Under this arc, a range of labels can be allocated to international
organizations recognized by ISO.
ISO/IEC 6523-1 specifies a structure for globally and
unambiguously identifying organizations, and parts thereof, for the
purpose of information interchange.
Information:
Every one has an international code or ICD with 4 digits. The ICD values are all integers from 1 to 9999. An ICD value is allocated to an organization identification scheme in accordance with the procedure specified in ISO/IEC 6523-2. ICD values shall be assigned sequentially in the order in which entries are added to the register. To guarantee unique identification of organization identification schemes, an ICD value once assigned shall not be reallocated. When an organization identification schema ceases to be supported, the registration entry shall be marked as such, but the entry itself shall be kept in the register, and the ICD value shall not be reallocated.
Interchanging partners may want, by prior agreement, to interchange organization identifiers allocated by an identification scheme to which an ICD value has been assigned, or for which the assignment of an ICD value is pending. The range of ICD values between 9900 and 9999 is reserved for that effect. The interchange partners shall agree on the identification of the identification scheme, using one of the above reserved values.
