Overview#

Data Country Codes (DCC) are the ITU-T Country Codes which as far as we can tell is the same as the ISO 3166-1 alpha-2

According to Rec. ITU-T X.660 | ISO/IEC 9834-1, clause A.2.5, subsequent arcs have the values of Data Country Codes (DCC) as defined in Rec. ITU-T X.121. Arcs below this are determined as necessary by the Administration of the country identified by the DCC.

Each country should be assigned at least one 3-digit DCC. The DCC in conjunction with the fourth digit (of the OID) can identify up to 10 public data networks.

Data Country Codes are followed by Network Digits to create Data Network Identification Codes (DNIC). DNICs are registered under {itu-t(0) network-operator(3)}.

See the list of Data Country or Geographical Area Codes (sub-arcs in this OID repository are in accordance with the list of DCC codes issued on 15 Mar 2011).
