Phone number format standards
E.164 is the international standard: a leading +, country code, and subscriber number with no spaces or punctuation (e.g. +15558675309). It's the format required by most telephony APIs. National format uses local conventions (e.g. (555) 867-5309 for the US).International format adds the country code with spaces for human readability.
