    • Informative descriptions of infographics or diagrams

Testing for Accessibility Compliance

Design & Content Reviews

Validate Your Work

All design and development work is expected to meet Section 508, WCAG 2.0 AA, and USPS 508 standards. Incorporate accessibility validation into project workflows and iterative testing (i.e., as part of design, unit, integration, system, and acceptance testing). Required and optional reviews are intended to supplement and validate design and development team testing.

Required Review

Request a formal USPS 508 review by a designated USPS 508 reviewer under the USPS Section 508 Program Manager, as designated by the Vice President/Chief Technology Officer (VP/CTO). The USPS 508 reviewer will test your website or application according to the USPS Handbook AS-508A and report non-compliant issues.

Additionally, the USPS Digital Brand Marketing reserves the right to evaluate any design and development work whose accessibility standards compliance is questionable or about which accessibility complaints are received. Informal, iterative reviews from the USPS.com

Digital Content Team may be requested during design and developmentā€”as allowed by the USPS.com Manager.


Accessibility Remediation

If a website, application, or document does not meet applicable Section 508, WCAG 2.0 AA, or USPS 508 standards, the owner (or business driver), and their design and development team, are responsible for making the item compliant or providing an alternate accessible version.

USPS Digital Brand Marketing reserves the right to remove or unlink from a failed property that is not compliant, being fixed, or has no equivalent alternative.
