The job it handles
Answer serviceability before the shopper reaches checkout.
Zipprover places an availability check beside the product decision. Merchants control the location rules, product scope, storefront presentation, and the message shown for supported or unsupported codes.
Allow and block rules
Enter codes directly or import a CSV, including trailing wildcards for broader ranges.
Selected product scope
Apply a rule to all products or, where the plan supports it, selected products and collections.
Configurable responses
Show static or calculated delivery timing, COD, returns, custom messages, or waitlist capture where available.

Fit and boundaries
Best suited to merchants that can express availability as product and location rules.
Zipprover checks storefront eligibility from the rules you maintain. It is useful for communicating service areas before add to cart, not for calculating or changing Shopify shipping rates.
Important before installing
- Zipprover does not guarantee that an order will be delivered to a validated code.
- It controls storefront add-to-cart behavior; it does not hide or modify Shopify shipping methods at checkout.
- Product, collection, restriction, calculated ETA, and waitlist features vary by App Store plan.

Questions, answered
Zipprover FAQ
Which location formats can Zipprover check?
Zipprover supports ZIP codes, postal codes, postcodes, and pincodes, including alphanumeric values. A trailing wildcard such as 600* or SW1V* can match a broader range.
How do I make the checker appear after installation?
Create and save at least one rule, then enable the Zipprover app embed in your published theme. The app dashboard links to the relevant Theme Editor area.
Can I use a popup or an embedded form?
Yes. Design Settings lets you choose a popup or an embedded product-page form. The embedded form can appear above or below add to cart; a custom placement can require support.
Can rules apply only to selected products?
Yes, on plans that include product and collection rules. Specific-product rules take priority over collection rules, and collection rules take priority over an all-products rule.
Can I upload postal codes in bulk?
Yes. Upload a CSV or enter comma-separated codes directly. You can edit the imported list later without recreating the rule.
Can Zipprover block add to cart?
On eligible plans, Restrict + Information mode can block add to cart for an unsupported code. This does not hide or change Shopify shipping methods at checkout.
What messages can the checker show?
A rule can show static or calculated delivery timing plus COD, returns, or custom messages. Waitlist capture and some message types depend on the selected plan.
Can I change the location wording and design?
Yes. You can change labels, placeholders, button text, availability messages, colors, icons, and custom CSS from Design Settings.
Why is the widget missing or in the wrong place?
Check the app embed, rule status, product selection, and saved codes first. Custom themes and non-standard product forms can require a placement adjustment from ShopSappers support.
