As from 1st April 2012, Regulations 883/2004 and 987/2009 will apply in the relation between the EU Member States and Switzerland. They will replace the currently applicable Regulations 1408/71 and 574/72. However, transitional provisions will be foreseen, like this was the case when the new Regulations became applicable for the EU Member States.

For the time being, Regulations 1408/71 and 574/72 will however remain applicable in the relations with the EFTA Member States (Iceland, Liechtenstein and Norway).
