What is an EIN?

An EIN, or Employer Identification Number, is a unique nine-digit number assigned by the IRS to business entities operating in the United States. It's essentially a Social Security number for your agency, used to identify it for tax purposes. An EIN is mandatory for most agencies, especially those with employees or those operating as corporations or partnerships. Even single-member LLCs in Louisiana might need one.
