Can I Verify a Tax ID Number?
Yes, you can verify a Tax ID Number (TIN or EIN) under certain circumstances using official tools. A Tax Identification Number (TIN) is issued by the IRS to individuals or entities for tax purposes. When dealing with businesses, this is typically an Employer Identification Number (EIN).
Why Would You Need to Verify a Tax ID?
Verifying a TIN or EIN may be necessary for:
- Confirming a vendor’s business legitimacy
- Ensuring tax reporting accuracy (e.g., 1099 forms)
- Avoiding fraudulent business dealings
- Complying with IRS backup withholding rules
How to Verify a Tax ID Number
1. IRS TIN Matching Program (For Businesses Only)
If you’re a paying business entity filing 1099 forms, you can use the IRS TIN Matching Program to verify:
- TIN and legal name match
- Validity of a vendor’s tax ID
You must register with the IRS e-Services portal to access this tool.

2. Check EIN for Public Entities
You can search for an EIN for nonprofits and public businesses via:
- IRS Exempt Organizations Select Check
- EDGAR (SEC Filings) for publicly traded companies
3. Third-Party EIN Lookup Tools
Some companies offer paid EIN lookup services, especially for business credit checks and vendor validation. Use them cautiously and verify credibility.
Can Individuals Verify a TIN?
No, individuals cannot directly verify another person’s TIN due to privacy laws. Only authorized entities, such as employers or financial institutions, can use IRS tools for verification purposes.
Important Note
The IRS will not verify an EIN by phone unless you’re the authorized party on record. If you lost your EIN, you can:
- Check your EIN confirmation letter
- Look at prior tax filings
- Call the IRS Business & Specialty Tax Line at 800-829-4933
Final Thoughts
So, can I verify a Tax ID Number? Yes—if you’re authorized and using it for legitimate, IRS-approved reasons. If you’re a business owner dealing with contractors or vendors, proper verification protects you from penalties and ensures accurate tax reporting.
