The ID App allows the setting of a short 14 character maximum ID.
ID (Fixed or Flex)
A text ID entry that will display when scanned. Maximum length of 14 characters. Can be set as Flex so that it can be updated at any time after a scan, or Fixed and so it can never be updated.
Set your own title. You can also delete the title completely to have no title.
Flex will allow you to change the ID if required. Fixed will mean that you cannot ever change the ID.
