Is it possible to change the telephone number format?

Is it possible to change how telephone numbers are displayed in the "Family" section? The default format looks a bit unfamiliar to UK users.


  • Hello, this is a very good question, and I am sure there are some formatting tools out there that can do this for us. As an example, can you show how you'd expect a UK phone number to be formatted? Thanks, Ross.
  • A typical UK fixed phone number in my area would be formatted like this:
    01223 502312 (this is an invented number so far as I know!)

    The first 5 digits are the area code and the last 6 digits are the actual number.

    The international version of this could be either 0044 1223 502312 or +44 1223 502312

    A problem I can see with this is that the area code is not always 5 digits so for example a London number would be of the form ‎020 xxx xxxx (0044 20 xxx xxxx) Other bigger cities use a similar format to London.

    Mobile numbers are 07xx xxxxxxx (00447xx xxxxxxx or +447xx xxxxxxx)

    Its all a bit of a mishmash I'm afraid and not very standardised but hopefully something could be done to the formatting to make UK numbers appear more like they are normally written here.

  • Thanks for the example. This makes sense, and although we wouldn't necessarily be wanting to code up all possible alternatives ourselves, there seem to be some libraries available to do this kind of formatting.

    @sandra what do you think about using the following library, which we could use with the table rewrite:


  • I am also interested in changing the phone number display preferences. I would like to see (555) 555-5555 to match phone numbers in the US. Has that library been able to offer the options?

  • Hi Kevin, this one got overlooked in the push to get v18 out the door. @sandra something for v19? Ross
  • Sounds do-able for v19. I've added it to the feature request planning board:
