Authorisation Service

Companies and corporations

You can apply for customs authorisations by using our Authorisation Service. At the moment, you can apply for authorisations for comprehensive guarantees and payment deferment. Later, the service will be extended, allowing you to also apply for other authorisations electronically.

In the service, you can also

  • browse authorisation decisions
  • submit attachments to your authorisation application
  • save the application as a draft and select a previous application as a template for a new one
  • view and print out authorisation decisions.

Read our guidance before applying for an authorisation

Before applying for the authorisation, make sure that your company has the necessary details, including an EORI number.

Make sure that you have the attachments, documents and other information (e.g. financial statements and guarantee details) that are required to apply for the authorisation.

In the Authorisation Service, you can find guidance on how to fill in the authorisation application. You can also get help with your application via phone, email or chat.
