Issue: Customers in Guernsey, Isle of Man, and Jersey received “No shipping could be found for your address” at checkout, despite being added to the UK shipping zone and products having weights. A valid Isle of Man address (IM2 5EE) was provided; UK mainland checkout worked.
Key clarification: Shopify’s Markets (Settings > Markets) control which regions can check out. If a region isn’t included in an active market, checkout is blocked—even if shipping zones are set.
Action taken: The regions were added to Shopify Markets, which resolved the checkout problem.
Outcome: Resolved. The essential fix was enabling Guernsey, Isle of Man, and Jersey in Markets, not just in Shipping zones.
Notes: An image of the shipping setup was shared but wasn’t central to the solution. No code or attachments impacted the resolution.
