EIN Finder FAQs
What is EIN Finder?
EIN Finder is a searchable database of more than seven million official U.S. business Taxpayer Identification Numbers. These nine-digit numbers are assigned by the IRS to almost all businesses operating in the United States. EINs must be included on many filings required by the U.S. government, and they also provide clear company identification in commercial transactions.
Why do customers of EIN Finder need fast, accurate access to this data?
Business Taxpayer ID numbers are required to complete many types of forms, filings and transactions. Each business entity must have a unique EIN, just as each individual must have a unique Social Security Number. EINs help to increase the security and integrity of business interactions while preventing identity theft or misrepresentation. (Note: Within large corporations, different business entities may be assigned different EINs.)
How does EIN Finder compile and update this data?
EIN Finder has created this database by scanning thousands of available public records and filings. We are constantly adding new sources of official data to supplement our listings, and our staff works continuously to verify and update existing data. EIN Finder is one of the largest databases of its kind on the Internet.
Does EIN Finder include historical information?
Yes. One of the most popular features of EIN Finder is the historical information, especially previous company addresses associated with each EIN.
Is every business in the U.S. listed in EIN Finder?
Sole proprietorships are not required to obtain EIN numbers; they may use the Social Security numbers of the proprietor for identification, if they wish. Although EIN Finder contains numbers for many proprietors who request EINs, those using Social Security numbers are not included. Also, since some trusts and estates have used different types of numbers in the past, they may not be included.
Currently, EINs are being assigned by the IRS to sole proprietors, corporations, limited liability corporations, partnerships, estates, trusts, employer benefit plans, and tax-exempt organizations – and we are capturing them as they are filed.
Is there a difference between an EIN and an FEIN?
No. Some people refer to the EIN as an FEIN because it is issued by the federal government (Federal Employer Identification Number). The IRS now uses the term EIN exclusively.
Is there a difference between an EIN and a TIN?
An EIN is one form of acceptable Taxpayer Identification Number (TIN). For individuals and sole proprietors only, a Social Security number also is an acceptable TIN. Most other types of business entities must obtain and use EINs.
