EPP is a stateful XML protocol that can be layered over multiple transport protocols. Protected using lower-layer security protocols, clients exchange identification, authentication, and option information, and then engage in a series of client-initiated command-response exchanges. All EPP commands are atomic (there is no partial success or partial failure) and designed so that they can be made idempotent (executing a command more than once has the same net effect on system state as successfully executing the command once).

EPP provides four basic service elements: service discovery, commands, responses, and an extension framework that supports definition of managed objects and the relationship of protocol requests and responses to those objects.

An EPP server MUST respond to client-initiated communication (which can be either a lower-layer connection request or an EPP service discovery message) by returning a greeting to a client. A server MUST promptly respond to each EPP command with a coordinated response that describes the results of processing the command.
