Identity Graph: MAID-to-HEM & Device Resolution

MAID-to-HEM identity resolution for onboarding and measurement. Evaluate match rates, refresh cadence, and compliance. Request a matched sample.

MAID-to-HEM and cross-device resolution

The GSDSI identity graph links mobile advertising identifiers (MAIDs) and hashed emails (HEMs) to support privacy-safe onboarding, measurement, and cross-channel activation. Enterprise buyers evaluate identity graphs on measurable match rate, refresh cadence, decay behavior, and documented compliance posture — not on deck averages.

Common buyer workflows

Audience onboarding (CRM → addressable identifiers) for DSP and CTV activation.
Cross-channel measurement joins (exposure → outcome) without walled-garden lock-in.
Householding and dedupe, including suppression lists and identity hygiene.
Identity stitching across web, mobile, and CTV where identifiers fragment.

Start with the MAID feed, then review related resources on identity-graph economics and decay in the GSDSI resource library.

MAID Data Feed (Mobile Advertising IDs) ~200M+ US MAID-to-HEM linkages and 700M+ international IDs across 150+ countries. Daily refresh. The backbone of privacy-safe cross-device identity resolution.
Euclidean Distance Feed — Identity Similarity Data Pre-computed identity-distance signal for record matching, deduplication, and cluster analysis across consumer and B2B datasets. Methodology brief on request.
Core Email File — 314M Verified, Identity-Linked 314M single-match and 585M multi-match verified emails. Identity-linked and deliverability-tested. Replace decayed CRM lists with fresh, compliant contacts.
Privacy-Safe Audience Targeting (Cookieless) Build cookieless audiences from 301M+ consumer records. Identity-resolved, privacy-safe segments. Activate to DSPs, CTV, social, direct mail, and programmatic.
Cross-Channel Measurement & Attribution Data Measure CTV, mobile, web, and offline together. ACR + identity graph + clickstream resolved into one cross-device view. Attribution without walled gardens.
