### Question

By when do ISINs have to be obtained for financial instruments submission of reference data for which is triggered by an order, quote or trade taking place?

***

### Answer

\[ESMA 70-1861941480-56 MiFIR data reporting Q&A, Q&A 4.2\]

For financial instruments for which submission of reference data is triggered by an order, quote or trade taking place, the ISINs have to be allocated in time to be included in the submission of reference data required under Article 2 of RTS 23\[1\].

\[1\] Please note that, for ease of reference, RTS have been numbered in this document in accordance with the numbering used in the package sent by ESMA to the Commission in September 2015 (ESMA/2015/1464). Readers are nevertheless invited to consult the Commission and European Parliament websites for updated versions of those RTS.
