The American subsidiary of the PDF Association has been authorized by the American National Standards Institute (ANSI) to act as administrator of the Technical Advisory Group for the USA. The Technical Advisory Group belongs to the ISO Technical Committee (TC) 171, Subcommittee (SC) 2, which focuses on PDF format, PDF variants, including PDF/A and PDF/UA, and related file formats. The PDF Association thus replaces the 3D PDF Consortium, which held this function from 2017 to 2020.
