The Office of Departure initiates operations such as:
 Check guarantee integrity ;
 Register guarantee usage;

2.2.3.5 NCTS Central Services
Central Services are defined at two different levels: National Domain and Common Domain
whose needs are different. At the level of National Domain, they contain the functions that are
common to different types of Customs Offices and the functions to manage the national
information of reference (such as Customs Offices). For the Common Domain, they contain the
functions to manage the information that is common to all countries (such as country codes).
The Central Services are implemented through CS/RD (Central Services/Reference Data)
system.
