The Adobe Approved Trust List (AATL) enables people worldwide to sign documents in Adobe Document Cloud solutions using digital signing certificates that are trusted globally. The certificate authorities (CAs) and trust service providers (TSPs) on the list issue digital signing certificates and timestamp services. You can use the certificates and timestamp services to comply with global legal and regulatory requirements, 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 on the list, and sign documents securely with Adobe Acrobat Reader, Acrobat, or Adobe Acrobat Sign.
