Accessibility Statement

The General Services Administration is committed to providing access to our websites for all visitors with disabilities. Section 508 is a federal law that requires agencies to provide individuals with disabilities access to electronic and information technology and data comparable to those who do not have disabilities, unless an undue burden would be imposed on the agency.

If you have a problem viewing any material on, or another GSA website, while using assistive technologies, please contact our Section 508 coordinators at or 202-208-0799 for assistance. You may also send your concerns directly to the page owners by locating the contact(s) on each page. In your email please indicate the nature of your accessibility problem, the preferred format in which you want to receive any materials, and your contact information.
