When tagging a country, ISO3166-1=* indicates an ISO 3166-1 country code of that country. You can use the ISO Online Browsing Platform to lookup these codes.
This tag can be added to:
- a node representation of the country (usually tagged as
place=country); - a boundary relation of the country (usually tagged as
boundary=administrativeandadmin_level=2).
Use more specific keys to differentiate different types of ISO 3166-1 codes
ISO 3166-1 defines multiple types of country codes. You can use more specific keys to differentiate these different types, both as a mapper and as a data consumer:
ISO3166-1:alpha2=*for two-letter codes;ISO3166-1:alpha3=*for three-letter codes;ISO3166-1:numeric=*for three-digit codes.
In practice, the ISO3166-1=* key is used in the same way as ISO3166-1:alpha2=*, i.e. indicating the two-letter code. The latter key has the advantage that this intention is made explicit. For backward compatibility, data consumers looking for two-letter country codes can first read ISO3166-1:alpha2=* and fall back to ISO3166-1=* if ISO3166-1:alpha2=* is not available.
