When the actual value is not available, this field contains an empty string.

Requires a Cloudflare Business or Enterprise plan.

This field has the same value as the `ip.geoip.subdivision_2_iso_code` field, which is deprecated. The `ip.geoip.subdivision_2_iso_code` field is still available for new and existing rules, but you should use the `ip.src.subdivision_2_iso_code` field instead.
