What this scan does not cover
Automated checks like this one catch roughly 30–40% of WCAG issues, and this scan covers the homepage only. Manual testing is still required for keyboard flows, screen reader output and content quality.
A clean automated score is a floor, not a pass. If you need the issues an automated homepage check misses, run a full scan on your own site and work through the findings.
Why Accessibility Matters for USPS
Mail services are essential infrastructure. Users with disabilities need accessible package tracking, address change forms, and online purchasing to independently manage their postal needs without visiting physical locations.
What this means
Each failure above is a concrete barrier an automated tool could see without a human in the loop. This is not legal advice, but ADA complaints routinely cite exactly these WCAG 2.1 AA failures — contrast, labels, landmarks and keyboard access.
Business impact
Missed conversions from users who rely on assistive technology, plus higher support costs from inaccessible flows.
Compliance impact
ADA lawsuits often cite WCAG failures like contrast, labels, and keyboard access. Addressing the top issues closes the biggest gaps.
