The Adobe Approved Trust List (AATL) is a program that enables millions of people around the world to sign documents in Adobe Document Cloud solutions using the world’s most trusted digital signing certificates. The certificate authorities (CAs) and trust service providers (TSPs) on this list issue digital signing certificates and timestamp services that can be used to comply with legal and regulatory requirements around the world, including the EU eIDAS regulation. Adobe’s digital signatures also work with every accredited provider offering qualified trust services listed in the European Union Trust List (EUTL).
Get your digital certificates or timestamp service from one of the providers below, and start signing documents securely with Adobe Acrobat Reader DC, Acrobat DC, or Adobe Acrobat Sign.
