Numverify enables you to verify the phone number by simply passing it into the API’s request URL. So, it has made the validation process very simple. Next, let’s take a look at how you can implement the free phone number lookup API into your PHP and JavaScript web applications.
What do I do to integrate Numverify into my PHP web application?
1. First, you have to set API Access Key, which you can get for free by signing up here.
$access_key = ‘YOUR_ACCESS_KEY’;
2. Then you have to specify the phone number that you want to verify.
$phone_number = ‘14158586273’;
3. Next, you have to initialize CURL by using this line:
$ch = curl_init(‘http://apilayer.net/api/validate?access_key=’.$access_key.’&number=’.$phone_number.”);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
4. Then you have to store the data and close the CURL session.
$json = curl_exec($ch);
curl_close($ch);
5. Now, you have to decode JSON response.
$validationResult = json_decode($json, true);
6. Finally, you can get access and use your preferred validation result objects, including validity, country code, and carrier, by using these lines:
$validationResult[‘valid’];
$validationResult[‘country_code’];
$validationResult[‘carrier’];
Overall, the code look like this:
// set API Access Key
$access_key = ‘YOUR_ACCESS_KEY’;
// set phone number
$phone_number = ‘14158586273’;
// Initialize CURL:
$ch = curl_init(‘http://apilayer.net/api/validate?access_key=’.$access_key.’&number=’.$phone_number.”);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Store the data:
$json = curl_exec($ch);
curl_close($ch);
// Decode JSON response:
$validationResult = json_decode($json, true);
// Access and use your preferred validation result objects
$validationResult[‘valid’];
$validationResult[‘country_code’];
$validationResult[‘carrier’];
How can I integrate Numverify into my JavaScript web application?
1. First, you have to set your access key and specify the phone number that you want to verify.
var access_key = ‘YOUR_ACCESS_KEY’;
var phone_number = ‘14158586273’;
2. Now, you can verify the phone number via AJAX call.
$.ajax({
url: ‘http://apilayer.net/api/validate?access_key=’ + access_key + ‘&number=’ + phone_number,
dataType: ‘jsonp’,
success: function(json) {
3. You can get access to the validation result objects by using these lines:
console.log(json.valid);
console.log(json.country_code);
console.log(json.carrier);
}
});
Overall, the code look like this:
// set endpoint and your access key
var access_key = ‘YOUR_ACCESS_KEY’;
var phone_number = ‘14158586273’;
// verify phone number via AJAX call
$.ajax({
url: ‘http://apilayer.net/api/validate?access_key=’ + access_key + ‘&number=’ + phone_number,
dataType: ‘jsonp’,
success: function(json) {
// Access and use your preferred validation result objects
console.log(json.valid);
console.log(json.country_code);
console.log(json.carrier);
}
});
What kind of information do I get from Numverify?
Numverify provides you with several key pieces of information, including location, carrier name, line type.
Let’s try making a basic API request and analyze the data Numverify provides.
http://apilayer.net/api/validate
? access_key = YOUR_ACCESS_KEY
& number = 14158586273
Afterwards, Numverify provides this response in lightweight JSON format:
{
“valid”: true,
“number”: “14158586273”,
“local_format”: “4158586273”,
“international_format”: “+14158586273”,
“country_prefix”: “+1”,
“country_code”: “US”,
“country_name”: “United States of America”,
“location”: “Novato”,
“carrier”: “AT&T Mobility LLC”,
“line_type”: “mobile”
}
As you can see, the valid field is set to true. That means that the given number is valid. Also, you are seeing several key information, including location, country code, carrier, and line type. Besides, the API provides you with local and international formats of the given phone number.
