The EORI (Economic Operators Registration and Identification) number is a unique identifier assigned to businesses engaged in international trade. It is required for customs clearance both when importing and exporting goods outside the European Union, such as from China or to the United Kingdom. In Poland, the EORI number is issued by the National Revenue Administration (KAS). Applications can be submitted online via the PUESC (Electronic Tax and Customs Services Platform). Obtaining an EORI number is free of charge and typically takes between one and three working days.
