D&B Direct+ Identity Resolution API
The Identity Resolution surface of D&B Direct+ matches an input business record — name, address, phone, email, registration number — to a single authoritative D-U-N-S Number. The API returns ranked candidate matches with confidence and match-grade indicators so applications can either auto-accept the top result above a configured threshold or surface candidates for manual review. This is the canonical entry point for master-data-management and customer-onboarding workflows because it converts noisy free-text input into a stable D&B identifier.
