What is the right format for a phone number?

To format phone numbers in the US, Canada, and other NANP (North American Numbering Plan) countries, enclose the area code in parentheses followed by a nonbreaking space, and then hyphenate the three-digit exchange code with the four-digit number.

Do you put 0 after 44?

44 is the country code for the UK. 0 is the long distance dialling code within the UK, from STD (subscriber Trunk Dialling) used to access the 'long distance' or trunk network. You don't need it if dialling the UK from overseas as the call arrives already on the trunk network.

How do you write an 11 digit phone number?

If you do not want the parentheses-space-hyphen formatting (800) 555-1212 for a 10- or 11-digit number, enter a “+” before the number. You can find more documentation on phone number formatting in Salesforce here.
