Order holds
Pause fulfillment when an address is invalid or needs review, before the label is bought.

Why AddressVerify
Keep more orders deliverable without taxing checkout
AddressVerify checks once in checkout and again after purchase, then charges $0.02 for that unique Shopify order. You pick the action. Checkout stays fast unless you choose otherwise.

One charge, even if you check twice
Checkout and post-checkout on the same order are one billable event. The Shopify Order ID is the key. Admin Test Address and provider outages are not billed.
A second chance after the order
Thank You and Order Status can suggest a fix, auto-correct, tag, or hold fulfillment after the customer already bought — without sending them back through checkout.
Your rules, not one blunt policy
Allow, Warn, Fix, Block, or Review for house numbers, PO Boxes, city and postal mismatches, and more. Start with Lite checks or turn on Full.
Fail open unless you close it
If a provider is down, AddressVerify fails over, then uses the built-in engine. Checkout is not blocked unless you turn on Fail closed.
No theme files to edit
Add the AddressVerify block in the Shopify checkout editor. Typical setup is about 15 minutes: Thank You, Order Status, optional Checkout, then save.
Fulfillment tools are included
Tag by error type, hold an order before the label is bought, send Klaviyo events, and watch errors, fixes, and estimated savings in the dashboard.
Typical address apps
- A monthly plan before you see value
- Usually one check, only in checkout
- The same action for every error type
AddressVerify
- $0.02 once per unique Shopify order
- Checkout, Thank You, and Order Status
- Allow, Warn, Fix, Block, or Review per check
A Shopify address validator for real fulfillment work
Incorrect shipping addresses cause failed deliveries, carrier fees, and repeat tickets. AddressVerify checks street, house number, city, province, postal code, country, PO Boxes, and common typos before the order is fulfilled. Usage billing is $0.02 once per unique Shopify order. Test addresses and provider outages are not billed.
