Division 2.1.2 Checking for multiple alerts on a person

To avoid entering incompatible multiple alerts, care must be taken to distinguish accurately between individuals who have similar characteristics. Consultation and cooperation between the Sirene bureaux is therefore essential, and each Member State shall establish appropriate technical procedures to detect such cases before an entry is made.

The elements used for establishing whether two identities may be identical are detailed in Annex 6 of this manual.

The following procedure has been adopted:

1. (a)

   if processing a request for entering a new alert reveals that there is already a person in the SIS with the same mandatory identity description elements (surname, given name, date of birth) a check must be run before the new alert is approved;

2. (b)

   the Sirene bureau shall contact the national issuing Sirene bureau to clarify whether the alert relates to the same person (L form); and

3. (c)

   if the check reveals that the details are identical and could relate to the same person, the Sirene bureau shall apply the procedure for entering multiple alerts. If the outcome of the check is that the details relate to two different people, the Sirene bureau shall approve the request for entering the new alert.
