Fix WooCommerce Pincode Error

Job ID: 40408829

Budget: ₹600 – ₹1,500 INR

My WooCommerce store suddenly rejects every customer’s entry with the message “pin code is not servicable.” It happens on checkout and the product pages alike, no matter which pin code is typed. I did install and update a couple of shipping-related plugins right before the issue surfaced, so I suspect a mis-configuration or conflict rather than a server-side block.

What I need you to do:

• Pinpoint the exact cause—whether it sits in WooCommerce core settings, a shipping-zone rule, the postcode database, or an extension conflict.
• Correct the logic so valid Indian pin codes are accepted again while genuinely out-of-zone areas remain blocked.
• Test at least five sample pin codes from different states to confirm checkout now proceeds to payment without errors.
• Leave me a brief changelog outlining what you touched so I can replicate the fix on staging later.

You’ll get full WP admin, FTP, and cPanel access. No theme edits required unless the template overrides the form validation; otherwise keep code changes limited to a child theme or a custom plugin so future updates stay safe.

If you’re comfortable with WooCommerce shipping zones, postcode tables, and plugin debugging, this should be a quick turnaround job.
