Employer Identification Number (EIN)
Securing an Employer Identification Number (also known as a Federal Tax Identification Number) is the first thing that needs to be done since many other forms require it. The fastest way to apply for an EIN is online through the IRS website or by telephone. Applying by fax and mail generally takes one to two weeks. Note that effective May 21, 2012, you can only apply for one EIN per day. The previous limit was 5.
