VoIP CNAM (Caller ID Name) Requirements

CNAM is used in U.S.-based telephone networks to display your company name to the recipient when you call.

IMPORTANT: This is limited to 15 characters, including spaces, if you provided a long company name, we will use only the initial words that fit within the limit.

At this time, CNAM feature is mainly supported with US carriers.

This process can take up to eight weeks.

Subject Line: CNAM / Caller ID Request

Once provided, we'll submit your request to our telephony provider and let you know once your submission has been approved.

I would also caution you against thinking that this will make it guaranteed that registering a CNAM will make your CallerID Name be displayed in every instance.

CNAM is not a mandatory standard, and some carriers either do not enable it by default or only offer it for certain clients, or require the use of a special app on the client's phone. This is especially common for mobile carriers. The situation there is improving, and more and more people should be able to see your CNAM displayed, but it's not a guaranteed outcome.

At this time, CNAM feature is mainly supported with US carriers.
