Wix App · v1.6.0 · Live on the Wix App Market
Postcode & Delivery Checker
A postcode box that answers “do you deliver to me?” on the spot. No search credits, no shop needed, and it is not a map.
- No search credits
- Needs no shop
- Real postcodes
- No badge, ever
The gap it closes
The free tier on this shelf meters the app’s own verb. The only rival with a real free plan sells “Search Credits Per Month”: limited free, 2,500 at $7, 20,000 at $27.99, unlimited at $138.55 a month. A visitor typing a postcode spends a credit — so the busier your week, the sooner your website stops answering the one question it was put there to answer.
Four of the six take no free customers whatsoever — $11.66, $13.99, $6.30 and $13.99 a month — and one of those has two tiers, $13.99 and $25.19, whose six bullets are identical, word for word. You cannot tell from its own price list what the extra $11.20 a month buys.
Five of the six are bolted to a shop. They are filed under stores, they live on a product page, they sync product counts, they add fees at checkout. The only usable review on the whole object is “doesn’t work for booking page”. A plumber, a florist, a takeaway, a nursery and a man with a van do not have a shop, and should not have to build one to say which streets they cover.
And the whole shelf is American. Every one of them is ZIP-shaped — five digits, or a “PIN code”. One carries a one-star review that says, in its entirety, “dosnt do uk”. A British postcode has two parts, a Canadian one alternates letter and digit, a Dutch one is four digits and two letters, and an Irish Eircode is neither.
How it works
Five steps, then it runs itself.
- 01
Drop the box where the question gets asked
Drag it in from Add Elements → App Widgets — under the order button, in the footer, halfway down a service page, as many times as you like. Four arrangements: a panel with the answer beneath, a compact inline line, a bordered card, and a list that simply prints the areas you cover with no box at all.
- 02
Type your round the way you say it
SW11 covers the whole district. SW11 4NX is one address. SW1* is starts-with, and you have to ask for it — SW1 on its own does not catch SW11, because that is a different district, which is exactly the mistake that would otherwise have you promising streets you have never been to. 10001-10099 is a numeric range. Paste the lot in at once.
- 03
Three answers, not two
Yes, no, or ask us — the commonest real answer at the edge of a round, and the one every rival leaves out. Each area carries what it costs, the minimum order, how soon you get there, and a button through to wherever you already take orders. All free text, so “Free over £30, otherwise £3.50” and “£2 a mile after the first five” go in exactly as you would say them.
- 04
An exception is just a row placed higher
The first area that matches wins. So “we cover SW11 except the two streets over the bridge” is a no row sitting above the yes row — no extra concept, no second screen. A live tester in the dashboard shows you exactly which area answers, before a single visitor sees it, and warns you when a rule can never fire.
- 05
It follows your page, and it never brands it
By default it paints no background and takes its colour from the page, so it is legible on a dark site and a light one without anybody choosing. Colours, corner rounding, text size, width and every switch are yours, on the free plan. There is no watermark and no badge on any plan, ever.
How it behaves
The decisions that matter.
-
Answering a visitor is free for ever, on every plan
Including a lapsed one. A customer must never be turned away because the florist’s card expired. The function that decides this has nowhere in its signature to put a plan, and a test reads the file’s own source to keep it that way.
-
There are no search credits, and there cannot be
The areas are handed to the page once when it loads and the answer is worked out there, in the visitor’s own browser. Measured on a published page: six checks in a row cost zero further network requests. There is nothing to meter, and nothing to run out.
-
It needs no shop
No products, no cart, no checkout, no orders, no customer records, nothing to set up first. There is no product field, no order field and no price field that is a number anywhere in the app’s data.
-
It is a postcode box, not a map
No mapping key to set up, nothing billed to you, no coordinates, no tile server and nothing loaded from anybody else. A test greps the whole app to keep it so.
-
It never learns who asked
Nothing is written to a reader’s device — no cookie, no local storage, no session. On Pro, if you switch the report on, it records the district only (SW11 out of SW11 4NX, ten to twenty thousand addresses) and a count. There is no name column, no email column and no network-address column on that collection, so there is nowhere for one to be added by accident.
-
Nothing is ever uploaded, and no email is ever sent
There is no upload path and no mail server in this app, so neither can fail on your busiest morning.
Pricing
Free tier that actually works.
Billed per site through the Wix App Market, monthly or yearly (yearly saves 20%). Every paid plan starts with a 14-day free trial. The free plan is deliberately functional and never expires, so the app can prove itself on a real site before you pay for it.

