***

### Answer

\[ESMA 70-1861941480-56 MiFIR data reporting Q&A, Q&A 24.2\]

The table below shows the list of national client identifiers for natural persons to be used in transaction reports pursuant to the priority specified in Annex II of the Commission Delegated Regulation (EU) 2017/590. Information related to the format of the identifier is not provided in the case of CONCAT, since the procedure for generating such identifier is defined in Articles 6(1) and 6(4) of the Commission Delegated Regulation (EU) 2017/590.
