The application provides a method for obtaining an equipment identity (ID), a terminal and network equipment. The method includes the following steps that: the terminal sends a first message for acquiring an equipment ID to the network equipment, wherein the equipment ID is used to globally and uniquely identify the terminal; the terminal receives an encrypted key pair sent by the network equipment, wherein the key pair includes a first public key and a first private key; the terminal receives information sent by the network equipment, wherein the information is used to identify the first public key as the equipment ID of the terminal; and the terminal determines that the first public key is the equipment ID. According to the method, the duplication of the equipment ID can be effectively avoided, the configuration process can be simplified, the system overhead can be saved, and the security and availability of an overall scheme for obtaining the equipment ID can be improved.
