Recital 4

(4)To ensure unique, consistent and robust identification of natural persons referred to in order records, those should be identified by a concatenation of the country of their nationality followed by identifiers assigned by the country of nationality of those persons. Where those identifiers are not available, natural persons should be identified by identifiers created from a concatenation of their date of birth and name. The identification of natural persons should be conducted following the level of prioritisation of different identifiers detailed in Annex II of Commission Delegated Regulation (EU) 2017/590 ² .
