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. 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.
