Why Does an Ecommerce Checkout Lose the Selected Shipping Address?

11/10/2026

A checkout may forget a selected address when a session expires, a customer signs in midway, address validation rejects a field, or a shipping method change triggers a cart refresh. Customers may abandon checkout if they must re-enter details.

What to check

Reproduce the steps as guest and signed-in users. Check session state, address validation messages, saved-address selection, shipping recalculation, browser storage, and recent checkout customizations.

Recommended next step

Correct the state transition or validation behavior and preserve entered fields when safe. Test address edits, sign-in, shipping changes, and checkout refreshes across common devices before releasing changes.
