You can find your employer identification number without a W-2 by checking documents you already have (pay stubs, 401(k) statements, prior tax returns), pulling a free Wage and Income Transcript from the IRS, or searching public filings if the employer is a public company or a nonprofit. Most people find the number in under an hour without ever contacting the IRS.
Start With Documents You Already Have
The nine-digit EIN travels with a lot of paperwork besides the W-2. Pay stubs and electronic earnings statements almost always print the employer’s legal name and federal tax ID somewhere near the top or bottom. Dig up the most recent one you can find.
Retirement account statements are another reliable source. Quarterly and annual 401(k) summaries typically list the sponsoring company’s EIN because the plan administrator uses it to categorize pre-tax contributions. Health insurance enrollment paperwork, benefits notices, offer letters, severance agreements, and employment contracts sometimes carry the number as well.
If you filed a tax return in any prior year with the same employer, that return shows the EIN exactly as it appeared on the W-2. Pull last year’s return in your tax software, as a PDF, or on paper, and look at the wage reporting section. This is often the fastest single check you can run.

The IRS keeps records of every W-2 and 1099 filed under your Social Security number. The Wage and Income Transcript shows your employer’s name, address, and full EIN for the current year and up to nine prior years.1Internal Revenue Service.

Once you’re in, select the Wage and Income Transcript for the tax year you need. Unlike some other transcript types, this one displays the complete EIN rather than a partial mask.2Internal Revenue Service. About Tax Transcripts
One catch: if you had more than roughly 85 income documents in a single tax year, the online system won’t generate the transcript and you’ll need to request it by mail.1Internal Revenue Service. Transcript Types for Individuals and Ways to Order Them
Requesting the Transcript by Mail
If the online route doesn’t work, use IRS Form 4506-T (Request for Transcript of Tax Return).

Search Public Filings
Public Companies: SEC EDGAR
If your employer is publicly traded, the EIN is public record. Go to the SEC’s EDGAR full-text search at sec.gov, enter the company name, and open the most recent Form 10-K. The cover page lists the company’s IRS Employer Identification Number alongside its principal office address.
Nonprofits: Form 990
Tax-exempt organizations file Form 990 annually, and federal law requires those filings to be available for public inspection.5Internal Revenue Service. Public Disclosure and Availability of Exempt Organizations Returns and Applications – Documents Subject to Public Disclosure The EIN appears in the heading section of every 990.6Internal Revenue Service. 2025 Instructions for Form 990 Free tools like ProPublica’s Nonprofit Explorer let you search by name and view filings instantly. This works well for former employees of hospitals, universities, and charities.
Bankrupt Employers: PACER
If your former employer went through bankruptcy, the federal courts’ PACER database can help. PACER allows searches by party name, and bankruptcy petitions typically include the debtor’s tax identification number.7PACER: Federal Court Records. What Information Is Needed to Search Court Records Using PACER There’s a small per-page fee to view documents.
Ask the Employer, a Coworker, or Your Bank
A quick call or email to the employer’s HR or payroll department is often the simplest fix. Those departments routinely handle requests for replacement W-2s and EIN verification. If you don’t have a direct contact, call the main line and ask for payroll.
When the business has shut down, a few other routes still work. Former coworkers who kept their W-2s or pay stubs from the same employer will have the same EIN you need. Your own bank may have detailed records of a deposited paycheck that display the payer’s tax information, since banks capture this data during payroll clearing.
Call the IRS if You’re Also Missing the W-2 Itself
If your employer never sent a W-2, or sent one with wrong information, call the IRS at 800-829-1040. Wait until the end of February so the employer has had time to issue the form. Have your name, address, phone number, Social Security number, dates of employment, and the employer’s name, address, and phone number ready.8Internal Revenue Service. If You Don’t Get a W-2 or Your W-2 Is Wrong
The IRS will contact your employer to request that the W-2 be sent, and it will mail you a copy of Form 4852, Substitute for Form W-2, in case it still doesn’t arrive.8Internal Revenue Service. If You Don’t Get a W-2 or Your W-2 Is Wrong
Sole Proprietors and 1099 Payers
If you worked for a sole proprietor running an unincorporated business, the tax ID on your W-2 might actually be the owner’s Social Security number rather than a separate EIN. Sole proprietors aren’t always required to obtain an EIN unless they have employees or meet other IRS criteria, though they’re instructed not to display an SSN as an EIN on returns.9Internal Revenue Service. Instructions for Form SS-4 The public database methods won’t help here. Contact the individual directly or request a Wage and Income Transcript.
Independent contractors receive Form 1099-NEC instead of a W-2, and the same general approach applies. Contact the payer first. If that fails, call the IRS at 800-829-1040 after the end of February with the payer’s contact information, and the IRS will request the missing form.10Internal Revenue Service. What to Do When a W-2 or Form 1099 Is Missing or Incorrect The Wage and Income Transcript also includes 1099 data alongside W-2 information.3Internal Revenue Service. Form 4506-T, Request for Transcript of Tax Return You still have to report the income even without the form; use your own records to estimate if you need to.
Filing With the Deadline Approaching and No EIN
If tax day is close and you still don’t have the number, Form 4852 acts as an official substitute for a missing or incorrect W-2. You estimate your wages, taxes withheld, and other compensation, and attach the form to your return in place of the W-2.11Internal Revenue Service. Form 4852, Substitute for Form W-2, Wage and Tax Statement Use pay stubs, bank deposit records, and any other paperwork to make your estimates as accurate as you can.
If the real W-2 or a corrected version arrives later and the numbers differ from what you filed, file Form 1040-X (Amended U.S. Individual Income Tax Return) to fix the discrepancy.10Internal Revenue Service. What to Do When a W-2 or Form 1099 Is Missing or Incorrect
