Division 2.12.3 Use and distribution of Interpol diffusions and notices in Schengen states

Given the priority of SIS over Interpol alerts, Interpol alerts shall be restricted to exceptional cases (i.e. where there is no provision, either in the Convention or in technical terms, to enter the alert in the SIS, or where insufficient information is available to enter an alert into the SIS). Parallel alerts in the SIS and via Interpol within the Schengen area are inadmissible. alerts which are distributed via Interpol channels and which also cover the Schengen area or parts thereof (Interpol diffusion zone 2) should bear the following indication: ‘Zone 2 except for the Schengen States’.
