How is the place of residence of an IDP checked?

In two days, a person is warned about the verification by phone or by sending a message, for example, on Viber. If a person reported his absence due to staying with relatives or, for example, vacation, the check is postponed for two weeks. If the person will not be at the place of residence after 2 weeks, they will draw up an act and leave an official notice of the need to come to the social security body at the place of residence for identification within 14 working days.
