Disclosed are a code-based device access method and a user device for a code-based device access. A PN code is generated by combining a general subscription phone number and/or a particular number on the basis of a conventional phone number system with a special number existing in a dial pad. An exemplary system for the code-based device access method and the user device for the code-based device access may include a PN code server including a communication server, a registration server, or a notification server, a network, a mobile device, and a site server. The mobile device may include an application which provides a PN code service, and the application may include a module which can communicate with the PN code server, another mobile device and/or the site server through the network. |
