Abstract: An entity validation platform maintains a database of unique identifiers for entities participating in one or more supply chains. Each unique identifier can be used to validate an identity of a respective entity participating in the one or more supply chains. A request is received by the platform for assignment of a unique identifier for a supply chain entity. The request can include an indication of a name associated with the supply chain entity and an indication of products and/or services associated with the supply chain entity. The platform can validate an entity ownership structure associated with the supply chain entity and/or a geographic location at which the supply chain entity is operating. In response to validating the entity ownership structure and the geographic location for the supply chain entity, the platform can update the database to assign the unique identifier to the supply chain entity.
