A customer sees your message and can't continue until the address is fixed.
- Make sure customers enter a house number, an apartment number or a valid postcode.
- Refuse P.O. Box addresses for carriers that can’t deliver to them.
- Require customs or tax IDs for countries that need them.
- Block orders that match your own conditions, such as a cart value, a product, a customer tag or a delivery method.
- Give each checkout profile its own favicon (Shopify Plus).
How it works
1
Create a rule
Pick one of the ready-made preset rules, or build your own with the custom rule builder.
2
Test it safely
Set the rule to Testing. It only runs for checkouts that use the test email, so real customers are not affected.
3
Go live
Switch the rule to Active. From then on, every checkout that breaks the rule is stopped and shows your message.

Preset rules
Ten ready-made rules for common address and compliance checks.
Custom rules
Combine conditions on the cart, the customer and the address to block exactly what you need.
Checkout favicon
Upload a different favicon for each checkout profile.
Checkout validation works on every Shopify plan. Only the Checkout favicon feature needs Shopify Plus.
