# How to Set a Phone Number for a Workflow

This guide explains how to assign a specific phone number to a workflow. The selected number will be used to send all messages triggered by that workflow.

Follow these steps to select the phone number that your workflow will use to send messages. If you are a **Sole Proprietor**, you can also use this setup to ensure that only your **A2P-verified number** is used when sending automated messages.  
  
**Steps:**

1.  Go to **Automation** and select the workflow you want to set up.
