How does it work?

The phone verification service performs 3 checks when a phone number is sent to be validated.

Range checks

Checks number length and range to identify the phones country of connection and line type.

Connection checks

Verifies if the phone number is active by performing a flash-call. This makes sure that the phone number is real and accepts incoming calls and texts.

Rules checks

Verifies if the phone number matches your filter settings. For example, only allowing landlines.

Installation

This is the simplest way to add phone verification to your website. It only takes a few minutes.

Copy the code snippet below and update the phoneSelector and licenceKey with your values, then add it within the <body> tags in your webpage page - ideally just before the closing </body> tag.

<script> (function (d) { var conf = { phoneSelector: "#phone_number", licenceKey: "YOUR_ADDRESSFINDER_KEY", defaultCountryCode: "NZ", rules: {}, }; d.addEventListener("DOMContentLoaded", function () {if (d.querySelector(conf.phoneSelector)) {var e=d.createElement("script");e.src="https://api.addressfinder.io/assets/phone/v2/widget.js",e.async =!0,e.onload=function(){new AddressfinderPhone.Phone.Widget(conf.phoneSelector,conf.licenceKey,conf)},d.body.appendChild(e)}}); })(document); </script>

Once the snippet is added, phone verification will automatically start working with your form fields. You can further customise the verification service by adding rules.
