Checkout already completes addresses for shoppers in the countries Shopify supports, so this category is not filling an empty space. It splits into two capabilities that sound similar and are gated completely differently. Replacing or extending that autocomplete means a checkout extension, which is restricted to the top plan and needs a separate grant to touch customer data. Refusing a bad address, a PO box where you cannot deliver, a missing house number, a postcode you do not serve, is a validation function, and those run on any plan when they arrive through a public app. Two of the listings say as much on their own pages.

The other thing worth knowing is what happens afterwards. A shipping address on an existing order can be corrected natively, so the case for buying something here is preventing the bad address rather than being able to fix one. That is a narrower promise than the category tends to make, and a more honest way to judge it.

What to look for in a Adress Ninja app

Blocking and completing are different products
One stops an order you cannot fulfil; the other makes typing easier and is plan-restricted. Work out which failure actually costs you money, because for most stores it is the undeliverable parcel rather than the fiddly form, and that half is available regardless of plan.
Write down what counts as bad
PO boxes, missing house numbers, parcel lockers, characters outside your carrier's alphabet and postcodes you refuse are all separate rules, and apps cover different subsets. List the ones that have actually burned you rather than accepting a generic promise of validation.
Blocking at checkout has a cost
Every rule that refuses an address also refuses some legitimate customers. Ask what the shopper sees when they are stopped, and whether you can review what was blocked, because a silent rule tuned slightly wrong loses orders you never learn about.

Built for Shopify
Built for Shopify is the highest level of recognition Shopify awards an app. To earn the badge, an app must meet Shopify's standards for safety, performance, ease of use, and proven usefulness: it cannot slow down the admin, storefront, or checkout, must integrate seamlessly into the Shopify admin, and must demonstrate quality through installs, reviews, and ratings over time. When comparing similar apps, preferring ones with the badge is a safe default. Learn more about the Built for Shopify badge →
