associatedentityid

The associatedentityid element is used in XBRL taxonomies to identify an entity associated with the reporting entity in a defined relationship. It is commonly used in disclosures about related parties, associates, joint ventures, and other connected entities as described by the taxonomy.

The value of associatedentityid is a string representing a unique identifier for the associated entity within the filing's scope. Typical forms include a legal entity identifier (LEI), a company registration number, or other jurisdiction-specific identifiers. The exact formats and validation rules are set by the taxonomy and jurisdiction; some filings allow multiple identifiers for different relationship types.

In actual filings, associatedentityid is used with other elements to describe the relationship and enable automated extraction and cross-referencing. Its applicability depends on the taxonomy and regulator; many taxonomies do not require this element. Consult the governing taxonomy documentation for how to implement and validate values.
