DCNC - Appendix #2ab - Territory Codes
If you have a DCP and you need to determine its territory, use this table. If you are creating a DCP and you need to know what code to use for a territory, use this table. For countries not in this table, try https://www.iana.org/assignments/language-subtag-registry/language-subtag-registry. Country codes are based on ISO 3166-1 country codes whenever possible. Exceptions are denoted with a “Tag Scope”.
Special Exception Note: OV (Original Version) is a territory agnostic “base” package. Some studios use this as a package that can be used in many territories by applying VF files to customize to specific territories. It is a recent addition to document practice in the field, not necessarily a recommendation. In this case, as per 429-16 for ReleaseTerritory metadata: “…for generic international versions, the code ‘001’ shall be used.”
