EORI, Economic Operators Registration and Identification, is one of the elements of the European electronic customs system. All traders wishing to act before the European customs authorities are subject to a one-time registration in the system and obtain a unique EORI number, which is used to identify them before customs authorities throughout the Union European. In Poland the registration process is carried out in The Integrated Commodity Trading Entrepreneurs’ Registration System (SZPROT), and applications are submitted via Electronic Services Portal of the Customs Service (PUESC).
