Overview
Phone number validation and formatting. Checks a phone number against the national numbering plan and returns whether it is valid and possible, its E.164, national, and international formats, country calling code, region, line type, and time zones. Accepts +E.164 or a national number with a country code. Numbering-plan validation only, not a live-line check. Keyless.
