All projects matching “validate phone number”

Parse, validate and format a phone number — E.164/national/international/RFC 3966, region and line type (syntactic validation, no carrier lookup).

International phone number validation and normalization (libphonenumber): validity, country, E.164, national/international formats and line type.

Phone number intelligence for agents: pass any number and get back whether it is a valid E.164 number, its country, the carrier that holds it, and the line type — mobile, landline, or VoIP. One paid call, no account, no API key. Decide whether a number is worth calling or texting, or flag a VoIP number before you trust it. Free-format numbers are normalized; a syntactically bad number is rejected
