# Example: Display an existing number

We initialise the plugin on an input which already contains a full international number. The plugin will automatically select the relevant flag, and re-format the number to national format.

## Markup

    <input id="phone" type="tel" value="+447733312345">

## Code

    var input = document.querySelector("#phone");
    window.intlTelInput(input, {
      utilsScript: "../../build/js/utils.js?1638200991544" // just for formatting/placeholders etc
    });
