# Mask customer numbers

> Hide customer phone numbers from agents who don't need to see them.

Turn on number masking per-user to hide customer phone numbers from specific agents. Useful for privacy compliance or when agents don't need direct access to contact details.

## Before you start

* Admin permission to manage users

## Steps

<Steps>
  <Step title="Open Account -> Users">
    Navigate to the users list.
  </Step>

  <Step title="Open the user">
    Click the user you want to configure to open the user drawer.
  </Step>

  <Step title="Enable Hide contact details">
    Check the "Hide contact details" option.
  </Step>

  <Step title="Save">
    The agent will no longer see customer phone numbers in the chat view.
  </Step>
</Steps>

## Tips

* Masking is configured per-user, not per-role — set it individually for each agent who needs it.
* Agents with masking on can still send and receive messages; they just cannot see the full phone number.
* To remove masking, uncheck "Hide contact details" for the same user.
