Create a RingPool of local (U.S. and Canada) phone numbers, letting you capture individualized marketing data from each visitor’s call.
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 local (U.S. and Canada) phone numbers.

​
Creating a local 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 Local, then click Next.
  7. In the Target Area for Local Number field, enter a city, area code, area code and local prefix, or zip code.
  8. To limit results by distance, check Restrict search and enter a radius in miles, then click Next.
  9. If your target area spans more than one area code, you’ll see a list you can drag and reorder — Invoca fills your RingPool from each area code in the order you set.
    • To exclude an area code entirely, hover over it, click its menu button, and select Delete a Number.
    • To see where an area code is located, hover over it, click its menu button, and select View area code on a map.
    • A yellow caution icon next to an area code means Invoca doesn’t currently have enough numbers there to fill your RingPool. Choose whether to wait for local numbers or use toll-free numbers in the meantime — Invoca always shows local numbers to visitors first when both are available.
  10. Click Next when finished.
  11. 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 Local 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 Local RingPool’s size, name, and attribution parameters, but not its location. If you reduce its size and it contains both toll-free and local numbers, numbers are removed at random regardless of type.

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.
