A CDKID (CanuckDUCK Identifier) is a unique identification code assigned to entities within the CanuckDUCK platform. The standardized format allows easy identification of entity type and jurisdiction. CDKIDs begin with 'CDK' followed by a province code (like AB for Alberta or CA for federal), an entity type code (MUN for municipality, NPO for non-profit, BUS for business, EDU for education, GOV for government), and a unique 20-character string. For example, a Calgary municipality identifier might be CDK-AB-MUN followed by unique characters. This systematic approach enables the platform to organize and link information across different types of organizations and government levels throughout Canada.
