Consignments containing documents should be indicated by checking the ‘Documents’ box in the ‘Category of item’ section of the form.

Ideally, submit all address, contact, and customs clearance data for your consignments online, e.g. using the application Send Consignment. This will give you access to many benefits including:

  • Postage reduced by of up to CZK 8 for letters;
  • Completion of the CN 22/CN 23 customs declaration form for consignments destined to countries that require such a form;
  • Sending a certificate of posting to your email address;
  • Faster posting at a post office by using a generated code;
  • Use of implemented automatic word completion boxes and checking mechanisms;
  • Absence of errors due to the copying of data from paper forms;
  • Correct and complete posting data guarantee a shorter overall duration of transportation and problem-free customs clearance and delivery.
