Phone Validation

API

Global phone number validation and metadata API

Overview

The Phone Validation API by AbstractAPI offers a RESTful endpoint to validate phone numbers across 200+ countries. Its core endpoint (/v1/validate) accepts a phone number (with optional country code for precision) and returns JSON responses with details like validity status, country origin, carrier name, line type (mobile/landline/toll-free), and formatted variants (E.164, national). Use cases include user onboarding verification, fraud prevention in e-commerce, CRM data cleaning, and ensuring SMS/MMS delivery success by confirming active, valid numbers.
