Postcode Delivery Zones for WooCommerce — delivery zones by postcode, minimum order and delivery windows

Postcode Delivery Zones for WooCommerce is a plugin for stores that deliver themselves: groceries, flowers, bakeries, furniture, catering. You don’t deliver “nationwide” — you deliver to a list of postcodes, with a minimum order that depends on distance, on certain days and at certain hours. WooCommerce shipping zones can calculate a price, but they won’t tell a customer on the product page whether you deliver to them at all, and they won’t stop a €9 order going somewhere with a €40 minimum. This plugin covers exactly that.

The core version is free. Up to three zones with their own postcodes and minimum order, a “Do we deliver to you?” check on the product page and in the cart, and blocking orders to postcodes outside your zones — no license and no time limit. Pro adds unlimited zones, delivery windows with date and time, an order limit per slot and CSV import and export of postcodes.

What the customer sees

If the postcode is outside every zone, no order is created and the customer sees your text (“Sorry, we don’t deliver to 99999 yet”). You can pick a softer mode instead: the message is shown, but the order can still be placed. The minimum order always applies — a minimum you can get around isn’t a minimum. Local pickup is never blocked by a zone: customers who collect can check out with any postcode.

What the admin gets

• Zone countries — for when you deliver to several countries with the same postcode format (Austria and Switzerland both use four digits). The widget then shows a country selector.
• The minimum order is calculated from products after coupons, with or without tax (a setting). Shipping is not included: it isn’t known in the cart yet, and a minimum that “jumps” between pages confuses people.
• Shortcode [postcode_delivery_check] — the same widget on any page: the home page, the footer, your Delivery page.

How it works, step by step

1. You create a zone: “Centre”, postcodes 10115, 101*, 10200…10249, minimum €30.
2. A customer enters 10115 on the product page — “Yes, we deliver. The minimum order for your area is €30”.
3. They add €10 of products and go to the cart — the block suggests: “add €20 more”.
4. At checkout they enter an address with that postcode. While the cart is below €30 the order won’t go through in either the classic or the block checkout — the check runs on the server and can’t be bypassed by turning JavaScript off.
5. Pro: the customer picks “Tue, 22 September, 09:00–13:00”. If the slot is limited to 5 orders, the sixth customer won’t see it. A cancelled order frees its place in the slot.
6. Postcode 99999 is outside the zones — the customer sees your text already on the product page, not after filling in the whole form.

Under the hood

• One check for everything. The product page widget, the cart and the checkout all ask the same function, so the widget never promises what the checkout later rejects.
• A server-side gate in both checkouts: woocommerce_after_checkout_validation for the classic one and woocommerce_checkout_validate_order_before_payment for the block one.
• Windows in the block checkout: the Store API cart response carries the slot list for the customer’s address, and the field shows only those. A foreign slot injected around the page is rejected by the server with an explanation.
• The store time zone (Settings → General), not the server’s: “order by 14:00 — delivered tomorrow” is calculated correctly.
• A Pro gate that doesn’t brick anything: when the trial ends, only Pro features stop. Zones beyond three and windows stay saved and come back as soon as Pro is on again.
