Caller Name (CNAM) refers to the caller ID name that's displayed on an incoming phone call. This article explains how you can use the Bandwidth Dashboard to enable or disable CNAM on up to 5,000 phone numbers at once. For API information, please see our developer docs.

Note: You can determine which of your phone numbers have CNAM on or off by looking at the CNAM column in your Full Phone Number Details report.

To enable or disable CNAM on phone numbers:

  1. Log into the Bandwidth Dashboard.
  2. In the top navigation bar, click Numbers and select Upload Line Features.
  3. Click download a template .csv file. This will download the CSV file into your web browser.

Note: If you don’t see the file, please make sure your browser is set to allow pop-ups from the Bandwidth Dashboard and try again. If you still can’t locate it, check the Downloads section in your browser or the Downloads folder on your computer.

  1. Once you open the template, you'll see sample data that shows how the file needs to be filled out for various features. Please erase all information in rows 3-6 prior to entering your own. 
  2. In the TN column, enter the phone number(s) where you want to enable or disable CNAM. Please use the 10-digit format without spaces, parentheses, or dashes.
  3. In the CNAM column, indicate whether you want to enable or disable CNAM by typing on or off.

  1. Once you're done, save the file in the .csv format and return to the Upload Line Features page.  
  2. Drag and drop the file into the Choose a .csv file to import field or click Browse to search for it on your computer.
  3. Enter an optional Customer order ID that can be used to identify any orders created as a result of this file import.
  4. Click Import to upload your file.

Note: If you encounter any errors, please double-check that the formatting is correct. Errors may occur due to an incorrect file type (anything other than .csv), spaces in the file name, or formatting issues in the file itself.
