So, you can keep your database clean with only genuine leads. Also, it allows you to retrieve key information about the phone numbers, including country, carrier, and phone number type.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_should_I_use_a_free_phone_number_lookup\"><\/span><strong>Why should I use a free phone number lookup?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<ul><li>Validate phone numbers to find real clients<\/li><li>Prevent fraudulent activities during sign-up<\/li><li>Know the carrier mix of your leads to accurately predict marketing costs and message deliverability rates<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_can_I_implement_number_lookup_technology_in_my_application\"><\/span><strong>How can I implement number lookup technology in my application?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>You can implement number lookup technology in your web application by using Numverify. It\u2019s a free phone number lookup API. It can validate national and international phone numbers in real-time efficiently.<\/p>\n\n\n\n<p>Numverify enables you to verify the phone number by simply passing it into the API&#8217;s request URL. So, it has made the validation process very simple. Next, let\u2019s take a look at how you can implement the free phone number lookup API into your PHP and JavaScript web applications.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_do_I_do_to_integrate_Numverify_into_my_PHP_web_application\"><\/span><strong>What do I do to integrate Numverify into my PHP web application?&nbsp;<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>1. First, you have to set API Access Key, which you can get for free by\u00a0<a href=\"https:\/\/numverify.com\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">signing up here<\/a>.<\/p>\n\n\n\n<p>$access_key = &#8216;YOUR_ACCESS_KEY&#8217;;<\/p>\n\n\n\n<p>2.

Next, you have to initialize CURL by using this line:<\/p>\n\n\n\n<p>$ch = curl_init(&#8216;http:\/\/apilayer.net\/api\/validate?access_key=&#8217;.$access_key.&#8217;&amp;number=&#8217;.$phone_number.&#8221;);&nbsp;&nbsp;<\/p>\n\n\n\n<p>curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);<\/p>\n\n\n\n<p>4.

Now, you have to decode JSON response.<\/p>\n\n\n\n<p>$validationResult = json_decode($json, true);<\/p>\n\n\n\n<p>6. Finally, you can get access and use your preferred validation result objects, including validity, country code, and carrier, by using these lines:<\/p>\n\n\n\n<p>$validationResult[&#8216;valid&#8217;];<\/p>\n\n\n\n<p>$validationResult[&#8216;country_code&#8217;];<\/p>\n\n\n\n<p>$validationResult[&#8216;carrier&#8217;];<\/p>\n\n\n\n<p>Overall, the code look like this:<\/p>\n\n\n\n<p>\/\/ set API Access Key<\/p>\n\n\n\n<p>$access_key = &#8216;YOUR_ACCESS_KEY&#8217;;<\/p>\n\n\n\n<p>\/\/ set phone number<\/p>\n\n\n\n<p>$phone_number = &#8216;14158586273&#8217;;<\/p>\n\n\n\n<p>\/\/ Initialize CURL:<\/p>\n\n\n\n<p>$ch = curl_init(&#8216;http:\/\/apilayer.net\/api\/validate?access_key=&#8217;.$access_key.&#8217;&amp;number=&#8217;.$phone_number.&#8221;);&nbsp;&nbsp;<\/p>\n\n\n\n<p>curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);<\/p>\n\n\n\n<p>\/\/ Store the data:<\/p>\n\n\n\n<p>$json = curl_exec($ch);<\/p>\n\n\n\n<p>curl_close($ch);<\/p>\n\n\n\n<p>\/\/ Decode JSON response:<\/p>\n\n\n\n<p>$validationResult = json_decode($json, true);<\/p>\n\n\n\n<p>\/\/ Access and use your preferred validation result objects<\/p>\n\n\n\n<p>$validationResult[&#8216;valid&#8217;];<\/p>\n\n\n\n<p>$validationResult[&#8216;country_code&#8217;];<\/p>\n\n\n\n<p>$validationResult[&#8216;carrier&#8217;];<\/p>\n\n\n\n<p><strong>How can I integrate Numverify into my JavaScript web application?&nbsp;<\/strong><\/p>\n\n\n\n<p>1.
