Z classification system

From Halopedia, the Halo wiki

The Z- or Zeta-classifications are a system of classification employed by the United Nations Space Command for cataloguing Forerunner technology and materiel.[1] The system serves as a counterpart to the UNSC's type classification system used for cataloguing Covenant technology.


The cataloguing system used by UNSC analysts for Forerunner technology sees a given item designated with a Z-, followed by a numerical string. Known strings range from low double digits to quadruple digits, with no apparent indication the numbers employed have any particular inherent meaning (unlike, for example, the Type-designation system's correspondence with the year of cataloguing). Z-classifications are given to a wide array of technology ranging from infantry weapons to Sentinels to even spacecraft.
