# ip.src.subdivision\_1\_iso\_code

`ip.src.subdivision_1_iso_code` String

The ISO 3166-2 code for the first-level region associated with the IP address.

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

Requires a Cloudflare Business or Enterprise plan.

For more information on the ISO 3166-2 standard and the available regions, refer to [ISO 3166-2](https://en.wikipedia.org/wiki/ISO_3166-2) on Wikipedia.

This field has the same value as the `ip.geoip.subdivision_1_iso_code` field, which is deprecated. The `ip.geoip.subdivision_1_iso_code` field is still available for new and existing rules, but you should use the `ip.src.subdivision_1_iso_code` field instead.
