In 1994, in an effort to combat piracy, the IFPI and the compact disc manufacturing industry introduced Source Identification (SID) codes, which are markings on CD parts that identify the manufacturers, equipment, and master discs that were used to create each disc.

SID codes are formatted as the letters \"IFPI\" followed by 4 or 5 hexadecimal digits. A SID-marked disc typically bears at least two codes, each imprinted on different physical components. A number prefaced with \"L\" is a \"mastering code,\" a serial number taken from a pool assigned by Philips to the manufacturer. It identifies the Laser Beam Recorder (LBR) signal processor or mold that produced a particular stamper or a glass master disc from which molds are produced. Non-\"L\" numbers are \"mold codes\", the first 2 or 3 digits of which are assigned by Philips to the operator of the manufacturing or mastering plant, which might not be the same plant that manufactured the stamper or glass master; and the remaining digits are a serial number assigned by that plant to its molds.[15][/quote:13gipf1e]
