    add_action('wp_footer', 'postcode_toupper');

function postcode_toupper(){
    echo '<script>jQuery(function($) {$("#billing_postcode").keyup(function() {  this.value = $("#billing_postcode").val().toUpperCase();    });});</script>';
}

    Add this code in your active theme functions.php

    I tend to use CSS text-transform: uppercase;

    For the element id ‘billing_postcode’ use…

    #billing_postcode {text-transform: uppercase;}
