National Caller ID CNAM Database
November 26, 2023 / Written by Angela Garfinkel

Phones buzz with incessant calls, distinguishing the important ones from a sea of robocalls has become a daily challenge. For consumers, the frustration is palpable - an unknown number often signifies yet another unwanted interruption. In 2022, U.S. consumers received over 50.3 billion robocalls, with roughly 41% of overall robocall volume being scam or spam calls. This widespread aversion impacts not just individuals but also legitimate businesses, whose genuine calls are often lost in the shuffle, mistaken for yet another nuisance. The FCC's implementation of STIR-SHAKEN has helped slow down this increasingly problematic issue, but let's learn about the CNAM National Caller ID Database and how it helps.


What is the National Caller ID CNAM Database?

The National Caller ID CNAM Database serves as a centralized system that holds information about registered phone numbers across the United States and Canada. This database is integral to the process of identifying and displaying the names associated with phone numbers during outbound calls. Whenever a call is made, the respective carrier taps into this database to fetch and display the registered name of the caller on the recipient's phone. This feature is particularly crucial in the current age, where anonymous calls often raise suspicions of being spam or fraudulent.

A national database for caller identification, like the CNAM, exists primarily for ensuring transparency and security in telecommunications. In an era where phone scams and unsolicited calls are common, having a verified name attached to a number helps users distinguish between legitimate calls and potential fraud. The CNAM database acts as a shield against these unwanted calls by providing clarity on the caller’s identity.


How The CNAM Database Is Used

The CNAM database is used every time a call is made and received. When someone calls, their service provider queries this database to retrieve the name associated with the calling number. This name is then displayed on the recipient's caller ID, alongside the phone number. This process occurs in real-time, ensuring that caller ID information is up-to-date and accurate.

The primary users of the CNAM database are telecommunication service providers and carriers. They access this database to offer caller ID services to their customers, ensuring that each call comes with a name attached. This feature is fundamental to the service they provide, as it enhances call security and user experience.


How Do I Check My Own Caller ID Name?

To check or update your caller ID name, you typically need to contact your phone service provider. Most carriers have a process for customers to request changes to their CNAM entries. This might involve logging into your account on the provider’s website or contacting customer service. The process is generally straightforward and is an important aspect of maintaining your telephonic identity.
