What is an EIN search tool?
What is an EIN search tool?
An EIN search tool helps teams validate a submitted Employer Identification Number (EIN), Taxpayer Identification Number (TIN), and business name against IRS records. Teams use it to catch mismatches early, reduce the risk of onboarding fraudulent businesses, and decide when an application needs more review. Middesk validates the submitted tax ID and business name, then connects the result to the broader KYB record. Teams can add more layers of information, including Secretary of State filings, screening, or monitoring, without starting over in another workflow.

If your current approach is one of these, it's worth understanding the gaps before your next audit — or your next fraud case.
01
EIN / TIN validation
Does this tax ID belong with the submitted business name?
02
Name variations
Is the mismatch caused by a legal-name, DBA, abbreviation, or formatting difference?
03
Business registration
Does the business also appear in SOS records?
04
Risk screening
Should watchlist, adverse media, or PEP screening be ordered?
05
Documents
Are formation or good-standing documents needed for review?
06
Monitoring
Should changes after approval trigger a new review?

What makes Middesk's EIN search tool different?
Middesk validates submitted tax IDs in the context of business verification. Teams can move from tax ID validation into registration checks, screening, documents, and monitoring without starting over in another tool.
Edge cases make KYB hard. We had significant fraud at the end of last year because our previous solution missed basic signals.
For example, the applicant name didn't match the officer name on the state registration, and the applicant email didn't match what was publicly listed on the business website. We were auto-approving businesses that should have gone to manual review. It cost us tens of thousands of dollars.
