There isn't a single specific code; a code group is suitable for meeting the requirements. For the IV (Individual Activity) code group, we recommend:
63 (Informacinių paslaugų veikla) for DA, DS and DE;
62 (Kompiuterių programavimo, konsultacinė ir susijusi veikla) for WD.
73 (Reklama ir rinkos tyrimas) for DM & Analytics.
However, we always suggest consulting with your UZT consultant to ensure that the requirements are met.
