3 Best Shopify Address Validator Apps in 2023

In 2023 customer satisfaction is as important as ever. Customers unhappy with shipping aren’t as likely to return to an online store as 98.1% of consumers say that shipping impacts brand loyalty.

When shopping online, customers make mistakes when completing addresses at checkout. One of the solutions is to have a Shopify address validator, as this will boost customer satisfaction and prevent any losses.

Read on to find out the top three address validation apps and find the right shipping address validator that works best for your Shopify store.

What are Address Validation Apps?

A shipping address validation app prompts customers to fix shipping address typos or mistakes before an order is fulfilled. These apps allow for corrections to be made during the checkout phase reducing the frequency of failed deliveries and, ultimately, your business profits.

Mistakes happen, and the input of incorrect addresses isn't a new occurrence for most businesses. With the right shipping address validator, you can notify customers of any inaccurate addresses to ensure secure delivery to their correct shipping address.

The Benefits of Using a Shipping Address Validator

Shopify address validator apps do more than just flag up incorrect addresses, they provide your online store with other benefits, such as

  • Increase customer satisfaction: by allowing an invalid address to be corrected, the customer will receive their order and will avoid any redelivery fees.
  • Improved communication with customers: by prompting for any address problems, you'll avoid having upset customers as you've reached out to them and shown them that you care about making sure their order is fulfilled.
  • Improved data quality: a deployed shipping address validator is a great tool for ensuring data is accurate so you can send communications and packages to the correct address.
  • Saves time: when a package is sent to the wrong place, it can take some time to track it down. Usually, customers spend a lot of their time trying to get the parcel back to them, and more often than not, it costs an extra delivery fee. An app prevents the issue from getting this far, saving everyone time and effort.


These are just some of the top benefits of address validation apps. Each app will come with its own unique features.Before we tell you which apps made it into our top three, we want to tell you the criteria used in our recommendation.
