Documents submitted to municipalities can amount to a lot of paperwork, whether it is an application for benefits, a scholarship or for public day care centers.
But starting Monday, there may be less paperwork for those who use the My Number identification system as residents' data is now being shared between central and local governments, administrative bodies and other institutions such as Hello Work, the nationwide public employment service.
Officials say this will reduce the need for the pile of documents that until now has often been necessary.
