How Do I Check a Federal Tax Identification Number?
An Employer Identification Number (EIN), or tax ID number, is a nine-digit number assigned by the IRS to business entities in order for them to file tax returns, including reporting income and expenses. When you are in a relationship with a business, you should verify the validity of an EIN so that your tax return goes smoothly as well.
