Does Address Validation iO also validate orders made via express checkout (e.g. PayPal, Apple Pay, Google Pay)?

Yes! After the order has been made through any express checkout, customers will be redirected to Shopify's order status page. Address Validation iO will show a warning about a wrong address on that page. Additionally, an email notification will be sent to the customer.

Why is address validation done after checkout?

Validation during checkout would only be available for Shopify Plus customers. To make our app accessible to all, validation is done after checkout.

Isn't Google Autocomplete enough?

Unfortunately, enabling Shopify's Google Autocomplete won't validate the address entered. While it helps the customer filling out the form, the result may still be an invalid address (e.g. a missing house number). Address Validation iO complements Google Autocomplete by validating the address.

How reliable is the address validation of Address Validation iO?

As reliable as it gets! Our address pool is fed and constantly updated by multiple sources. Addresses are validated against a world-wide database, spanning over 250 countries and territories. Try us out, you won't be disappointed!

Does the app also react to missing house numbers?

Yes, if a customer forgets entering a house number, the app will also inform him about updating his address.

Does the app also validate orders that are entered manually by the merchant?

The merchant is able to manually validate addresses by simply choosing them from the paid orders. And yes, you can even manually validate multiple orders in bulk.


How does the billing work?

Depending on which plan you’ve chosen, you either have 250, 1500 or 3000 address validation lookups included. Every additional lookup will, again depending on your chosen plan, cost between 0.035$ and 0.040$. The monthly fee plus possibly additional lookups will be charged every month. You can set a limit for the additional usage charge.

What will be charged for?

Every order, even if the address is valid or has been validated before. Hint: The Pro and the Business Plan also allows you to validate billing address. In that case both the validation of the shipping and the billing address will be charged separately.

Will I get charged for correct addresses?

Yes, since the address has to be sent to our data provider for validation.

Do I need a Shopify Plus account to use this app?

No. Our main goal was, to create Address Validation iO in a way every merchant can use it.

Can I test the app first?

Sure, we're offering a 7 day test trial!

What does the trial include?

Within the first 7 days you will have up to 750 address validations for free. The amount depends on your chosen plan: Starter: 250 validations / Business: 500 validations / Pro: 750 validations. Did you reach your free look-ups in less than 7 days, the trial will end. Good work, your store is performing great!


Does the app work with custom Shopify themes?

Yes, the app works in the background and therefore completely independently from the Shopify themes.

Does the app support my language?

Address Validation iO supports every selectable language on Shopify including the corresponding formats e.g. Arabic from right to left.

Which languages are used to communicate with my customer?

Address Validation iO will use the language according to the language selection by the customer in your storefront. This includes the address-validation-page and the notifications.

Do I need a Shopify Plus account to use this app?

No. Our main goal was, to create Address Validation iO in a way every merchant can use it.

Does the app affect my store performance?

No, the app won't affect your store performance at all.

How does Address Validation iO tag my orders after processing?

The following tags will be added by Address Validation iO:

<strong> address validation

How does the update process work?

On Shopify it is usual that updates are made automatically. However, if the consent of the merchant is required, e.g. because access rights change, we will send the merchant an email.

Is it possible to pause automatic validation for certain sales channels?

Yes, you can disable single sales channels in the apps settings.

The banner on the order status page does not load/loads very slowly. What is the reason?

The banner on the order status page may appear delayed due to the store’s performance. The store can be slowed down by the following factors: - Post purchase apps that slow down the order status page - Shopify does not always provide the same server performance which may not be sufficient in some cases
