ISOFIX is a standardized anchorage system based on ECE Regulations 14, 16 and 44 and serves to secure the child seat in the car correctly for as long as required. When ISOFIX is used, installation errors that would otherwise occur are avoided, and the handling of the child seat becomes much easier.

The UDV has compiled two lists showing which vehicle types have ISOFIX attachment points and which ISOFIX child seats are available for them: the car list and the child seat list. The ISOFIX lists allow families to get the latest information when buying a new or used car or a new child seat.
