Free Phone Number Lookup Tool and API - Instant AI Phone Validation

How to Use Our Free Phone Number Lookup and AI Validation Tool

Our free phone number lookup and validation tool is designed to make phone verification seamless. Users can input a single phone number or multiple numbers, even in unstructured formats, and our AI will intelligently clean, parse, and validate the numbers. Whether the input includes missing country codes or formatting errors, the tool assigns the correct country code based on contextual clues (e.g., predominantly UK-based numbers will assume UK codes for missing ones). It returns detailed validation data, including carrier information, caller name (CNAM), and Do Not Call (DNC) registration, allowing you to efficiently clean and verify your contact list.

Key Features of Our Phone Lookup Tool

• E.164 format conversion: All phone numbers are returned in the E.164 international format for consistency and compatibility with global systems.
• Fraud detection: Identify potentially fraudulent phone numbers before use, reducing the risk of high-risk interactions.
• Carrier lookup: Get detailed carrier information, including mobile network and country codes, to enhance your communication strategy.
• Portability checks: Determine if a phone number has been ported to another carrier to keep your data up to date.
• Real-time lookup: All lookups are performed instantly, providing accurate and real-time information on the phone numbers you validate.

API Integration for Automated Phone Number Verification

Our phone number lookup tool also comes with a free API that enables developers to integrate phone validation directly into their platforms. This API simplifies phone verification for CRM systems, mobile apps, and web forms. Our API is free to use, and no API key is required, making integration faster and easier.
