Address Validation Helper

About this block

Address Validation Helper shows the typed address beside the postal database suggestion with the differences bolded, and makes keep mine a first class button rather than a buried link, the lede concedes you know your address better than the database does. The footer sizes the stakes honestly, couriers deliver to both spellings, the check exists for real typos.

Two cards, suggested gets the filled button and the emphasized border. Forcing database spellings on people who live at the address is the classic validation failure this block avoids.

When to use

Reach for this block between address entry and payment when your validation API returns a near match. Skip it entirely on exact matches, the interruption must earn its place.

A natural flow around it on an Ecommerce Pro page:

Before

• Address step

After

• Payment step

What you can display

• Missing unit number. The apartment case where the database catches a real gap.
• Undeliverable flag. The carrier cannot reach this address state with alternatives.

Tip: bold only the differences, making people diff two address blocks by eye is the failure mode this block exists to fix.
