Section 508 binds federal agencies. It reaches you through procurement.

The Revised 508 Standards incorporate WCAG 2.0 at Level A and AA and bind federal agencies, not private vendors — but an agency that must buy conforming technology will ask you how your product conforms.

Read on Section508.gov and the U.S. Access Board's ICT standards page, 11 September 2026. The Board cites the standard as Web Content Accessibility Guidelines (WCAG) 2.0, W3C Recommendation, December 11, 2008. As read on that date, no update to WCAG 2.1 or 2.2 was announced.

Three facts that resolve most Section 508 confusion

Taken from Section508.gov and the U.S. Access Board's own ICT pages, read on 11 September 2026.

ItemWhat the sources say
It applies to federal agenciesWhen they develop, procure, maintain or use electronic and information technology. Procure is the word that makes it a supplier question.
It incorporates WCAG 2.0 A and AACited by the Access Board as the W3C Recommendation of 11 December 2008, applied to electronic content, software interfaces and support documentation.
It covers more than websitesDocuments, support materials, hardware and non-web software — mostly out of reach of any web scanner.

What testing honestly contributes

Three things worth having before anybody writes a remark, and one thing we will not do.

What this does not do

It is not legal advice.
We build testing tools. Whether Section 508 reaches your contracts is a question for a qualified adviser, not a scanner vendor.
We do not produce or sign a VPAT.
No conformance report, no certification, no audit letter. An Accessibility Conformance Report is a vendor self-assessment that nobody certifies, and it is something we deliberately do not sell.
A scanner covers the web clauses only.
Documents, support materials, hardware and non-web software are all in scope for the standard and out of scope for a web scan.
A clean scan is not conformance.
Automated rules reach a minority of the criteria. The rest are reported as not checked and stay unknown until a person looks.
FAQ

Frequently asked questions

Section508.gov states that federal agencies must make their electronic and information technology accessible to people with disabilities, and that it applies to all federal agencies when they develop, procure, maintain or use that technology. Procurement is one of those verbs, which is how a rule aimed at agencies ends up in a supplier's inbox.

Clear the automated findings before you write a single remark

Run a scan against the product a buyer will actually open, fix what a rule can see, and start the report from a list of what is genuinely still unknown.
