How to Look Up and Verify a Company’s EIN

When a company or an entity has to file their taxes or open a business bank account, they’ll (not every entity) need to have their Employer Identification Number (EIN) ready.

EIN is a unique nine-digit taxpayer identification number assigned by the IRS. It is used for federal tax filing purposes as well as to hire employees, open a business bank account, and complete other financial/tax-related transactions. EIN is also a requirement when applying for business licenses.

Since an EIN is an important identifier for tax purposes, having the correct EIN is essential. And knowing how to look up a company’s EIN can help a business meet federal tax reporting compliance.

Is It Possible To Look Up A Company’s EIN Online?

Looking up a company’s EIN online is not easy if you don’t have the right tools since there is no centralized public IRS directory containing the EIN of every eligible company. The best and most reliable method is to request a completed Form W-9 directly from the payee.

However, there are a few public sources that can help in specific cases:

• IRS Tax Exempt Organization Search: Use this tool to lookup EIN and exemption details for eligible tax-exempt organizations. It does not cover private companies.
• SEC EDGAR filings: You can use this method to find the EIN for public companies, but the number may belong to the SEC registrant or parent company, and not the exact entity you are looking for.
• Secretary of State database: You can find the legal name, formation details of the company, and occasionally the EIN, if filed with certain states.
• Prior payer records: If a payee had already provided their EIN and legal name before, that EIN can still be used, provided that the information is not outdated.

What Type Of Businesses Need An EIN?

The IRS requires an entity or a business to have an EIN based on the business’s legal structure, federal tax classification, employees, and whether it must file certain federal tax returns.

Corporations, partnerships, tax-exempt organizations, and many LLCs need an EIN, while a sole proprietor or single-member LLC can use the owner’s SSN in certain situations, instead of an EIN.

EIN Lookup, EIN Verification, and Business Research Explained

Company EIN lookup is one part of the tax compliance process. You’ve also got EIN verification, and business research. These are also part and parcel of how to stay complaint and each of these activities serve their own different purposes. An EIN lookup helps you obtain a payee’s tax information, EIN verification confirms that the legal name and TIN match IRS records, and business research helps validate a company’s registration, tax status, or ownership.

A Safe Payer Workflow for Collecting and Verifying an EIN

When it comes to collecting and verifying EIN,

Request Form W-9 during onboarding

The best time to collect the legal name, business name, tax classification, address, exemption information, and EIN is during onboarding. Before making any reportable payments, collect a Form W-9 from the payee. Use a Form W-8 for foreign persons.

Review the form

Confirm that the information, especially the TIN and the tax classification, is accurate. Follow up with the payee if any information is missing or inconsistent.

Use the legal name for IRS TIN Matching

Always use the payee’s legal name and TIN to run a TIN Match. Using any other names can lead to incorrect matching results

Resolve mismatches and update records

If there any mismatches, get the payee to review and correct their information by requesting a new Form W-9 with the updated legal name, TIN, federal tax classification, or other information that could affect reporting.

Retain an audit trail

Document everything, including Form W-9, the validation result, correspondence, and filing records. Having documentation helps in case there are audits later on.

The Confusion Between A Legal Name & DBA

Legal name and DBA can cause confusion. They are generally used interchangeably, and sometimes a company may operate under a trade name or DBA that differs from the name associated with its EIN. The DBA is a public-facing business name, but it is not always the name the IRS uses for tax reporting. For matching purposes, payers need to use the taxpayer name reported on Line 1 of Form W-9.

Let’s list down some of the most common legal-name and entity-classification traps:

• Using an LLC name when the owner is the reportable taxpayer
• Using a parent EIN for a subsidiary
• Reusing an EIN after a merger or ownership change
• Treating a contact person as the payee
• Relying on state registration as proof of federal identity
• Combining related entities

What to Do When the EIN and the Legal Name Do Not Match

Even after obtaining an EIN, discrepancies can occur if the legal name, entity type, or taxpayer information is incorrect. However, a failed match doesn’t mean that the company is fraudulent or unregistered. It is a warning that the submitted combination may be inaccurate.

