Simplify WooCommerce checkout process: remove state/province field, making it "non-required" for all countries

Question

I found a way on GitHub to remove the state/province field 'state' in woocommerce's checkout page. https://gist.github.com/jeherve/a07ccf469025d722ad7016f6953146fd (Thanks Jeremy Herve!)

function jeherve_remove_state_field( $fields ) {
    unset( $fields['state'] );

    return $fields;
}
add_filter( 'woocommerce_default_address_fields', 'jeherve_remove_state_field' );

My question is: Is it safe to remove the state/province field, or is it already set in woocommerce that certain countries require that field?

Do I need to first set the state/province field for each country to 'optional'?

I'm concerned that by removing the state/province field, the checkout page won't work properly for certain countries because they require that field.

I don't need to set the state/province field to $address_fields['state'][required]=false like I do with the zip code field, right?

add_filter( 'woocommerce_default_address_fields' , 'override_postcode_validation' );
 
function override_postcode_validation( $address_fields ) {
  $address_fields['postcode']['required'] = false;
  return $address_fields;
}

Thank you very much for your help. Thanks.

Answer 1

You can use the same code to remove the state/province field from the checkout form.

function wc_remove_state_field($fields) {

    unset($fields['state']);
    return $fields;
}

add_filter('woocommerce_default_address_fields', 'wc_remove_state_field');

This will not cause any problems with the checkout process. You don't need to set this for all countries.

1 - Postal code still needs to be filled in to continue.

2 - Payment gateways that require a state/province field cannot be used for checkout.
