Why Restrict by Country?

For many B2B businesses, regional targeting is critical. Limiting access to a single country allows you to:

• Focus marketing efforts on one demographic.

• Streamline shipping and taxation.

• Avoid unnecessary international inquiries.

• Ensure compliance with local laws and trading standards.

Step-by-Step: How to Set Country Restrictions in B2BKing

Here’s how you can configure B2BKing to accept registrations and interactions only from Australia:

1. Access the B2BKing Dashboard

   Log in to your WordPress admin panel and go to B2BKing > Settings.

2. Navigate to the Registration Settings

   Within the B2BKing settings panel, locate the Registration & Approval section.

3. Enable Country Restrictions

   B2BKing provides a built-in filter where you can restrict available billing or shipping countries.

   Add this code to your functions.php file or a site-specific plugin to allow only Australia:

   
   /* — Countries: AU only — */
   add_filter( ‘woocommerce_countries’, function ( $countries ) {
   return array( ‘AU’ => __( ‘Australia’, ‘woocommerce’ ) );
   }, 10 );

   /* — Store default country — */
   add_filter( ‘woocommerce_default_country’, function () {
   return ‘AU’;
   }, 10 );

   /* — Default address state (global) — */
   add_filter( ‘woocommerce_default_address_fields’, function ( $fields ) {
   if ( isset( $fields[‘state’] ) ) {
   $fields[‘state’][‘default’] = ‘NSW’;
   }
   return $fields;
   }, 10 );

   /* — Checkout defaults + remove label/floating on country field — */
   add_filter( ‘woocommerce_checkout_fields’, function ( $fields ) {
   // Billing defaults
   if ( isset( $fields[‘billing’] ) ) {
   if ( isset( $fields[‘billing’][‘billing_country’] ) ) {
   $fields[‘billing’][‘billing_country’][‘default’] = ‘AU’;
   $fields[‘billing’][‘billing_country’][‘label’] = ”;
   $fields[‘billing’][‘billing_country’][‘placeholder’] = ”;
   if ( ! empty( $fields[‘billing’][‘billing_country’][‘class’] ) && is_array( $fields[‘billing’][‘billing_country’][‘class’] ) ) {
   $fields[‘billing’][‘billing_country’][‘class’] = array_values( array_diff(
   $fields[‘billing’][‘billing_country’][‘class’],
   array( ‘ast-animate-input’ )
   ) );
   }
   }
   if ( isset( $fields[‘billing’][‘billing_state’] ) ) {
   $fields[‘billing’][‘billing_state’][‘default’] = ‘NSW’;
   }
   }
   // Shipping (if enabled)
   if ( isset( $fields[‘shipping’] ) ) {
   if ( isset( $fields[‘shipping’][‘shipping_country’] ) ) {
   $fields[‘shipping’][‘shipping_country’][‘default’] = ‘AU’;
   $fields[‘shipping’][‘shipping_country’][‘label’] = ”;
   $fields[‘shipping’][‘shipping_country’][‘placeholder’] = ”;
   if ( ! empty( $fields[‘shipping’][‘shipping_country’][‘class’] ) && is_array( $fields[‘shipping’][‘shipping_country’][‘class’] ) ) {
   $fields[‘shipping’][‘shipping_country’][‘class’] = array_values( array_diff(
   $fields[‘shipping’][‘shipping_country’][‘class’],
   array( ‘ast-animate-input’ )
   ) );
   }
   }
   if ( isset( $fields[‘shipping’][‘shipping_state’] ) ) {
   $fields[‘shipping’][‘shipping_state’][‘default’] = ‘NSW’;
   }
   }
   return $fields;
   }, 20 );

   /* — CSS/JS failsafe: hide label and disable floating even after AJAX refresh — */
   add_action( ‘wp_footer’, function () {
   if ( ! is_checkout() ) return;
   ?>
   <style id=”wc-au-only-fix”>
   #billing_country_field > label,
   #shipping_country_field > label { display: none !important; }
   #billing_country_field .woocommerce-input-wrapper strong,
   #shipping_country_field .woocommerce-input-wrapper strong {
   display: inline-block !important; margin: 0 0 8px !important; font-weight: 600;
   }
   </style>
   <script>
   (function(){
   function fixCountryRow(id){
   var row = document.getElementById(id);
   if(!row) return;
   row.classList.remove(‘ast-animate-input’);
   var label = row.querySelector(‘:scope > label’);
   if(label){ label.style.display = ‘none’; }
   }
   function run(){ fixCountryRow(‘billing_country_field’); fixCountryRow(‘shipping_country_field’); }
   document.addEventListener(‘DOMContentLoaded’, run);
   window.addEventListener(‘load’, run);
   if (window.jQuery) { jQuery(document.body).on(‘updated_checkout’, run); }
   new MutationObserver(run).observe(document.body, { childList:true, subtree:true });
   })();
   </script>
   <?php
   }, 999 );

4. Optional: Customize Country Dropdown

   If you’re using custom registration forms, you may also want to limit the country options shown to users. This ensures that only eligible businesses from your target country can register.

5. Test the Changes

   Log out and try to register as a new user to ensure that only Australia is selectable or allowed. Make sure all pages behave as expected with the restriction in place.
