UK Postcode Guide
Shipping to and between Great Britain, Northern Ireland, and the surrounding sovereign islands poses a unique challenge for shipping rate providers. While Shopify does a good job at breaking down UK postcode areas, they do not address more granular and commonly used outward codes. That’s what we’re here for!
The UK Postcode map
In order to tame complex UK Shipping configurations, we’ve provided a mapping tool to visualize exactly where your current price restrictions apply. Any time you have a UK-specific restriction selected a globe icon will appear on the right of the input box. Click the globe icon to open the mapping tool.

UK Specific Restrictions
To help define UK shipping areas intuitively, we provide two restrictions on Prices:
UK Postcode Area (is/is not)
This restriction will allow you to define (or restrict) a price that applies to a broad geographic area of the UK such as BT for Northern Ireland or DG for Dumfries and Galloway.
Below is an example restriction that defines this price rule is only for the BT area:
Here is the same restriction viewed via our shipping area picker:

UK Postcode Outward code (is/is not)
With this restriction, you have more granular control over where the corresponding price applies by providing the postcode area, district, and subdistrict. This block of information in a UK postcode is more commonly referred to as the outward code - hence the name!
Below is an example restriction that includes several sections of the DG area:

Where are Northern Ireland Outward codes?
Isle of Man?
You may notice while BT and IM are shown on our map as valid UK Postcode Areas, they do not appear on our outward code picker. Unfortunately, the Open Map data we have does not specify Northern Ireland or Isle of Man with the same granularity it does mainland UK.
However, we assure you that any outward codes you enter into our UK Postcode Outward Code is / is not restriction will filter shipping addresses as expected. Though this is a shortcoming of our map display, the system we built to compare shipping addresses with your destination restrictions works as expected.
How do I define mainland UK?
You may notice when you select postcode areas for Truro or Portsmouth, our map will automatically highlight several islands and additional areas. Though this is technically correct - these islands are part of their corresponding postcode area - we recognize shipping can be drastically different when parcels must travel over water.
The easiest workaround to provide mainland UK shipping is to design each shipping price you want to provide as two. One restricted to the bulk of Mainland UK and the same price again, but restricted to those outward codes that are still on land.
