Where do I find updating information on ISO 3166-1 and ISO 3166-2?
We publish newsletters on ISO 3166-1 and ISO 3166-2 which are authoritative updates on the currently valid edition of ISO 3166-1 and ISO 3166-2. An ISO 3166-1 Newsletter is published whenever a change to the country names and/or country codes is effected by the ISO 3166/MA. This implies that if there are no changes to the list in the standard we won’t publish newsletters. The same applies to ISO 3166-2 Newsletters.
