EIN Discovery: Accurate EIN & Name Lookups
A Failed TIN Match Tells You Something Is Wrong. EIN Discovery Tells You What's Right.
When IRS TIN matching returns a mismatch, the standard workflow is to send the vendor a generic correction request and hope they figure out what to fix. Most don't — they resubmit the same information, or submit something equally wrong, because they don't know what the IRS actually has on file. EIN Discovery closes that gap. Give it an EIN and get back the entity name associated with it in our database. Give it a company name and get back the EIN. The correction outreach that follows asks the vendor to confirm a specific name — not guess what went wrong.
The Problem With Pass/Fail Alone
IRS TIN matching confirms whether a name and TIN combination resolves. What it doesn't do is tell you what the correct information is. When a vendor record fails, your options without EIN Discovery are limited: send a generic "please resubmit your W-9" message, wait for a response that may or may not fix the problem, and repeat. At scale — hundreds or thousands of vendor exceptions after a bulk validation run — that process is slow, produces low correction rates, and often results in the same wrong data being resubmitted.
EIN Discovery gives you a reference point before outreach goes out. Instead of asking a vendor to guess what the IRS has on file, you can tell them: "The EIN you provided is associated with [entity name] in our records — please confirm whether this is correct or provide the legal name and TIN as registered with the IRS." Vendors who know exactly what to fix respond faster and submit correctly the first time.
Two Lookups. Two Use Cases.
Name Lookup by EIN
You have an EIN — from a W-9, a vendor record, a contract — and you want to know what entity name our database associates with it.
Most useful when:
- TIN matching returns a name mismatch — look up the EIN to see what name to ask the vendor to confirm
- A vendor's W-9 legal name doesn't match your contract — verify which legal name is associated with their EIN
- Onboarding a new vendor and want to independently cross-reference the name they provided
EIN Lookup by Company Name
You have a company name — from a vendor record, a contract, a referral — and you want to find the EIN our database associates with it.
Most useful when:
- A vendor record is missing a TIN — look up by name to find a reference EIN to confirm with the vendor
- A vendor provided an EIN that doesn't match — look up their name to see what EIN our database has
- Due diligence on a new counterparty — find the EIN associated with the entity name they provided
How EIN Discovery Improves Correction Rates
The difference between generic outreach and targeted outreach is response rate and accuracy. Here's how EIN Discovery changes the correction workflow:
| Step | Without EIN Discovery | With EIN Discovery |
|---|---|---|
| TIN match fails | Mismatch result — no additional context | Mismatch result + EIN lookup surfaces associated name |
| Outreach message | "Your TIN information doesn't match — please resubmit your W-9" | "The EIN you provided is associated with [specific name] — please confirm or provide your correct legal name and TIN" |
| Vendor response | Vendor guesses what's wrong — often resubmits same data | Vendor confirms or corrects a specific piece of information |
| First-submission accuracy | Low — vendor doesn't know what to fix | Higher — vendor knows exactly what's being asked |
| Correction cycles required | Often multiple rounds | Typically one |
Where EIN Discovery Makes the Difference
Post-Mismatch Correction Workflow
When a TIN matching result comes back as a name mismatch, EIN Discovery is the natural next step — look up the EIN, see what name our database associates with it, and send outreach that tells the vendor what to confirm rather than asking them to figure it out themselves.
Vendor Onboarding Verification
Before running IRS TIN matching at vendor onboarding, use EIN Discovery to cross-reference the name and EIN a vendor provided. If the lookup surfaces a different name for that EIN, resolve the discrepancy before the vendor record is created — not after the first 1099 flags it.
Contract Counterparty Verification
Legal and procurement teams can cross-reference the entity name in a contract against what our database associates with the counterparty's EIN before execution — catching DBA names, missing entity suffixes, and legal name discrepancies before they become a problem.
High-Value Payment Verification
Treasury teams releasing large ACH or wire payments can use EIN Discovery as an additional out-of-band identity check — independently cross-referencing the legal entity name on the payment instruction against our database before funds move.
Vendor Master Cleanup
Running a bulk TIN validation against a vendor master that hasn't been systematically validated produces an exception report full of mismatches. EIN Discovery helps prioritize and inform that remediation — looking up EINs for name mismatches in bulk to generate targeted correction requests for the full exception population.
Ghost Vendor & Fraud Detection
A vendor record with an EIN that doesn't associate with any known entity in our database is a signal worth investigating — ghost vendors created with fabricated EINs, entity impersonation, and mismatched identities all produce lookup results that raise questions before a payment is released.
EIN Discovery vs. IRS TIN Matching — Complementary, Not Competing
| Scenario | IRS TIN Matching | EIN Discovery |
|---|---|---|
| Confirm a vendor record is clean for filing | Official IRS confirmation | |
| Find the correct name after a mismatch | Returns failure result | Surfaces associated name for that EIN |
| Find the EIN for a known company name | Returns associated EIN by name | |
| Cross-reference before contract execution | Independent reference check | |
| Confirm identity before high-value payment | Validates submitted data | Additional cross-reference layer |
| Identify ghost vendors in vendor master | Invalid TIN result | No associated entity surfaced |
