Legal ID

Legal identifiers are the foundation of corporate trust and compliance—yet they often vary in format and structure from one country to another. Delpha's Legal ID Finder and Legal ID Validator simplify the verification and normalization of company registration numbers worldwide, ensuring your records remain consistent, authentic, and enriched with reliable context.

Each request is assessed through several key dimensions:

• Completeness: Detects missing or incomplete identifiers and, when possible, infers the ID type from the provided country.

• Validity: Confirms that the ID follows the official structure and exists within Delpha's trusted registry for supported countries (see documentation for full coverage).

• Consistency: Compares your input with its normalized version, applying the appropriate format, padding, and length rules.

• Accuracy: Verifies whether the provided ID matches contextual data such as company name or address.

When valid, Delpha returns a normalized and enriched record containing structured details like company name, address, website, and industry. If side fields are provided, the Legal ID Finder can also deliver AI-generated recommendations with confidence scores to help identify the correct registered entity.

With Legal ID Finder and Legal ID Validator, you gain a consolidated, cross-country view of legal identifiers—enhancing data quality, reliability, and compliance at scale.
