Phone Number Format Guide is a free, web-based reference directory that provides correct local and international phone number layouts, E.164 values, and copyable example numbers for more than 200 countries.
What is Phone Number Format Guide?
Phone Number Format Guide is a self-contained web app that answers the question "What phone number format do I use for this country?" You select a country, and the site displays the local dialing format, the international format, the E.164 representation, and a realistic example number that you can copy. It runs entirely in the browser, requires no signup, and is freely accessible. See example pages for the United States, the United Kingdom, India, Canada, Australia, and Japan.
