• Twilio's CNAM display name can be at most 15 characters, must begin with a letter, and may contain only letters, numbers, periods, commas and spaces. in context
• Twilio says CNAM displays by default on landlines, but most US mobile carriers require the recipient to opt in, so an unenabled mobile phone will not show a correctly set CNAM. in context
• After approval, a Twilio CNAM display name can take 48-72 hours to propagate to US carriers, and display depends on which CNAM databases the recipient's carrier subscribes to. in context
