The paper is proposed to provide users of mobile devices personalized services tailored to their current location. The main research in the paper concerns with the spatial query processing and mobile location based service delivery. The paper relays on geocoding service which performs as a geocoder by determining a geographic position, such as a place name, street address or postal code. The geocoding process is done by giving geographic positions with geographic co-ordinates latitude and longitude, other points and features where the features can be mapped and entered into Geographic Information Systems. The validity region of a query is returned to the user along with the query result in which validity region indicates the geographic area within which the result of the query remains valid. Spatial data occupies a spatial extent, which stores location and boundary in the spatial database.
