Where the CIR or SIS are queried and where a white link exists between data in two or more of the EU information systems, the MID shall indicate that the identity data of the linked data correspond to the same person. The queried EU information systems shall reply indicating, where relevant, all the linked data on the person, thereby triggering a match against the data that are linked by the white link, if the authority launching the query has access to the linked data under Union or national law.

Where a white link is created between data in the EES, VIS, ETIAS, Eurodac or ECRIS-TCN, the individual file stored in the CIR shall be updated in accordance with Article 19(2).

Without prejudice to the provisions related to the handling of alerts in SIS contained in Regulations (EU) 2018/1860, (EU) 2018/1861 and (EU) 2018/1862, and without prejudice to limitations necessary to protect security and public order, prevent crime and guarantee that no national investigation will be jeopardised, where a white link is created following a manual verification of different identities, the authority responsible for the manual verification of different identities shall inform the person concerned of the presence of similar or different identity data and shall provide the person with the single identification number referred to in Article 34(c) of this Regulation, a reference to the authority responsible for the manual verification of different identities referred to in Article 34(d) of this Regulation and the website address of the web portal established in accordance with Article 49 of this Regulation.

If a Member State authority has evidence to suggest that a white link has been incorrectly recorded in the MID, that a white link is out of date or that data were processed in the MID or the EU information systems in breach of this Regulation, it shall check the relevant data stored in the CIR and SIS and shall, if necessary, rectify or erase the link from the MID without delay. That Member State authority shall inform the Member State responsible for the manual verification of different identities without delay.

The information referred to in paragraph 4 shall be in writing by means of a standard form by the authority responsible for the manual verification of different identities. The Commission shall determine the content and presentation of that form by means of implementing acts. Those implementing acts shall be adopted in accordance with the examination procedure referred to in Article 74(2).
