Number Verify

About this API

In today's digital applications, a phone number is a core part of a user's identity. The Number Verify API is more than just a simple format checker; it's the first line of defense for your application's security and data quality. Leveraging an up-to-date international numbering database synchronized with global telecom carriers, this API can validate the authenticity of any phone number in real-time. With a single API call, you can confirm if a number is real, identify its current carrier, determine its line type (mobile, landline, or VoIP), and find its geographical location. Integrating this API means you can capture quality leads, keep your user database clean, and effectively combat fraud from the source, protecting your business from spam registrations and fraudulent activities.

Key Features

• Global Validation Coverage: Supports real-time validation for international and national phone numbers in most countries worldwide.
• Carrier & Line Type Identification: Accurately identifies the number's current carrier and determines its line type (e.g., mobile, landline, voip), which is crucial for assessing fraud risk.
• Geographic Location Lookup: Returns the country name, code, and location associated with the number, providing data to support content localization and regional operations.
• Real-time & Secure: All requests are secured via 256-bit HTTPS encryption, ensuring secure data transmission, with results returned in a lightweight JSON format.
• Simple Integration: Features a simple RESTful API architecture and an intuitive URL structure, allowing for easy integration into any web form, user registration process, or backend service.

Use Cases

Scenario 1: Build a Frictionless and Secure User Registration Flow

Situation: A fintech or social media app needs to verify phone numbers during user registration to prevent fake accounts and abuse. Implementation: When a user submits the registration form, the application backend calls the Number Verify API. The API instantly confirms the number's validity and, more importantly, checks the returned line_type field. If the number is a voip or disposable type, the system can flag it as high-risk, request additional verification, or deny registration. This is more efficient and secure than sending an SMS OTP, as it intercepts fraud before it happens and avoids costs from sending messages to invalid numbers.

Scenario 2: Improve Lead Quality in Sales and Marketing Automation

Situation: A B2B software company wants to improve the quality of leads collected from its "Contact Sales" form. Implementation: After a potential customer submits the form, the system automatically triggers a call to the API. The API validates the phone number, ensuring the sales team doesn't waste time on incorrect numbers. Additionally, the returned location and carrier information can enrich the customer profile in the CRM. For instance, leads can be automatically assigned to the correct regional sales team based on location, reducing response time and increasing conversion rates.

Scenario 3: Simplify Password Recovery and Account Access

Situation: An e-commerce platform wants to offer a more secure and convenient password recovery option than traditional email verification. Implementation: When a user opts to recover their password via phone number, the platform can use this API for a "silent verification." By checking with the carrier network, the API can reliably confirm that the user possesses the SIM card for that number without requiring any manual code entry. This network-based identity verification is more secure than SMS OTPs, which are vulnerable to interception, providing a seamless user experience and enhancing account security.

How it Works: Endpoints & Response

This API provides several endpoints, such as the validate endpoint for single number verification. Another useful endpoint is countries.

Endpoint Example: https://hub.juheapi.com/number-verify/v1/validate

Developers can call this endpoint to retrieve a list of all supported countries, including their names, international dialing codes, and number formats. This is particularly useful for building user interfaces, such as pre-populating a country code dropdown on a registration page to guide users toward entering a correctly formatted number from the start.
