How can I look up a tax ID for a business?

Back to FAQs


The Internal Revenue Service issues employers a tax ID for their business. The tax ID is also known as an Employer I.D. Number (EIN). Businesses, local or state government agencies, and nonprofit organizations have to possess an EIN. The EIN is a useful number to refer to for looking up information about various businesses. You may be able to look up an Employer I.D. Number for free, but sometimes you may need to use a service that costs money. If you simply want to know your employer’s IRS EIN, just locate it on one of your W2 forms.
