Postcode & ZIP calculator
Turn a postcode or ZIP into a useful shipping answer.
Let shoppers enter their destination and see the Shopify shipping options available before checkout.
The problem
“Delivery varies by location” is not an answer.
A shipping policy can explain the rules, but it cannot tell an individual shopper which configured rate applies to their destination and basket. A quote field turns a broad policy into a practical answer.
With ShipCalc
Support postcode-sensitive delivery worldwide.
Shoppers type only a postcode or ZIP — no state, suburb, or street address. ShipCalc works out the region, asks Shopify for the eligible rates, and shows them in seconds.

Questions
Common questions.
Does ShipCalc set postcode rules?
No. It displays rates from Shopify; it is not a separate rate-rule engine.
Can shoppers choose a country?
Yes. The international country selector helps shoppers request the right destination context.
What if no rate appears?
Check that the destination is included in an active Shopify market and shipping zone, and that the product or cart meets the configured rate conditions.
Show shoppers the shipping cost before they ask.
