NIGP categories

Search state and local purchasing category records, then open one NIGP category to review hierarchy, related opportunities, contacts, and source-data context.

Click NIGP Categories, or open GovTribe, expand the sidebar if it is collapsed, expand Categories, and click NIGP Categories.

NIGP Categories is available on Launch Plus, Growth Plus, and Scale.

NIGP categories shows search controls, page actions, and NIGP category result cards.

Parent NIGP appears on result cards, but it is not a visible Add Filter option on this search page.

Sort options

When NIGP Categories opens without a search query, filters, or explicit sort, GovTribe may use recent activity and popularity signals to decide which categories appear first. Add search text, filters, or a specific sort when you want the order to match your review task.

NIGP category examples

A civil engineering category helps you confirm state and local purchasing context before reviewing related opportunities. See the Civil Engineering example in GovTribe.

NIGP category details show hierarchy and related state and local opportunity context.

Hierarchy and category context

The detail page shows the NIGP code, category name, parent or child status, and hierarchy controls. Use the hierarchy to compare broad purchasing families with narrower commodity or service categories.

State and local source context

NIGP categories connect to state and local procurement records as source-provided or mapped category context. Because source agencies do not all publish category data the same way, confirm the match against the record title, summary, buyer, source text, and related opportunities before treating the category as final.

Contacts

Contacts lists people connected to records associated with the NIGP category.

Contract Opportunities

Contract Opportunities lists state and local contract opportunities associated with the NIGP category.

Common questions

For general fixes for too many results, no results, unrelated results, broad Semantic Search matches, or filters that narrowed the search too much, see Troubleshoot search results.

What does NIGP classify?

NIGP category data type records describe state and local commodity and service categories. Use NIGP when researching how state and local sources classify what is being bought. It is separate from federal NAICS industry coding and federal PSC product or service coding. See Choosing category systems.

How should I use exact NIGP codes?

You can search a known code or category name, but the result card and NIGP Hierarchy dialog are the safer way to confirm parent and child context. The hierarchy dialog opens linked parent and child category codes so you can move between broad purchasing families and narrower categories.

How does NIGP Hierarchy help?

NIGP Hierarchy shows how a state or local purchasing category fits inside broader and narrower commodity or service families. Use it to move from a broad purchasing family to a more specific category, especially when source agencies use category wording differently.

How does NIGP relate to state and local records?

NIGP categories connect to state and local procurement records as commodity or service context. State and local sources do not all provide the same category system, so use the category match with the title, summary, source text, buyer, and related record context before treating it as final. See State and local contract data model.
