EIN records

EIN lookup

EINs are public only where the law makes them public: companies that file with the SEC and tax-exempt nonprofits. Search those two sets here — by company name or by number — and see exactly how to find your own EIN.

What this searches

  • SEC-registered companies (EDGAR filings)
  • Tax-exempt nonprofits (IRS records)
  • No private-company EIN directory exists — we say so, not sell around it

By company name

Find a public company’s EIN

Searches SEC-registered companies whose filings disclose an EIN — sourced from EDGAR by our own pipeline, never scraped aggregators. A company that has never filed with the SEC will not appear here, by design.

By number

Check a 9-digit EIN

Format and issuing-office checks run entirely in your browser. If the number is well-formed, one server request checks the two public registries — IRS tax-exempt records and SEC filings — and reports any match. The number is not stored.

Straight answer

Why most “EIN lookup” sites can’t deliver

The IRS does not publish a database mapping EINs to businesses. An EIN becomes public in exactly two ways: a company files it with the SEC (it appears in EDGAR filings), or an organization is tax-exempt (it appears in IRS exempt-organization records and Form 990s). Every legitimate lookup — including this one — covers those two sets and nothing more. For a private company, the reliable routes are a signed W-9 from the company itself, its state registry filing (some states disclose federal IDs), or payroll/tax documents you already hold.

Your own number

Finding or recovering your own EIN

  • The CP 575 confirmation letter the IRS sent when the EIN was assigned — the canonical record.
  • Any previously filed federal tax return for the business (the EIN prints in the header).
  • Your bank: business accounts require the EIN at opening, and the bank can read it back to an authorized signer.
  • The IRS Business & Specialty Tax Line, 800-829-4933 — after identity verification they issue a replacement letter (147C). Only an authorized person can call.
