Hello! I actually don't recall if they ever explicit used the phrase 'BC-303' or 'BC-304' in the series. These are the sources I know off the top of my head:
 * 1) In the episode Enemy Mine (right near the start of the episode), colonel Martin Edwards references to the Prometheus as a 'Battle Cruiser'.
 * 2) A knock-off lego set (officially licensed by MGM) reffers to the Daedalus-class as a BC-304.

The prefix 'X-302' or 'X-303' refers to the fact that is was an 'experimental' craft. The Daedalus was referred to as the 'X-304' in Moebius, Part 1 (as it was the first of its class), but no other 304 was referred to as an 'X-304'.
