what is an eori stands for Economic Operators Registration and Identification number, which is required for businesses involved in customs activities within the European Union. EORI is essential for importing or exporting goods to or from EU countries, serving as a unique identifier in all customs documentation. Without an EORI, shipments may be delayed or rejected at the border. Businesses registering for EORI must provide company details and VAT registration info. Once issued, the number must be used consistently in cross-border trade. It simplifies customs procedures, ensures compliance, and enables smooth international shipping within EU jurisdictions.
