In order to verify if a Sign with Singpass signature is valid, see here.

From February 2025 onwards, some Singpass Signing Certificates will be issued by a new Root CA. Please ensure that you load both Root CA Certificates in your Adobe Acrobat Reader in order to validate your documents.

Before that, the Singpass root signing certificates must be installed on your device. If you do not have the 2 Singpass root signing certificates on your device, please follow the steps in Sign with Singpass' guide.
