Ring codes are more useful than the SLUS/SLES etc. numbers actually. Some games have the exact same PlayStation ID number between versions while the matrix is completely different due to being a different pressing. The SID codes and toolstamps are fairly unimportant however as these change during the manufacturing process.
@ F1ReB4LL: I am not sure if there is a public list of every single disc made by Sony. The Sony DADC part numbers are on most "PAL region" Sony-made discs regardless of what optical media it is e.g. games, data, audio, movie DVDs, UMDs, Blu-Ray, they are simply done sequentially on what happens to be the next disc to be stamped, with no preference to what format the disc is. Note that some European/Australian Sony discs were instead stamped with the "NTSC" style IDs instead, these are not part of the same list. DADC discs made before circa 1994 are also in a different numbering format and these don't count either. I do not know what the A00/A01 at the start signifies (older DVDs and PS1 launch titles like Tekken 1 don't have the A01 but most other PS1 games do) but it isn't part of the serial number.
