Format real phone numbers
In the rare case when you're providing a real phone number to contact a real person, use the following formats, depending on whether the number is in North America or elsewhere.
North American phone numbers
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.
International phone numbers
To format phone numbers in non-NANP countries, include the country and area codes. Separate the groups of digits with nonbreaking spaces. Insert a plus sign immediately before the country code (no space); the plus sign stands in for a prefix known as an exit code, which lets you dial out of a country. Each country has a different exit code.
