NSN lookup by stock number or part number

Paste what is on your paperwork. A stock number opens its part page, a manufacturer part number shows the stock numbers it is listed under, and anything that does not match goes to the quote desk as you typed it.

Cross-referencesEvery manufacturer part number and CAGE code listed against that stock number.
Next stepAdd it to a list and the quote desk answers availability first, then sends a formal quote.

When one part number points to several stock numbers

Manufacturers sometimes reuse a part number across different items. When that happens the lookup lists each stock number with its item name, so you choose the one that matches your drawing instead of getting the first hit.

A part number listed under a single stock number goes straight to that part page.

No match? Send it as you have it

Old numbers, drawing numbers and partial part numbers can go to the quote desk as written.

Questions about NSN lookup

How do I convert a part number to an NSN?

Type the manufacturer part number into the lookup above. If the federal record lists it under one stock number you land on that part; if it is listed under several, you get the list with item names to pick from.

How do I find an NSN number for a part?

Start from whatever identifier you already hold: the part number on the label, the number on a drawing, or an old stock number from a previous order. The lookup checks part numbers and CAGE codes against the federal record; anything it cannot place, send to the quote desk.

Is there an NSN database I can search without an account?

Yes. This lookup searches the federal item catalogue with no login required. Requesting a quote is the only step that asks for your contact details.

What is the difference between a stock number lookup and a part number lookup?

A stock number identifies one item in the federal supply system; a part number identifies what a manufacturer makes. One stock number often carries several manufacturer part numbers, which is why the result page lists every cross-reference.
