Realising the difficulties citizens face in dealing with different departments of the State and Greater Hyderabad Municipal Corporation (GHMC), the civic body proposed to have a unique digital number to each property within the GHMC limits. A pilot project Property Aadhaar-Digital Door Numbering (DDN) was started in Moosapet circle by GHMC additional commissioners Musharraf Faruqui and Adwait Singh. It is learnt that soon properties will be identified only with a single DDN for all purposes. A geo-tagging based seven digit code has been finalised.
