CNAM (Caller Name Delivery) is a telephony feature that allows displaying the caller’s name in addition to their number. When an outgoing call is made, the recipient can see not only the number calling them but also the associated name (for example, your company’s name).

This information is retrieved from telecom databases (Line Information Databases), which link a phone number to a name.

⚠️ CNAM management via Ringover is only available in the United States 🇺🇸.

1. What is the difference between CNAM and CLID?

CLID (Caller Line Identification): corresponds to the display of the phone number.
CNAM: adds the name associated with that number, allowing the recipient to more easily identify who is calling.

2. What are the benefits of CNAM?

Activating CNAM on your numbers provides several advantages:

Clear caller identification: the recipient immediately knows who is calling.
Reduced ignored calls: a call identified by the company name inspires more trust than an unknown number.
Improved customer experience: the conversation starts more smoothly, without having to repeat your company’s name several times.
Spam flag prevention: a call with a visible name is less likely to be perceived as suspicious.

3. Are there any limitations to CNAM?

The display of the name may vary depending on the country and the recipient’s phone carrier.
Some phones or subscriptions do not support CNAM.
The displayed name must be short and clear (often limited in number of characters).

4. How does Ringover manage CNAM?

Ringover allows you to configure and associate a company name with your numbers so that it appears during outgoing calls, when supported by the destination network.
Our teams also assist with verifying the display to ensure that your calls are properly identified.

5. Best practices to follow

Choose a simple and recognizable name (for example, your company’s full name).
Avoid complicated or overly long abbreviations.
Regularly check the CNAM display across different networks and devices.

🎉 CNAM is therefore a simple yet effective way to make your outgoing calls clearer and more trustworthy for your contacts.
