# Ens.labelhash

:::info
`Ens.labelhash` is a re-export of ox's [`Ens.labelhash`](https://oxlib.sh/api/Ens/labelhash). Refer to the ox documentation for the full reference.
:::

Hashes ENS label.

Since ENS labels prohibit certain forbidden characters (e.g. underscore) and have other validation rules, you likely want to [normalize ENS labels](https://docs.ens.domains/contract-api-reference/name-processing#normalising-names) with [UTS-46 normalization](https://unicode.org/reports/tr46) before passing them to `labelhash`. You can use the built-in [`Ens.normalize`](/docs/utilities/ens/normalize) function for this.
