We are considering changing the phone number formatting to help give the end user more control over how phone numbers are shown when formatted.
This will allow UK, European, Australian, and other users to also format their phone numbers, as well as giving US/Canadian users the ability to alter the default formatting. Doing this will eliminate the Default Area Code field, so I wanted to get a rough idea of how many people actually use that. Please take a moment to let us know whether or not you currently use the default area code.
