EN 301 549 and VPAT are often mentioned in the same conversation, especially when organizations buy software, websites, or other digital tools and need proof of accessibility. While they’re not the same thing, they work together in a practical way: EN 301 549 defines what accessibility requirements apply (in the EU context), and a VPAT documents how a specific product conforms (commonly used in procurement and vendor evaluation).
If you’re responsible for compliance, procurement, or product accessibility, understanding this relationship helps you avoid a common pitfall: treating a VPAT as a “certificate” rather than a structured disclosure that still needs validation through testing and continuous monitoring.
EN 301 549 is the European harmonized standard for accessibility requirements for ICT (Information and Communication Technology). It supports accessibility in public procurement and broader compliance initiatives, covering areas like:
In practice, EN 301 549 references the WCAG success criteria for web content (commonly WCAG 2.1 AA in many implementations) and expands into additional requirements for software, documents, and other ICT elements. If you need a clear grounding in WCAG before mapping to EN 301 549, the plain-language explainer WCAG in Plain English is a useful starting point.
Many organizations use EN 301 549 as a baseline when purchasing digital products because it provides a consistent set of expectations. Instead of vendors claiming “we’re accessible,” buyers can request evidence aligned to the standard and compare products more fairly.

A VPAT (Voluntary Product Accessibility Template) is a standardized format vendors use to report accessibility conformance. VPATs are most closely associated with U.S. procurement, but they’re widely used globally because they provide a structured way to describe accessibility support and known gaps.
To understand VPAT basics and procurement use, see What Is a VPAT?. For a deeper breakdown of what the report includes and how to interpret it, VPAT Report: What It Is, What It Includes, and How to Use It offers a practical overview.
When people say “EN 301 549 VPAT,” they usually mean one of these scenarios:
The key point: EN 301 549 is the standard; a VPAT is the disclosure document. A VPAT can support EN 301 549 procurement, but it doesn’t replace testing, remediation, or ongoing governance.
Accessibility reports vary widely in quality. If you’re evaluating vendors—or producing your own documentation—look for clarity, specificity, and test evidence.
Automated tools are useful, but they can’t verify many requirements (keyboard usability, meaningful focus order, correct alternative text quality, error prevention, etc.). A credible report typically references:
It’s normal for products to have issues. What matters is whether the report describes them accurately and offers:

If every row says “Supports” but the notes don’t explain how, treat it as a risk. Ask for test artifacts (sample findings, screenshots, or issue trackers) and confirm the test scope.
A report may claim WCAG conformance, but real users still encounter blockers (e.g., modal dialogs trapping focus, unlabeled controls, broken error messaging). Require hands-on validation, especially for critical user journeys like login, checkout, form submission, or dashboards.
Overlays/widgets can help with certain usability enhancements, but they don’t automatically fix code-level issues or guarantee compliance. Sustainable accessibility depends on design, development, QA, and content practices.
Whether you’re a buyer evaluating vendors or a product team preparing for procurement, accessibility compliance is easiest when it becomes an ongoing process, not a one-time document.
Map your obligations (e.g., EN 301 549 + organizational policies) to delivery requirements. For SaaS teams managing frequent releases, scaling this is crucial—see Digital Accessibility for SaaS Companies for a product-oriented approach.
Start with high-impact barriers (keyboard access, form labels, focus visibility, contrast, error identification). Tools like Corpowid (corpowid.ai) can help organizations run automated accessibility audits and monitoring to catch regressions early, while teams handle the deeper manual testing and remediation workflow.
Keep your VPAT (or equivalent conformance report) updated as features change. Also maintain an accessibility statement and support process. Corpowid (corpowid.ai) can streamline creating and updating accessibility statements and tracking issues over time, which helps when procurement asks for “current” evidence rather than last year’s report.

Even when EN 301 549 is framed as an EU standard, accessibility expectations increasingly show up in policies and procurement requirements beyond the EU. Universities and public institutions, in particular, often face a mix of legal obligations, stakeholder expectations, and procurement scrutiny. For context on local requirements impacting universities, read Türkiye Digital Accessibility Circular: What Universities Need to Do.
EN 301 549 sets the accessibility requirements; a VPAT is one of the most common ways vendors communicate conformance. Used well, VPATs help procurement compare options and reduce risk—but they’re strongest when paired with independent validation and continuous accessibility practices across design, development, and content.
