Nickname or change profile name on multiple lines

You will need to schedule a callback through Koodo Assist first and speak with a rep to see if that is possible. Once that is done, you can give authority to someone else to make changes on your Self-Serve account. https://www.koodomobile.com/en/help/permissions

Koodo doesn’t let you set nicknames or change profile names for individual lines in your account. All lines show the main account holder’s name. No workaround exists in Self Serve or online. If you need separate names, each line would need its own account. 

​@tommer65 Milkyway is right.  You can request a callback and a rep can change the name for each line
