Shipping zones in Shopify are described as groups of countries or regions, and that is where they stop. There is no native way to say that you deliver to one set of postal codes inside a country and not another, and nothing native tells a shopper on the product page whether their address is one you serve. Checkout knows nothing either until they type it: the address values are documented as undefined until the buyer has entered one.

So the box these apps put on the product page is entirely their own, and so is the data behind it. That is not a criticism, it is the reason the category exists, and it explains why the useful comparison is about the rules rather than the widget: which codes, for which products, with what delivery estimate, and whether cash on delivery is offered there. Cash on delivery is a store-wide payment method in Shopify with no per-area switch, and Shopify's own example of hiding a payment method keys off the country, so any postal-code-level control over it is the app's work.

What to look for in a Cep app

Warn or actually prevent: Most of these tell a shopper that you do not deliver there and then let them buy anyway. Stopping the order needs a validation function at checkout, which is a different mechanism, and only some listings claim it. Decide which you need, because a warning on the product page does not stop the order that arrives at two in the morning.
Where the code list comes from: A checker is only as current as its data. Ask whether you upload the list, whether it is pulled from a courier, how it is updated, and what the widget says for a code it has never seen.
Per product, not just per store: Bulky items, cold chain and restricted goods usually have their own coverage. Rules by product, collection or tag are standard across this category, so treat their absence as disqualifying.
What it promises about timing: Every listing here shows a delivery estimate alongside the check, which turns the widget into a promise. Find out where that number comes from and whether you can adjust it for your own dispatch times before it appears on a thousand product pages.

What does the Built for Shopify badge mean?

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 →
