Federal Employer Identification Number (EIN)
The Federal Employer Identification Number (EIN) is a unique nine-digit number (00-0000000) assigned to each business entity by the IRS. Payroll providers will ask for the company's EIN in order to file and pay the company's Federal taxes.
Apply online for an EIN, or find an existing EIN:
- on IRS Form 941 (Federal business returns),
- Form SS-4 (sent by the IRS after an online application is processed),
- or by contacting the IRS.
