Data sources

Every listing starts with public sources and is checked against the business’s own words. Here is how it comes together, and how to fix it when we get something wrong.

Where a listing comes from

  1. Sources

    • Public recordsGovernment lists, such as federal firearms licenses.
    • The business itselfIts own website and the pages it publishes.
    • People who know itOwners and visitors who add or correct a listing.

  2. Checked against each other

    A detail is published when a source supports it. When sources disagree, it waits.

  3. A listing that shows its sources

    You can see where each detail came from.

Spot something wrong? Your correction goes back to the check, and the listing updates when it holds up.

  1. A blank means not known yetIt doesn't mean zero, and it doesn't mean the business doesn't offer it.
  2. Their words are their ownA business's description of itself is not an endorsement from USA Arms.
  3. Reviewed is our date, not theirsIt's when we last checked the page, not when the business last changed.
  4. Each listing names its sourcesFollow them to the records and pages it was built from.

Fix or remove a listing

Owners and visitors use the same forms. A request goes to review; it doesn't change the listing by itself. Some license holders and instructors work from home, so if a listing raises a privacy or safety concern, tell us and we'll review it in good faith.

Licenses and data use

A federal firearms license shows who holds it, not that the place is a public shop.

Using USA Arms data beyond normal browsing needs our authorization; API access explains how to ask. Every public change is dated in the changelog.
