SIRENE stands for Supplementary Information Request at the National Entries.

Each EU country operating SIS has set up a national SIRENE Bureau, operational 24 hours a day, seven days a week, that is responsible for any supplementary information exchange and coordination of activities connected to SIS alerts.

Efficient SIRENE cooperation is a key element for the effective functioning of the concept of SIS. The cooperation between EU countries may be one-to-one or one-to-many and always needs to be linked to a specific SIS alert. In order to ensure prompt, confidential and efficient follow-up of cases, communication is accomplished through the structured exchange of standardised forms via a secure network.

The tasks of the national SIRENE Bureaux include, among others:

  • providing supplementary information on alerts
  • validating alerts on persons wanted for arrest
  • contacting the Member State that issued the alert when a match (hit) has been made and the required action has been taken
  • contacting the Member State that issued the alert when the required action cannot be taken
  • supervising data quality and compatibility of alerts
  • coordinating cross-border activities related to SIS alerts
  • handling requests to access personal data

A SIRENE Manual has been published containing detailed rules and procedures on SIRENE cooperation and other implementing rules for SIS.

The list of national SIRENE Bureaux is published in the Official Journal of the European Union.
