Since IETF 87, the IETF Secretariat has provided language buttons (pins) for attendees to borrow and display on their clothing as a resource to other bilingual participants. This page is a compilation of all of the languages our community has requested and are currently available at the meetings. If you notice a spelling mistake on this page or if there is a language you would like added, please email the registrar at support@ietf.org.
