax and compliance system.
