Every so often I rue being an unsophisticated American. This is one of those times.
I have been tasked with creating a one-off business card design for an (American) colleague who will be visiting a French-speaking African nation. My question: what is the proper way to format his US-based telephone number for international distribution?
Note: I am not asking any questions on how to dial a phone number. This is a question of visual presentation. That is, what is the proper format, spacing, and punctuation to use – including proper usage of the plus sign, parentheses, hyphens, and spaces?
Online searches turn up plenty of help on how to dial internationally, but I’m finding it difficult to get a solid answer on the proper protocols of including the country code and how, precisely, to most helpfully group and space the digits. My best guess, before being blessed with the wisdom of the Dope, would be: +1 (202) 867-5309. Now set me straight!
