What Is an EIN and How to Get One for Free
An EIN (Employer Identification Number) is a unique nine-digit tax identification number assigned by the IRS to identify business entities for tax purposes. You can get an EIN completely free from the IRS through multiple convenient methods, including online application, mail, fax, or phone. Understanding what an EIN is and how to obtain one is essential for any business owner starting an LLC, partnership, or corporation.
Understanding EINs and Why You Need One
An Employer Identification Number serves as your business’s Social Security number in the eyes of the IRS. This nine-digit identifier is used to file tax returns, open business bank accounts, hire employees, and establish business credit. The format follows this pattern: XX-XXXXXXX.
Whether you’re forming an LLC, S-Corporation, partnership, or sole proprietorship, you may need an EIN depending on your business structure and activities. Even if you operate as a sole proprietor without employees, having an EIN adds a layer of privacy protection by using a business number instead of your personal Social Security number for business transactions.
The IRS assigns EINs at no cost, making it one of the few “free” government services available to business owners. However, many fraudulent third-party websites charge fees ranging from $25 to $200 for EIN applications, which is why it’s crucial to know how to apply directly with the IRS.
How to Get Your EIN for Free
The IRS provides several convenient methods to apply for an EIN without paying any fees. Here are your options:
Online Application (Fastest Method)
The fastest and most convenient way to get an EIN is through the IRS’s online EIN application at IRS.gov. The process takes approximately 15 minutes, and you’ll receive your EIN immediately upon approval. You’ll need your Social Security number or ITIN, business formation documents, and details about your business structure and activities. The online system is available 24/7 for business owners who want instant results.
Phone Application
You can call the IRS Business and Specialty Tax Line at 1-800-829-4933 between 7:00 AM and 10:00 PM EST, Monday through Friday. The phone application process typically takes 15 minutes. A representative will guide you through the application and provide your EIN immediately. International applicants who cannot use the online system often prefer this method.
Mail Application
Download and complete Form SS-4 (Application for an Employer Identification Number) and mail it to the appropriate IRS office based on your state. Processing time via mail typically takes 4-6 weeks. While slower than online or phone options, this method works well for businesses that prefer traditional documentation.
Fax Application
You can fax your completed Form SS-4 to the IRS fax number corresponding to your state. Fax applications are usually processed within 4 business days, making this a middle-ground option between online instant results and mail processing times.

FAQ: EIN Questions Answered
Do I need an EIN if I’m a sole proprietor with no employees?
No, you’re not required to have an EIN as a sole proprietor without employees—you can use your Social Security number instead. However, many sole proprietors choose to get an EIN anyway for privacy protection and to keep personal and business finances separate. Having an EIN also makes it easier to open a business bank account and establish business credit.
How long does it take to get an EIN?
Processing time depends on your application method. Online applications provide immediate results (within 15 minutes). Phone applications also provide instant results. Fax applications are processed within 4 business days, and mail applications typically take 4-6 weeks. For most business owners, the online method is the fastest and most convenient option.
Can I use a temporary EIN while waiting for my permanent one?
The IRS no longer issues temporary or conditional EINs. When you apply online or by phone, you receive your permanent EIN immediately. If you apply by mail or fax, you’ll need to wait for processing. The online application is your best option if you need an EIN quickly for banking or business purposes.
