Common questions

What is Shopify address validation?

It checks that a shipping address is complete and in the right shape. AddressPill is conversion-safe: the customer is asked to correct the address only after they have bought, and the Shopify order is updated. Shopify address validation and verification explains the difference between a format check and a real address.

Does AddressPill use Royal Mail?

Yes. UK orders are verified with Royal Mail after checkout, then the customer can correct the address. UK address validation covers postcodes, flats, and house names.

What about Australian and Canadian addresses?

Australia needs a unit, suburb, state, and a 4-digit postcode. Canada needs a postal code like K1A 0B1. See Australian address validation and Canadian address validation.
