What is an EIN?
An Employer Identification Number (EIN) is a unique 9-digit identifier assigned by the IRS to business entities operating in the United States. It functions like a Social Security Number for your business.
Format: XX-XXXXXXX (2 digits, hyphen, 7 digits)
Who Needs One: Corporations, partnerships, LLCs with employees, nonprofits, trusts, and certain sole proprietors.
Cost: Free. Always. No fees to apply or maintain your EIN.

EIN vs. SSN: Know the Difference
Using your personal SSN on business forms when an EIN is required creates compliance risk. An EIN separates your personal identity from business identity—critical for liability protection and audit defense.
The First Two Digits Matter
Your EIN’s prefix reveals which IRS campus issued it—Boston, New York, Chicago, Denver, etc. This matters for: tax filing, correspondence routing, and understanding jurisdiction for audits and disputes.
Getting One Is Easy (And Free)
Apply online at IRS.gov for immediate issuance. Don’t hire services to get your EIN—you’ll waste money on something you can do free in 15 minutes. EINs are never sold and never cost a dime.
