Allow Cash on Delivery only in certain postcodes

Hi @chirag, you can put below code into your them functions.php:

function postcode_cash_on_delivery( $available_gateways ) {
  global $woocommerce;

  //example: allow COD in United States (US) and certain postcodes
  $cod_country = 'US';
  $cod_postcodes = array("02115", "02116", "10001", "10002");

  if ( isset( $available_gateways['cod'] ) && $woocommerce->customer->get_country() == $cod_county && !in_array($woocommerce->customer->get_postcode(), $cod_postcodes)) {
    unset(  $available_gateways['cod'] );
  }

  return $available_gateways;
}

add_filter( 'woocommerce_available_payment_gateways', 'postcode_cash_on_delivery' );

Thanks Terry that works.
However, in my case I have more than 3000 postcodes that allow cash on delivery.
When put into the array within functions.php, the checkout is becoming a bit slow.

Is there any alternative to this approach?

Hi, after login to WordPress Admin, you can mouseover Appearance sidebar menu, then click ‘Editor’ link, then on your right sidebar, open functions.php file and put those at the end of file and before symbol ‘?>’.
