How to Search for a Tax Identification Number
- 1). Navigate to the U.S. Securities and Exchange Commission's EDGAR database if the company is a publicly traded company. Enter the company's name or zip code to find SEC filings (for example, 20-Fs). The EIN is usually listed on the first page of filings. This service is free.
- 2). Locate a nonprofit organization's EIN on Form 990, which may be found in the free GuideStar database. You'll need to register with an email and password to read the forms.
- 3). Find a private company's EIN number by looking on their website. It's often listed on the website because an EIN isn't as protected as an Social Security number and businesses often use it as an identifier on invoices and other paperwork.
