Public EIN List: 500 Largest US Companies' EINs (SEC Data)

Every 1 of the 500 EINs is read by script from the SEC EDGAR submissions record of the company (data.sec.gov/submissions/CIK##########.json), which carries the same Employer Identification Number the company prints on the cover of its Form 10-K. The ranking uses the latest full-year revenue each company reported in XBRL. No number on this page is typed by hand or taken from a 3rd-party database.

Because a company that registers securities with the SEC must disclose its I.R.S. Employer Identification No. on the cover page of its periodic reports under the Securities Exchange Act of 1934, and EDGAR publishes those reports. A private company's EIN is confidential return information under 26 U.S.C. § 6103, so it appears in no public database; only the 2 disclosure regimes, SEC filings and Form 990, make an EIN public.

Amazon.com, Inc., the SEC registrant, reports EIN 91-1646860 in its Form 10-K header; it is row 1 of this list. Sellers receive their Form 1099-K from a subsidiary, Amazon.com Services LLC, whose EIN is printed on that form and is a different number. A payment or 1099 always carries the EIN of the exact legal entity that issued it, which for a large group is often a subsidiary rather than the listed parent.

Because the paying entity is a subsidiary. A group such as Walmart or UnitedHealth operates through dozens of legal entities, each with its own EIN, and the SEC header shows only the parent registrant's number. The EIN on your form is the 1 that applies to you; verify it with IRS TIN Matching, which checks up to 25 name and EIN pairs per session at $0, rather than against this list.

Quarterly. The script re-reads the SEC submissions API and the XBRL revenue frames, re-ranks the 500 companies and rewrites both this page and the CSV; the Updated date above moves on each refresh. An EIN itself never changes for the life of the entity, so a company's row changes only when it is acquired, re-domiciles under a new entity, or drops out of the top 500 by revenue.

Yes. The CSV at ein-number.com/company-ein-list.csv holds all 500 rows with 11 columns: rank, company, EIN, CIK, ticker, exchange, state of incorporation, SIC description, fiscal year end, revenue in USD and the EDGAR filings URL. It is published under a CC BY 4.0 licence; cite ein-number.com and the SEC as the source. The Dataset schema on this page points search engines to the same file.

Search SEC EDGAR by company name or ticker, open the latest Form 10-K or 10-Q, and read the I.R.S. Employer Identification No. line on the cover page; the lookup takes under 3 minutes at $0. EDGAR covers every SEC registrant since 1993, and full-text search since 2001 also finds a filing from the number alone. The steps are on the EIN search by company name page.

Reading and citing a public filing is lawful; that is what the SEC disclosure regime is for. Using another company's EIN on a tax form, a credit application or a bank account in its name is business identity theft, which the IRS treats as a crime and tracks through Form 14039-B. The lawful uses are verification: matching a W-9, confirming a payee before filing a 1099, or checking a vendor's legal identity.

Three reasons: the company is private or foreign-listed and files no US Form 10-K (no SEC header to read); it is a foreign private issuer filing Form 20-F, which often carries no EIN in the submissions record; or it reports revenue under an XBRL tag other than the 2 used for ranking. The list is the 500 largest by reported revenue among listed SEC registrants with an EIN in the header, not a list of every large employer.

An EIN is 9 digits in the format XX-XXXXXXX; the first 2 digits show the IRS campus that assigned it out of 83 valid prefixes. To check a number, find the company row here or on EDGAR and compare all 9 digits with the document in hand. A match confirms the parent registrant's EIN; a mismatch most often means a subsidiary issued the document, not a fake. The IRS charges $0 to confirm a pair through TIN Matching.
