If you are referring to the part number of the ECU, it will be on the ECU itself.

Thanks. I'm not too sure. Is there such a thing as program code?

One of the functions of the ECU is to store "trouble codes" which identify malfunctions in the system, one of which could have led to the diagnosis of an ECU failure to start with. I don't know how you got to the point of condemning the ECU, but it's not something that is easily determined.
