Identification research

What’s on the rating plate?

Consumer and business devices; official services vary by product and country.

Automatic decoding is not yet verified.

This page provides researched identification guidance. It does not invent a date or model from an unsupported number.

Spaces and dashes are accepted. Check O/0 and I/1, and keep any leading zeros.

Checks ENERGY STAR model records and searches manuals separately from the serial. Certification records do not establish this unit’s manufacture date.

Known product context (optional)

Choose a system only when it matches the product family and its documentation. A purchase year or a manual’s publication date does not establish a manufacturing date.

Read the label on your product

Where to find the numbers.

Use the label on the main unit, not a separate component, accessory or shipping barcode.

Scope matters

Supported formats
and historical limits.

  • A machine type/model (MTM), serial number and part barcode identify different things.
  • No universal public serial-to-manufacture-date algorithm verified.
  • Warranty and support paths vary between PC, data-center and mobile products.

Reading your result

Lenovo lookup questions

Why does the year code match more than one year?

Some systems reuse letters or only encode the last one or two year digits. Every supported interpretation is retained. A decade supplied from reliable records can narrow the reading; the tool does not automatically pick the newest year.

Does the serial identify my exact model?

Usually the model is a separate plate field. Where published serial ranges actually identify a model, the result shows model candidates and links to their manuals. Overlapping ranges remain ambiguous.

Can I share the result?

After a lookup, the address includes the serial in a fragment beginning with #serial=. Use “Copy share link” to share the serial and selected context. Opening the link runs the same lookup. The fragment is not a query-string result page.
