What Is an EIN Number?
An Employer Identification Number (EIN) is a nine-digit number the IRS assigns to businesses. Its format is XX-XXXXXXX, and it works like a Social Security Number (SSN) for your business. If you've seen the term "FEIN" on state forms, that's the same number.
Knowing how to find FEIN number references is simple once you understand that EIN, FEIN, and Federal Tax ID are interchangeable terms. Some payroll systems and states label it differently, but they all refer to the same employer FEIN number assigned by the IRS.
Your EIN appears on tax returns, payroll filings like Form 941, bank account applications, and W-2 forms. For business owners managing employee pay documentation, having this number accessible is critical for compliance.
