Those codes, in circles, that all food has...

[Siamsal]

Does anyone know the official name for the codes, in an oval, that all food produced in the EU is supposed to have on it? Usually something like UK | CF478A | EEC. I know it is suppsed to identify the producer, precisely.

Or, even better, anyone have a reference to the lists of producers, so I can look one up?

It is called the approval number or health mark.
