Shipping Cost by Zip Code — Advanced Postal Code Based Shipping Fees for PrestaShop

Managing shipping costs accurately is one of the biggest challenges for online merchants. By default, PrestaShop only allows you to set shipping fees by zone and country, which is often too broad. A delivery to a remote mountain village should not cost the same as a delivery to a major city center — even within the same country.

The Shipping Cost by Zip Code module solves this problem by giving you full control over your shipping rates based on postal codes. Create custom delivery zones by zip code, assign specific shipping fees per carrier, and let the module calculate the right amount at checkout.

How Does It Work?

First, you choose the managed carriers, for example your express carrier and your local courier. Then you create postal shipping zones: each zone groups zip codes, postal code ranges or prefixes, with its own shipping rates per carrier.

When a customer enters their delivery address, the module finds the zone of their postal code and calculates the shipping cost of each managed carrier. PrestaShop then adds the carrier tax, converts the currency and rounds the price as it does for its own rates. Store pickup, free carriers and carriers of other modules keep their usual prices.

Key Features

Unlimited Delivery Zones by Postal Code

Create as many shipping zones as you need. Split a country into regions, counties, cities or any custom area. Each zone is defined by exact postal codes, numeric ranges (e.g. 75001 to 75020 for Paris, 97100 to 97490 for French overseas territories) or prefixes (e.g. SW1* in London, 20* for Corsica). Codes with dashes, spaces or letters are recognized, such as 00-950 in Poland. Enter several codes at once and check for duplicates before adding them.

Flexible Shipping Rate Configuration

For each zone, configure shipping fees per carrier, or one grid shared by all managed carriers:

• Weight-based calculation — set rates based on the package weight (e.g. 0–5 kg = €5.90, 5–10 kg = €8.50)
• Cart amount calculation — set rates based on the order total (e.g. €0–50 = €6.00, €50–100 = €3.00)
• Percentage-based fees — charge a percentage of the cart total instead of a flat rate (e.g. 3% of the order amount)
• Surcharge on the carrier price — add an amount or a percentage to the PrestaShop rate (e.g. +€8 for islands)
• Unlimited brackets — create as many brackets as you need; the last one can stay open-ended
• Grid copy — copy a carrier's rates to other zones or other carriers, with a price change entered as +5, -2 or 4.90; an invalid value is flagged instead of being ignored

Enter your prices tax excluded or tax included, as you prefer: PrestaShop applies the carrier tax, the customer's currency and the shop rounding.

Free Shipping Options

Offer free shipping for specific zones, specific carriers, or automatically when the cart amount exceeds a set threshold. The delivery checker shows this threshold to the customer and displays "Free" when PrestaShop free shipping will apply at checkout. PrestaShop global free shipping (by amount or weight) and your cart rules keep applying; a refused zone or carrier stays refused.

Disable Delivery for Specific Areas

Need to block delivery to certain postal codes? Enable "Refuse delivery" on a zone: the carriers managed by the module no longer appear at checkout for customers in that zone, and store pickup is still offered. These refusals remain in force even when PrestaShop global free shipping is reached. You can also refuse a single carrier in a zone or set a minimum order amount for it, for example a courier available from €30. A translated message explains the situation to the customer. Ideal for restricted delivery areas, remote locations or regions you do not ship to.

Zone Priority System

If a postal code belongs to several zones (e.g. a general "Mainland France" zone and a more specific "Paris" zone), the module uses a priority system. An exact code wins over a prefix, and a prefix over a range; between two rules of the same type, the zone placed higher in the list wins. The list flags codes handled by another zone, uncovered brackets and zones without rates.

