Aim. The purpose of this study is to analyze the experience of working with over a hundred communities from various regions of Ukraine to prepare address register data successfully uploaded and verified in the Unified State Address Register (USAR). The first section examines the structure of exchange files for the address register; the second and third sections analyze the data forming the basis for creating the address register; and the fourth section outlines a method for community interaction to refine address register data. Methodology. The methodology for implementing a community address register using GIS technologies is based on collecting, processing, and integrating data from various sources (topographic, master plans, cadastre, OSM, Visicom) to meet USAR requirements. The core involves creating exchange files with geometric and attribute characteristics, transformed into GIS formats using ArcGIS, QGIS, or AutoCAD Map3D. Emphasis is placed on data type correction, preventing attribute loss, and layer standardization. Methods of spatial overlay, standardized coordinate systems (USK-2000), and API automation are applied to ensure data accuracy, integration, and unification. Results. The methodology resulted in the creation of an address register module on a geoportal with integrated editable layers of streets, buildings, and settlement boundaries in feature layer format. Web applications were developed for data management, and communities were provided tools for refinement through web interfaces or software like ArcGIS and QGIS. After data verification, unique identifiers (UUIDs) are assigned to objects, and standardized files are created for uploading to USAR, facilitating the systematization, integration, and use of data for community planning and management. Practical significance. The practical significance lies in creating an efficient tool for community territory management that ensures centralized and accurate address data storage, process automation, and integration with other information systems. This enhances urban planning, property management, administrative services quality, and minimizes errors and data duplication while providing convenient access to information for citizens, businesses, and authorities. GIS technologies enable data visualization on electronic maps, simplifying analysis, decision-making, and monitoring of territorial changes, which is vital for the effective development of communities and their adaptation to modern digital standards.
