About Abstract Phone Validation
Abstract Phone Validation is an API that checks whether a phone number is real, returning details such as validity, carrier, line type (mobile, landline, or VoIP), registered location, country, and both local and international formats. It is designed to catch fake and invalid numbers before they enter a database or contact system, and covers phone numbers across more than 190 countries.
The service is aimed at developers who need to validate and verify phone numbers programmatically, for example to maintain clean contact lists and screen out disposable, free, or VoIP numbers. It includes free tools for phone number lookup, carrier lookup, and line type checking, alongside the core validation API. A free tier offers 100 requests without requiring a credit card.
Abstract also provides a broader suite of related APIs, including email validation, email risk scoring, IP intelligence and geolocation, VAT and IBAN validation, and website screenshot and web scraping tools, offered under the same platform.
