Change WooCommerce SKU text to another label

You can change WooCommerce SKU text to another label using the gettext filter

add_filter('gettext', 'translate_woocommerce', 10, 3);
 * Change SKU Label
 * @link
 * @since 1.0.0

function translate_woocommerce($translation, $text, $domain) {
   if ($domain == 'woocommerce') {
        switch ($text) {
            case 'SKU':
                $translation = 'Catalogue No:';
            case 'SKU:':
                $translation = 'Catalogue No:';
    return $translation;

So in the above snippet which goes in your functions.php file, any instance of ‘SKU’ or ‘SKU:” will get changed to “Catalogue No:”, change the translation text to suit.

    Your snippet above is missing the last part:

    add_filter('gettext', 'translate_woocommerce', 10, 3);

    Then it works

    This is great! Is there a way that you know of to change the text that displays before a variable product option is chosen? Right now before my customers choose an option they see N/A. I would like to change that to “Select option”
