What do these codes on my CDs mean?

On some of my CDs' jewel cases there are short, three- or four-character codes directly after the catalog number on the spine or the back of the case. The codes do not show up on the CDs themselves. The codes are printed in square boxes, similar to old-school track numbering and digital/analog recording identifiers (DDD, ADD, AAD).
I have only found them on records published by Decca (London, Argo, etc.), Deutsche Grammophon (and Archiv), and Philips. The only consistent trend between these is that they all have some connection with Polygram or Polydor.
Examples from DG:
445 542-2 [G][MA]
289 463 612-2 [G][OR]
439 006-2 [G][HS]
Example from Philips (this only appears on the back of the case):
420 354-2 [P][M]
Examples from London and Argo, respectively:
410 017-2  [L][H]
414 595-2 [Z][H]
