Product Update — April ’24
Advance Work Email Verification
We’re introducing Advance Work Email Verification, a real-time API added to our verification suite that enables organizations to reliably validate an individual’s work identity at the moment it matters—during onboarding, underwriting, access provisioning, or eligibility checks.
As employment-linked fraud, misrepresentation, and identity spoofing continue to rise, validating whether a user genuinely belongs to a claimed organization has become a critical trust and risk control. Relying on self-declared employer details or manual validation workflows is no longer sufficient at scale.
This API allows teams to programmatically verify work emails in real time—without manual reviews, offline checks, or delayed decisioning.
What the API does
Advance Work Email Verification validates a user’s work email by combining domain intelligence with official company registry data to establish whether the email is legitimately associated with the claimed employer.
The API performs the following checks in real time:
Email domain validation to confirm domain structure, legitimacy, and usability
Domain-to-company mapping using registered corporate records sourced from MCA data
Employer name matching between the user-declared employer and the legal entity associated with the email domain
Similarity scoring to quantify how closely the declared employer name aligns with the registered company name
Together, these checks allow systems to determine not just whether a work email exists—but whether it credibly represents a real employment relationship, and with what level of confidence.
What you get in the response
The API returns clear, decision-ready signals that can be directly consumed by risk, compliance, or automation workflows:
Domain validation status
Employer name match status
Similarity score between the declared employer name and the MCA-linked legal entity
Structured outputs suitable for approve, flag, review, or escalate decisions
These signals are designed to be machine-readable and audit-friendly, enabling consistent enforcement across high-volume workflows.
Where it fits
Advance Work Email Verification is built to plug seamlessly into workflows where work identity is a gating factor, including:
Digital onboarding and KYC flows
KYB and employment verification journeys
Credit underwriting and eligibility checks
Internal access provisioning and role-based controls
Partner, vendor, and enterprise user validation
The API is stateless, real time, and designed for scale—making it suitable for both customer-facing and internal trust workflows.
Why this matters
Work identity validation has moved from a secondary check to a core trust requirement across lending, insurance, SaaS, and enterprise platforms. Fraudulent employment claims directly impact credit decisions, pricing models, eligibility criteria, and access controls—often surfacing only after losses or audits.
This shift is already visible across the ecosystem. Even large professional networking platforms have introduced work email verification to curb impersonation, resume fraud, and false employment claims.
Advance Work Email Verification brings the same level of rigor into your systems—programmatically, in real time, and at enterprise scale—without adding operational overhead.
Key benefits
Eliminate manual employer and email validation checks
Detect false or inflated employment claims early in the journey
Strengthen trust signals tied to work identity
Enable faster, automated, and consistent decision-making
Improve compliance posture and audit readiness
Tartan helps teams integrate, enrich, and validate critical customer data across workflows, not as a one-off step but as an infrastructure layer.
