Phone Number Validator

Parse, validate and format phone numbers to E.164 - fully offline, no per-lookup fees.

betaData ValidationAvailable on RapidAPI

Parses a phone number to E.164, detects the country by calling code, validates the national-number length against bundled per-country rules, and returns international/national/E.164 formats. Deterministic and offline - no carrier API required. IMPORTANT: this validates STRUCTURE (calling code + digit length), NOT whether the number is live or assigned. Live/ported-number checks need paid carrier lookup data which this API does not provide. Metadata: all global dial codes covered; ~199 of 205 entries carry researched per-country length rules, 6 use a permissive 4-15 digit generic fallback.
