Method for providing parking management and parking location information service and apparatus, and system thereof

A method, an apparatus, and a system for providing parking management and parking location information services are provided to enhance reliability of parking location information by reducing an error in tag recognition. When a vehicle enters a parking lot, a tag recorded with information about the vehicle is generated(S100,S200). A parking location of the vehicle with the tag is determined(S300,S400). Information on the determined parking location is registered in a parking location management server, such that a database is formed(S500). The database is updated when the vehicle is not in the parking lot(S600~S800). The tag is recovered when the vehicle goes out of the parking lot(S900). The registered information on the parking location is supplied through a website communicated with the database.
