# Blocklist

## Overview

Blocklist is an anti-spam tool that allows users to prevent specific phone numbers from connecting to their IVR applications.

{% hint style="warning" %}
At present, Blocklist only works with Plum Dev. Support for Plum Fuse is under development.
{% endhint %}

Plum Dev users can contact their [Plum Account Manager](mailto:accountmanagement@plumgroup.com) to obtain access to Blocklist.

Users can access Blocklist via the [web portal](/blocklist/blocklist-web-portal.md), or by using the [Blocklist API](/blocklist/blocklist-api.md).
