vCard Icon Creator
Icon Creator Icon List
There's over 5000 icons that you can choose from when using vCard Icon Creator to create your icons.
vCard Menu Creator obtains the icons from your device using the Actions application so depending on your iOS/iPadOS version, some icons might not be available.
You can check the list of icons available and their names using the SF Symbols app from Apple. Always check the "Availability" section to see if the device you're running vCard Menu Creator from has the icon available.
