What are Add-ons?

Add-ons are features of the PhoneID API that allow you to get additional information about a phone number along with the base details. You can add them to your request to get detailed information about phone numbers, such as device details, porting history, subscriber contact information, and more. The self-service API only supports the Contact add-on. For more details, see Get Started with Add-ons.
