How do I add NAICS autocomplete to my app?
NAICS is a free AutoSugges reference list of 2,125 items. Query it with your publishable key as the key parameter and the typed text as q, after at least two characters. Results come back pre-ranked from the edge, ten by default, ready for the AutoSugges React, React Native or HTML component.

Field schema
2,125 items, across 5 hierarchy levels: sector, subsector, industry_group, naics_industry, national_industry.
| Field | Type | Meaning |
|---|---|---|
| value | string | The canonical, unique value — what a query resolves to. |
| displayValue | string | The locale-resolved label a suggestion renders. |
| description | string, optional | Free-text detail shown beside the item. NAICS uses it for the ancestor breadcrumb; not every dataset sets it. |
| parentSourceId | string, optional | The parent item in the source’s own key space, for a hierarchical dataset. |
| hierarchyLevel | string, optional | Which level of the hierarchy this item sits at. |
| displayOrder | integer | Curated display order, distinct from relevance rank. |
| aliases | string[] | Alternate spellings that resolve to this item. |
| metadata | object | Dataset-specific fields — e.g. NAICS’s `code`/`level`/`trilateral`, or a country’s `alpha2`/`alpha3`/`numeric`. |

Frequently asked questions
- What is in the NAICS dataset?
- The 2022 North American Industry Classification System: 2,125 industry codes across five levels, searchable by code or by title. Published by the U.S. Census Bureau. It has 2,125 items. Its source is U.S. Census Bureau. Authority: Authoritative. Licence: U.S. Government work. Not subject to copyright protection in the United States (17 U.S.C. §105). The Census Bureau requests citation rather than imposing licence terms. Refresh cadence: Every five years, on the NAICS revision (2017, 2022, 2027).
- Is the NAICS dataset free?
- AutoSugges-published free datasets are never priced on their own — every plan includes all of them. What a plan prices is how many queries you may make, not which free list you may query. A few catalog entries are licensed from a third party or supplied by you, and those carry their own access terms, shown on that dataset's own page.
- How do I query NAICS?
- Call GET /v1/query with your publishable key as the key parameter and the typed text as q, or mount the AutoSugges component for React, React Native or HTML. The runtime answers from the edge and never reads a database.
- What is the minimum number of characters before a query runs?
- Two by default. A list owner can change the minimum, but it can never be 1. The client reads the real value from bootstrap and sends no request below it, so do not hardcode it.
- How long does the client wait after typing before it queries?
- 150 milliseconds by default. The value is delivered through bootstrap and a list owner can raise it, so the client uses the policy value rather than a constant.
- What happens when my query quota runs out?
- The runtime returns a structured quota_exceeded response that carries no items and no placeholder suggestions, so exhaustion is never mistaken for no results. Render it from the typed error code and prompt an upgrade.
