I am constantly criticized and asked to change the way I format telephone numbers. People always think that the way they do it is best.
Most of the time, I prefer this format: (480) 945-5653.
So that’s what I use when I put a phone number on a web site or printed piece.
But 99% of the time the customer asks me to change it.
Sometimes they want it like this: 480-945-5653. The rest of the time, they like using periods between numbers, like this: 480.945.5653.
Then there are people who want to use some wicked combination. My favorite is separating the numbers every two digits. As such: 48 09 45 56 53. Yes, that is beautiful.
