PhoneVerify

PhoneVerify is a UK phone number validation service that helps businesses identify and remove bad phone records from their datasets before those numbers reach CRM systems, call centres, or SMS marketing campaigns. It addresses the common problem of disconnected, non-existent, or incorrectly formatted numbers that waste calling time, increase SMS costs, and lower campaign performance.

The service validates both mobile and landline numbers using telecom network lookup technology, classifying each number into one of six statuses: Active, Inactive, Absent, Ambiguous, Unknown, or Invalid. Users can upload CSV or Excel files for bulk verification, validate numbers in real time via an API, or integrate validation directly into web forms using a lightweight SDK. Additional capabilities include scheduled re-verification (monthly, quarterly, or six-monthly), downloadable verification reports with dataset quality insights, and integrations with platforms like Zapier and WPForms.

PhoneVerify is aimed at teams that rely on phone data, including call centres, SMS marketers, CRM managers, and data providers. It uses pay-as-you-go pricing with no subscriptions, charging per number verified with volume discounts applied automatically based on job size. A minimum job charge applies, and enterprise pricing is available for high-volume users.
