Phone Number Validator checks a phone number and returns whether it is valid, its line type, country, area and time zone, and the carrier its mobile range was allocated to. It flags disposable and VoIP numbers and outputs E.164, international, national and RFC3966 formats.
The Phone Number Validator API provides a simple, reliable way to integrate phone number validator functionality into your applications. Built for developers who need production-ready phone number validator capabilities without the complexity of building from scratch.
Quick Start
Using JavaScript
async function callPhoneNumberValidatorAPI() {
try {
const params = new URLSearchParams({
number: '816-555-1017',
country: 'us'
});
const response = await fetch(`https://api.apiverve.com/v1/phonenumbervalidator?${params}`, {
method: 'GET',
headers: {
'x-api-key': 'YOUR_API_KEY_HERE'
}
});
const data = await response.json();
console.log(data);
} catch (error) {
console.error('Error:', error);
}
}
callPhoneNumberValidatorAPI();Using cURL
curl -X GET "https://api.apiverve.com/v1/phonenumbervalidator?number=816-555-1017&country=us" \
-H "x-api-key: YOUR_API_KEY_HERE"Get your API key: https://apiverve.com
