# Identity Verification Data Sources ZignSec provides several **identity verification (IDV) services** that connect to authoritative registries and data providers. These services make it easier for businesses to confirm customer identities, reduce fraud, and stay compliant with KYC/AML requirements. This section of the documentation covers three available services: - [[Identity Verification (defined data sources)|Defined Data Source]] A catalog of supported registries and providers that can be queried to validate identity details. Each entry includes coverage, availability, and usage examples. - [[Sweden Identity Lookup|Identity Lookup (Sweden)]] A service tailored for the Swedish market that verifies personal identity numbers (personnummer), names, and addresses in real time against national registries. - [[Register Checks|Register Checks (Legacy)]] Older registry lookup services, still supported for existing integrations but largely replaced by the Defined Data Sources framework. ## When to Use These Services - To comply with **Know Your Customer (KYC)** and **Anti-Money Laundering (AML)** obligations. - To validate customer information against trusted registry data. - To adapt verification processes to **local regulations and data availability**.
