The Adobe Approved Trust List (AATL) is a program that enables millions of people around the world to digitally sign documents in Adobe Document Cloud solutions using the world’s most trusted digital IDs. The Certificate Authorities (CAs) and Trust Service Providers (TSPs) on this list issue certificate-based digital IDs and timestamp services that are used to comply with the most stringent legal and regulatory requirements in the world, such as the EU eIDAS regulation and the SAFE-BioPharma standard. Adobe digital signature solutions also work with every accredited provider offering qualified trust services listed in the European Union Trust List (EUTL).

Get your certificate-based digital ID or timestamp service from one of the providers below, and start signing documents securely with Adobe Acrobat Reader DC, Acrobat DC or Adobe Sign.
