# 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.

**Who can use it:**

Address Validation at Checkout is only avaliable to Shopify Plus merchants. All other merchants can use it at the Thank You and Order Status pages.

**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.
