Veriphone

Overview

Veriphone validates international phone numbers — format, carrier, country, line type, and validity — with a simple JSON API. Auth is a free API key (an invalid key returns 401, verified).

Quick Start

Verify a number (replace YOUR_KEY):

{
  "phone_valid": true,
  "phone_type": "mobile",
  "phone_region": "US",
  "carrier": "Verizon",
  "international_number": "+14155552671",
  "local_number": "4155552671",
  "country_prefix": "+1"
}

Authentication
