Is a homeowner's number displayed if it is on the National Do Not Call registry?

Some listings in RPR display a phone number in the Homeowner Facts section of the Property Details page. These phone numbers have been checked against  the National Do Not Call Registry, as mandated by the federal government, and would not display if the homeowner has entered that preference with the registry.

When an owner’s phone number is available with a listed property, the number is clickable within the RPR Mobile app, allowing the user the ability to touch and dial the seller. This option is only available when an MLS includes this information with the listing data.
