        abstract = {Rapid urbanisation demands a shift from voice-based helplines to data-driven, location-aware emergency systems. This paper presents a GPS-integrated, multi-zone Emergency Alert and Dispatch System built on the MERN stack (MongoDB, Express.js, React.js, Node.js). The platform supports citizens, responders, and administrators across Police, Ambulance, Fire Brigade, and Child Helpline services within defined geographic zones. The Haversine formula enforces coverage validation, rejecting out-of-zone alerts with hotline guidance. Socket.IO enables sub-second, real-time communication for alerts and GPS tracking. Leaflet.js provides live geospatial visualisation. Security uses JWT-based access control and bcrypt hashing. Evaluation shows latency below 100 ms and accuracy above 96%, confirming system reliability and scalability},
