Phone Validator with Flags for WooCommerce enhances the billing phone field on the checkout page by:

  • Displaying a dropdown with country flags and dial codes.
  • Auto-detecting the default country based on your WooCommerce store location.
  • Validating the phone number format before order submission.
  • Respecting WooCommerce’s “Selling Locations” settings to limit the list of countries.
  • Supporting both Classic Checkout and Block Checkout (introduced in WooCommerce 8+).
  • Allowing full customization via a dedicated settings page under WooCommerce → Settings → Phone Validator.
  • Supporting the shipping phone field independently from the billing phone field.

Ideal for WooCommerce stores targeting international customers who want to ensure clean, valid phone numbers during checkout.
