Division The following principle has been adopted by the Member States:

A ‘national Sirene bureau’ shall be set up by each of the Member States to serve as a single contact point for the other partners, available around the clock.

The legal foundations, the cases when action ought to be taken, the procedures to be followed and the general principles for organising the Sirene bureaux are defined jointly by all Member States so as to have common rules. The arrangements are recorded in this ‘Sirene Manual’.
