The Moscow Basic Register is the city's system of electronic interagency interaction providing public services to residents. The creation of the basic register allowed Moscow to convert many public services, in which several government agencies and organizations are involved, to the online format.

In November 2021, interagency cooperation made it possible to convert the registration or renewal of the status of a multi-child family to the online format and to stop using paper certificates confirming this status to receive support and benefits.

The Moscow Basic Register allows the specialists of government agencies responsible for the provision of services receive the necessary documents during electronic interagency interaction.

Among the first documents that the city’s authorities began to receive as part of interdepartmental interaction are the documents with information about city benefits and support measures, extracts from the Unified State Register of Sole Entrepreneurs and the Unified State Register of Legal Entities, checking the validity of a passport, Rosreestr extracts and housing records.
