Set Default State Field Value on WooCommerce Checkout Page

In this article, we will see how to set a default State value for the WooCommerce Checkout Page billing and shipping field(s). I saw this question asked in a WooCommerce Facebook group and like always, took the opportunity to research a solution and learn something new.

I’ve included the code for both the Billing and Shipping State fields (in case needed). In this example, I’m setting the State field dropdown selector to ‘LA’ for Louisiana:

add_filter( 'default_checkout_billing_state', 'custom_woo_default_checkout_billing_shipping_state' );

add_filter( 'default_checkout_shipping_state', 'custom_woo_default_checkout_billing_shipping_state' );

function custom_woo_default_checkout_billing_shipping_state()
{
    return 'LA'; //your preferred state abbreviation goes here
}

(Note: The code would need to be altered if for some reason the Shipping and Billing states were not the same.)

Do you need this exact same functionality applied to your own WooCommerce store? Consider hiring me to complete this for you, hassle-free. Visit my services page to learn more.
