Where I am there is no consistent way of saying or writing a phone number. In my job, I deal with phone numbers a lot and I got in the habit of writing them down in the American way, 4-3-4 digit pattern so that I can tell right away if there are enough digits. On our website, phone numbers are written in many, many different ways. It drives me nuts. (on our section though, it's always 4-3-4 because I look after it!).
