P+O is a CD manufacturer located in Diepholz, Lower Saxony, Germany. The "-Pallas" addition appears on numerous CDs and indicates that P+O is part of the Pallas Group. Sometimes it is also mentioned as "P+O, Diepholz". In the matrix of CDs only the reference "P+O" is used.
The company was established in October 1986 as P+O Compact Disc GmbH. In November 2005 the company was restructured into P+O Compact Disc GmbH & Co. KG
On April 1st 2013 the manufacturing plant burnt down, resulting in damage of about €10m.
A new manufacturing plant started production in 2014, although P+O appears to have transitioned to acting solely as a broker since as early as 2019.
The identifying markings on the ring are generally (if not ordered otherwise by the customer) made up as follows:
P+O: Manufacturer
A: CD-Audio (or R = CD-ROM, or D = DVD)
XXXXX: Five or six digit 'working number' of the title
A1: Master version (A) cq. stamper (1)
Numbering scheme up to year 2007:
P+O-XXXXX-A1
where XXXXX is a four or five digit number.
Also used is P+O-XXXXX-A1 mm/yy, with mm/yy being the month/year of production. Do not add as Release Date.
Master version, stamper, month and year are NOT to be added as the production number (as per discussion).
Different versions of master and stamper are to be added as manufacturing variants in the BAOI section.
