Wrong or invalid phone numbers at checkout lead to failed deliveries, COD issues, and lost customers — especially for Indian WooCommerce stores.
This WooCommerce Indian Mobile Number Validation snippet enforces a clean +91-prefixed, 10-digit mobile number directly on the checkout page. It restricts non-numeric input, validates the number before order placement, and always saves the phone number in the correct +91 format. The input field is styled natively, mobile-friendly, and works with most themes without conflicts.
Built using WooCommerce hooks, CSS, and lightweight JavaScript — no plugins, no bloat, no performance impact.
Fewer errors. Cleaner data. Better deliveries.
