A federal employer identification number--or FEIN--is a unique, nine-digit number that the Internal Revenue Service assigns to businesses in the United States for tax purposes, according to the U.S. Department of Labor. The IRS also assigns FEINs to nonprofit organizations such as churches, foundations or charities. Finding a company's FEIN is a moderately easy process.
Find a Federal Employer Identification Number
Search the U.S. Securities and Exchange Commission's online database to find a company's FEIN. Securities regulations require public companies to list their FEINs on all of their SEC filings, according to the U.S. Department of Labor. The SEC database allows you to search by company name, stock ticker, location or industry classification. Although you may select any of the filings listed to locate a company's FEIN, the 10-K and 20-F forms will probably be easiest to view, as the FEIN will be on the first page.
Find a nonprofit or not-for-profit FEIN by searching the online database developed by GuideStar, a nonprofit corporation that gathers and publicizes information about other nonprofits. The U.S. Department of Labor notes that GuideStar's database tracks the FEINs of nonprofit companies through their IRS filings of Form 990, a form that lists critical financial and leadership information. GuideStar's online database allows you to search by company name or location; free registration is necessary to see a company's complete details.
Locate a company's FEIN by examining any documents involved with the exchange of money. If you have done work for the company, you can find the FEIN on the forms that the company sends to employees--a form W-2 for full-time employees and a Form 1099 for part-time workers or consultants. Company invoices also usually feature a FEIN, according to the U.S. Department of Labor.
Search for a company's FEIN by using proprietary databases such as LexisNexis or the Dun & Bradstreet database. Although these databases require expensive subscriptions to use, they will feature complete company information--including FEIN--for all companies, including public, private and nonprofit.
