If you’re looking to verify a company’s identity, check tax documents, or perform due diligence, you might be asking: how to find a business EIN number online?
A company’s Employer Identification Number (EIN) is like its tax ID. While not all EINs are public, there are legal ways to locate one depending on the situation and your intent. Let’s explore the legitimate ways you can find a business EIN online.
What Is an EIN and Why Do You Need It?
An Employer Identification Number (EIN) is a unique 9-digit number issued by the IRS to identify a business entity for tax purposes. It’s required for:
- Filing business taxes
- Opening business bank accounts
- Applying for business licenses
- Verifying vendor or employer information
Sometimes, finding a business’s EIN is necessary for financial verification, contracts, or tax reporting.
How to Find a Business EIN Number Online
Here are the most reliable and legal methods to search for an EIN online:
1. Search SEC Filings for Public Companies
If the business is publicly traded, its EIN is often listed in its SEC filings, such as Form 10-K or Form 8-K.
- Visit https://www.sec.gov/edgar/searchedgar/companysearch.html
- Enter the company name
- Open the relevant filing and locate the EIN in the header section
2. Check the IRS Exempt Organizations Database (For Nonprofits)
Nonprofit organizations that are tax-exempt must publicly disclose their EIN.
- Go to the IRS Tax Exempt Organization Search tool
- Search by organization name
- Click on the profile to view the EIN
3. Use Third-Party Business Lookup Services
Several commercial websites aggregate public business data, including EINs when legally available. Popular options include:
- Melissa Data
- Manta
- Buzzfile
- OpenCorporates
- Nolo or EIN Finder (for paid access)
Note: These sources may charge a fee or have limited data, especially for private companies.
4. Request EIN Verification from the Company
If you’re working with a vendor or partner, the most direct approach is to ask the business for a completed Form W-9, which includes their legal name and EIN.
This is common practice for:
- Freelancers hiring contractors
- Companies preparing 1099 forms
- Vendors managing payments or tax reports
5. Hire a Professional or Legal Service
If your search is related to due diligence, M&A, or compliance, consider hiring a:
- Certified Public Accountant (CPA)
- Tax attorney
- Business formation service
These professionals may access EINs via legitimate channels not always available to the public.
Is It Legal to Find an EIN Online?
Yes—if the EIN is publicly available (such as in SEC filings or nonprofit databases), it’s legal to search and use it for informational or reporting purposes. However:
- Do not attempt to hack or extract private EINs
- Never use an EIN for fraudulent activity
Always ensure your intent and use are within legal and ethical guidelines.
Final Thoughts
So, how to find a business EIN number online? Use public records like SEC filings, IRS nonprofit databases, and trusted business directories. If you’re unable to find one through public means, request a W-9 from the company directly or consult a professional.
