# Assign DID numbers to a capacity group

Assign DID numbers to a Capacity group so they can use the group's shared channels, metered channels, or both.

## Before you begin

- Create the Capacity group before assigning DID numbers to it. See [Create a Capacity group](../../capacity/how-to-guides/create-capacity-group.html).
- Choose a Capacity group in the pool that matches the DID numbers you plan to assign. For pool and group behavior, see [Capacity groups](../../capacity/capacity-groups.html#capacity-groups).
- Only DID numbers that support additional Capacity can be assigned to a Capacity group. For capacity modes and channel priority, see [How capacity works](../../capacity/how-capacity-works.html).

Use this flow to assign one or more DID numbers to an existing Capacity group.

## Step 1: Select DID numbers

1. In the DIDWW User Panel, go to **Phone Numbers > My Numbers**.
2. Select the DID numbers you want to assign to the Capacity group.
3. At the bottom of the page, click **Batch Actions**.
