OID description

  "country" is a standardized identifier (this identifier may be used without its associated number in the ASN.1 notation of an OID).
OID: (ASN.1 notation)
(dot notation)
(OID-IRI notation)


Joint (ITU-T and ISO/IEC) registration within a country


According to ITU-T X.660 | ISO/IEC 9834-1, clause A.5.5, "The primary integer values (and hence the integer-valued Unicode labels) assigned to arcs under this object identifier are the values of the numeric-3 codes of ISO 3166-1 [for a United Nations (UN) Member State], and non-integer Unicode labels and secondary identifiers are assigned that are the (two-letter) alpha-2 code elements of ISO 3166-1 [capitals for the Unicode labels, lowercase letters for the secondary identifier; see the correspondence table between country codes and OIDs]. ISO 3166-3 identifies historical numeric-3 codes that can still appear in old OIDs.
The nodes identified by these arcs may be used to assign subordinate arcs within a country. The administration of nodes identified by these arcs is not prescribed by Rec. ITU-T X.662 | ISO/IEC 9834-3, but it is recommended that a single national Registration Authority be determined by the joint decision of the country's ITU Member State and the ISO National Body (and, if necessary, the IEC National Committee for the country). The assignment of registration responsibilities within a country is a national decision."

This national decision does not need to be ratified by a formal joint Resolution of ITU-T SG 17 and ISO/IEC JTC 1/SC 6 which are the subgroups responsible of Rec. ITU-T X.660 | ISO/IEC 9834-1. However, once a Registration Authority (RA) has been designated for a country OID, it is recommended that a letter be sent to inform both ITU-T SG 17 and ISO/IEC JTC 1/SC 6, so that they can update the register of the superior OID, namely {joint-iso-itu-t(2) country(16)} (see example of such a letter).

More information can be found at Operation of a country Registration Authority.
