Hull Registry Code

The Core Systems Free Republic requires all jumpworthy vessels, foreign- or domestic-owned, to have a hull code registered to the vessel, its name and its owner of record. Not all nations or individuals observe this requirement seriously, but the vast majority of ships plying the stars of the Republic are marked externally with a 9-10 character code, and have a formal record of same registered to their owner of record. A sample of a hull registry code would be that of the CSRS Imhotep, CSNDH1827:

Nation of Origin Owner Type Ship Class Department or Group Unique 4-Digit Identifier
CS N D H 1827

Nation of Origin

The first two characters refer to the ship's nation of origin:

The third character denotes the nature of the vessel's owner:

  • C - Corporate

  • M - Merchant Marine Service
  • N - Naval
  • P - Private Individual
  • Q - Unconventional/Unknown - usually applied in the case of salvaged ships of unknown provenance
  • S - Scout Service

The fourth character signifies what class (or general purpose) the vessel is assigned:

  • A - Superheavy - esp. 300,000+ dtons
