Caller Identification

Customer contact data changes constantly, making it difficult for CSPs and businesses to keep up-to-date records. High telephone number churn creates a constant accuracy problem for CSPs and businesses. When numbers are updated, name data may lag by days or weeks, leading to:

•   Wrong-party calls
•   Low call answer rates
•   Increased spam mislabeling
•   Regulatory and compliance risk

Caller ID solutions help CSPs and enterprises continuously reconcile phone number ownership and name data so they can keep pace with this volume of change.

With Caller ID, best-in-class data, information services and analytics capabilities apply proprietary methodologies to aggregate, build, cleanse and manage data to clearly and efficiently display the caller’s identity. As technology advances, so do TransUnion identity solutions to make it easier for CSPs to manage phone numbers and associated caller names (CNAM) and make them available to the entire call ecosystem of carriers and mobile app providers. That helps ensure identity is vetted to help restore trust and reduce voice fraud.

The Line Information Database (LIDB) ensures accurate Caller ID by acting as a centralized, repository for telephone numbers and the associated subscriber names (CNAM). When calls are made, the terminating carrier queries the LIDB for the accurate, up-to-date name, enabling reliable display of business or individual identities and reducing call spoofing. Transunion operates the biggest neutral and independent line information database in North America, processing 11 billion queries monthly with 99.999% uptime.

Caller Identification helps CSPs transform caller ID services from an operational cost to a trusted competitive advantage. Registering Caller Name (CNAM) data ensures accurate caller information is displayed, reducing confusion as well as the number of trouble tickets with complaints about "unknown" or incorrectly labeled numbers.

There’s a lot of confusion over Caller ID vs. branded Caller ID vs. branded calling for businesses. Today, due to the rapid rise of call spoofing and fraud, more and more businesses are looking for solutions and technologies like branded calling for business with rich call content through which calls are branded and authenticated with STIR/SHAKEN and end-to-end authentication. This enables customers to really trust who’s calling and increases the likelihood of them answering the phone.

Close to 35 to 45 million US telephone numbers are disconnected and reassigned every year, sometime due to switching carriers, canceling service or moving. That means nearly one in eight US phone numbers changes ownership annually. Close to roughly 2 million CNAM updates are made per year across US carriers.

To increase response and confidence in customer connections, communications service providers (CSPs) need robust, accurate caller name services to provide visual cues for subscribers so they know when a call or text can be trusted.
