# Unknown Numbers Discovered in Campaign's Destinations

> If unexpected phone numbers show up in your Destinations tab, a form field or widget on your site may be making them discoverable — exclude that URL from number discovery to fix it.

## Symptoms

* Numbers don't display within the webpage source code.
* No numbers appear when running `Invoca.PNAPI.display()`.

**Applies to:** Destinations

## Cause

Check how customer forms or map widgets on your website interact with the Invoca Tag. If customers enter numbers somewhere on your site, the Tag may treat those numbers as discoverable and list them in your Destinations tab.

## Resolution

If numbers are being found on specific pages, exclude those URLs from number discovery:

1. Navigate to the Invoca Tag.
2. Edit the current version of your Tag.
3. In the Website Phone Numbers section, below the default campaign, find "Exclude URLs for discovering numbers."
4. Enter the URL of the page you don't want numbers discovered on.
5. If you have multiple URLs, separate each one on its own line.
