OID Repository
View at oid-base.comNote: The existence of a country code in ISO 3166 does not necessarily imply that there is an ISO Member Body for that country, or that the ISO Member Body for that country administers the country OID arc.
When a country wants to use allocate OIDs under this arc, the ISO Member Body of the country needs to send a letter to ISO/IEC JTC 1/SC 6 to inform about which organization in the country has been chosen as the Registration Authority for the country arc, so that the register of the superior OID can be updated (see What decision needs be taken if a country wants a national Registration Authority for OIDs?).
This arc was deprecated in favor of
{joint-iso-itu-t
country(16)}.See the list of known country registration authorities for OIDs.
