EORI number – an important identifier in customs transactions

Importers and exporters who trade with countries outside the EU need an intra-EU business identifier – an EORI number – for almost all customs declarations. You can use this identifier in your transactions an authorisation to use one identifier in their transactions with the customs authorities of any EU Member State. Transport companies must also have an EORI number.

A Finnish private individual needs an EORI number for reporting goods subject to the carbon border adjustment mechanism (CBAM goods) to the EU Commission. Apply for an EORI number from Customs. Companies established in another EU country must apply for an EORI number from the competent authority in that country.
