How to Get an EIN: Online vs. Phone vs. Mail (Processing Time)
What Is an EIN and Why You Need One
An Employer Identification Number (EIN) is a unique nine-digit identifier that the IRS assigns to businesses, nonprofits, partnerships, and other entities for tax purposes. Whether you’re launching a new business, hiring employees, or forming an LLC, you’ll likely need an EIN to open a business bank account, file tax returns, and meet legal obligations.
Method 1: Applying for an EIN Online (Fastest Option)
The IRS online application is available through their website and is generally the fastest way to get your EIN. This method is free, convenient, and allows you to apply directly from your computer.
How It Works
You’ll complete an online form with information about your business, ownership, and principal business activities. The process typically takes 10–15 minutes. Once submitted, you may receive your EIN immediately upon completion in many cases, allowing you to use it right away.
Who Can Apply Online
Applicants must be a U.S. citizen, permanent resident, or resident alien with a valid Social Security Number or ITIN. If you’re applying on behalf of a business, you’ll need authorization to represent that entity.
Best For
Online applications work well for sole proprietors, small business owners, and LLCs who want immediate results without waiting on hold or mailing documents.
Method 2: Phone Application
The IRS operates a telephone application line where representatives can walk you through the EIN process and issue your number during the call.
Processing Details
Call the IRS’s toll-free business line during business hours. A representative will ask questions about your business structure, activities, and ownership. If everything checks out, they’ll assign your EIN over the phone. You can then record or note the number for immediate use.
Advantages
Direct interaction with an IRS representative. Able to ask clarifying questions about your specific situation. Same-day results.
Best For
This method suits applicants who prefer personalized guidance, need clarification on which business category applies to them, or lack consistent internet access.
Method 3: Mail Application
The traditional mailing option involves completing Form SS-4 by hand or printing it, then sending it to the appropriate IRS address based on your location.
Processing Timeline
Mail applications take longer to process than online or phone methods. The IRS typically processes mailed applications within several business days to a few weeks, depending on their current workload and your location.
Advantages
Familiar, tangible process for those uncomfortable with digital submission. Can request a specific EIN issue date if needed for planning purposes. Works for applicants who cannot use online or phone methods.
Disadvantages
Slower processing time. Higher risk of delay due to mail delivery. Less immediate feedback if there are errors or missing information.
