Copy and paste the below hook in functions.php (located in theme directory)

add_filter( 'woocommerce_states', 'custom_woocommerce_states' );
function custom_woocommerce_states( $states ) {
$states['XX'] = array(
'XX1' => 'State 1',
'XX2' => 'State 2'

add_filter('woocommerce_cart_calculate_fees1' , 'add_discount',10,1);
add_filter( 'woocommerce_states', 'custom_woocommerce_states' );
function custom_woocommerce_states( $states ) {

return $states;
