Phone Validator with Flags for WooCommerce

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.
