An Employer Identification Number (EIN), also known as a Tax ID Number, is a unique number assigned by the Internal Revenue Service to each business that is required to file a federal income tax return. Corporations, partnerships, nonprofit organizations, religious organizations, sole proprietorships, government entities, trusts and estates all must have an EIN. There are several ways to find a business entity's EIN using only the Internet.
Access the U.S. Securities and Exchange Commission's Electronic Data-Gathering, Analysis and Retrieval (EDGAR) database to find the EIN of a public company. Click on "Search for Filings" and then "Company or fund name." You can search for companies by state, country, industry or stock ticker symbol. Enter the identifying information of your choice in the appropriate text box and click "Find Companies." Access the company's annual report by selecting "Form 10-K" or "Form 10-Q/A." The company's EIN will be listed on the first page of the document.
