This initialization, often called process creation, ensures that the new process starts its life in a well-known situation and that the system will actually be able to keep track of it during its entire lifetime. At the same time, most operating systems also give to each process a process identifier (PID), which is guaranteed to be unique for the whole lifetime of the process in a given system and must be used whenever it is necessary to make a reference to the process.

In Erlang/OTP, each process has a process identifier (pid) which serves as a unique identifier for message transmission. Erlang/OTP also features mechanisms for both local and global name registration: local names have scope within each node, whereas global names have scope within the global group. Registered names and process identifiers can be used interchangeably, since registered names are automatically resolved when a message is sent.
