An Employer ID Number (EIN) is an identifier used by the IRS for businesses and other entities. You can apply for an EIN using IRS Form SS-4.
Although it is primarily used for employment tax identification purposes, an EIN can also be used as a general tax number.

Then print out an application form and complete the application so you are sure you have all the information at hand.
You can apply for an EIN in one of four ways:
