Applying for an EIN number is free of charge and can be completed online. I've linked the IRS area below where you'll learn more about the application process. http://www.irs.gov/businesses/small/arti...
EINs are issued by the Internal Revenue Service and typically stay with a business for as long as the company is open. The IRS is a national agency, so even if a business relocates and has to get a new state tax ID, its EIN will stay the same. An EIN serves as an identification number for a business, similar to the way a Social Security number identifies a person. Primarily, companies use an EIN to identify themselves on income tax and employment tax returns.
