# Toll-Free RingPools

> Create a RingPool using toll-free U.S. and Canada phone numbers, not tied to any specific local area code.

A RingPool is a group of phone numbers in your account served uniquely to your customers, letting you capture individualized marketing data from their calls. This article covers creating a RingPool using toll-free (U.S. and Canada) phone numbers, which aren't tied to any local area code.

## Creating a toll-free number RingPool

1. Log in to your Invoca account, click **Campaigns**, then select **Manage Campaigns**. Select the campaign where you want to create your new RingPool.
2. Click the **RingPools** tab, then click **Add New RingPool**.
3. In the Name field, name your RingPool — this appears in your Invoca reports in the Promo Number Description column.
4. In the Number Session Lifetime dropdown, choose how long to reserve a phone number for each unique visitor. A shorter time supports more unique visitors with fewer numbers; a longer time improves accuracy.
5. In the overflow settings section, choose how to handle visitors beyond the size of your RingPool.
6. Under Number Type, select **Toll-free**, then click **Next**.
7. If you use Marketing Data, enable "Use Marketing Data for attribution," or enter up to 10 URL parameters or cookies to track with this RingPool instead. Click **Save & Next** — your RingPool API URL also appears here if you use the RingPool API.

Once created, test your Toll-Free RingPool's composition before deploying your landing page live — using the RingPool API, your test environment, or by reaching out to your account team or [support@invoca.com](mailto:support@invoca.com).

You can later edit a Toll-Free RingPool's size, name, and attribution parameters, but you can't convert it to use local phone numbers instead.

## Using RingPools on performance marketing landing pages with WIC

If your RingPool is used on a landing page managed by an Advertiser deploying Web Integration Code (WIC), click the **Get Link** tab to access the tracking link, including mobile click-to-call. Advertisers can also use the RingPool without the link by adding the Campaign ID and RingPool ID parameters to the Web Integration Code, available on the **Get Code** tab.
