Last updated on October 2, 2022 @ 12:01 am

There are many reasons why you might want to restrict the ZIP code digits in WooCommerce. For example, if you only ship to certain areas, you might want to limit the ZIP code digits to only those that are within your shipping range. Or, if you have a physical store location, you might want to limit the ZIP code digits to only those that are within a certain distance of your store. Whatever the reason, restricting the ZIP code digits in WooCommerce is easy to do.

First, you need to login to your WordPress dashboard and go to WooCommerce > Settings. From there, click on the Shipping tab and then click on the Shipping Zones link. You will see a list of all the shipping zones that you have created.

Find the shipping zone that you want to restrict the ZIP code digits for and click on the Edit link.

On the next page, scroll down to the Shipping Method options and find the Flat Rate shipping method. Click on the Edit link for Flat Rate.

PRO TIP: If you are using the WooCommerce plugin on your WordPress site, you may want to restrict the number of digits that are allowed in the ZIP code field. This can be done by adding the following code to your theme’s functions.php file:

add_filter( ‘woocommerce_checkout_fields’ , ‘restrict_zip_code_digits’ );

function restrict_zip_code_digits( $fields ) {
$fields[‘billing’][‘billing_postcode’][‘maxlength’] = 5;
$fields[‘shipping’][‘shipping_postcode’][‘maxlength’] = 5;
return $fields;
}

On the next page, scroll down to the ‘Restrict postcodes’ option and select ‘Yes’. Enter the ZIP code digits that you want to restrict in the ‘Postcodes’ field. You can enter multiple postcodes by separating them with a comma. Once you are finished, click on the Save changes button.

That’s all there is to it! You have successfully restricted the ZIP code digits for a specific shipping zone in WooCommerce.

Conclusion:
