What Shopify Plus address validation checks, how it differs from autocomplete, and how to add it to checkout to cut returned packages and carrier correction fees.
Shopify address autocomplete isn’t rooftop-level validation. See why confirming the house number and apartment helps packages arrive and cuts carrier correction fees.
Address validation and autocomplete serve different purposes.
Autocomplete helps a customer enter an address. Checkout address validation checks the shipping address that has been entered and can identify a suggested correction or a missing detail.
Addrexx’s current offering focuses on checkout address validation for Shopify Plus. When Addrexx presents a correction, the customer can review it. Accepting the suggestion updates the shipping address in Shopify.
What to check in your store
Does the suggestion explain the proposed correction clearly?
After a customer accepts it, does the shipping address show the accepted correction?
Have you tested the checkout paths your store uses?
Use your configured rules and supported address examples to evaluate the complete flow, rather than judging validation from a single address-entry field.
Guide 02 · Missing apartment details
Give customers a chance to add a missing unit.
A street address can still need an apartment, suite, or unit. For U.S. addresses, Addrexx can flag when secondary address information may be required and prompt the customer to add it.
A focused test checklist
Enable the relevant missing-secondary-address rule.
Use a supported U.S. test address where a unit is expected.
Check that the prompt appears and is understandable.
Add the missing detail and inspect the resulting Shopify shipping address.
Test an address that does not need a unit, too.
Missing apartment detection is a U.S. address feature. Other rules may support U.S. and international addresses differently; configure those rules separately where appropriate.
Guide 03 · Shop Pay
Test saved addresses as well as the first address.
Shop Pay can start with a saved shipping address. With the Addrexx app block enabled in Shop Pay, Addrexx validates the default address on page load and checks the shipping address when a customer selects another saved address.
Before you finish testing
Confirm the Addrexx app block is enabled in Shop Pay.
Test the initial saved-address flow.
Switch to another saved shipping address and check the validation response.
Accept a suggested correction and inspect the updated shipping address.
Repeat relevant tests after changing your checkout or validation rules.
Test your regular Shopify Plus checkout separately so both paths receive attention.
