The present invention relates to an LBS system in which user location information is obtained using a ULID code of RFID tags attached to various places such as a building, a store, road signs, footway and road, and various LBSs are provided based on the location information. The problems that can be caused when using a conventional GPS and a wireless network are solved. It is easy to immediately obtain location information through a tag and security of private information can be enhanced. The LBS system of the present invention of the present invention includes: a plurality of RFID tags distributed on various places, for wirelessly providing a ULID code of a location; an RFID reader for wirelessly receiving the ULID code from an adjacent RFID tag; a local ULID processor for extracting current location information through a wirelessly received ULID code; and a local LBS application for providing a user with an LBS on the basis of the extracted location information.
