The CEAS is binding on all EU Member States except Denmark and Ireland. Ireland is not bound by any instrument adopted pursuant to the treaties in the field of asylum but can opt in to any such instrument. Ireland opted into the recast Reception Conditions Directive in 2018. Denmark has consistently opted out of treaty provisions in the field of Justice and Home Affairs, including issues concerning asylum (TFEU, Article 78). Consequently, Denmark does not participate and is not bound by the treaty provisions or any secondary legislation relating to CEAS, with the exception of the Dublin and Eurodac Regulations, which Denmark applies pursuant to an international agreement. Iceland, Norway and Switzerland are not bound by EU directives; however, similar national provisions apply. Given that these countries are bound by the Dublin III Regulation, additional provisions may apply. References to countries not bound by CEAS should be read in conjunction to existing legal frameworks.
 EU+ countries include EU Member States, Iceland, Norway and Switzerland.
 Each Länder is responsible for defining their own operating standards and reception conditions. For the purpose of the overview and data visualisation of the reception authorities, if some of the Länders in Germany provide a service, it was counted as a service offered in Germany and marked with ‘yes.’
