	DVD-5 with Mastering SID LV26 will often have a second mastering code printed below the main one ([https://web.archive.org/web/20260313073938/https://cdn.discordapp.com/attachments/418896419986997249/1481319458147668169/image.jpg?ex=69b4dc00&is=69b38a80&hm=529f8c71341348fea65db69b700da032eb6f5cc98aab25d6051653abd4fbe2a8& Example]).

DVD-5 with Mastering SID LV26 will often have a second mastering code printed below the main one ([https://web.archive.org/web/20260313073938/https://cdn.discordapp.com/attachments/418896419986997249/1481319458147668169/image.jpg?ex=69b4dc00&is=69b38a80&hm=529f8c71341348fea65db69b700da032eb6f5cc98aab25d6051653abd4fbe2a8& Example]). Add these to the L1 field of Redump.

		+	===Cinram===
		+
		+	Cinram mastered discs (IFPI L381 - IFPI L390, most commonly seen on L386 ones) will often have mastering SID's printed as part of the mastering code without IFPI ([https://web.archive.org/web/20260329114458/https://cdn.discordapp.com/attachments/418896419986997249/1487779436215406674/20260329_064205.jpg?ex=69ca6213&is=69c91093&hm=82db3f73accd8fbb56c37998475f519aa7cd738e3f23595af6a21515eea356af& Example]). This is still treated as a Mastering SID for Redump purposes though, so add it to said field and replace it with a TAB character in the mastering code.
		+
		+	In addition: The mould SID (Most commonly IFPI 6000) is often printed without gaps on discs by this company. Add this to the relevant field as is

		+
		+	==Company-Specific Quirks==
		+	===MPO===
		+
		+	Discs mastered by MPO (IFPI L031 - IFPI L040) will often have time and date printed as an appendix to the Mastering SID ([https://web.archive.org/web/20250709101721/https://media.discordapp.net/attachments/418896419986997249/1282627316773556306/IMG_20240806_0001.png?ex=686f81c6&is=686e3046&hm=08c632161444826d57956d48f284db52ebc8596dd46ce604e61ec253e7735e1b&=&format=webp&quality=lossless example]).
		+
		+	Redump does not consider these as part of the Mastering SID though and they should instead be appended to the Mastering Code with a <tab> character.
		+
		+	===Disctronics and Nimbus===
		+
		+	Disctronics and Nimbus (IFPI L121 - IFPI L130 and IFPI L501 - IFPI L510) mastered discs will sometimes have their Mastering Codes printed in such a way that they become mirrored on the data side ([https://web.archive.org/web/20250709103326/https://media.discordapp.net/attachments/442166152454733826/1285881528311742496/IMG_20240918_0001.png?ex=686f7afe&is=686e297e&hm=d79ef4abc47232c775909ad82c83c7ef976ec981373811dec763f50d16eee8a5&=&format=webp&quality=lossless example)] and visibly when viewed from the label side.
		+
		+	Despite often looking like they are printed on the label side the codes are in fact not. And only the Data side Mastering Code field should be filled when submitting to Redump.
		+
		+	Nimbus mastered discs additionally has what Redump refers to as "Nimbus Dots". For more info on these and how to add them see the page for [http://wiki.redump.org/index.php?title=Symbols,_Logos,_and_other_Special_Cases "Symbols, Logos, and other Special Cases"].
		+
		+	===Sonopress and Arvato===
		+
		+	Mastering SID's by these companies (most notable in the LBxx and LPxx range) can be printed either with the standard "Lxxx" format or as "Lx xx" with a gap in the middle ([https://web.archive.org/web/20250710093835/https://i.ibb.co/hF1LhXTF/P-20250710-111815.jpg IFPI LP 73 example]). The reason for this disparity is unknown and both can sometimes be found on Dual Layer discs ([http://redump.org/disc/71833/ example])
		+
		+	When submitting to Redump these get added as is.
		+
		+	===Advant Medien===
		+
		+	DVD-5 with Mastering SID LV26 will often have a second mastering code printed below the main one ([https://web.archive.org/web/20260313073938/https://cdn.discordapp.com/attachments/418896419986997249/1481319458147668169/image.jpg?ex=69b4dc00&is=69b38a80&hm=529f8c71341348fea65db69b700da032eb6f5cc98aab25d6051653abd4fbe2a8& Example]). Add these to the L1 field of Redump.