Documentation & data handling
Everything it touches, stated plainly.
Installing & getting started
- Add Postcode & Delivery Checker to your Wix site from the App Market and approve the permissions listed below.
- Open it from your site dashboard under Apps. It adds the A site widget (custom element) you place yourself, as many times as you like / A dashboard page for your areas, the wording, the settings and the report / Four collections in your own site’s content manager.
- Follow the five steps above. The free tier covers no cap on areas, postcodes, checks or placements — and no search credits, ever. All three answers (yes, no and ask us), every pattern (district, whole code, starts-with and numeric range), the charge, minimum order and how-soon lines, the button through to your own ordering, all four arrangements, every colour and every visitor-facing word. Paste or import your whole round at once. The live tester and the overlap warning. No watermark and no badge, ever., so you can prove it works before paying.

Permissions, and why each one
Read site, business and email details- The single scope the app asks for. It is how the app knows which site is asking and which plan that site is on. The install screen is one line.
What is stored, and where
- Your areas, postcodes and wording are stored in collections inside your own site, visible in your content manager.
- Nothing is ever uploaded to this app: there is no upload path in it at all.
- Nothing is written to a reader’s device — no cookie, no local storage, no session.
- On Pro, and only if you switch it on, an ask records the postcode district (SW11, never SW11 4NX), which area answered, one of four words and a moment. No name, no email, no network address, no reader identifier of any kind.
- It connects to no third party: no mapping key, no geocoder, no courier platform, no payment platform.
- No email is ever sent by this app; there is no mail server in it.
- Uninstalling removes the app’s collections. Nothing else on your site is touched.

Questions people ask.
Does it work if I do not sell anything online?
That is the point. It needs no shop, no products, no cart and no checkout — nothing to set up first. It is a box on a page. Five of the six apps that do this job on the market are bolted to a shop, and the only usable review any of them has is somebody discovering that theirs does not work outside one.
Will it run out of checks?
No, and it cannot. The areas are sent to the page once when it loads and the answer is worked out in the visitor’s own browser, so a check costs nothing and makes no request at all. The one rival on this shelf with a free plan charges by the check, from a limited free allowance up to $138.55 a month for no cap.
Does it handle British, Canadian and Dutch postcodes?
Yes. SW11 4NX, K1A 0B1, 1012 AB, D02 AF30 and 90210 are all read correctly, with or without the space and whatever the capitalisation. And SW1 does not quietly catch SW11 — they are different districts, and an app that confuses them has you promising streets you have never been to.
How do I say “we cover SW11 except two streets”?
Put a no area with those two postcodes above the yes area that covers the district. The first area that matches wins, so the exception is reached first. The dashboard says so above the list, the sample that ships with the app is built that way so you can see it working, and the live tester lets you check any postcode before a visitor does.
Is it a map?
No, deliberately. There is no map, no mapping key for you to set up, nothing billed to you by anybody, and no coordinates anywhere in the app. A postcode box answers the question faster than a map does, and it cannot break when somebody else changes their pricing.
What do you record about my visitors?
Nothing at all, unless you turn the Pro report on — and then it is the district only. SW11 out of SW11 4NX, which covers ten to twenty thousand addresses, plus which area answered and when. No name, no email, no network address, no identifier. The collection has no column that could hold one. Nothing is written to the reader’s own device either.
What happens if I stop paying?
Every area, every postcode and every word stays on your page exactly as it was, and every visitor still gets an answer, for ever. Areas you had set to run on certain days go back to answering every day rather than going quiet. What stops is the extra authoring: a second list, the report, the change record, the spreadsheets and the private notes.
Does it work on Wix Studio?
Yes. It is a custom element, so it runs on Wix Studio, the classic Wix Editor and Wix Harmony — the same app and the same settings panel.
