The term "Non-EEA" refers to countries that are not part of the European Economic Area (EEA). The EEA includes EU member states as well as Iceland, Liechtenstein, and Norway. In the payment sector, non-EEA transactions often involve higher fees, stricter regulatory requirements, and additional security checks. Merchants and payment service providers must pay special attention to compliance requirements, such as anti-money laundering regulations and fraud prevention, when processing payments from or to non-EEA countries.
