This isn't a lookup tool with a search box — it's a reference guide. Given a part number pulled off a server, drive caddy, or asset label, match its format to the manufacturer table below, then follow that row to whichever ITAD Tools lookup or outside source actually resolves it. This walks through using the guide, not operating a tool.
Before you start
Open the Parts Identification guide — reading it needs no account. Running one of the lookups it links to is a separate matter: the Dell lookup and the HP PartSurfer alternative are account tools with no free trial, the HP and Lenovo serial lookups allow one free anonymous lookup per browser before asking you to sign in, and the Apple serial decoder needs no account at all, since it decodes entirely on the page.
Identifying a part step by step
- Find the part number on the component label, asset tag, or system firmware/BIOS screen.
- Open the Parts Identification guide and scan the Format & examples column for a pattern that matches what you're holding.
- Follow that row's "How to identify it" link — most formats route to an ITAD Tools lookup; a few point to the manufacturer's own site instead.
- Run the exact part number through wherever it points, and read back the manufacturer, product family, and specifications it returns.
- If nothing in the table matches the format you're holding, or the lookup comes back empty, treat the part as unidentified rather than guessing from a similar-looking number.
What each format resolves to
- Dell service tags — the Dell lookup returns product name and product line (no warranty data).
- Dell OEM part numbers — not covered by our tools; verify the exact number, leading zero included, at dell.com/support.
- HP / HPE spares, options, and assemblies — the HP PartSurfer alternative cross-references option, spare, and assembly numbers, plus an HPE drive matrix of 1,219 drives; the HP serial lookup covers whole devices.
- Lenovo serials — the Lenovo lookup returns specifications plus warranty status and end date.
- Apple serials (pre-2021) — the Apple serial decoder reads manufacture year/week, factory, and model code on the page itself.
- Cisco product IDs and Intel S-spec codes — not covered; the guide links Cisco's and Intel's own documentation instead.
- Drive part numbers — only HPE-carried drives resolve, via the same drive matrix; consumer and laptop drive part numbers aren't covered.
Why "not covered" beats a guess
Similar-looking part numbers are routinely different products, so the guide's rule is accuracy over completeness: if a format isn't in the table, or a lookup can't verify the exact number, it says so instead of returning a near-miss result. Treat "not covered" as an instruction to check the manufacturer's own source directly, not as a dead end — the guide links that source for every format it doesn't resolve itself.
When something looks wrong
- My part number doesn't match any row in the table. Re-check it against the Format & examples column first — a Dell service tag and a Dell OEM part number look similar but route to completely different places, and the same is true for HP's several number types. If it still doesn't match anything, the guide doesn't cover that manufacturer or number type yet.
- The lookup a row points to reports no result. That's the lookup being honest that it can't verify the exact number, not a guarantee the part doesn't exist — double-check the number for typos before concluding it's uncovered.
- I clicked through to a lookup tool and it asked me to sign in. Expected for the Dell lookup and the HP PartSurfer alternative every time, and for the HP and Lenovo serial lookups once you've already used their one free anonymous lookup in this browser — only the Apple serial decoder among the linked tools never asks.
Frequently asked questions
Do I need an account to read the parts identification guide?
No — the guide is a public page at /features/parts-identification; reading it needs no account or sign-in.
Is this an interactive lookup tool?
No — it's a reference table, not a search box. It doesn't take a part number itself; it shows each manufacturer's format and links to whichever ITAD Tools lookup, or outside source, actually resolves that format.
Which part numbers does the guide route to an ITAD Tools lookup, and which to an outside source?
Dell service tags, HP/HPE spares/options/assemblies, Lenovo serials, and pre-2021 Apple serials each route to an ITAD Tools lookup. Dell OEM part numbers, Cisco product IDs, and Intel S-spec codes aren't covered by our tools, so the guide points those at the manufacturer's own site instead — and only HPE-carried drives resolve among drive part numbers; consumer and laptop drive numbers aren't covered either.
Do I need to sign in to use the lookups the guide links to?
For the Dell lookup and the HP PartSurfer alternative, yes — always. The HP and Lenovo serial lookups allow one free anonymous lookup per browser first, then ask you to sign in. The Apple serial decoder is the exception among the linked tools: it decodes entirely on the page and needs no account at all.
Can an AI agent or automated pipeline use this guide?
Yes — that's a stated purpose of the page. It points agents and pipelines at /llms.txt (a platform summary), /llms-full.txt (full tool documentation), the JSON API index at /api/, and a public, no-auth certificate-status endpoint. There's no public parts-lookup API yet; the guide asks anyone needing server-to-server JSON access to email support instead.
