At the end of 343 Guilty Spark the Monitor says: "Greetings, I am the monitor of installation zero four, I am Three Four Three Guilty Spark. Someone has released the Flood. My function is to prevent it from leaving this installation, But I require your help, come, this way."
So as you can see his name is 343 Guilty Spark, because he says it himself.
