Please note: PolyGram 7 numeral catalogue numbers were introduced in April 1970 - any earlier release with such a number is a reissue after that date.
This catalogue numbering system was replaced a with a new system, initiated in August 1982, which was tied to the barcode/EAN. It had six digits followed by a single number suffix denoting the format, usually xxxxxx-x. In the US this was often prefixed by a 3 digit code denoting a company division, so xxx xxxxxx-x, and sometimes a further 1 letter suffix (for example 422 822104-1Y). These new numbers were not seen until early 1983 when compact discs were first released to the public outside Japan.
Words such as Deluxe, Super, Special and Select are not part of the catalogue number - these are price codes and can be entered as identifiers.
For all unofficial releases (bootlegs, counterfeits, pirate compilations ...) that pretend to be Polydor releases, please use Polydor (2).
