To find the OID corresponding to the ISO 3166-1 alpha-2 code of a country, please click on the numeric code at the intersection of the row corresponding to the 1st letter of the alpha-2 code of that country and the column corresponding to the 2nd letter (see highlighted example for "AD").

Note: Not all countries have yet established a registration authority (RA) to assign OIDs beneath their national OID (see the known country RAs and the process to be followed for establishing such an RA).
