Post code format

There’s no setting for that out of the box and would require one of the following:

• Using a custom coding
• Using https://woocommerce.com/products/postcodeaddress-validation/ to verify the address beforehand
• Using https://www.woocommerce.com/products/woocommerce-checkout-field-editor/ to add a custom postcode field – not sure if this is an ideal solution as most shipping plugins will be looking for the field as powered by WooCommerce itself.

Sorry about the delay. The thing is that we are using Klarna payment gateway which changes the customers post code while in their payment process, before its put back to database. So basically if they refuse to fix their plugin behaviour, I need to find a way to cron or some other way to run through the post codes from orders and add space.
