Use this search when you have a stock number and want its identity, technical details, reference parts or buying history. Enter the full 13-digit NSN or its 9-digit NIIN. Keep leading zeros.

Example: find a cap screw

Enter 5305007262550 or its nine-digit NIIN 007262550, then choose Search. Both verified searches identify SCREW,CAP,HEXAGON HEAD; the NIIN search returns full NSN 5305007262550. The item page is titled NSN/NIIN Search Results. Confirm the displayed name before continuing.

You can reach the same item through NSN Opportunities: select the NSN in the opportunity list, then select it again in the solicitation results. Once you reach the item page, its research buttons work with that selected item.

The complete item page below shows the identity, price fields, reference-parts list and research buttons for the same NSN.

Find a number when you know the product instead

From the starting Search by NSN/NIIN screen, Search NSNs by Item Name opens Keyword to NSN Search. Enter SCREW,CAP,HEXAGON HEAD and choose Search. The example returns a paged table of item names and NSNs. Many stock numbers share that name, so the name alone does not identify a particular size or specification. Page-number links below the list show additional matches.

For a guided classification search, choose Search NSNs by FSG from the starting screen:

Select 53 - Hardware and Abrasives and choose Show FSCs.
Select 5305 - Screws and choose Show Term(s).
Select SCREW in the first term list, then Search 1st Term.
Select CAP in the next list, then Search 2nd Term.
Select HEXAGON HEAD in the third list, then Search 3rd Term.
The NIIN list contains matching numbers, including 007262550. Use the number in the direct search above to inspect the item and its technical characteristics.

FSG is the broad Federal Supply Group; FSC narrows it to a Federal Supply Class. The term lists narrow the product description in stages. Disabled lists become available as you complete the preceding step.

Prepare a batch of stock numbers

From Main Menu → Search by NSN/NIIN, choose Create a Batch Report. The Batch Reporting form lets you supply a list and choose the information to request for those items.

Batch Reporting with two example stock numbers entered

The example enters 6140014469506,8345002500919. Use full NSNs separated by commas, keeping leading zeros. The form allows up to 250 NSNs. Alternatively, Choose File accepts a text list with comma-separated numbers or one NSN per line. Prepare one input list and keep a copy for reuse.

Section	Information it requests
FLIS Header	Catalog identification. This is already checked and cannot be cleared on this form.
MCRL	Part-number references and the organizations associated with them.
ML-C	Management-list information, such as unit of issue, supply source and price.
Award History 5 Years	The five-year award-history selection.
Award History	The broader award-history selection.
Technical Characteristics	Item specifications, dimensions, materials and other characteristics.
Associated Docs	Related specification, standard and document references.
Substitutes	Listed substitute and interchangeability references. Review their conditions before relying on a substitute.
Moe Rules	Item management and acquisition-rule information.

Before selecting Create Report, keep a copy of any batch list you may need again. Submitting a nonempty list replaces the batch list saved for your account and downloads the selected report as an Excel file. Back returns to the preceding screen; it does not restore the previous batch list. Select the sections relevant to your research before requesting the report. For the meaning of the individual catalog sections, use the catalog and logistics guide. The batch form is separate from the single-item Create Report screen described below. Read the batch-workbook guide for examples of every worksheet and the meaning of its columns.

Continue from name and classification results

Choose the matching stock number from the item-name table, or select a NIIN after narrowing by FSG, FSC and stored item terms. Confirm the item identity before choosing its research buttons. The walkthrough below follows both paths with its recorded item examples.

Watch: Find and open an item through classification or item-name results

Read the item identity

Field	Meaning and use
FSC	Federal Supply Class: the first four digits of the full NSN. This example is 5305.
NIIN	The nine-digit National Item Identification Number. This example is 007262550.
Date Assigned	The catalog assignment date shown for the item.
Name	The item's catalog name. Use it to confirm what you are researching.
Shelf Price	The DLA shelf price shown with the catalog item. Here it is displayed as 000000001.48.
Last Award Price	The most recent award price displayed for the item: $0.96 in this example.
Last Award Date	The date associated with that displayed price: 02/11/26 here.

Shelf Price and Last Award Price are different figures. Open Award History to see the quantities, dates and suppliers associated with past purchases rather than using a price without its context.

Read the part references

The list contains Part No., Company and CAGE. A CAGE identifies the organization associated with the reference. Read the part number and organization together: 199-617 appears beside DORMAN PRODUCTS, INC., CAGE 72741. This example has 13 rows, including standards organizations as well as companies.

The linked CAGE 72741 opens the Vendor/CAGE Detail View for DORMAN PRODUCTS, INC., in Colmar, PA 18915. Use Back to return to the same item. Continue with the company profile guide for company research.

Export to Excel appears above the part-reference list. For additional reference classifications, choose MCRL.

Export the item reference list

The Export to Excel button above the item page's part-reference grid exports that grid. A separate verified example reached the item page through Main Menu → Machine Shops Opportunities → FSC 5305 — Screws → NSN 5305002061533. Its workbook has one sheet, Sheet1, with Part No., Company and CAGE in columns A–C and four reference rows.

The actual four-row part-reference export opened in Google Sheets

Part No. is the displayed reference number, Company names the organization on that row, and CAGE identifies it. Read all three together: part number 9409072 appears once with ALLISON TRANSMISSION INC / 73342 and again with GENERAL MOTORS CORP / 24617. The other rows are 5306002061533 / E.C.A ETABLISSEMENT CENTRAL DES / A00AM and 8350635 / U S ARMY TANK AUTOMOTIVE COMMAND / 19207. The workbook contains these part-reference fields; it does not export the item's prices, award dates, drawings or research-button panels. Return to the Machine Shops opportunity example to see how that item page was reached.
