Caller ID names (also called CNAM) are connected to phone numbers in your account. Each phone number can have a 15 character name (including spaces). The name and numbers are displayed when you make an outbound call to a user that has caller ID. You can view the current caller ID name and request a change in the Number tab on a number's option page. Check out our caller ID guide for more information.
