PRESS RELEASE: CTU has prepared a self-identification calculator for digital services 17.9.2025 Tereza Meravá | Český telekomunikační úřad Prague, 17 September 2025 - CTU, as the future Digital Services Coordinator, has prepared a guide for undertakings that are unsure about their obligations under the European DSA and P2B regulations. The calculator works on the principle of self-identification. Interested parties first indicate what activities they perform and then state the size of their undertaking. The self-identification calculator then provides an indicative assessment of which category of service providers the undertaking falls into and what specific obligations are associated with this. The self-identification calculator is available free of charge on the CTU website (available in Czech only). It is simple and safe to use. The data entered is not stored or further processed in any way. If any undertaking is interested in a more detailed consultation, we recommend contacting CTU by email at podatelna@ctu.gov.cz. http://ctu.gov.cz/node/537223
