What this does

AddressPill validates the shipping address while the customer is still in checkout.

​
Why this matters

You catch issues before payment. This reduces bad addresses entering your fulfillment pipeline.

​
What you can control

  • Require house number
  • Check duplicate first/last name
  • Detect special characters in address fields
  • Detect common email typos
  • Block with custom regex pattern
  • Set field length limits for address, name, and company
  • Choose rule behavior: warning or block checkout

​
Where to configure

Open In-checkout settings.
