How to Turn on Address Validation

Getting address validation running takes three simple steps and about 10 minutes. You'll create a verifier to check addresses, install the checkout extension so it appears to customers, and set up pay-as-you-go billing with a spending cap you control.

What you'll need:

• Admin access to Order Editing app

• Admin access to Shopify checkout settings

• Ability to accept Shopify usage charges

Step 1: Accept Usage Charges

1. Click Adjust usage cap

2. Set monthly spending limit (e.g., $250)

3. Accept usage charges in Shopify

What's a usage cap? Maximum monthly charge. Validation pauses when reached—you can increase anytime.
