Finding an employer's EIN (Employer Identification Number) can feel like you’re trying to crack a secret code. Honestly, it’s just a nine-digit number the IRS uses to track business taxes, but when you actually need it—maybe for a tax form or a background check—it’s suddenly nowhere to be found. You’d think this would be public data pinned to every company's homepage, right? It isn't.
If you’re staring at a blank box on a Form 1099 or trying to verify if a company is legit, you’ve probably realized the IRS doesn't just hand these out to anyone who asks. They’re protective. But the information is out there. You just have to know which drawer to look in.
Start With the Paperwork You Already Have
Before you go paying some "business search" website twenty bucks, look at your own desk. If you’ve ever worked for the company, the EIN is literally sitting in your email or a filing cabinet. Your W-2 is the golden ticket here. Box b. Look for it. It’s right there next to the employer’s address.
What if you’re an independent contractor? Check your 1099-NEC. The payer’s TIN (Taxpayer Identification Number), which is almost always their EIN, is usually in the bottom left or middle left section of the form.
Sometimes, even a simple pay stub has it. Some payroll providers like ADP or Gusto include the EIN on the digital PDF of your pay statement to make things "transparent," though not all companies do this. If you’re currently employed, just ping HR. They aren't going to think it’s weird. People ask for the EIN all the time for things like student loan forgiveness applications or local tax filings. It’s a standard request.
The SEC Loophole for Public Companies
If the company is big—think Apple, Walmart, or that tech firm everyone talks about on Reddit—the federal government basically forces them to make their EIN public. Publicly traded companies have to file reports with the Securities and Exchange Commission (SEC).
You want the EDGAR database. It’s a bit clunky and looks like it hasn't been updated since 2005, but it works. Look for the "Form 10-K," which is their annual report. Right there on the very first page, usually near the top under the company name, you’ll see "IRS Employer Identification No." followed by the digits. It’s public record. No paywall. No hassle.
Searching for Non-Profits
Non-profits are a different beast. Because they have tax-exempt status, the IRS requires them to file a Form 990. This form is essentially a public window into their finances, and yes, it includes the EIN.
- ProPublica’s NonProfit Explorer is a lifesaver here.
- Guidestar is another heavy hitter, though they might make you create a free account to see the full details.
- You can also use the IRS Tax Exempt Organization Search tool directly.
If you’re looking for a local charity or a massive foundation like the Bill & Melinda Gates Foundation, the 990 is your best bet. It’s all there: how much the CEO makes, where the money goes, and that elusive nine-digit number.
The Secretary of State Strategy
Maybe the company is small. Maybe it’s a local plumbing business or a boutique ad agency. They aren’t on the SEC database. In this case, you head to the Secretary of State (SOS) website for whatever state they’re incorporated in.
Now, full disclosure: not every state puts the EIN on their public search portal. In fact, many don’t for privacy reasons. But some states include the original Articles of Incorporation or annual reports as downloadable PDFs. Sometimes the EIN is tucked away in those scanned documents. If you’re lucky enough to be looking for a business in a "transparent" state, you’ll find it in seconds. If not, you might just find the registered agent’s name, which gives you someone specific to call.
When You’re a Creditor or Dealing with Legal Issues
If you’re a vendor trying to collect a debt or a lawyer doing due diligence, you might have to get a bit more aggressive. Credit reporting agencies like Dun & Bradstreet (D&B) keep files on millions of businesses. Their "D-U-N-S" number is their primary identifier, but their reports often include the EIN as well.
These reports usually cost money. Is it worth $50 to $100? Depends on how badly you need it. If you’re a business owner checking on a potential partner, that’s a small price to pay to ensure you aren't getting scammed.
Why Does This Number Even Matter?
You might be wondering why you can’t just go on with your life without it. For most people, finding an employer's EIN is the only way to finish their taxes. If you’re filing electronically and that number is missing or wrong, the IRS e-file system will spit your return back at you faster than you can click "submit."
It’s also a security thing. If you’re a freelancer, you need that EIN to verify that the person hiring you is actually a registered business and not just someone in a basement. If they won't give you their EIN for a W-9, that’s a massive red flag. Huge.
Avoid the Scams
A quick warning. If you Google "find EIN," you’re going to see a dozen ads for sites that look official but aren't. They’ll ask for the company name and then demand a credit card for the "full report."
Most of the time, they’re just scraping the same SEC and SOS databases I mentioned above. Don't pay for information that is legally required to be public elsewhere. Use the EDGAR database or the SOS office first.
Dealing with a Defunct Company
What if the company went belly up? This is where it gets tricky. If the business is closed and you can't reach anyone, your best move is to look at old records. If you ever received a paycheck from them, your bank might have a digital image of the deposited check. Sometimes, though rarely, the EIN or at least the state tax ID is printed on there.

Alternatively, if they filed for bankruptcy, the EIN will be all over the court filings. You can use PACER (Public Access to Court Electronic Records) to find these, though it does charge a few cents per page.
Summary of Actionable Steps
Stop stressing and start digging in this order:
Check your own records. W-2s, 1099s, and old pay stubs are the most reliable sources. If you have a physical copy, it’s 100% accurate for the year you worked there.
Ask the company directly. If you have a legitimate reason, HR or the accounting department will usually just give it to you. Say you're "verifying information for a financial application."
Use the SEC EDGAR search. If they're a "big" name or publicly traded, the 10-K form is your best friend. It’s free and definitive.
Try the SOS office. Search the business name in the state where they operate. Look for "Business Entity Search." Download any free documents available and scan them for the number.
Search for Form 990s. If it's a non-profit, hospital, or university, their tax filings are public. ProPublica makes this incredibly easy.
Check industry-specific databases. For example, if you're looking for a trucking company, the Department of Transportation (DOT) often has records that might lead you to the right place.
Use a business credit service. If all else fails and you have a budget, Dun & Bradstreet or Experian Business can provide the data, though it comes at a premium.
Finding the EIN is rarely about one "magic" website. It’s about following the paper trail that every business is forced to leave behind as they interact with the government and the public. Start with the free sources, stay skeptical of paid third-party lookups, and always double-check the number against an official document if you’re using it for IRS filings.
