Goal: prevent customers outside eligible postal codes from viewing or adding certain products to cart; collect postal codes upfront to validate delivery eligibility.
Current setup is insufficient: shipping profiles (Shopify delivery settings by product/zone) don’t stop customers from adding restricted items to cart, prompting a need for pre-check gating.
Suggested solutions:
Easy Zipcode Check & Validate: adds a zipcode/pin/postal validation popup, homepage section, or product-page widget to confirm delivery availability before shopping; demo store available.
ENS Zip Code Validator: product-page validator that disables Add to Cart/Buy It Now if the entered zip isn’t eligible; can be enabled for all products or specific collections; demo store available.
Feedback and issues: the original poster is satisfied with the approach. Another user reports a zip code field character limit that restricts the number of zip codes that can be entered.
Actions/next steps: Shopify staff advises identifying which app is used and contacting the app developer via the app listing or admin for code/limit adjustments; shared a third‑party app support resource.
Latest update: an alternative “Zipcode Check & Validate” app from MageComp is offered, claiming it can extend the limitation. Status remains open.

i have an issue - some of our products can only be delivered to specific postal codes/areas. And even though we state this on the product page people still order the items when they are in different areas.
And even though I can setup different shipping profiles for certain products - the issue remains that customers add the limited delivery items to their cart.
Ideally I dont want them to be able to see or add the products to their cart - or to somehow get their postal code before going to checkout.
Thanks for reaching out and sharing your question!
Within the Shopify App Store, I found the following apps that may fit the description of what you’re looking for.
Easy Zipcode Check & Validate allows you to add zip code/pin code / postal code validation as a popup, homepage section or a widget on your other pages (ex. Product page) that asks buyers to enter their zip code and validate that delivery is available in their region to make sure you have a right audience. Prior to installing, you can view how the app works in this demo store here.
Ens Zip Code Validator displays on the product page only. The Add to Cart and Buy it Now buttons will be disabled if the zip code is entered. This prevents customers from navigating to the checkout or cart page. The validator can be enabled for all products or for any specific collection.

Victoria. The app works great, but the zip code field restrictions the number of characters, which restricts the number of zip codes. Is there a way to hard code this to get past the limit of the text box ?
You may want to get in touch with the app developer to explore this and see if adjusting the code to get past the limit of the text box is possible. You can request support from the app’s developer either from the Apps section of the Shopify admin, or on the app’s listing page on the Shopify App Store. We’ve included steps on how to contact an app developer in our Support For Third-Party Apps resource.