When a name and TIN combination does not match IRS records, follow these steps to rectify the problem:

• Recheck the EIN and look for any transposed, missing, or duplicate digits. An EIN has to contain nine numeric digits.
• Confirm the legal name is the same as reported in Form W-9 Line 1. Line 1 shows the legal name, while Line 2 is the trade or DBA name.
• Request a corrected Form W-9 from the payee to recertify its information if the existing form is outdated, or inconsistent.
• After receiving corrected information, resubmit the revised name-and-TIN combination to run another TIN match.

Missing TINs, CP2100 Notices, and Backup Withholding

Even after following the steps to rectify any EIN and legal name match issue, if there are still mismatches after filing returns, the IRS may issue a CP2100 or CP2100A notice. These notices are sent to payers sent to inform them that one or more name-and-TIN combinations reported do not match IRS records.

When you receive a notice, you must follow the B-notice process where you review the affected account, contact the payee for updated documentation, and track whether backup withholding must begin or continue. Backup withholding applies when a payee fails to provide TIN, uses an incorrect TIN, or does not provide a required certification. In that case, instead of paying the full amount to the payee, the payer withholds 24% of the payment and deposits that amount with the IRS.

Note: A pre-filing mismatch alone is not an automatic reason to start backup withholding. Missing-TIN, incorrect-TIN, certification, and B-notice rules determine the required action.

A Checklist For Secure EIN Management and Pre-Filing Control

• EINs and W-9 records are sensitive tax information. Always collect Form W-9s from payees through a secure, encrypted method
• Not everyone should have access to sensitive payee information. Use role-based permission to restrict access.
• Keep both current and previous Form W-9 as well as TIN search results, any filing acknowledgements, and other documentation.
• Review inactive vendor records and duplicate records before making new payments and preparing information returns.
• Use an eFiling platform like Tax1099 for vendor EIN validation. Collect taxpayer information through a secure Form W-9 workflow and verify TIN using real-time TIN Matching.

Real-Life Scenarios

1. A payer cannot find the vendor’s EIN online

The correct action is to request a Form W-9 from the vendor and run IRS TIN matching to validate the information before its used for filing.

2. An invoice shows a DBA name while the W-9 lists a different name

Use the name listed on the W-9 Line 1 to verify business EIN. In this case, the name listed on the W-9 is BDM Holdings LLC.

3. A vendor lists the LLC name but provides the owner’s TIN

Review the completed Form W-9 before filing and confirm the owner and disregarded-entity details on Line 1 and Line 2 of the form.

4. A company’s legal name and EIN fail TIN Matching

Do not automatically assume fraud or file immediately. Review the data once more and request a corrected W-9.

5. A payer receives CP2100 after filing a Form 1099

Follow the applicable B-Notice procedures and begin or continue 24% backup withholding when required.

FAQs

1. Can a payer look up a private company’s EIN online?

There is no universal public IRS directory for private-company EINs. To lookup a company’s EIN online, a payer should request Form W-9.

2. What is the safest way to collect a company EIN?

The safest way to collect a company EIN is to use a secure Form W-9 process that captures the legal name, business name, classification, address, TIN, and applicable certifications.

3. Does TIN Matching confirm that a company is legitimate?

No. TIN Matching is used to validate name-and-TIN combination. It does not confirm ownership or legitimacy.

4. Should a payer match the DBA or legal name?

Always match the legal name used on Line 1 of Form W-9. A DBA may not replace the legal name.

5. What happens when a company refuses to provide Form W-9?

If a company refuses to provide a Form W-9 even after multiple solicitation attempts, review whether backup withholding applies, and apply it if the payee still refuses or fails to provide a TIN.

6. Is TIN Matching mandatory before filing Forms 1099?

TIN matching is voluntary pre-filing control. It is not mandated by the IRS. But running a TIN Match before filing can help reduce filing errors, penalties, and IRS notices.

7. When should a company EIN be revalidated?

An EIN should be revalidated during onboarding, after W-9 has been updated, before filing season begins, or after discovering a mismatch.
