The Employer Identification Number of a for-profit business can be verified for free using the Electronic Data Gathering, Analysis and Retrieval system. EIN numbers for non-profit companies can be found using the Melissa Data service. Authorized company personnel can verify EIN numbers through the Internal Revenue Service.
The EDGAR system is maintained and managed by the U.S. Securities and Exchange Commission. All domestic and foreign companies that do business in the U.S. are required by law to file specific forms with the SEC. Several of these forms contain a company's EIN number, including the 8-K, 10-K and 10-Q reports. Anyone can access and download the information for free by accessing the agency's website. The search tool works easier the more information about the company the user has, such as the business name, address, telephone number, state of incorporation, Central Index Key number and Standard Industrial Classification code.
Melissa Data is designed to provide important information about non-profit organizations to individuals. Users can search for business information by company name, ZIP code or tax ID. The search results provide an EIN number for the organization.
If a company has lost or misplaced its EIN number and needs to verify it, the IRS can provide that information, as long as the interested party can demonstrate that it is an authorized official of the company.
