Asset Information Lookup System

Compiled 18 Aug 2026

Look up manufacturer device and warranty information by serial number or service tag. Lookups are proxied through a Cloudflare Worker — nothing you search is stored.

Dell information lookup

Enter one or more Dell service tags — one per line, or separated by commas/spaces. Up to 20 at a time.

Apple Lookup, Leave Feedback, and "Information" Instead of "Warranty"

Apple is now a live tab, alongside Dell — looks up AppleCare/warranty coverage via the Apple School/Business Manager API. If more than one Apple org is configured on the server, every one is searched automatically per serial number, and the result shows which org it was found in. Headings and buttons now say "information" rather than "warranty" throughout (e.g. "Look Up Information"), since Apple results carry more than just warranty status. Settings also gained a Leave Feedback mailto link.

1.2

Real Logo, Installable as an App, and a Help Guide

The header logo is now twice the size, and the placeholder crossed-line X inside the shield has been replaced with the real hand-painted X mark. The old click-to-cycle theme button is now a Settings pop-out (the gear icon, top right) holding a proper Theme dropdown, this Release Notes panel, a new step-by-step Help guide, and (on Chrome/Edge) an Install App button. The version badge next to the title now shows a Compiled date alongside it, and opens Release Notes directly when clicked.

1.1

Renamed to Asset Information Lookup System, UK Dates

Renamed from "Warranty Lookup" to Asset Information Lookup System, matching the project name. Dates (ship date, warranty end date, coverage start/end) now display UK-style (DD/MM/YYYY) instead of ISO. The header/favicon shield's checkmark was replaced with a crossed X mark.

Launch

Initial release: Dell warranty lookup (up to 20 service tags at once) via a Cloudflare Worker that proxies Dell's TechDirect API, keeping the OAuth client secret server-side. Lenovo and Apple are stubbed as "Coming soon" manufacturer tabs. Deploys automatically to Cloudflare Workers on every push to main via GitHub Actions.

Help Guide

1. Pick a manufacturer

Use the tabs near the top — Dell and Apple are live. Lenovo is marked "Coming soon" and can't be selected yet.

2. Enter service tags or serial numbers

Type or paste one or more into the box — one per line, or separated by commas or spaces. Up to 20 at a time. Click Look Up Information (or press Ctrl/Cmd + Enter from the box).

For Apple, if more than one Apple School/Business Manager organisation is configured, every one of them is searched automatically — you don't need to know in advance which school or org a device belongs to.

3. Read the results

Each entry gets its own card: model, ship date, a status badge (Active/Expired/Unknown), the warranty end date, and a table of every coverage entry on file with its own start/end dates. An Apple result also shows which org it was found in. An entry with no data on file shows an explanation instead.

Settings

The gear icon (top right) opens Theme (System/Light/Dark), this Help guide, Release Notes, Leave Feedback, and — on browsers that support it (Chrome/Edge) — Install App, which adds a standalone, taskbar/home-screen-pinnable copy. Safari/iOS has no equivalent Install button, but Add to Home Screen from the Share sheet works there instead.

Your data

Nothing you search is stored. Each lookup is proxied through a Cloudflare Worker straight to the manufacturer's own API and back — no database, no logging, no analytics.
