New Checkers: KYB
Two new checkers are now available in the Identity — KYB category, adding business entity validation and corporate affiliation to the ID Dataweb platform's checker library.
KYB Checker
Compares submitted business attributes against IRS records, Secretary of State registries, and watchlist databases. Returns assertions covering overall KYB match quality, business risk rating (both on an A–F scale), business name and address matching, watchlist screening, and – when a TIN/EIN is submitted – live IRS verification confirming the EIN matches their records for the submitted business name. All assertions are usable in policy rules.
Required inputs are business name and address. Optional inputs (TIN/EIN and website URL) unlock additional assertions – see the full documentation for input requirements, assertion keys, the A–F rating scale, and match logic details.
Employer Affiliation Checker
Designed to be used after the KYB Checker. Compares a user's email address against web presence data associated with the business submitted during the KYB flow – including social profiles and business websites – and returns match signals indicating whether the email is tied to that organization. Two assertions are returned: an exact email match and a broader domain-level match.
Note: test.EmailDomainMatch is the broader signal and is recommended for most use cases. Using test.EmailExactMatch alone can result in high failure rates. When paired with the existing Email OTP Possession Checker, these checkers create a full corporate affiliation workflow: confirm the email is tied to the business, then confirm the user controls that inbox.

Why It Matters
These checkers give organizations a way to assess business legitimacy at the point it matters most – the moment a business claims to be real and a person claims to represent it. By combining entity validation, corporate affiliation, and possession checks in a single orchestrated workflow, organizations can automate what has traditionally been a manual, fragmented process.
Neither entity validation nor affiliation alone is sufficient. The KYB Checker confirms the business exists and is in good standing; the Employer Affiliation Checker confirms the person is connected to it; an OTP Possession check confirms the person controls that inbox. Existing device, network, and behavioral risk checkers can layer on to assess the individual completing the workflow.
Common use cases include public sector benefits and program access, insurance claims and payout protection, financial services and fintech onboarding, corporate affiliation and access gating, and vendor and partner onboarding.
What You Need to Know
- U.S. businesses only – international coverage is not currently available.
- Gateway integration required – both checkers must be used with our Gateway implementation option.
- Sole proprietorship routing – sole proprietorships that don't appear in Secretary of State registries can be routed through existing PII checks instead.
- IRS maintenance windows – during rare IRS outages (typically Sundays 12:00 a.m.–4:00 p.m. ET),
link.TIN_BusinessNamereturns null (unverified). All other assertions continue to be returned.
Platform Improvements
What Changed
Endpoint security hardening – Session and configuration endpoints have been updated to ensure sensitive parameters are transmitted securely via POST request bodies, aligning with best practices for session data handling.
Session data cleanup – Automatic time-to-live (TTL) expiration has been enabled for session and token records, ensuring expired data is cleaned up automatically.
Why It Matters
The endpoint updates strengthen how session data is handled in transit. The TTL update improves storage efficiency and data hygiene by preventing expired records from accumulating.
What You Need to Know
- These changes require no action on your part.
- No downtime is associated with either update.
- Active sessions and in-flight transactions are not affected.
