EN 301 549 vs Section 508
EN 301 549 (EN 301 549 — Accessibility requirements for ICT products and services, European Union (harmonised standard), 2014 (v3.2.1 current)) and Section 508 (Section 508 of the Rehabilitation Act, United States — federal government and federal contractors, 1998 (2017 Refresh)) are two of the most-referenced accessibility frameworks in digital compliance. This guide compares them side by side — jurisdiction, scope, conformance approach, penalties, and how a single audit can cover both simultaneously.
What is EN 301 549?
EN 301 549 is the harmonised European standard for digital accessibility, maintained jointly by ETSI, CEN, and CENELEC, that incorporates WCAG 2.1 AA for web and mobile content and adds requirements for hardware, software, documentation and support — and is the technical reference for both the European Accessibility Act and the Web Accessibility Directive.
Maintainer
ETSI / CEN / CENELEC
Jurisdiction and enforcement
European Union (harmonised standard). Referenced by EAA and Web Accessibility Directive.
What is Section 508?
Section 508 of the Rehabilitation Act requires US federal agencies, federal contractors, and recipients of federal funds to make their information and communications technology (ICT) accessible to people with disabilities, with conformance benchmarked against WCAG 2.0 Level AA via the 2017 Refresh.

EN 301 549 vs Section 508 — the key differences
The principal difference is jurisdictional: EN 301 549 applies in European Union (harmonised standard), while Section 508 applies in United States — federal government and federal contractors. EN 301 549 is maintained by ETSI / CEN / CENELEC; Section 508 is maintained by US Access Board. The standards differ on scope, conformance grading, and penalty structure — but a well-designed accessibility programme can satisfy both simultaneously by adopting the strictest applicable requirement and cross-mapping findings.
Scope
EN 301 549 covers: Web content, Non-web documents (PDF, EPUB), Software (native apps, OSes), Hardware (kiosks, devices), Documentation, ICT support services. Section 508 covers: Federal-agency websites and applications, Federal-contractor ICT, ICT procured with federal funds.
Penalties
EN 301 549: Inherited from referencing law (WAD or EAA per member state). Section 508: Procurement disqualification.
How to comply with both at once
Adopt the stricter applicable conformance level — typically WCAG 2.2 Level AA — as your engineering baseline. Audit against that baseline once, then cross-map findings to both EN 301 549 and Section 508 specific requirements. A single Accessibility Conformance Report (ACR) using VPAT 2.5 INT can document both.
When you might need just one
If you operate exclusively in European Union (harmonised standard) and have no cross-border procurement exposure, you may only need EN 301 549. The same applies in reverse for Section 508. For organisations selling cross-border, into the EU or US public sector, the safer default is to plan to both simultaneously.

FAQ
Frequently asked questions
Cited answers. Sourced. Updated as standards and case law change.
Is EN 301 549 stricter than Section 508?
Neither standard is uniformly "stricter" — they cover different regulatory domains. EN 301 549 is more prescriptive about web content; Section 508 about federal-agency websites and applications. For organisations exposed to both, a unified WCAG 2.2 AA baseline typically satisfies the technical requirements of both.
Can a single audit satisfy EN 301 549 and Section 508?
Yes. Both standards ultimately reference WCAG-aligned criteria. A combined audit with cross-mapped findings can produce documentation acceptable to both regulators.
Which jurisdictions enforce EN 301 549?
European Union (harmonised standard). Referenced by EAA and Web Accessibility Directive.
Which jurisdictions enforce Section 508?
United States — federal government and federal contractors. GSA, agencies, US Court of Federal Claims.
What happens if I am not compliant with EN 301 549?
Inherited from referencing law (WAD or EAA per member state)
What happens if I am not compliant with Section 508?
Procurement disqualification Contract termination or modification Bid protests at GAO and US Court of Federal Claims Reputational and downstream civil-rights exposure under Sections 501 and 504
