What is an EIN & Why Do You Need One?
An Employer Identification Number (EIN), also known as a Federal Tax Identification Number (FEIN), is a unique nine-digit number formatted as XX-XXXXXXX assigned by the IRS to identify business entities in the United States.
You are required to obtain an EIN if your business meets any of the following criteria:
Hires Employees
Any business that pays W-2 employee wages or withholds employment taxes.
Formed an LLC or Corp
Partnerships, S-Corporations, C-Corporations, or Multi-Member LLCs.
Opens Business Banking
Commercial banks require an EIN to open dedicated business accounts and credit cards.

Protecting Your Social Security Number on Form W-9
For freelancers, independent contractors, and gig workers, getting an EIN is the best way to safeguard your identity.
When clients ask you to complete a Form W-9 before issuing payments, you can enter your 9-digit EIN in Part I instead of your personal SSN. This prevents corporate clients, accounting departments, and third parties from storing your SSN on unencrypted servers.
What to Do After Receiving Your CP 575 Notice
Once your EIN is assigned, take these immediate next steps:
- Save multiple digital copies of your CP 575 Confirmation Letter in secure cloud storage.
- Open a dedicated business checking account at your preferred bank using your EIN and LLC formation papers.
- Update your Form W-9 with your new EIN and supply it to all active clients.
