Where can I look up an EIN number?

Employer identification numbers for publicly traded companies are found on company websites for investor relations, according to WD Adkins for the Houston Chronicle. Most companies have a page for filings with the U.S. Securities and Exchange Commission. Companies are required to list EINs on the first page of filing documents.

EINs are also found in the SEC online database of all publicly traded companies, notes Adkins. Individual taxpayers can find their EIN by referring to tax documents or by calling the Internal Revenue Service, according to the IRS. An EIN is issued to anyone, including individuals, who withholds employee taxes, according to Wikipedia. It is also issued to agencies or organizations that need the number for opening financial accounts.
