The present invention relates to a mobile terminal and a method for preventing illegitimate change of an identification number of the mobile terminal. The method includes receiving, if change of an identification number is requested, and storing new authentication information and encoding the authentication information; determining whether a previously stored first authentication information exists; storing, if a previously stored first authentication information does not exist, an identification number, and storing the encoded authentication information as a first authentication information; and determining, if a previously stored first authentication information exists, whether the encoded authentication information corresponds to the first authentication information, and storing an identification number, if the encoded authentication information corresponds to the first authentication information, and performing error handling, if the encoded authentication information does not correspond to the first authentication information. |
