Updating Your Outbound Caller ID Name (CNAM)
Overview
Your Outbound Caller ID Name (CNAM) is the name displayed to a recipient when you place an outbound call. Sharpen can submit CNAM update requests on your behalf for eligible numbers by completing and submitting a LIDB (Line Information Database) form to the Sharpen Care team.
The Caller ID name displayed to a recipient is ultimately determined by the receiving carrier's database. Some carriers may take longer to reflect updates depending on their own refresh schedules.
