Rear label
Provided by the ASK Keyboard Dictionary
Aka/also known as: birth certificate
A keyboard's rear label is a sticker typically placed on the bottom of a keyboard that details some basic facts about the keyboard. Typical fields on such a label can include the keyboard's part and/or model number, FRU number, date of manufacture, country of manufacture, OEM and/or factory, copyright date and any applicable regulatory information. The typical inclusion of a manufacture date has led to these stickers colloquially being referred to as the keyboard's "birth certificate". Additionally, keyboards may have multiple such rear labels - typical for IBM and Lexmark era Model F and Model M keyboards is having an "outer rear label" on the bottom of the cover set and an "inner rear label" on the bottom of the contained keyboard assembly.
