Overview
Parse and validate any phone number in any format, identify its country and line type (mobile/landline/VOIP/toll-free/premium for NANP + UK numbers; other countries return line_type unknown), and return all standard format variants (E.164, international, national) — catches fictional/unassigned NANP numbers (555 area code, 555-01XX range) so agents can validate contacts and normalize phone data without a paid telecom API.
