What is an EIN?
An Employer Identification Number (EIN) is a unique 9-digit number assigned by the IRS to identify business entities in the United States. It is also known as a Federal Tax Identification Number. Every foreign-owned LLC must obtain an EIN to file Form 5472.
The EIN format is XX-XXXXXXX where the first two digits (the prefix) identify the IRS campus that issued the number. Use our filing tool to enter your EIN and generate IRS-ready forms automatically.
