SeaBox is one of the services we provide at LetterBox. Our customers are non resident but are boatowners  that sails under the Croatian flag. Our customers can also be persons who have a residency  in Croatia, but the law does not oblige them to do so.

Here are 5 benefits why you should use our service SeaBox:

  1. We guide you through the entire appointment process.
  2. We can make all the appointments online, so there is no need for you to come to us. However  – we are always glad to have you in our office in Rijeka or Zagreb.
  3. You can also appoint us as a rappresentative, but only in the form of communication with public law bodies – for all professional representation, you appoint them depending on your needs.
  4. LetterBox is registered for the service of receiving mail for a third party. This is our main activity that we provide – however we cooperate with different professionals and partners
  5. With us you will get a local guy who can always assist you with your boat in Croatia.
