Without an authoritative database for Calling Name Delivery (CNAM) in North America, carriers rely on a multitude of CNAM providers to retrieve and present the Calling Name that is associated to a Caller ID. Old or inaccurate data negatively effects the end user subscriber’s experience of the call and can lead to phone calls not being answered. NetNumber has partnered with First Orion, market leader in call identification services, to deliver a best-inclass CNAM service. The North American Calling Name Service produces over 70% coverage of all North American telephone numbers due to its comprehensive name database, advanced knowledge algorithms, and smart truncation. This far exceeds traditional network CNAM capabilities. Onboard data is updated every hour, eliminating the need to send referral queries to remote services for up to 80% of all CNAM lookups.
