Identification for EU citizens

eIDAS identification is not yet in use in the Import Declaration Service for private persons, Export Declaration Service, Contact Customs Information or Attachment Upload Service. There are, however, the following alternatives:

  • Authorise another person to declare the goods on your behalf in our Import Declaration Service for private persons.
  • Call the Customs Information Service to ask for advice.
  • Authorise an agent, e.g. a forwarding company or Posti, to declare the goods on your behalf.
  • Submit an export declaration without identification in our Export Declaration Service
  • Send attachments to Customs by email.
  • Visit a customs office. Contact information and opening hours

Why should you be identified when using our services?

When you are identified, you can usually handle your customs transactions without having to visit a customs office. You can also use declarations you have submitted earlier as templates for new declarations and browse them in the service to a limited extent for a specific period of time. However, when using the online Transit Declaration Service, you must always visit a customs office when starting the transit procedure.
