If you are calling from a landline, you will usually immediately be transferred to an emergency medical dispatcher in the region in which you are calling from. If you call on a mobile phone, the police emergency dispatch centre in Driebergen will receive your call. The emergency dispatcher will immediately ask for your location and which emergency service you require (police, fire or ambulance). You will then be quickly transferred to the correct emergency dispatch centre. In all cases (even if caller ID is blocked), your telephone number is visible to the dispatcher. Your location is not automatically visible if you call using your mobile phone.
