Classification systems

NAICS 2022 has a complete U.S. structure of codes and titles. The other four systems retain their clearly labeled partial reference sets until their structures and publication rights are separately reviewed.

Coverage register

Markets, without the guesswork

Active means the system has searchable records here. Registry means the market is tracked for future source review, not yet published as searchable code pages.

Method

Built for decisions,
not keyword stuffing.

Every result separates the official heading from our editorial explanation. Close alternatives stay visible so uncertainty can be inspected instead of hidden behind a single score.

01

Start with the activity

Describe the product or service creating most value—not the storefront, payment method or social platform.

02

Narrow the context

Choose the country and make the manufacturing-versus-retail or product-versus-service distinction.

03

Inspect alternatives

Read inclusions, exclusions and neighboring headings before using a result in a form or policy.

04

Confirm with the recipient

A tax agency, insurer, bank or statistical office can apply its own assignment rules. This tool is guidance, not an official assignment.

Good classification starts with good context

Describe the work.
See the trade-offs.