CSV Import & Export

Managing hundreds of postal codes? Use the CSV import to create zones, postal codes and shipping rates in bulk. A sample CSV file is provided. Before importing, a preview counts zones and rates and flags every line in error; you then choose to merge or replace, and an automatic backup of the configuration is saved. The export holds each zone's identifier as well as its name and message in every shop language: "Replace all zones" or restoring a backup recreates the zones exactly. Two zones with the same name are no longer merged, duplicating a zone gives it a unique name ("Paris (copy 2)") and the preview reports an ambiguous name. An export containing rates of a deleted carrier imports with a warning, and files of versions 1.0.0 and 2.0.0 remain readable.

Postal Code Tester

Enter a country, a postal code, a weight and a cart amount: the tester shows the zone found, the rule that selected it and the price tax excluded and included of each managed carrier. It also explains why a carrier is missing at checkout, for example a PrestaShop zone that is not enabled for that carrier, and displays "Free" when a carrier will be free thanks to PrestaShop free shipping.

Multilingual and Multistore

Zone names and customer messages can be translated into each shop language, and the module interface, license panel included, is available in English, French, Spanish, Italian and Polish. In multistore, zones, postal codes and rates are saved for the shop selected at the top of the back office.

Seamless Checkout Experience

At checkout, your customers simply see the carriers available for their address, with the right price. Even before ordering, a delivery checker on the product page and an estimate in the cart show them the carriers and prices for their postal code, the free shipping threshold and, when needed, the zone message. The checker loads after the page is displayed; you enable it separately on product pages and in the cart.

Easy Back-Office Management

The module integrates into your PrestaShop back office under the Shipping menu, with a dedicated "Shipping by postal code" tab:

• Zone list — see your zones with their number of postal codes and rates, delivery allowed or refused, coverage checks and a priority you set by drag and drop
• Zone editor — one page for the zone settings, its postal codes and the rates of each carrier, editable in place
• Tester and CSV import/export — check a postal code and import your files with a detailed preview
• Configuration — managed carriers, prices tax excluded or included, behavior outside zones, customer message, checker and data retention

Technical Details

• Module type: CarrierModule — the module prices the carriers you choose through PrestaShop's official mechanism, which then applies tax, currency and rounding
• No core overrides — the module does not modify any native PrestaShop file; the original carrier settings are restored when you remove them
• Lightweight — one zone lookup per address, reused while the page loads
• Carrier safety — uses the carrier reference (id_reference) instead of id_carrier, so your configuration survives carrier updates
• Postal codes in every format — digits, dashes, spaces and letters; numeric ranges, and prefixes for alphanumeric codes
• Fallback behavior — configurable: when no zone matches, use standard PrestaShop fees or refuse delivery in the countries covered by your zones
• Data kept — zones and rates are kept when you uninstall the module, unless you ask for their deletion
• License — if the license server is temporarily unreachable, the license stays active for seven days from the first failure; a real revocation, suspension or expiry still applies. Without an active license, your shipping fees keep being applied at checkout; only configuration changes are locked
• File access — on PrestaShop 1.7.8 and 8, the CSV export, sample file and backups can only be downloaded by employees allowed to view the zones page

Common Use Cases

• Different shipping fees for overseas territories — charge higher rates for DOM-TOM (97xxx) while keeping mainland France affordable
• Free delivery in your local area — offer free shipping for postal codes near your warehouse
• Block delivery to remote areas — refuse shipping to mountain regions or islands where carriers charge premium rates, while keeping store pickup
• Tiered pricing by region — charge less for nearby cities and more for distant regions, all within the same country
• Percentage-based shipping for high-value orders — charge 2% of cart total instead of flat rates for premium zones
• Local courier with a minimum order — offer a city-center courier from a cart amount you choose

Compatibility

Compatible with PrestaShop 1.7.8, 8.0+ and 9.0+, with PHP 7.4 or later. PrestaShop 1.7.7 is not supported. A managed carrier must be enabled for the PrestaShop zone of the delivery country and have at least one price range for that zone; the tester flags what is missing.

Support is provided from your WePresta customer area or by email at mail@wepresta.shop, according to the support option of your plan. Read the full documentation
